ACWWA provides water to 31,000 people in Arapahoe, Douglas, and Elbert Counties. Like many members in SMWSA, ACWWA is focused on decreasing reliance on nonrenewable groundwater through projects such as the ACWWA Flow Project, a partnership with East Cherry Creek Valley Water and Sanitation District and United Water and Sanitation District that when completed, will deliver an average of 4,400 acre-feet per year of renewable water to its service area. Another project in collaboration with Cottonwood Water and Sanitation District is the Joint Water Purification Plant that will be able to produce 3 million gallons of high-quality water per day from renewable supplies. These projects will allow ACWWA to meet its demands entirely with renewable supplies and reserve its groundwater for emergency drought situations.

The Cottonwood Water and Sanitation District (Cottonwood) is one of many South Metro water providers whose initial water supply came mainly from nonrenewable ground water. Starting in 2004, Cottonwood and its long-term partner, the Arapahoe County Water and Wastewater Authority, planned and developed the Joint Water Purification Plant whose treatment (MF+RO+AOR) provides a high-quality supply with low TDS and eliminates Chemicals of Emerging Concerns. Moreover, the plant allows for full use of Cottonwood’s renewable supplies on Cherry Creek that, combined with the WISE Supply, should meet 75% of Cottonwood’s buildout demands. Cottonwood and its partners continue to refine their strategy for drought supply to ensure a long-term sustainable water system for the District’s customers and the region combined.

The Castle Pines North Metro District (CPNMD) provides clean, safe, reliable, on-demand drinking water, wastewater, stormwater, parks, trails, and open space services to approximately 3,400 residential and commercial customers in the City of Castle Pines. Voter opposition in 2016 & 2018 to two renewable water plans (each well-over $100 million) prompted the election of a reform team of directors last year. CPNMD is now working diligently to secure its renewable water future wisely and at less cost than the previous two voter-rejected plans. CPNMD and the Parker Water & Sanitation District recently launched a Water & Wastewater Service-Integration Feasibility Study that will soon reveal the costs/benefits of integrating the water and wastewater services of both jurisdictions and the degree to which doing so would minimize cost-of-service escalation in future years.

East Cherry Creek Valley Water and Sanitation District (ECCV) sustains a community of approximately 55,000 residents in portions of Centennial and unincorporated Arapahoe County by providing safe, reliable water and sewer services. The District is customer focused but recognizes the importance of regional partnerships such as ECCV's Northern Project where renewable water from the South Platte is treated at the District's state-of-the-art Northern Water Treatment Plant and transported 31 miles to ECCV customers. The Arapahoe County Water and Wastewater Authority (ACWWA) is also a partner in the project, receiving renewable water through the facilities. In 2014, ECCV transferred ownership of an existing east-west waterline to the South Metro WISE Authority (SMWA) and Denver Water to facilitate delivery of renewable water supplies to members of the SMWA while also maintaining capacity to provide water to ECCV's customers. Through this involvement ECCV continues to work toward providing its community with a fully sustainable water supply.

Castle Rock Water is securing a strong water future. In addition to providing 72,000 residents with drinking water, wastewater service and stormwater protection, ensuring a sustainable water future is a top priority. Once solely reliant on the slowly diminishing groundwater, Castle Rock is transitioning to renewable sources which is projected to make up more than 75 percent of all water used in Town by 2055. These renewable sources include local surface water, imported supplies, storage in reservoirs, conservation, and reuse. Renewable water projects include adding surface water wells, expanding the imported WISE water supplies and securing water sources into storage facilities. Castle Rock Water is expanding the Plum Creek Water Purification Facility and distribution lines to fully utilize potable and non-potable reuse water by 2020.
