Examples of Local Projects and New Technologies

 

Well
Well heads like the North Las Posas well head in Calleguas MWD are used to inject water into the ground for future storage in the conjunctive use program.
Desal Desal
Advanced membrane technology like these reverse osmosis filters are used to treat wastewater for beneficial use, resulting in near-distilled quality water at the Orange County Water District’s Groundwater Replenishment System.
Desal Rio Honda
Spreading Basins like the Rio Hondo desilting pond in Central Basin MWD are used to replenish our groundwater basins.
Spillway
The Lake Oroville Dam Spillway in Northern California, operated by the California Department of Water Resources, allows water to flow if the reservoir's maximum capacity is exceeded.
  Recycled Water
Recycled water, such as this one at Hemet in Eastern Municipal Water District, is a reliable supply alternative to potable water and is finding its ways into public parks and golf courses throughout the southland. Pink and purple signage informs passersby that irrigation water is not intended for drinking.
  Agricultural Irrigation
Recycled water release from Hill Canyon WTP in Thousand Oaks into Conejo Creek and capture by this diversion structure for agricultural irrigation. It is a part of a water exchange agreement between Calleguas MWD and United Water Conservation District in Ventura County for groundwater credit.
Smart Irrigation Controller
Metropolitan partnered with its member agencies to distribute nearly 7,000 “smart” irrigation controllers to the public through an exchange program where homeowners swapped their traditional controllers for weather-based models. The devices are expected to save 13,500 gallons each year over the estimated 10-year device life.
  Wastewater Treatment
A major wastewater treatment plant in Thousand Oaks, Tapia WTP supplies recycled water to Calleguas Municipal Water District and Las Virgenes Municipal Water District for municipal and agricultural irrigation.
  Recycled Water Storage
Recycled water storage tank at Nellie Gail Ranch, located in the Moulton Niguel Water District (a retail agency of Municipal Water District of Orange County), provides recycled water for landscape irrigation. MNWD supplies nearly 6,500 acre-feet of recycled water to its customers annually.
Desalter Plant
San Juan Basin Desalter recovers and treats brackish groundwater for potable use. The desalter, located in the Municipal Water District of Orange County service area, produces about 3,500 acre-feet of groundwater each year.
  California Friendly Home
Model homes, such as this Shea home in French Valley, retrofitted with California Friendly® landscape gives homeowners alternative choice to the traditional grass lawn.
