Wastewater System Improvements
(Last update 6/4/2026)
About the Project
We are currently underway on a major project to replace pipelines and improve our wastewater lift stations, which move wastewater through our system to treatment. We’re updating six wastewater lift stations and consolidating two others (for seven total stations). This long-overdue project will make our wastewater system much more reliable and involves upgrades across our service area.
Construction began in November 2025. Full completion is planned for the middle of 2027.
The first part of the project (2025-2026) includes:
- Installing a new wastewater lines between two of the sewage pump stations along Serena Drive and south into City open space. (Lift Stations 1&2) STATUS: Underway (more info below).
- Upgrading our lift station north of Hidden Point Blvd. and Serena Drive (Lift Station 1 Renovation Project)
- Permanently removing a sewage lift station (Lift Station 2) and adding a new gravity sewer and pipeline in the open space South West of Hidden Pointe Blvd and Monarch Blvd (northwest of the Briar Trace Drive cul-de-sac). STATUS: Underway (more info below).
- Replacing our lift station in the Hidden Pointe neighborhood, behind 343 and 355 Crossing Circle (Lift Station 5 Replacement Project). STATUS: Underway (more info below).

Wastewater Improvements Timeline
(Click to enlarge the map below. We will update this timeline with additional project work in late 2026 and 2027. The timing of construction on Lift Stations 3, 4, 6 & 7 is yet to be determined, but likely to start in summer or fall 2026. All lift station projects are currently scheduled to finish by mid-2027.)
Construction Impacts - What to Expect
Our team will post ongiong updates here on our website. This is your best and most up-to-date resource.
Impacts in Nearby Neighborhoods: The District is committed to proactive, transparent communication about impacts, detours, noise, and construction schedules. Construction impacts may include noise, equipment staging, increased truck traffic, and temporary lane/road and trail closures. The District will work to minimize construction impacts as much as possible, provide traffic control, maintain property access, keep trails open whenever possible, and coordinate in advance with local schools, neighbors and businesses.
For outages closures and signifiant updates we may post door hangers, mail notices to nearby homes/businesses,or send out notifications on our Daupler text messaging service! (sign up here if you haven't already). The District appreciates your patience as we work on these necessary upgrades and will work to minimize disruption however possible. All the stations and pipelines should be finished by the end of 2027, prepared to serve our community for decades to come.
Traffic & Noise Impacts: Lift Station 5 Construction
View Lift Station 5 resident notice
This project will include the installation of emergency overflow vaults designed to provide additional protection for the local environment and nearby waterways, as well as the replacement of the existing lift station with a new, modern system. These upgrades will enhance the reliability and resilience of critical wastewater infrastructure in the area. Construction is expected to continue throughout the summer months.
Traffic Impacts: Lift Station 1 & 2 Construction
Increased construction traffic along Hidden Pointe Blvd. and a short portion of Crossing Circle. We encourage residents to use caution when traveling in these areas.
Trail Impacts: Lift Station 1 & 2 Construction
A number of trails in the open space west of Briar Trace and Briar Haven Drive have temporarily re-opened for the summer months. The map below shows the remaining trail closure in the area: this portion will remain closed for public safety. The other local trails will be closed again later this fall future for additional construction. We will post updates here as they occur.
Q: Why can’t equipment be stored out of sight?
A: Vehicles and equipment must be stored within the project area in locations approved by the City of Castle Pines. This ensures that your neighborhood’s storm drainage is protected and the site is secure at the end of each workday.
Q: What is being done to keep the construction area safe and clean?
A: Our contractor is required to keep the construction sites safe and secure at all times. CPNMD staff will make routine visits to construction sites to ensure that they are being properly maintained. If any additional clean-up is needed, we will direct the contractor to do so.
Q: What will the project site look like once construction is over?
A: At project completion, the contractor is responsible for fully restoring the property to pre-construction conditions.
Q: Why does the trail remain closed?
A: The trail remains closed due to the need to complete restoration work, abandon the existing lift station, and connect the new wastewater force main to the existing infrastructure. The excavation extent was greater than initially anticipated, and the trail alignment is in direct conflict with some of this work.
Q: When will the trail re-open?
A: The trail will likely remain closed through the summer months. We may be able to temporarily open it; however we can't put a date on when that would take place. We will update the website if that becomes possible.
