Topic: Gray water

In a time when many people in the world are inside their houses to stop the spread of covid-19, it is easy to forget that good news still exists. The Environmental Protection Agency’s National Water Reuse Action Plan is a bit of good news. The Plan, announced on February 27, 2020, by EPA Administration Andrew Wheeler, prioritizes the use of recycled water.

Colorado was the last Western state to legalize greywater usage in 2013. Officials say that by 2050, our water supply could fall short for over one million people. … Colorado’s Water Plan wants to close the gap and recognizes greywater as one tool to help make that happen. However, not a single state-approved greywater system has been built since it was legalized.

Milpitas mayor Rich Tran is following up on a campaign promise to do something about the bad odor that has drifted over the city for decades. … The goal is to trace the source of the stench, which residents have long suspected to come from the Newby Island landfill, the San Jose-Santa Clara Regional Wastewater Facility or the Zanker-owned recycling facility.

The announcement by Mayor Eric Garcetti last month that Los Angeles will recycle all the wastewater produced at the Hyperion plant by 2035 signals an end to the era of addressing water shortages by importing water from far-flung places and initiates a long-anticipated era of reusing locally available supplies. The shift will require L.A. residents to understand both the necessity of the plan and the technology that will produce safe water.

NRDC is sponsoring legislation this year by Senator Hertzberg and Senator Wiener (SB 332, the Local Water Reliability Act) designed to help sustain water reliability and protect the environment. … The bill challenges water supply agencies and wastewater treatment plant operators to undertake a joint effort to plan and implement a conservation and discharge reduction strategy that reduces wasteful and polluting discharges to the ocean by 95% in 20 years.

Redlands’ wastewater treatment facility needs $40 million in upgrades soon thanks to years of deferred maintenance, officials say. But it could be worse – building a new facility would cost $100 million. The original plant was built in the 1960s, and the last major changes were made in 2004.

San Diego is in the midst of spending roughly $3 billion on a massive new water treatment system, but city officials can’t or won’t tell customers how that will affect their water bills. New water recycling plants will eventually purify enough sewage to provide a third of the city’s drinking water. In December, Voice of San Diego asked the city to estimate how much customers’ bills will increase because of the Pure Water project. The city, after weeks of delay, finally declined last week to offer any estimate because “there is no simple calculation” they could perform.

Technology already exists to treat reused water to levels meeting or exceeding health standards. But adequate technical capacity is not sufficient. Water reuse can trigger revulsion, especially when water is reused for drinking or other potable purposes. This note explores outreach and engagement strategies to overcome the “yuck factor” and achieve public support for water reuse.

California Gov. Gavin Newsom has named Jared Blumenfeld, a former Obama administration official and longtime environmental advocate as the new secretary of the California Environmental Protection Agency. Blumenfeld, 49, of San Francisco, will run the agency, known as Cal-EPA, which oversees a broad range of environmental and public health regulations statewide, on topics that include air pollution, water pollution, toxics regulation, pesticides and recycling. 

There’s every reason to expect that 2019 will be far better, largely because of Measure W, which was passed by voters in November. The initiative imposes a Los Angeles County parcel tax that will generate $300 million per year to reduce pollution from runoff and capture storm water to add to the water supply.

As water utilities and their customers increasingly look to gray water and runoff from storms to supplement their supply amid drought, more guidelines and research are needed to ensure that the water is safe, researchers said in a report released Wednesday.

The last rainfall in Riverside was a windfall for Michael Hickman, a retiree who has a home project underway to use rain gutters and barrels to collect some of the precipitation that lands on his roof.

Strands of silver hair fell into Annie Costanzo’s face as she wielded a sledgehammer against the brick walkway in her backyard. Plumes of dust and debris filled the air, and reddish-pink shards scattered in the wake of the 64-year-old sculptor’s latest water conservation project.

Not just during drought but even in times of normal precipitation, there is something absurd about taking precious drinking water — imported at great cost from environmentally fragile areas hundreds of miles away, pumped over the mountains using enormous amounts of energy, filtered, treated and tested so as to be safe for human consumption — and spraying it on lawns and flowers.

A Mill Valley home has been fitted with a series of pipes and valves to send shower, sink and clotheswasher graywater to landscaping in an effort to conserve limited supplies of fresh water from Mount Tamalpais and the Russian River used by Marin residents.

I like recycling. I like innovative solutions to California’s drought. … But while you’re hosing down those corn syrup barrels, why don’t you also put some thought to how you can phase out bottled water operations in California and other water-stressed areas?  

A demonstration house unveiled in El Dorado Hills last week by national builder KB Home recycles drain water for toilets and landscaping and can power itself entirely with solar panels. … Water recycling has been gaining momentum in California’s historic drought.
