Much-needed Upgrades & Repairs

We are hard at work making important changes to our system! The current district staff and board inherited an old water/wastewater system with minimal replacements and repairs. This reality has presented various challenges, but also the chance to make meaningful improvements to benefit our community for the future.

The district is completing a comprehensive audit of its infrastructure to ensure we understand our system and its current needs. Our current and outlined projects (listed below) are necessary to modernize the system, prevent future violations and make our system more structurally sound for possible partnerships with neighboring water districts.

Project Costs

All project costs are carefully considered and documented in board proceedings. We’re a small water district, which means that our project costs are directly reflected in the cost of our services. For this reason, we prioritize the most pressing repairs and upgrades first while always looking for ways to collaborate with the City and reduce costs as much as possible.

Projects are paid for through water rates (based on individualized water budgets) and new customer tap fees. To help ensure we have the funding needed to keep this momentum going, we conducted a water rates study this past summer and recently adjusted our rates and fees to complete these key projects and continue delivering quality, safe water and wastewater services to our customers.

CURRENT PROJECTS (To Date): 

Wastewater System Upgrades:

  • Read the project's dedicated page.
  • What: We’ve begun critical work to improve the wastewater lift stations that move wastewater through our system to treatment. We’re updating six wastewater lift stations and consolidating two others (for seven total stations).
  • When: Began in November 2026 and is planned for completion in 2027.
  • Why: The upgrades will make our wastewater system much more reliable. 
Workers lower and install a new, large concrete overflow vault into Lift Station 1 as part of construction on the station.

Water Treatment Plant - Filter Improvement Project:

  • What: Based on the previous successful pilot study, we are adding new filters during the winter and spring when the plant is offline for the winter. 
  • When: The new filters are being added and should be finished by mid-2026.
  • Why: This is the last of many upgrades needed at the plant to improve its performance and treat an additional two million gallons of water per day to meet current demand.

District System Assessment:

  • What: The district is completing an ongoing comprehensive review of all our infrastructure—wells, pump stations, treatment plant, and distribution lines.
  • When & Why: The initial review will be completed in 2026 and provide insight on future district projects and opportunities.

Study on Opportunities for Local Collaboration:

  • Also known as: Northwestern Douglas County Regional Water Supply Reconnaissance Study
  • What: the District is participating in a water supply study with Castle Pines Metro District, Dominion Water & Sanitation District and Highlands Ranch Water, among others. This study investigates opportunities to enhance our existing regional connections, such as our winter supply agreement with Highlands Ranch Water through Chatfield Reservoir.
  • When & Why: The study’s initial results have been delivered, and additional work is underway to determine the best opportunities to pursue. This study is expected to offer some important options to improve district collaboration in 2026, and the District will provide more details once we have final results.
