The Water Conservation Garden will run out of money as early as mid-December, the nonprofit organization Friends of The Water Conservation Garden stated at an October 24 meeting of the Water Conservation Garden Joint Powers Authority, the consortium of public utility and governmental entities that oversees the Friends.
After an Orange County resident flushes her toilet, the water flows through the Southern California community’s sewer system, meanders its way to the sanitation plant, has its solids removed, is piped to a wastewater recycling facility next door and undergoes three different purification processes until it is clean enough to drink.
After more than two decades of drought, water utilities serving the largest urban regions in the arid Southwest are embracing a drought-proof source of drinking water long considered a supply of last resort: purified sewage.
Water supplies have tightened to the point that Phoenix and the water supplier for 19 million Southern California residents are racing to adopt an expensive technology called “direct potable reuse” or “advanced purification” to reduce their reliance on imported water from the dwindling Colorado River.
“[Utilities] see that the river is overallocated, and they see that the climate is changing,” said Kathryn Sorensen, former director of Phoenix Water Services Department. “They’re looking at this and understanding that the river supply is highly variable and extremely uncertain in the future.”
The Colorado River that sustains nearly 40 million people and more than 4 million acres of cropland across seven states is shrinking because of climate change and overuse. The river’s flows have declined approximately 20 percent over the past century, and a more than two-decade drought that began at the turn of this century has pushed the system to its limits.
With so much at stake, cities dependent on the river are strengthening water conservation measures and pursuing new sources of water with urgency.
WATER PRICE LINE RISING: Who could forget last May, when Arizona, California and Nevada made a three-year pact to conserve water from the Colorado River? Many thought it couldn’t be done, but with Lake Mead reservoir levels at a historic low, and the federal government poised to wrest control of the process, the states agreed to conserve 10 percent of their water — nearly a billion gallons — between now and 2026.
In a pivotal move addressing California’s water conservation goals and reinforcing partnerships in the face of the ongoing Colorado River drought, the Metropolitan Water District is seeking authorization for its General Manager to establish agreements with the Coachella Valley Water District, Imperial Irrigation District, and San Diego County Water Authority. These agreements aim to facilitate the addition of water to Lake Mead under the U.S. Bureau of Reclamation’s Lower Colorado River Basin System Conservation and Efficiency Program for the year 2023.
Arizona’s future was at a critical juncture at the beginning of 2023.
Massive cuts to the state’s Colorado River water supply were being imposed. Deadlines loomed from the federal government for the seven states that rely on Colorado River water to come up with a solution for how to cut use even further as the nation’s two largest reservoirs recorded among their lowest levels ever after decades of drought caused by overconsumption and climate change.
It’s still more than seven weeks before the official start of winter (Dec. 21), but weekend storms in Colorado’s high country are reason enough to look in on snowpack levels that will eventually provide the water that flows to Lake Mead.
A month into the 2023 “water year,” snowpack levels are slightly above normal in the Upper Colorado River Basin: 114% as of Nov. 1, according to data on the U.S. Bureau of Reclamation’s website. The water year runs from Oct. 1 to Sept. 30 each year.
With climatologists predicting the potential for above-average precipitation in the months ahead due to the El Niño weather phenomenon, it’s an ideal time to take advantage of the County of San Diego’s upcoming rainwater harvesting workshops and rain barrel rebates.
The County’s Waterscape Rebate Program will host free rainwater harvesting workshops in Fall and Winter 2023.

The County’s Waterscape Rebate Program will host free rainwater harvesting workshops in Fall and Winter 2023. Workshops help residents learn how to capture rainwater to supplement their irrigation needs, save money on water bills, and protect our region’s environment by preventing pollutants from spilling into regional watersheds.

The next scheduled workshop is Wednesday, November 8, at 1 p.m. at Tractor Supply, 27444 Valley Center Road. Future workshops will be listed on the County of San Diego Waterscape Rebate Program website.
At the end of the workshop, residents who live in unincorporated areas of San Diego County may be eligible to receive a free rain barrel. Participants in incorporated areas can check their rebate eligibility on the San Diego County website’s interactive map.
The County of San Diego Watershed Protection Program (WPP) partners with the San Diego County Water Authority and Metropolitan Water District of Southern California (through SoCal WaterSmart) and can assist residents in determining which program benefits are available.
During San Diego County’s limited periods of rainfall, any rainwater captured from your roof and property saves money. It also helps the region maintain its water supplies.

Workshops introduce residents to several beautiful, efficient ways to save rainwater. In addition to rain barrels, directing downspouts to fill containers lets you choose how to use the rainwater you capture. The overflow should empty onto your yard or a landscape feature to infiltrate the excess flow into the soil. Rain chains can assist with this.
The Countyl of San Diego is committed to protecting the water quality in county creeks, streams, and coastal areas. Runoff from irrigation, storms, and even faulty septic systems can bring pollutants to county waterways and threaten public health.
When businesses and households make changes to reduce water use and use rainwater in their landscapes, it helps preserve healthy, safe waterways and more reliable water supplies.
After buying rain-saving containers or other items eligible for rebates, and have installed them, residents can apply for rebates. Current rain barrel rebates are $35 and are limited to two per household for most San Diego County residents. Multiple projects are eligible. Details at: Socal WaterSmart.

Whether or not El Niño results in increased rainfall, even light rain can provide enough water for later use. A roof with a 2,000-square-foot surface area can capture 300 gallons from only a quarter inch of rain.
Stored water can be released gradually into landscaping between winter rainstorms, building up the soil sponge and ensuring that native plants get adequate water during the winter months when they need it most. If additional water is needed in the summer, captured and stored water during the winter could be used as supplemental irrigation.
The Solana Center For Environmental Innovation website has additional information on rain barrels and rebate programs.
The Biden-Harris administration October 25 announced next steps in the efforts to protect the stability and sustainability of the Colorado River System and strengthen water security in the West. The Department of the Interior’s Bureau of Reclamation released a revised draft Supplemental Environmental Impact Statement (SEIS) as part of the ongoing, collaborative effort to update the current interim operating guidelines for the near-term operation of Glen Canyon and Hoover Dams to address the ongoing drought and impacts from the climate crisis.
