Big Bear Valley depends entirely on groundwater. In recent years, drought, warmer temperatures, and more variable rainfall have reduced how much water naturally refills the groundwater basin. This project would keep more water local by purifying it and putting it back into the ground for future use.

Local professionals have evaluated more than seven water supply and recharge options. Greenspot recharge provides the most cost-effective and reliable benefits of the evaluated alternatives. 

Greenspot is near existing Big Bear Lake Department of Water and Power and Big Bear City Community Services District wells. Utilizing this location for groundwater recharge reduces project costs by using existing groundwater wells to serve customers. 

Before it goes to Greenspot, water will be treated using a multi-step purification process including ultrafiltration, reverse osmosis, and ultraviolet light. Water will meet or exceed strict state and federal water quality standards before it is released into the ground.  Afterwards, water will undergo additional, natural filtration as it soaks through layers of soil and into the groundwater basin. Local water suppliers then follow state and federal standards for groundwater treatment so that by the time it gets to you it’s completely safe to drink.

The Greenspot Recharge Project, including treatment upgrades, would be funded by a combination of sewer rates, grants, loans, and bonds. The estimated project cost including construction and $7.1 M in Replenish Big Bear program development expenditures through April 30, 2026,  is $81M (in 2026 dollars). Annually, the project is estimated to cost $1.8 million for operations and maintenance.

Final design and construction are dependent on BBARWA Board approval. The Project Team is refining design components and estimated costs. The community and the BBARWA Board will be informed as more details become available.
