Working together
Partnerships are at the core of how the South Metro Region is addressing our water challenges.
Not only have our members joined efforts through the partnership that is South Metro Water Supply Authority, they also have formed partnerships among themselves to collaborate on projects to provide new and renewable water supplies and infrastructure that help secure our region’s water future.
Arapahoe County Water and Wastewater Authority
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.
Cottonwood Water & Sanitation District
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.
Castle Pines North Metropolitan District
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.
Centennial Water and Sanitation District
Centennial Water & Sanitation District serves more than 100,000 people in Highlands Ranch and northern Douglas County. For nearly four decades, Centennial Water has planned the water supply for this community with innovative, conservation-minded practices. Centennial Water was the first water utility in Colorado to introduce water budgets as a primary water conservation tool. It has been successful in reducing water consumption by approximately 20%. Centennial Water's major water source, comprising approximately 85% of our water supply, is surface water from the South Platte River. That is supplemented with groundwater from deep aquifer wells throughout Highlands Ranch. Centennial Water's core values are safety, teamwork, vision, excellence in service and integrity.

Inverness Water & Sanitation District
The Inverness Water and Sanitation District (Inverness) has been providing water and wastewater services to its customers since 1972. Since its inception, Inverness has treated and reused domestic water supplies for irrigation which allows Inverness to augment the amount of water supply required to meet demands. In the late 1980’s, Inverness secured a portion of its renewable supplies through a partnership with Denver Water. With the addition of the WISE supply, Inverness is already set to meet over 80% of its potable buildout demands with renewable supplies. Inverness is very proud of providing safe drinking water to its customers and of its sustainable reuse system that ensures the maximization of our great but limited water resources in the region.
Dominion Water & Sanitation District
Dominion Water and Sanitation District was formed in 2004 to be a wholesale provider of water and wastewater service to Northwest Douglas County. Dominion's vision is to bring renewable water and access to centralized water and wastewater service to current and future residents of Northwest Douglas County. Our approach has been to leverage location, infrastructure and partnerships to create a regionally integrated, comprehensive water system with a robust, reliable and renewable water supply. Dominion partners with local water and wastewater providers in the Denver metro area to leverage regional assets, efficiently serve our customers and solve regional problems.
East Cherry Creek Valley Water and Sanitation District
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.
Pinery Water and Wastewater District
The Pinery Water and Wastewater District is devoted to providing Quality Water for LIFE by providing safe, clean and sustainable water and wastewater service at a fair price. The District is 75% of the way to its maximum population and is currently focused on replacing its aging and most impacted infrastructure through implementing its comprehensive Asset Management Program. One of the most significant projects in that program is the Potable Pipeline Replacement project. Pinery is also committed to providing customers with a renewable supply of water through the WISE project and recently completed the infrastructure necessary to deliver WISE water to its customers. Pinery's second renewable water project, which includes raw water storage and a series of new wells, is also nearly complete.
Meridian Metropolitan District
The Meridian Metropolitan District has developed a state-of-the-art system that provides the highest quality water/wastewater treatment services to a mixture of large office complexes, small businesses, restaurants, apartment buildings, and residential properties. Its innovative approach to wastewater treatment enables it to recycle 100 percent of its water, an environmentally responsible strategy that provides a sustainable source of irrigation water for the District and serves as the backbone of its conservation strategy. The staff for the District utilize their extensive expertise in water and wastewater to serve the needs of every utility customer and to meet the District’s goals of delivering safe and reliable water/wastewater services, maintaining the District as one of the premier mixed-use communities in Colorado, and providing the best customer service.
Parker Water & Sanitation District
The vision of Parker Water and Sanitation District (PWSD) is “Sustaining Life for Our Community,” and it strives to achieve this through a focus on conservation, education, and investing in renewable supplies of water. A commitment to improving the environment runs deep in the organization and can be seen in its efforts to reduce energy consumption, implement sustainable water treatment, and reduce reliance on nonrenewable groundwater. PWSD is a strong advocate of regional partnerships, which is why it was one of the first partners in the Water Infrastructure Supply Efficiency project that shares water supply and infrastructure with other providers to bring renewable water supply to the south metro region. Since joining WISE in 2009, PWSD has invested in developing state-of-the-art treatment facilities and other infrastructure needed to bring this renewable water to its customers.
Rangeview Metropolitan District
Rangeview Metropolitan District is a regional water and wastewater provider with a mission to deliver safe, great tasting, pure water from its source to its customers, with a focus on our customers and conserving our planet's most valuable resource. Rangeview’s service area includes the more than 24,000-acre Lowry Ranch in Arapahoe County, as well as the I-70 corridor’s newest Master Plan Community, Sky Ranch. Rangeview has an extensive portfolio of surface water, groundwater, and surface reservoirs, together with two zero discharge wastewater reclamation plants that aim to protect, preserve, use and reuse our valuable Colorado water supplies to their fullest extent. Rangeview’s distribution systems include both domestic and reuse water distribution systems to be able to use its highly treated effluent water supplies for outdoor irrigation demands in our parks and open space areas.
Stonegate Village Metropolitan District
The Stonegate Village Metropolitan District manages and oversees the operations of the many utilities, infrastructure, and services which ensure an outstanding quality of life for its customers in northern Douglas County. These include water and wastewater resources, recreational facilities, open space areas, public landscapes, and drainage-way maintenance. These District services are maintained and operated by funds received through property taxes or fees, and are used for the operation, maintenance, and long-term replacement of District facilities, resources and infrastructure. Additionally, the District supports a variety of special projects and programs that directly enhance and improve the community, including its renewable water program, water plant facilities upgrades, open space and park improvement projects, community development planning and Community Center improvements and more.
Castle Rock Water
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.
