Cole said Dominion is a wholesale water and wastewater provider for northwest Douglas County, formed in February 2004, serving Sterling Ranch and neighboring communities. Dominion said it relies on a mix of supplies: two firm contracts with the City of Aurora (totaling 480 acre‑feet annually), 1,325 acre‑feet of South Metro WISE allocations (interruptible), agreements that firm 700 acre‑feet with Castle Rock and planned Cherokee Ranch groundwater (625 acre‑feet) for firming, plus junior South Platte rights and planned reusable return flows at buildout.

Cole described existing and planned infrastructure: the 11‑mile Eastern Regional Pipeline (30‑inch diameter) that will carry WISE deliveries into northwest Douglas County and is being disinfected for operations expected to begin in May; a 2.0 million‑gallon high‑zone tank and a ~1.0 million‑gallon low‑zone tank for distribution; and multiple turnout points for future connections. Dominion is constructing a Filing 7 lift station and force main now.

On wastewater and reuse, Cole said Dominion has a progressive design‑build contract with PCL and Stantec to construct the Chatfield Basin Water Reclamation Facility, a 0.9 MGD membrane‑bioreactor plant funded in part by a $20 million ARPA contribution from Douglas County. Cole gave an estimated project cost of $34 million for the plant and said construction will begin in summer 2025 with full operation targeted for January 2028. Dominion also received a CWCB grant of $866,000 to advance design of a South Platte diversion, and estimates the diversion/pump station/pipeline project cost at $26 million with construction targeted for completion by 2029.

Cole said the diversion, located downstream of the wastewater plant site, is critical to capture return flows and to take advantage of Dominion’s adjudicated South Platte junior rights (25 cfs) and 500 acre‑feet of storage in Chatfield Reservoir. Dominion also noted the project requires federal permits, including Clean Water Act Section 404 and Section 408 permits, and that permitting is a major schedule risk.

She described Dominion’s focus on demand management and efficiency: Sterling Ranch has achieved low indoor per‑household use (about 0.13 acre‑feet per single‑family equivalent indoor use) and a total target near 0.2 acre‑feet per year per single‑family equivalent. Tools include indoor/outdoor dual meters, tiered water budgets, smart irrigation controllers and strict landscaping standards. Dominion is also piloting regional rainwater harvesting and PFAS treatment on the wastewater side.

Commissioners asked about the status of Cherokee Ranch groundwater rights (Cole said they are deeded and decreed), the Corps’ minimum streamflow obligations downstream of Strontia (Cole described a 2012 amendment establishing summer/winter flows), and the firming arrangements with Castle Rock and Aurora. Cole said Aurora supplies are delivered through the Rampart system now and will be delivered via the river once Dominion’s diversion is online.

Cole summarized near‑term construction and permitting steps: disinfecting the Eastern Regional Pipeline now, starting water deliveries in May, completing the South Platte diversion 60% design in 2025 with CWCB support, starting the regional wastewater plant progressive design‑build construction in summer 2025 and targeting diversion construction by 2029. She said the district’s long‑term portfolio at buildout is modeled at about 3,986 acre‑feet per year including reusable return flows (about 1,529 acre‑feet per year assumed at buildout).","mediaType","Video","parentTitle","Douglas County Water Commission Meeting – March 24, 2025","oneSentenceSummary","Dominion Water & Sanitation District presented its service area, supply portfolio and major projects including the Eastern Regional Pipeline, a South Platte diversion and a Chatfield Basin wastewater reclamation facility.

Commissioners said the county should focus first on assembling reliable data about supply and demand, then address policy and financing questions. Staff described changes to the questionnaire — notably separating questions about reusable water, simplifying tables and keeping a public-facing one‑pager and QR code to route feedback to the project website.

The commission’s staff member Lauren Pulver introduced the packet and said the county and consultants had “been working with our water consultants to put together public outreach materials and kind of refine the strategy for public outreach.” Will (consultant) summarized edits to the provider survey and said section 4 now separates reusable water and reduces table complexity to improve clarity.

Commissioners pressed for standardized definitions and more granular data. Commissioner Trisha Bernhardt urged the county to watch cumulative groundwater impacts after noting the Antelope Crossing application proposes four lots and four new wells in the Lower Dawson area and said, “cumulatively, all of these start adding up.” James Eklund, Evan Hila and others asked that the questionnaire define terms such as “firm yield” and “reusable,” and request items that would make responses comparable across providers — for example, the basis used to calculate firm supply and 10‑year per‑capita use trends (winter and summer averages).

Several commissioners recommended breaking input by planning zones. Commissioner Clark Hamillman suggested including elected officials from municipalities and special districts in focus groups to capture constituency concerns. Commissioner Harold Smethals and others argued that the first round of focus groups should concentrate on getting the right technical data rather than debating policy, and that policy discussions should happen later once the data is compiled.

Consultants and staff agreed to consider zone-based delineation for focus groups and said they would request conservation plans from providers where available. Will also confirmed the survey asks providers to provide conservation plans and that staff will seek additional financial and project-planning details (debt, planned projects) because such information could influence future county participation in regional projects.

Commissioners and staff discussed how to help very small water districts complete the survey. Staff acknowledged many small districts are volunteer-run and said the county will try to assist smaller providers and accept reasonable assumptions where detailed data is unavailable.

The commission also agreed to fold some stakeholder outreach into topic-centered focus groups — for example, separate groups for retail water providers, individual well owners and developers — rather than creating a separate standing stakeholder committee. Commissioners emphasized keeping the outreach materials public-facing and easy to act on; James Eklund recommended a clear call to action on the one‑pager and suggested language such as: “We want to hear from you.”

The meeting opened with a routine roll call and concluded earlier formal business with approval of prior meeting minutes before the water plan discussion. A motion to approve the minutes was made, seconded and approved with two abstentions recorded (members who said they had not attended the prior meeting).","Commissioners reviewed edits to a water-provider questionnaire and a public outreach plan for the county's water master plan, asking for clearer definitions, zone-based data, and help for small water providers.
