The Water Replenishment District
manages groundwater for nearly
four million residents in 43 cities of Southern
Los Angeles County and is the official
Groundwater Level Monitoring
for the Central Basin and West Coast Basin.
The 420 square mile service area uses about 250,000
acre-feet of groundwater per year taken from the
aquifers of the Central Coast and West Coast Basins.
This equates to nearly 40% of the total demand for water.
WRD is involved in groundwater monitoring, safe drinking
water programs, combating seawater intrusion and
groundwater replenishment operations throughout
Southern Los Angeles County.
Service Area Map
WRD has been monitoring the Central Basin and West Coast Basin for over 50 years, and this year's annual report presents the most comprehensive information to date as a result of WRD's growing network of aquifer-specific monitoring wells and in-depth water quality analysis. The Regional Groundwater Monitoring Program currently consists of a network of nearly 300 monitoring wells at over 50 locations throughout the District.
This Regional Groundwater Monitoring Report presents information on groundwater levels and groundwater quality for the previous water year which runs from October 1 through September 30 of each year. This current report is for water year 2013-14. Download Report >>

WRD is expanding the production capacity of the Leo J. Vander Lans Advanced Water Treatment Faciliy to replace the use of imported water in South Los Angeles County. WRD currently receives tertiary treated recycled water from the adjacent Los Angeles County Sanitation District’s Long Beach Water Reclamation Plant. In order to ensure a sufficient supply of source water to meet the expansion requirements of the Vander Lans Facity, WRD will also use tertiary effluent from LACSD’s Los Coyotes Water Reclamation Plant in the future.
This amended Engineering Report for the Vander Lans Facility presents the overview and technical details involved in implementing the design of these new facilities.
The Water Independence Now (WIN) program is a series of projects that will fully utilize stormwater and recycled water sources to restore and protect the groundwater resources of the Central and West Coast Basins. In the past, a large percentage of replenishment water came from sources in Northern California and the Colorado River.
WIN seeks to completely eliminate this dependence on imported water to ensure the future security of our region by developing local resources to create a locally sustainable groundwater supply.. >>
The Water Replenishment District has been awarded the prestigious Government Finance Officers Association (GFOA) Certificate of Achievement for Excellence in Financial Reporting for outstanding budget presentation and process for nine years in a row.

Safe Drinking Water Project
WRD's Safe Drinking water Program offers assistance to pumpers for treating contaminated groundwater. This allows affected wells to meet public drinking water standards and lessens the probability of contaminated water affecting other wells.
