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.

In 2014 Santa Monica embarked on a course to be virtually water independent through local sources by 2023. … The switch has been accomplished through an extensive plan that encompasses small measures like toilet replacements, household rain harvest barrels and aggressive conservation to large measures like cleaning up contaminated groundwater, capturing street runoff and recycling water.

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.

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.

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.
