What is this service?
The Retrofit-to-Build program (Title 19) requires all new development that uses water from the Los Osos Groundwater Basin (LOGWB) 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.
Who can use this service?
Anyone building a new structure that will use water from the Los Osos Groundwater Basin is subject to the requirements of the Retrofit-to-Build Program.
Is there a charge for this service?
The developer is responsible for the cost of the required replacement fixtures.
When and where is this service offered?
This service is available throughout the year during regular business hours except during scheduled holidays.
