Exotic Animals Cause a Stir at the Marsh
The headline 25 years ago was terrifying: A hissing “marsh monster” — lurching, biting, and finally ripping through a makeshift trap with its bear-like 2 ½-inch claws — was discovered at IRWD’s San Joaquin Marsh and Wildlife Sanctuary.
Biologists at the time told the Irvine World News it was a snapping turtle, probably between 10 and 50 years old. The bad-tempered beast was captured and transported to a rescue organization for safe keeping.
Snapping turtles are illegal to own in California, but many people get them anyway when they are small, and release them into the “wilds” of suburbia once they get big — and aggressive.
But it’s not just turtles. A whole host of creatures are living at the marsh. They either found their own way or were brought there by a neighbor.
Wetlands Scientist Mo Wise said she once saw a goldfish swimming in one of the ponds. It was the size of a baseball.
“The marsh is chock full of surprises,” she said.
Other wild and/or non-native animals found there include rabbits, coyotes, raccoons, crayfish, woodrats, exotic birds, many varieties of turtles (including the snapping variety), and fish.
“There are 15 species of fish at the marsh,” said Natural Resources Manager Ian Swift. “None of them is native.”
Apart from the goldfish, Swift and Wise have spotted catfish, bass, red shiners and other species that were either planted there or found their way from upstream.
The fish provide food for the birds at the marsh, as well as the turtles. Despite most of these species being invasive, a healthy balance of life is going on, Swift said.
“There’s this huge food chain that exists at the marsh that wouldn’t be there naturally,” he said. “So far, there’s an equilibrium, where it doesn’t look like there are too many impacts.”
Some of these species are brought in by humans: pet fish and turtles that have outgrown their homes, stray rodents, even a few kittens.
Releasing these orphaned pets and pests is not good — for the animals or the marsh.
Rodents brought in might have ingested poison, which can harm the native birds when eaten as prey. Rabbits nibble away at the native grasses before they can take root. And the turtle population — while currently in balance — can easily get out of hand.
IRWD monitors and records the animals spotted at the marsh for research. It’s another way to keep track of the ecological balance of the wildlife sanctuary, and it helps to identify new changes and trends.
Swift described his occasional encounters with a bobcat mother and her cubs some years ago — walking down the paths between the various ponds. They are still seen from time to time throughout the natural areas of Irvine, but they haven’t visited the marsh since 2015.
“I miss seeing them,” he said, “but at least we know they’re OK.”
If you find yourself with an unwanted pet or animal, please don’t release it at the marsh. Contact your local animal shelter to arrange for a safe surrender.
IRWD Receives Prestigious Utility of the Future Designation
Irvine Ranch Water District has been recognized by water professionals and organizations around the nation as a Utility of the Future Today — a formal designation given to agencies that have demonstrated forward-thinking, innovative approaches to trends in the industry today.
This is IRWD’s first UoTF award, granted in recognition of the District’s recycled water programs and infrastructure. Judging for the award is done by members of a selection committee consisting of peer utility general managers and executives.
The District is a national leader in water reuse — with a history of achievements dating to 1963, when our Board of Directors implemented a vision to integrate water recycling into the design of the surrounding community. IRWD’s highly skilled staff using state-of-the-art technologies and processes mean IRWD’s recycled water consistently meets the California Water Resources Control Board’s stringent water quality criteria for water reuse.
Today, nearly all of the public and commercial irrigated landscape in our service area — including parks, medians, golf courses and community association property — is irrigated with recycled water. It is also used for toilet and urinal flushing in commercial buildings, for cooling towers, construction activities such as dust control, grading and compaction, and industrial processes such as concrete production and composting. IRWD delivers about 28 million gallons of recycled water daily to more than 6,200 metered customer connections.
“We are extremely proud to have received this honor,” General Manager Paul Cook said. “This is one of the highest distinctions in the industry, carrying the added significance of being judged by peers.”
This year’s award was announced at the Water Environment Federation’s Technical Exhibition and Conference on Oct. 9.
The award is sponsored by the National Association of Clean Water Agencies, Water Environment Federation, Water Research Foundation, and WateReuse, with support from the United States Environmental Protection Agency.
New Sprinkler Law Hits Shelves to Save Water and Money
Too much pressure is a bad thing – for us, our garden sprinklers, and ultimately for California’s water supply.
Most spray head sprinklers are set for about 30 pounds per square inch. But the water flowing into the system is frequently higher – causing them to mist and overspray, which wastes significant amounts water.
That’s why California this month began requiring that all irrigation spray sprinkler bodies sold in stores be pressure-regulated for better efficiency.
The new spray bodies cost a few dollars more, but they can be up to 40% more efficient, depending on the age of the sprinklers they are replacing.
With about half of all the state’s drinking water used for irrigation, that adds up to a lot of savings.
By 2030 – once most homes have installed the new devices – California expects a statewide savings of 152 billion gallons of water a year. That’s more water than it takes to serve the entire city of San Diego. Water efficiency translates to savings on your water bill.
There is no requirement to rush out and replace your spray head sprinklers all at once. The new regulation anticipates that much of the transformation will happen over time as individual units get replaced. (Sprinklers last an average of 10 years.)
When purchasing these spray bodies, be sure they are marked with the WaterSense logo. For more information, visit epa.gov/watersense/spray-sprinkler-bodies.
IRWD Showcases Essential Staff During Water Professionals Appreciation Week
As part of California’s fourth annual Water Professionals Appreciation Week, Irvine Ranch Water District is pleased to celebrate the people who provide safe, plentiful water and reliable sewer service.
“Water Professionals Appreciation Week is a great time to say thank you to IRWD’s talented and dedicated employees,” General Manager Paul Cook said. “Now more than ever, as we work through the pandemic, we provide a truly essential service for our community.”
Recent labor studies estimate California’s water industry employs 60,000 people and needs about 6,000 new employees each year due to turnover. The industry offers a wide variety of rewarding career opportunities in engineering, biology, finance, business administration, law, communications and more.
Water Professionals Appreciation Week — Oct. 3–11 this year — was established by the state Senate in 2017. The measure was sponsored by a coalition of water associations led by the Association of California Water Agencies, WateReuse California, California Municipal Utilities Association, California Association of Sanitation Agencies, and California Water Association. The annually designated week begins on the first Saturday of October and ends on Sunday of the following weekend.
Add-On Devices Have No Place in Your Meter Box
Smart technology offers several new add-on devices that can monitor and send you real-time alerts about your water use. Some will shut off the water to your home if a leak is detected.
If you are looking into getting one of these devices, take heed: IRWD does not permit the type affixed to the water meter. If we find one, or any other unauthorized equipment inside the meter box, we will remove it.
Why? IRWD owns the water meter, the meter box and everything inside it. We prohibit tampering of any kind within the box because we need to ensure unimpeded access to the meter as a part of our ongoing operations.
Section 12.4 of the District’s Rules and Regulations states, “Customer owned smart metering equipment installed on District meters is prohibited as set forth in section 4.7 of these Rules and Regulations.” Furthermore, section 4.71 states, “Installation by anyone other than the District of any equipment installed in a District facility, including a meter box or pressure regulating valve (PRV) vault onto any meter or PRV, is ‘tampering.’ This includes but is not limited to leak detection equipment, flow sensors, batteries or antennas. If any unpermitted equipment is installed it will be removed by District staff.”
What type of flow monitoring device should you consider?
If you are thinking about investing in a home water monitoring system, limit yourself to those installed between your property line and your home.
Some attach to the outside of the pipe, and others are installed in-line with the pipe so the water flows through them.
The real-time information provided by this technology can benefit customers because it tracks water use and encourages efficiency.
And, when it comes to preventing flooding in your home, devices with the water shutoff function provide added security that could save you from the grief of costly water damage repairs.
