Drought resistant garden graces roof of recycled water reservoir in Walnut Valley Water District
You can’t drink it and you can’t bathe in it, but recycled water is a vital part of the solution to our ongoing drought.
Walnut Valley and Rowland Water Districts are adding it to their arsenal as they strive to ensure water service at reasonable rates.
“More than 60 percent of our customers’ water usage is outside the home,” explained Mike Holmes, Walnut’s general manager. “Most of that is used for landscaping, and you don’t need potable water for that.”
So the two local water districts have banded together to build recycled water systems to serve large commercial users such as golf courses and cemeteries. It is also used in our city and county parks.
Walnut water officials say they deliver 537 million gallons of this “drought-proof” water every year. That’s a half-billion gallons of water that don’t have to be imported from Northern California.
The two water districts receive recycled water from the County Sanitation Districts’ Pomona Water Reclamation Plant. Recycled water is the name given wastewater that has been treated extensively. After being tested and certified by the Department of Health Services, the recycled water is safe for irrigation purposes.
One of Walnut’s last projects was a new 1 million gallon reservoir for recycled water at the district’s Parker Canyon facility. Even the roof of the semi-submerged reservoir was recycled, holding a garden that helps it blend into the Puente Hills.
And the Rowland Water District installed a new recycled water line along Fullerton Road, running from Industry under the 60 Freeway to the Queen of Heaven cemetery.
“In addition to buying water from the La Habra Heights Water District, recycled water will help us guarantee service to our customers at a reasonable rate,” said Rowland’s General Manager Ken Deck.
