LOS OSOS GROUNDWATER BASIN
Plumbing Retrofit-to-Build

Return to Los Osos

The Retrofit-to-Build program (Title 19) requires all new development that uses water from the Los Osos Groundwater Basin to retrofit older plumbing fixtures in existing homes and businesses to save twice the amount of water the new development will use.

Effective March 10th, 2014, toilet and showerhead retrofit credits can no longer come from the Prohibition Zone.

A retrofit credit table has been developed to calculate the savings of each retrofitted house or business. Please utilize this table to calculate the water saving from each retrofitted fixture. Qualifying fixtures include: Toilets, showerheads, and clothes washers.  Water savings will be dependent on gallons saved per day based on the existing and retrofitted fixtures.  Property owners must obtain at least 300 water credits to obtain a Water Conservation Certificate and build a single family home.
