At Hillcrest Golf & Country Club in Hollywood, the fairways and greens are irrigated with 'reclaimed' waste water.

South Florida has suffered through some dreary declines of late — home values, paychecks and the Miami Dolphins, for instance.

But in the case of the public thirst for one precious commodity — fresh water — the decline has actually turned into a major money-saving plus.

The 53 water utilities serving Miami-Dade, Broward, Palm Beach and Monroe counties pumped about 83 million fewer gallons a day in 2010 than they did in 2000 — despite a population that grew by some 600,000 over the decade — according to a new draft analysis produced by the South Florida Water Management District.

Do the math and it adds up to South Floridians using about 20 percent less water each day for drinking, bathing and sprinkling yards per person than they did a decade ago. That’s about 30 billion gallons over the course of a year, enough unused water to fill 45,900 Olympic-sized swimming pools.

It’s an unexpected but entirely welcome drop-off in public demand in a region that only a decade ago was worried about taps running dry in relentlessly sprawling suburbs.

“It’s not a surprise that it went down,’’ said Mark Elsner, administrator of water supply development for the water management district. “It’s a surprise it went down so much.’’

WHAT’S BEHIND IT

Though water consumption per person has been declining for decades, water managers point to a combination of factors that are accelerating the trend. They include newer water-efficient toilets and other fixtures, tougher restrictions on lawn irrigation and stepped utility rates designed to make customers pay a premium for excessive water use.

Water managers and state and local environmental regulators have pushed conservation programs and also demanded that utilities expand use of “reclaimed” wastewater — often by using it to irrigate parks and golf courses.

At Hillcrest Golf & Country Club in Hollywood, for instance, every drop from the sprinklers is recycled wastewater — cheaper and in totally unrestricted supply.

“We have a very good deal for water. We could use a million gallons or 10 gallons and we pay the same amount,’’ said Lewis Rissman, Hillcrest’s general manager. “The city of Hollywood doesn’t even know what to do with all their reclaimed water.’’

Clearly, South Florida’s economic downturn, housing market collapse and flattening population growth have contributed to the slaking thirst as well.

“There are a lot of things working together,’’ said Elsner, whose agency oversees the water supply for 16 counties stretching from south of Orlando to Key West. “What you’re seeing is a conservation ethic being developed. People are understanding the value of water.’’

What the decline in demand from public utilities does not mean is South Florida is in the clear when it comes to water shortages

South Florida depends on wildly varying annual rainfall to replenish its underground aquifers and Lake Okeechobee. Right now, for example, an unusually dry winter has left ground water levels lower than normal.

The district’s long-term planning analysis, revised every five years with new consumption and population figures, also covers only four counties in the region and doesn’t track similar trends for agriculture, which consumes an estimated 37 percent of the region’s water. It also doesn’t account for some critical future demands — such as the massive volumes of water needed to help restore the Everglades. The draft study predicts the four counties will still need to expand the public water supply by 18 percent by 2030.

But improved conservation has eased pressure on traditional public water supplies and utilities contemplating new, far more expensive water systems designed to reclaim wastewater and tap other new sources, from deep aquifers to sea water.

SCALING BACK

The drop-off has been significant enough that Miami-Dade’s Water and Sewer Department has been able to scale back projects considered essential only five years ago, saving the utility — and its customers — hundreds of millions of dollars.

In 2007, Miami-Dade, which had historically relied almost entirely on the cheap, clean Biscayne Aquifer, was forced to draw up a $1.6 billion expansion plan to serve a then-booming population. Under pressure from water managers, who warned that drawing more from the underground supply could hurt regional water supplies, the Everglades and Biscayne Bay, Miami-Dade designed projects to tap the deeper brackish Floridan aquifer or to treat wastewater.

Bertha Goldenberg, assistant director of the water and sewer department, said the county has since been able to cancel or defer a handful of projects, including one that would have piped highly treated wastewater back into the ground near Zoo Miami to increase ground water supplies.

“We basically saved $300 million by changing that,’’ she said.

Alan Garcia, director of Broward County’s water and wastewater services, said the decline has allowed the agency to push back a $46 million project to tap the Floridan until at least 2023 and explore other potentially cheaper options for the future, such as teaming up with other Broward and Palm Beach utilities in constructing a massive reservoir.

Garcia said county figures show per person usage falling sharply in some areas, down almost by half between 1990 and 2008 in one area that includes Lighthouse Point and parts of Pompano Beach.

“People have finally started to see they don’t need to water their lawns four or five days a week,’’ he said. “It’s expensive water and they don’t need to use it.’’

Miami-Dade’s Goldenberg also points to irrigation restrictions the district first imposed in 2006 during a severe drought as a major factor in the decline, with county usage dropping by 20 gallons a day per person over the following two years. In 2010, both Miami-Dade and Broward made twice-weekly lawn watering rules permanent.

Miami-Dade programs to offer rebates and exchanges for high-efficiency toilets and shower heads and to improve homeowner associations’ irrigation systems also combined to save nearly 8.5 million gallons a day last year, according to a water department report completed in April.

The district analysis shows that, based on 2010 figures, Miami-Dade remained the largest consumer of the public water supply, slurping some 347 million gallons a day. Broward trailed with 217 million gallons a day, followed by Palm Beach County with 207 million gallons and Monroe with 16 million gallons.

But Palm Beach County’s agricultural industry, dominated by sprawling sugar farms, made it the thirstiest county overall. Farms, which draw from their own wells and pumps, pushed Palm Beach’s total daily demands to over 600 million gallons. Miami-Dade’s combined farm and public total runs just over 400 million gallons a day, according to the report.

Measuring by usage per person, Palm Beach recorded the greatest decline between 2000 and 2010, at 28 percent, followed by Broward at 19 percent and Miami-Dade at 17 percent. Miami-Dade’s updated numbers, which include figures through 2011, show a 21 percent reduction since 2000.

THIRSTY MONROE

Officially, Monroe ranked far and away as the thirstiest county per person at 198 gallons per day in 2010 but water managers said that number was heavily skewed by tourists in the Florida Keys, who use much of the water but aren’t included in the calculations.

Lower population projections also have eased the pressure to expand water systems. The last time the district produced its analysis, in 2006, when South Florida was in the midst of a super-heated housing boom, water managers calculated the four counties would be using nearly 2.3 billion gallons of water a day by 2025 for everything from home faucets to farming.

That estimate is now down by some 400 million gallons — for 2030, five years later.

“I don’t think the question is are we going to run out of water but are we going to run out of less expensive water,’’ said Elsner, of the water management district. “What this does is extend the traditional fresh water sources further down the road.’’

Miami-Dade now believes it can cover much of its future demand through 2030 with a plant in Hialeah already under construction and expected to be completed later this year that will tap the Floridan and a second plant in South Miami that is being designed to use less expensive technology.

“We’re a lot better off than we were in 2005,’’ Goldenberg said. “Our demands were above our allocations so we were really in a crisis.’’

Everglades scientists play risky game of tag with near-extinct predator

By SUSAN COCKING

Sean McNeil and Jordan Kahn / PressLaunch.US

Researchers from the University of Florida captured, tagged and released two sawfish in the 13-foot range near East Cape Sable in Everglades National Park as part of a larger recovery project for the endangered species.

The boat captain and the scientist wielded their lasso like seasoned cowboys instead of fishermen. A good thing, since their lives literally depended on it: roping an upset, 13-foot-long, prehistoric creature waving a double-toothed saw in the water is just as dangerous as grabbing a bull by the horns.

“There’s a swing,” Captain Jim Willcox warned as the saw slashed the air. “Careful, it’s pretty green.”

But Willcox and Yannis Papastamatiou, a University of Florida scientist, managed to secure the line around both the saw and the tail of their quarry: an endangered smalltooth sawfish, the rarest marine species in U.S. waters. Now the huge brown creature lay quietly alongside their skiff near East Cape Sable in Everglades National Park, enabling them to safely complete their research mission.

“He’s a good boy!” said UF research assistant Bethan Gillett, who had caught the giant fish on a rod and reel moments earlier.

The point of this hazardous maritime rodeo is for researchers from the Smalltooth Sawfish Recovery Team to learn as much as they can to help bring back one of the top predators in the marine ecosystem — nearly wiped out through its entire range over the past century.

“These guys started disappearing before we as biologists started figuring out they were going,” said George Burgess, who runs a sawfish database at the University of Florida’s Museum of Natural History in Gainesville.

Once common from New York south to Florida and west to Texas, these huge members of the ray family that can grow to 25 feet are rarely seen today, except for the waters of Everglades National Park and the Keys. Not a lot is known about their life history, but scientists say they may live 25 to 30 years, reaching sexual maturity after about 10 years. Females give birth to litters of 15 to 20 pups.

With its slow growth and late maturity, the smalltooth sawfish met its demise decades ago by becoming entangled in gill nets, being slaughtered by collectors of its bill, and squeezed by shrinkage of its shallow mangrove habitat. It was declared an endangered species in the United States in 2003. Its cousin, the endangered largetooth — formerly found in the Atlantic — now is functionally extinct in U.S. waters, according to Burgess.

Burgess says recovery of the smalltooth will take a very long time.

“Even with a total ban on death, it will take 100 years, and we’re 10 years into that process, so we’ve got 90 years to go,” he said.

Sawfish numbers are so beaten down that even scientific experts like Burgess and colleagues from the National Marine Fisheries Service and Florida Fish and Wildlife Conservation Commission must obtain a federal permit to handle the species. Anyone else who molests or harasses them faces a possible $10,000 federal fine.

This year, Burgess had a permit to tag 11 sawfish, which he did over the past couple of months with help from Willcox — a veteran Islamorada light-tackle guide — and several UF colleagues. They deployed the final two sets of tags on April 27 near East Cape Sable on two males in the 13-foot range. Both swam forcefully away when the procedures were completed.

Papastamatiou drilled holes in the animals’ tough dorsal fins and fastened a cigar-shaped satellite pop-up tag, an acoustic transmitter tag and a small streamer tag with the research lab’s phone number. The satellite tag records water temperature, depth and light levels at short intervals, then pops off after five months, broadcasting the accumulated data to a satellite, which sends it to the scientists’ computers.

The acoustic tag beeps a signal to underwater listening stations that tell how many times the sawfish passes through the area. The three tags are intended to back each other up.

Willcox and the scientists have been catching and tagging sawfish in the park for about three years — not enough time to draw conclusions about the animals’ movements or growth rates. Their ability to continue the research is imperiled by money problems: Federal funds are running dry, so they’re seeking private donations.

“It’s going to be a long haul,” Burgess said. “We can’t grow weary of the fight. Hopefully, our children and grandchildren will have a shot at this down the line.”

One thing in the sawfish’s favor is its charisma — a giant, brown apex predator that slashes its prey, mostly fish and some crustaceans, with its deadly bill. A recent study by scientist Barbara Wueringer of the University of Queensland in Australia found that the animals have a “sixth sense” in their bills — a series of pores that can detect movements or electrical fields of hidden fish or crabs.

The sight of a sawfish is awe-inspiring, Willcox says.

“When people see that for the first time, they feel like they’ve gone back in time,” he said. “It’s not something you want to mess with casually. That bill can come up vertically and take your head off. For me, it’s like fishing in a tournament and getting a victory. It’s about as big a rush as you can get in fishing — or anything in life.”

These photographs were taken under the authority of NMFS Permit No. 13330.

Peace may finally be at hand in the decades-long Everglades dirty-water war.

Eight months after Gov. Rick Scott flew to Washington to extend a political olive branch and personally pitch Florida’s latest plan for stopping the flow of polluted farm, ranch and yard runoff into the Everglades, state and federal negotiators are on the verge of an accord expected to be hailed by both sides as a major milestone.

A settlement crafted with the goal of resolving two protracted and paralyzing federal lawsuits — one goes back almost a quarter century, the other eight years — could be soon finalized, possibly within the month, according to officials on both sides of the confidential negotiations.

The agreement would commit Florida to a significantly expanded slate of Everglades restoration projects pegged at an estimated $890 million. Still, that’s a considerably smaller price tag than a $1.5 billion plan drawn up by the U.S. Environmental Protection Agency that a Miami federal judge has threatened to impose.

Most key technical issues — such as the size of additional artificial marshes used to scrub dirty, nutrient-laced storm runoff that has poisoned vast swaths of the Everglades — have been largely sorted out. But both sides cautioned the deal could still be delayed as negotiators work through the nuts and bolts of rolling out, implementing and enforcing a complex and likely controversial agreement.

Environmental groups and sugar growers have heard increasingly encouraging reports from negotiators over the past few months, though they have not been briefed on key details. But they agree the new cleanup blueprint that emerges will stand as a landmark in the costly, contentious legal and political battles to revive the struggling, shrunken River of Grass.

“It would be huge for everyone,’’ said Gaston Cantens, a vice president for Florida Crystals, one of the region’s largest sugar growers. “For a business, whenever you can have stability and certainty, then you can make long-term plans with confidence.’’

Environmentalists are reserving judgment, with some bracing for a deal they fear will be a compromise that might fall short of providing the Glades the pristine fresh water it needs and will push cleanup deadlines, already repeatedly delayed, back by years.

David Guest, an attorney for EarthJustice who represents several environmental groups in a 24-year-old lawsuit brought by the federal government that first forced Florida to deal with Glades pollution, said he has heard enough about the framework of the deal to know he’ll find plenty to question.

But even Guest acknowledges, “It’s absolutely going to be progress, there is no doubt about that.”

The South Florida Water Management District, which oversees restoration projects for the state, responded to questions with a statement, saying the state plan was “scientifically sound, economically feasible and would bring about long-term protection for America’s Everglades.’’

“We’ve had productive dialogue with our federal partners and have made significant progress toward an agreed-upon approach. However, there are some outstanding issues that are important to Florida.” For both the Obama and Scott administrations, finalizing a major Everglades deal would represent a political win and a rare example of bipartisan cooperation. It would be particularly notable for the governor, a tea party-backed, anti-regulation Republican healthcare executive who infuriated environmentalists in his first year in office by slashing environmental programs and gutting much of the state’s grown management oversight.

With the state facing the threat that U.S. District Judge Alan Gold would impose the $1.5 billion EPA cleanup plan on the state, Scott last October flew to Washington to pitch Florida’s alternative plan, meeting with high-ranking White House officials, including Interior Secretary Ken Salazar and EPA Administrator Lisa Jackson.

He has continued campaigning since, in meetings and letters, including a Feb. 1 letter to President Barack Obama discussing encouraging settlement talks and stressing a message repeated in a state court brief filed this month requesting more time for negotiations: that the state’s time and taxpayer’s money would be better spent on projects than “pointless, expensive and time-consuming litigation.’’

In an April 5 response to Scott, EPA administrator Jackson echoed the upbeat tone, noting “we share a common desire to take advantage of the opportunity in front of us for quick, historic progress towards clean water for the Everglades.’’

Though four federal agencies initially found the state’s plan inadequate, the state has made a number of tweaks and additions during negotiations, officials said, adding some 8,400 more acres of treatment marshes — still far less than the 42,000 additional acres the EPA had proposed. In addition, the state plan calls for expanded water storage in a string of new “flow equalization basins’’ intended to keep the marshes more effective by limiting flooding or damaging dry-downs.

To save money, land swaps are being considered and water managers also intend to convert a massive reservoir that water managers halted two years and $272 million into construction in 2008 would be turned into one of new, shallower basins.

The nearly $900 million in projects would add to the $1.8 billion the state has already spent to construct a 45,000 acres of existing marshes, with an additional 11,000 acres scheduled to come online later this year. But that massive network hasn’t been enough to meet the super-low standards needed to protect the sensitive Glades ecosystem from phosphorous, a common fertilizer ingredient that drains off farms and yards with every rainstorm. It fuels the spread of cat tails and other exotics that crowd out native plants.

Though Scott has earned praise from some environmentalists, Guest, the EarthJustice attorney, isn’t among them, arguing the governor didn’t lead so much as he was pushed by courtroom defeats and mounting pressure from two federal judges.

Gold, in a 2004 suit brought by the Miccosukee Tribe and the environmental group Friends of the Everglades, has issued a series of rulings blasting the state and federal agencies for “glacial delay’’ and repeatedly failing to enforce water-pollution standards tough enough to protect the Everglades. In 2010, he ordered the EPA to draw up a cleanup plan that water managers said they couldn’t afford.

U.S. District Judge Federico Moreno, who oversees the original 1988 cleanup suit by the federal government, has expressed similar frustrations and urged both sides to come up with a viable plan.

Barbara Miedema, vice president of the Belle Glade-based Sugar Cane Growers Cooperative, said she expects it will still take a while to nail down the deal. With multiple federal and state agencies, more than a half-dozen environmental groups, the Miccosukee Tribe and two federal judges involved, there are numerous legal, practical and political hurdles to clear, she said.

“We hear they are close, but we have been hearing they are close for months,’’ she said. “A lot of signs say it’s likely. I’m not betting on it.’’

Pythons Swallow Whole Deer in Florida, $6 Million Tab

By Mike Di Paola - May 3, 2012 12:01 AM ET

The meandering trail in the Everglades marshlands was made by alligators, I’m told, so be careful. There’s also poisonwood, fire ants and the recently added Burmese python.

“It’s really a very harsh place to work,” says Kristen M. Hart, a research ecologist for the U.S. Geological Survey and a close follower of the python, which has invaded the Everglades in startling numbers.

“We don’t know how many there are,” Hart says, “and that’s ultimately the question everyone wants to know.”

She reckons tens of thousands in the Everglades, but allows the number could be higher: “I think there could be more here now than in their native range” of Southeast Asia.

I’m with Hart and other wildlife biologists tracking an 8- foot, 20-pound (2.4 meter, 9-kilo) female python that had been captured and implanted with radio transmitters a few weeks earlier.

There are many reasons why the python thrives in the Everglades, beyond the obvious fact that it eats just about anything, while almost nothing eats it.

Pythons prey on mammals, other reptiles, fish and birds. The invaders in Florida have consumed everything from the endangered Key Largo woodrat to the threatened American alligator.

Last October, a snake in the Everglades was found to have swallowed a 76-pound (34-kilo) deer. Another specimen was discovered with an adult alligator bursting from its insides -- a tooth-and-claw encounter neither animal survived.

‘Dramatic Declines’

In January, the proceedings of the National Academy of Sciences published a study showing “dramatic declines” of mammal populations in southern Florida -- raccoon, opossum, bobcat, deer and rabbit -- all believed to have become snake food.

It is not known how the Burmese python was introduced to the Everglades. Large pythons -- almost certainly escaped or discarded pets -- have been spotted here since the 1980s. By 2000, however, it was clear that the snakes were not escapees, but a growing, breeding population.

“People think this is a Florida thing,” says Ken Warren of the U.S. Fish and Wildlife Service. “But there have been reports of large constrictors found in Texas, Georgia and California, as well as the Virgin Islands and Puerto Rico. This is bigger than Florida.”

Federal agencies and local governments have spent more than $6 million since 2005 to figure out how to control the snakes. Eradicating them is not a realistic goal; managing them is imperative. To that end the biologists are gathering data.

‘Control Strategies’

“What we’re ultimately trying to do is understand the biology,” Hart says. “How do you exploit what you know to really knock them down? Where might the pregnant females be? What is their preferred diet? That’s the kind of information we need to design control strategies.”

Besides the python we’re tracking, there are seven other snakes implanted with transmitters, including a female weighing 140 pounds. Their movements are tracked almost daily, either on foot or from small planes.

Meanwhile, lawmakers are doing the legislative equivalent of closing the barn door after the horses have fled. Earlier this year, the U.S. House Judiciary Committee approved a bill to widen the ban on imported snakes to include the Burmese python and other large serpents.

Big Babies

Aside from their indiscriminate diet and unchallenged position in the food chain, Burmese pythons have other survival advantages. Hatchlings are big -- two to three feet long when they wriggle out of their eggs -- and so are not easy pickings for a potential predator. It is believed that females can reproduce without a male partner.

They are excellent swimmers, can survive for extended periods in salt water if they have to, and are barely visible in the Everglades habitat, so can sneak up on dinner with ease.

“I think she’s right between us,” the biologist next to me says. He points his antenna at my feet, which I can’t see in the murky water. Nor can I see the snake, until the slightest movement betrays her location, about a yard away.

Her head looks to be the size of my fist. Her colors aren’t brilliant but they are beautiful, a delicate patchwork of tawny lines that match the grasses all around us.

The biologists record the salient details: habitat, predominant flora, GPS coordinates, and so on. The snake doesn’t flee at our approach. For an invasive species, she looked very much at home.

Though the previous washed-out weekend might have suggested otherwise, South Florida’s rainy season has not yet begun — at least officially.

But when it does start sometime this month, expect it to be a bit wetter than normal, forecasters and water managers said Thursday.

South Florida’s wet season, which usually begins around May 20 and runs until mid-October, typically produces about 70 percent of the regional rainfall. Those five months help keep the Everglades healthy and water supplies recharged or — if the rains don’t show — produce droughts that kill crops and lawns.

Robert Molleda, a meteorologist with the National Weather Service’s Miami office, said a number of indicators, including the easing of the global La Niña weather pattern, point to a wetter season into June. The remaining months appear likely to be close to average.

With the region still showing lingering effects from an unusually dry fall and winter, a bit more rain would help, said Susan Sylvester, chief of water control operations for the South Florida Water Management District, which oversees the water supply for 7.7 million people from Orlando to Key West.

Above-average April rainfall, much of it delivered last weekend, helped Miami-Dade, Broward and Palm Beach counties but only provided a bit of recharge for Lake Okeechobee, which serves as the region’s water barrel.

Overall, the 16-county district’s rainfall deficit since November is about 5.5 inches. Lake Okeechobee was at 11.63 feet above sea level Thursday, about two feet below its average mark for the date.

The typical wet season produces about 35 inches of rain but one tropical storm or hurricane can easily push the figure higher.

With the workload of developing new nutrient water quality rules seemingly in the rear view mirror, the Florida Department of Environmental Protection is moving forward on some other potentially controversial water quality issues.

DEP is responsible for protecting the quality of Florida’s drinking water as well as its rivers, lakes, wetlands and springs. The Federal Clean Water Act requires states to publicly review and update their water quality standards in what is called a "triennial review." 

The department has scheduled hearings for later this month in West Palm Beach, Orlando and Tallahassee to consider its "human health criteria" involving exposure to chemicals through fish consumption.

DEP was conducting a similar review in 2008 before some environmental groups filed a federal lawsuit challenging the state's lack of numeric limits for nitrogen and phosphorus. That lawsuit led the U.S. Environmental Protection Agency to set limits for nitrogen and phosphorus in Florida waterways, which prompted DEP to adopt replacement rules.

"That just became all-consuming," said Drew Bartlett, director of DEP's Division of Environmental Assessment and Restoration. "Now that we put that to rest, we can shift those resources consumed by the numeric nutrient criteria back onto this issue. We decided to pick it straight right back up."

The Legislature waived approval of those rules in February and the state sent them to the EPA for review. Environmental groups including the Conservancy of Southwest Florida, the Florida Wildlife Federation and the Sierra Club have a legal challenge pending at the Division of Administrative Hearings.

In 2009, the Clean Water Network petitioned the federal EPA to set human health criteria for fish consumption. Other environmental groups had sued in 1995, arguing that previous human health criteria were based on low fish consumption rates by Floridians.

DEP has conducted studies and determined that Floridians do eat more fish than those in other states, so proposed new human health criteria will have to reflect that, Bartlett said.

"It is going to become more stringent than it is currently on the books for all of those (pollution) parameters," he said.

Although Bartlett said DEP is moving forward as planned, Clean Water Network's Linda Young said her group has warned it will sue if DEP delays action again.

"(The federal) EPA has to make sure the criteria adopted are protective of human health when those fish are consumed," said Young, the group's director.

After the hearings from May 15-17, DEP hopes to adopt updated rules by the end of the year, Bartlett said.

The department also is proposing limits for nitrogen and phosphorus in estuaries along the Florida Panhandle. And the department will consider setting new requirements for dissolved oxygen, which affects the amount of pollution that can be discharged into waterways.

Florida's dissolved oxygen criteria were based on national criteria from studies conducted in the 1960s and 1970s, Bartlett said.

He said in more recent years, DEP has invested in a "huge" monitoring system in Florida to determine what dissolved oxygen conditions exist naturally in Florida. That science also will be presented at the workshops.

The Conservancy of Southwest Florida is tracking the dissolved oxygen issue and has raised serious concerns with DEP, said Jennifer Hecker, the group's director of natural resource policy.

"Sometimes by changing the goal and standard you can create compliance," Hecker said. "It doesn't necessarily make anything better -- that is the concern. We want to see things truly improve. I think that is what Floridians want as well."

Young warned that industry groups are seeking to allow pollution to continue by reducing dissolved oxygen -- along with setting weak nitrogen and phosphorus limits and creating new designated uses for waterways with their own pollution limits.

Bartlett responded the science behind dissolved oxygen standard needs to be updated based on new science, just like with the nitrogen and phosphorus limits. And he said DEP will looking for feedback from the public at its upcoming workshops.

"We can't really do anything at DEP that is not truly and soundly rooted in the science," Bartlett said. "There is no other way to do it really."

Almost two decades after the EPA imposed the biggest fine at the time on the county for ignoring the Clean Water Act, the feds are back and talking to Miami-Dade leaders, this time about repairing miles of faulty pipes that carry raw sewage.

Miami-Dade County’s 7,500 miles of sewage lines are in such decrepit shape and rupture so frequently — sometimes spilling raw waste into waterways and Biscayne Bay — that federal environmental regulators are demanding repairs and upgrades that could cost upwards of a billion dollars.

Authorities from the U.S. Environmental Protection Agency, the Department of Justice and Florida Department of Environmental Protection met Wednesday morning with leaders at County Hall to begin what figures to be a lengthy and expensive negotiation for Miami-Dade.

John Renfrow, director of Miami-Dade’s Water and Sewer Department, acknowledged the string of major ruptures that have plagued the county’s sewage system in recent years, saying the aging network is “being held together by chewing gum.” He added he has sought more money to fix the leaks for a long time.

The price tag, though still uncertain, will easily reach the hundreds of millions and could top $1 billion based on past repair projects. The massive overhaul almost certainly will mean rate hikes for hundreds of thousands of residents who have historically paid some of the lowest fees in the state.

“We would like to think there’s state and federal assistance,” said Doug Yoder, Water and Sewer deputy director for regional compliance. “But this is ultimately going to come back to rates. It will require our rates go up, either to generate cash or to pay bonds back.”

The federal complaints are sketched out in a 78-page draft consent decree claiming Miami-Dade County has violated sections of the Clean Water Act, along with terms and conditions of its National Pollutant Discharge Elimination System permits. The report doesn’t detail specific failures, but said state and federal environmental protection agencies “have inspected Miami-Dade’s WCTS [wastewater collection treatment system] and WWTPs [wastewater treatment plants] and have discovered a number of improper management, operations, and maintenance practices.”

Miami-Dade has suffered at least three major sewer pipe breaks the past three years, and a recent internal report shows that three sections of 54-inch pipe under the bay, leading to the Virginia Key water treatment plant, are so brittle they could rupture at any time. Renfrow told The Miami Herald earlier this year that a break in that pipe, which carries 25 million gallons of raw sewage each day from Surfside, Miami Beach, and Bal Harbour, could be “catastrophic.”

He said it would mean “you’d have to close down the beaches and it would be an environmental mess.”

Aging sewer lines are not a problem unique to Miami-Dade. The EPA estimates there are 240,000 line breaks across the country each year as governments struggle to find revenue to repair sewage systems that in some cases are 100 years old. Fixing the nation’s sewer line ills could exceed $100 billion, the EPA noted.

Though the EPA wouldn’t comment directly on the complaint, the agency seems to be focusing on the Virginia Key line and several other pipe lines that have broken the past few years. The county’s system, built in the 1920s, last underwent major repairs in the 1970s.

The last time Miami-Dade was hit with a consent decree in 1996, it paid a $2 million fine, at the time the largest penalty paid to the EPA for Clean Water Act violations. Unlike the current decree, which is looking at old faulty pipes, the previous probe focused on the county’s lack of capacity to drain water overflows. In the 1990s, overflows and spills into the Miami River, Biscayne Bay and canals were mostly due to the system’s inability to handle big rainstorms.

Since then, the county has spent nearly $2 billion upgrading its system, from a $600 million overhaul of the water treatment facility in South Dade, to repairing more than 500 pump stations, to retrofitting thousands of homes with low-flush toilets. Water flow has been reduced by about 12 percent, or close to 100 million gallons a day.

Yet, the federal government maintains, Miami-Dade must spend billions more because over the past decade miles of aging pipeline crisscrossing the county are breaking with increasing frequency.

“The system is getting old,” said Bertha Goldenberg, the water and sewer department’s assistant director.

Adding to the worries, engineers have linked many of the worst breaks to defective pipe built by Interpace, a now-defunct company whose products were widely used in the 1970s. Now, some are failing decades earlier than expected. Over time, steel reinforcement wires inside the concrete pipes have corroded, broken and failed.

Recent breakdowns have occurred in Hialeah — where a 54-inch main break left a giant sinkhole — in Northwest Dade, where a 72-inch pipe burst and leaked almost 20 million gallons of sewage into a canal leading to Biscayne Bay, and in Miami Lakes, where a bus got stuck in a sinkhole after a 12-inch pipe broke. Fixing the system can be taxing, as groups of workers head out at night to one of the county’s 1,041 pump stations, then insert machines with mini cameras to run through the pipes in search of cracks or tears.

Perhaps the most infamous sewage rupture in recent memory occurred in 2000, when the line from Government Cut to Virginia Key was accidentally ruptured when contractors installing new boatlifts at Miami Beach Marina drilled through it. The resulting gusher of raw sewage cost $2.5 million to repair and the stinking slick closed surrounding waters for days.

 

The Everglades, our life-sustaining River of Grass, needs every friend it can get. And it’s getting a real whopper of an advocate in Erik Eikenberg, who was named chief executive of the Everglades Foundation this week.

The Foundation is a politically influential, well-funded organization committed to Everglades restoration. Its board found Mr. Eikenberg to be the perfect fit for the lead position. His background backs up that thinking: Now a Tallahassee lobbyist, Mr. Eikenberg is a politically astute former chief aide to Gov. Charlie Crist. He’s well-connected in both Tallahassee and Washington and championed the 2008 Everglades-restoration land deal that Mr. Crist advocated with the U.S. Sugar Corp. Years before, he was chief of staff in to U.S. Rep. E. Clay Shaw, a Fort Lauderdale Republican who was a strong supporter of the landmark $12.4 billion Everglades restoration plan. And how’s this for serendipity? Mr. Eikenberg, a native of Coral Springs, is a graduate of Marjory Stoneman Douglas High School.

The Everglades warrants every bit of political muscle Mr. Eikenberg can flex. It is not only an essential ecosystem, delivering water to South Florida from Lake Okeechobee. In just the past three years, restoration projects have created more than 10,000 jobs — and that was in the midst of a recession. Yet hundreds of thousands of jobs depend on the water system. A healthy Everglades spurs recreational tourism, another moneymaker for the state.

Despite this vital role that the Everglades plays in our lives, it has, over too many years, been abused by polluted runoff from farming areas and homes, gouged by development and, of course, had its funds drained to help balance the state budget. Last year, Gov. Scott and the Legislature decimated funds for Everglades restoration projects. Short-sighted, to say the least. This year, $30 million was restored for projects.

Everglades restoration needs sustained and consistent funding.

In Mr. Eikenberg, the River of Grass appears to have a sustained and consistent voice advocating for its good health.

The deal struck by Miami-Dade County and state and federal agencies with environmentalists to proceed with the “Deep Dredge” project — instrumental for PortMiami’s growth and this area’s economic future — is a victory for Biscayne Bay’s sea life and every resident and visitor to our area.

It allows the port to keep to the dredge schedule so that it will be ready by 2014 to receive new super-sized cargo ships coming through the Panama Canal that need 50-feet deep waters to dock in Miami. How the agreement was reached was not ideal, however.

Environmentalists’ appeals were rushed within a 30-day deadline imposed by Tallahassee legislators and supported by county officials. Tropical Audobon Society, commercial fishermen and other groups concerned that the drilling blasts would destroy coral, kill sea life and muck up the bay’s pristine turquoise waters agreed to drop an administrative challenge if the county provided $2.3 million more than previously budgeted for restoration and monitoring projects that will save or restore corals, sea grass beds and other sealife.

As Laura Reynolds, executive director of the Tropical Audubon Society, noted, the deal “raised the bar” for environmental protection.

The Army Corps of Engineers, meanwhile, has experience in the bay, having successfully dredged there before. That bodes well for Biscayne Bay’s marine life, including turtles, dolphin and snook as the agreement limits the time frame of the blasts to better protect fish during times of day (dawn and dusk) when they become more active. It also bans blasting along the northern jetty of Government Cut during snook spawning season.

About eight acres of sea grass beds and seven acres of reefs (most at the entrance of the channel) will be lost to the dredge, which includes widening the port’s offshore entrance to the main channel by some 300 feet and deepening the port to 50 or 52 feet from the current 42 feet of depth.

Under the settlement reached during mediation with the state Department of Environmental Protection, the county and the Corps, two more acres of new sea grass areas will be added for mitigation, resulting in 16.6 acres. Small corals would also be moved to a new artificial reef or brought to other natural ones in the bay not affected by the blasting. Also, money will be spent to restore coastal dunes on north Virginia Key and two mangrove and wetlands projects at Oleta River State Park in North Miami.

The Miami-Dade County Commission likely will approve the settlement next week. But that still leaves one big environmental issue unresolved: an old and potentially defective sewer pipe that runs under the shipping channel and must be replaced. It carries 25 million gallons of raw sewage a day from Bal Harbour, Miami Beach and other beach towns to the county sewage treatment plant on Virginia Key.

The county is working on a fix, which will require burying a new pipe deep enough to be safe from the blasting for the dredge. There is no room for error. Residents and beach-goers’ health and safety are at stake.

With the deeper port, thousands of new good-paying jobs will result, combined with a new rail system that will move cargo directly from the port, saving time and local roadways from heavy truck traffic. Port Director Bill Johnson says the deeper channel could double the port’s container shipping business. That’s why reaching an agreement was so important to South Florida’s future.
