Researchers from the U.S. Department of Agriculture have created a searchable atlas that compiles regional research and efforts to deal with water scarcity and drought.
The map, called the Water Adaptation Techniques Atlas, was developed by the agency’s Southwest and California Climate Hubs and so far contains 183 case studies from Arizona, California, New Mexico, Nevada and Utah.
It was the end of a fight that lasted for almost a decade. On 12 May 2022, the California Coastal Commission, which has a legal mandate to protect the coastline of the US state, voted to deny the building permit for a large seawater-desalination plant that was proposed to be erected near Huntington Beach. Ever since the application to build the plant was made in 2013, this mega-project has been dividing experts, politicians and activists.
The East County Advanced Water Purification Program broke ground, marking an important milestone for the project, East San Diego County, the region and the entire water industry.
Program representatives, elected officials and water industry leaders gathered at the future site of the treatment facility in Santee to celebrate the Program that will create a new, local, sustainable and drought-proof drinking water supply using state-of-the-art technology to purify East San Diego County’s recycled water.
Construction work is underway in several areas of San Diego, building major infrastructure projects for Phase 1 of Pure Water San Diego.
Phase 1 of Pure Water San Diego, including pipelines, pump stations, and treatment facilities, has started in Morena, Bay Park, Clairemont, University City, Miramar, and Scripps Ranch communities. It is a milestone toward the realization of securing a local, drought-resilient water supply for San Diegans for generations to come.
Pure Water is the City of San Diego’s largest-ever infrastructure program that will provide nearly half of San Diego’s water supply by 2035. Pure Water will use purification technology to clean recycled wastewater and is a cost-effective investment for San Diego’s water supply needs.
Residents, businesses, and commuters may be impacted by road closures, detours, and construction noise during construction. Construction for this project will primarily take place on weeknights from 7 p.m. to 5 a.m., except on Nobel Drive, when construction will take place on weekdays from 8:30 a.m. to 3:30 p.m. Tunneling work will be done around the clock with adherence to noise requirements.

Upon its completion, Pure Water San Diego will contribute 30 million gallons per day of high-quality purified water, reducing the City’s dependence on imported water.
The Morena Northern Pipelines and Tunnels project now underway will connect to the Morena Pipelines Middle Alignment to the south and the North City Water Reclamation Plant to the north.
This project includes portions of two 10.5-mile pipelines: one 48-inch wastewater pipeline, which will carry wastewater north to the North City facilities for purification, and one 30-inch brine line that will carry the byproduct from water purification south to the Point Loma Wastewater Treatment Plant.
This project begins on Genesee Avenue and Appleton Street and continues on Genesee Avenue, Nobel Drive, Towne Centre Drive, and Executive Drive. Tunneling will be completed at Genesee Avenue and State Route 52 (San Clemente Creek), at Genesee Avenue and Rose Creek Canyon, and under Interstate 805.

Currently, the City of San Diego depends primarily on a reliable imported water supply to deliver clean and safe drinking water to its communities. The investment in advanced water purification with the construction of Pure Water San Diego will help secure a high-quality, safe, local, and drought-proof water supply for the future. Phase 1 is scheduled to be completed and commence operation in 2024. Pure Water San Diego will eventually provide nearly half of San Diego’s water supply locally by 2035 with the completion of Phase 2.
Purified water produced at the completed plant will be delivered to the Miramar Reservoir, blended with the City of San Diego’s imported and local water sources, and treated again at the existing Miramar Water Treatment Plant. After this process, the water will be distributed to customers.

(Editor’s Note: The City of San Diego is one of the San Diego County Water Authority’s 24 member agencies that deliver water across the metropolitan San Diego region.)
The Orange County Water District has been awarded a $3.6 million grant from the California Department of Water Resources Integrated Regional Water Management (IRWM) grant program for use toward the construction of its Groundwater Replenishment System Final Expansion project. Operational since 2008, the GWRS is undergoing its second and final expansion.
