Protecting Our Water Supply Through Wastewater Management
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 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.
Dammeron Valley Wastewater System
In 2017, the district completed an expansion of the Dammeron Valley wastewater system to meet federal and state guidelines, protect groundwater supplies and allow for additional growth. Information on the expansion is available here.
The district manages this system’s main sewer line; sewer laterals are not part of the district’s system as outlined in this disclosure statement.
Septic Density Studies
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 in Washington County to determine septic densities per acre. 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.
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.
