Due to a State mandate to protect local groundwater quality, septic tank discharge in our area will be prohibited in the upcoming years. Some portions of the district will see this septic ban take effect as early as May 19, 2016 June 30, 2021.

Hi-Desert Water District has developed a solution that is a comprehensive, community-wide approach to meeting the state’s requirements and keeping local water safe and healthy for generations to come. It would provide for the safe and cost-effective collection and treatment of wastewater for residential and commercial customers throughout the service area.

The project consists of:



The wastewater collection system is comprised of 77 miles of pipeline in Phase One, with more to come in Phases Two and Three. The system will be predominantly gravity fed, reducing energy costs, with three lift stations helping move wastewater uphill where necessary. Pipes ranging from 8 inches to 24 inches in diameter will provide service up to the property line of homes, businesses and vacant land.



The wastewater treatment plant, which will be located on 20 acres near Home Depot, will use membrane technology to treat wastewater delivered by the wastewater collection system. Phase One of the Project is expected to collect and treat one million gallons of wastewater per day. As Phase Two and Three come online, the capacity will be expanded to meet the additional demand.



Water reclamation recharge ponds near the treatment plant will be filled with clean, treated water. The water will percolate into the ground and help replenish the aquifer. In the future treated water may also be used to irrigate areas with large landscapes. Hi-Desert Water District will continue to explore other beneficial uses of the treated wastewater in years to come.



Project completion would ensure compliance with State requirements, prevent local residents from being fined for continued septic tank discharge, and most importantly protect local groundwater.

The project will be built in three phases that are divided by location. The Phases were developed to ensure compliance with the State prohibition, and to allow the community time to design and construct the infrastructure required to comply.

As phases two and three come online the Wastewater Treatment Plant will be equipped to handle the increased capacity.

Phase One – Expected completion May 2019 December 2020

Phase Two – Expected completion 2022 2025

Phase Three – Expected completion 2025 2025
