Gray water, also spelled as grey water, is water that already has been used domestically, commercially and industrially. This includes the leftover, untreated water generated from clothes washers, bathtubs and bathroom sinks.
Too often, entrenched conflicts that pit water user against water user block efforts to secure a sustainable, equitable, and democratic water future in California. Striking a balance involves art and science, compassion and flexibility, and adherence to science and the law. Felicia Marcus is a public servant unknown to many Californians. But as she concludes her tenure as chair of the State Water Resources Control Board, we owe her a debt of gratitude for consistently reaching for that balance.
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.
The sewer rate increases approved for Morro Bay will go into effect in July, despite opposition from a group that earlier claimed it got enough protest signatures to stop the rate hike. Morro Bay City Manager Scott Collins clarified in a recent report that the protest was unsuccessful and the measure will go into effect with customers seeing the additional charge on their August bill.
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.
Droughts and floods have always tested water management, driven water systems improvements, and helped water organizations and users maintain focus and discipline. California’s 2012-2016 drought and the very wet 2017 water year were such tests.
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.
Far less settled is how Newsom will fill his administration’s most important positions regarding state water policy. One of Newsom’s key tests confronts him immediate: State Water Resources Control Board Chair Felicia Marcus’ term expires this week.
The Governor’s Office of Planning and Research has spent five years drafting a comprehensive update to 30 sections of the California Environmental Quality Act (CEQA) guidelines. Several changes to the Guidelines address two hot button topics: global climate change and statewide affordable housing shortages. Many of the changes will significantly alter the application of CEQA to future projects.
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.
Montgomery is known for fostering collaborative relationships among stakeholders and as a leader in protecting and restoring water quality within California and throughout the Southwest and the Pacific Islands. He is currently serving as the Assistant Director of the Water Division in the US Environmental Protection Agency (Region 9).
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.
San Franciscans who want to conserve water by irrigating their yards with the runoff from their showers and bathroom sinks will no longer have to get a $250 permit or inspection from the city, under legislation introduced Tuesday by Supervisor Scott Wiener.
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.
Ralph Petroff is changing the way California homes use water. As executive chairman of Nexus eWater, Petroff last week unveiled the first housing subdivision in the United States with on-site water recycling standard in every home.
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.
This is a follow-up post to the “One drop, a dozen options” article in the Summer 2015 Mono Lake Newsletter. The article mentions longtime Mono Lake Committee member Regina Hirsch and her business Sierra Watershed Progressive with respect to the greywater system she helped us create in 2012.
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?
In Southern California, gardens are going grey. Grey water systems that take spent water from showers, bathroom faucets and washers and use it to quench the landscape are seen by some as the next step in sustainable gardening across bone-dry Southern California.
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.
This 25-minute documentary-style DVD, developed in partnership with the California Department of Water Resources, provides an excellent overview of climate change and how it is already affecting California. The DVD also explains what scientists anticipate in the future related to sea level rise and precipitation/runoff changes and explores the efforts that are underway to plan and adapt to climate.
In the West, it is not a matter of if a drought will occur, but when. In an effort to develop a drought-proof water supply, many communities are turning to water recycling. Water recycling is reusing treated wastewater for irrigating golf courses, other urban landscapes, some crops, wetlands enhancement, industrial processes and even groundwater recharge. But many people do not understand how water is treated, recycled and reused, causing some to oppose new projects.
As the state’s population continues to grow and traditional water supplies grow tighter, there is increased interest in reusing treated wastewater for a variety of activities, including irrigation of crops, parks and golf courses, groundwater recharge and industrial uses.
The 28-page Layperson’s Guide to California Wastewater is an in-depth, easy-to-understand publication that provides background information on the history of wastewater treatment and how wastewater is collected, conveyed, treated and disposed of today. The guide also offers case studies of different treatment plants and their treatment processes.
Gray water, also spelled as grey water, is water that already has been used domestically, commercially and industrially. This includes the leftover, untreated water generated from clothes washers, bathtubs and bathroom sinks.
This water source is a common way to recycle water and stretch urban water supplies. As part of this, gray water ‘harvesting’ (the collecting of gray water from sinks, showers, etc.) is increasingly popular, especially as a way to flush toilets.
