Water Conservation

On October 27, 2015, the Board of Supervisors adopted Resolution 2015-288, which established the Countywide Water Conservation Program (CWWCP) in response to the declining water levels in the Nipomo Mesa Water Conservation Area (NMWCA) part of Santa Maria Groundwater Basin), Los Osos Groundwater Basin (LOGWB), and the Paso Robles Groundwater Basin (PRGWB). A key strategy of the CWWCP is to ensure all new construction and new or expanded agriculture will offset its predicted water use by reducing existing water use on other properties within the same water basin. The CWWCP has created services within each the NMWCA, LOGWB, and PRGWB, to assist with water conservation.

To determine whether your property is within one of the three basins offering water conservation services, launch the Land Use View and look up your property by assessor parcel number or address. In the bottom left corner of the Land Use View webpage, click the "Layers" icon, expand the Planning layer, expand the Impacted Groundwater Basins layer, and check the box for Groundwater Basins at LOS III.

Each of the three groundwater basin areas has specific policies that apply.  For more information on the policies and programs that apply to each of the groundwater basin areas, please visit the Countywide Water Conservation Program Website

Agriculture Offset Program

The Agricultural Offset program is an implementation tool and is intended to substantially reduce increases in groundwater extraction and lowering of groundwater levels in the PRGWB (excluding the Atascadero Sub-basin) only.

Cash for Grass

The Cash for Grass program offers incentives to property owners in the PRGWB and NMWCA who are seeking to replace irrigated turf and replace it with approved low water using plants and groundcover.

Incentives are available to qualifying property owners on a first-come, first-served basis while funding is available. The Program generates water savings credits that can be purchased by applicants from within the same groundwater basin who need to meet water neutrality requirements for new construction. Funding availability is subject to change at any time.

Those interested in the Cash for Grass Program may submit a completed application and a signed copy of our terms and conditions

All plants used to replace current landscaping must be selected from our approved plant list.

Retrofit-to-Build Program (Title 19)

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.

Plumbing Retrofit Program in Paso Robles Groundwater Basin

The County has partnered with the Wallace Group to administer and operate the Plumbing Retrofit Program, which replaces high-flow plumbing fixtures with low-flow plumbing fixtures in homes that are located within the Paso Robles Groundwater Basin area with the goal of reducing daily water use in the area.

Retrofit-on-Sale Plumbing Verification

The Retrofit-On-Sale Program (Title 8 Retrofit Certificate) is a requirement for all homes being sold in the Los Osos Groundwater Basin (LOGWB) area or the Nipomo Mesa Water Conservation Area (NMWCA). This includes homes that were built after 1994 and homes that were previously issued a Title 8 Retrofit Certificate. The certificate is a formal County-approved document that certifies that the home being sold meets all retrofit requirements for the existing plumbing fixtures (toilets, showerheads, faucet aerators) in the home.

Washer Rebate Program

The Washer Rebate Program offers monetary incentives for property owners in the PRGWB and NMWCA area who are seeking to remove their high-water using clothes washer and replace it with an Energy Star certified clothes washer with an integrated water factor (IWF) of 3.2 or less.  Incentives are available to qualifying property owners on a first-come, first-served basis while funding is available.  More information on how to calculate the GPD savings between the old and new washers can be found within the Washer Rebate Program application.
