The district has been the governing authority over wastewater management in the western part of the unincorporated areas of Washington County since 2009 when the Washington County Commission passed a resolution for this purpose. The area west of Interstate 15 and Kolob are managed by the district; east of Interstate 15 and New Harmony are managed by the Ash Creek Special Service District.
Wastewater management is necessary to protect ground water recharge areas and drinking water sources. Should these areas become contaminated with pollutants or toxic compounds, the health of our residents and environment could be compromised.
The district is currently expanding the Dammeron Valley wastewater system to meet federal and state guidelines, protect groundwater supplies and allow for additional growth. Inforamtion on the expansion is available here.
Most septic systems do not remove all pollutants so regulations are established to limit the number of systems in a given area. Studies have been performed to determine septic densities per acre here in Washington County.
The septic density standards establish the number of septic tanks that can be installed, while still minimizing contamination of groundwater resources. The studies took into account the subdivisions already in place and recommended limitations in each area.
These studies have been posted below for your convenience.
For the following areas: Pine Valley, Brookside, Veyo, Gunlock, Ivins, Santa Clara, Washington, Dammeron Valley, Diamond Valley, Winchester Hills, New Harmony, Anderson Junction, Hurricane, LaVerkin, Leeds, Pintura, Sky Ranch/Bench Lake area, Toquerville and Apple Valley
Determination of Recommended Septic System Densities for Groundwater Quality Protection
prepared by Hansen, Allen & Luce, 1997
Any areas not addressed in these studies may require sufficient acreage and/or the completion of an engineering study to determine an allowable septic density.
If the septic density requirements are not met and you cannot connect to an existing wastewater treatment facility, an approved alternative wastewater system will be required.
Instructions, application forms and certifications are available below.
