Frequently Asked Questions
The Monterey Regional Water Pollution Control Agency (MRWPCA), like many other agencies in California, is studying ways to fully reuse its wastewater. Under the planned scenario, treated wastewater will be further purified using advanced treatment processes. This water would then percolate or filter through the soil naturally into the aquifer, just like rainwater. This process "recharges" or helps replenish the aquifer while safeguarding it from seawater intrusion.
In California (as well as other parts of the country and the world) water supplies are being stretched to the limit. The Monterey region is dealing with an adjudicated water basin and limited water supplies, stricter environmental constraints, and periodic droughts that will curtail unlimited use of our water supplies. Conserving and reusing this water resource instead of disposing of it in the ocean is efficient and provides a long term, sustainable water supply for our communities.
A groundwater replenishment system would create a reliable, locally produced, ultra-pure water supply. In addition, this strictly regulated water supply would allow us to limit wastewater discharge into the delicate Monterey Bay Marine Sanctuary.
Groundwater replenishment is used in many places around the world. As an example, Orange County California has operated a groundwater replenishment project since 1971. In this case, highly treated recycled water is used to prevent seawater intrusion into its aquifer by recharging it. Other communities include Los Angeles; Inland Empire; Las Vegas, Nevada; Scottsdale, Arizona; and El Paso, Texas.
The California Department of Health Services is charged with the responsibility for establishing uniform statewide reclamation criteria to ensure that the use of groundwater replenishment will not be detrimental to public health.
MRWPCA would take treated wastewater and put it through an additional three-step treatment process of microfiltration, reverse osmosis, and oxidation with ultraviolet light and hydrogen peroxide. This process will make the water near distilled quality and exceeds all drinking water standards.
The GWR Project creates ultra-pure water. By adding this water into the groundwater it will, over time, increase the quality of the water.
