Dominion Water and Sanitation District

A secure water future is a priority for Dominion Water and Sanitation District. While they are pursuing a number of projects and initiatives to achieve that goal, they also know that we will be stronger and more effective if they find ways to collaborate with neighboring communities and water providers. That is why they are members of South Metro Water Supply Authority, a group of 13 South Metro communities who are leading the way toward a renewable water supply future for the South Denver Metro region. Through collaboration, they are creating opportunities to partner on new water projects, building a stronger regional voice on water issues, and benefiting their water customers through greater efficiencies and economies of scale. SMWSA was founded in 2004 on unifying partnership principles, shared investments in projects and infrastructure, and gaining efficiencies through reuse and conservation.

Dominion is underway with the construction of a 2 million gallon water storage tank that will provide drinking water storage to current and future customers of Dominion Water, as well as commercial and residential fire flow capabilities.

Dominion Water & Sanitation District, a wholesale water, wastewater and stormwater provider for northwest Douglas County, has announced the start of construction of a two-million-gallon water storage tank in Douglas County. The $5 million High Zone Water Tank bond project will provide drinking water storage to current and future customers of Dominion Water, as well as commercial and residential fire flow capabilities, including the potential to serve residential and commercial demand along the Highway 85 corridor.

Tank construction is expected to be concluded by December 2020 enabling initiation of testing of the Dominion’s Eastern Regional Delivery System. The system is comprised of the WISE system and partnerships through Castle Rock and Parker, to the Dominion’s Eastern Regional Pipeline and the High Zone Water Tank. The 11-mile Eastern Regional Pipeline, also under construction and to be built this year, connects to the Town of Castle Rock’s water system and travels 11-miles along Highway 85 and rural areas in Northwest Douglas County to the High Zone Water Tank and on to the Larry D. Moore Water Treatment Plant. The High Zone Tank is a key piece of infrastructure for the east side of Dominion’s regional supply.

This system will connect Northwest Douglas County to the Water Infrastructure and Supply Efficiency (WISE) system, delivering renewable water supplies to residents of Northwest Douglas County and adding 1,325 acre-feet of water to Dominion’s already robust and reliable water supply portfolio.
