NEW Permit Application - Engagement

Raw Water Pump Station Tours

As a part of the Thornton Water Project, the city of Thornton is proposing to construct a raw water pump station adjacent to Water Supply and Storage Company Reservoir No. 3.  The city will host site visits to two existing pump stations, located in Thornton, to provide Larimer County residents an opportunity to view operational pump stations.

Tour dates are as follows:

The tour will begin at Thornton Fire Station Number 5 located at 14051 Colorado Boulevard, Thornton, CO 80602.  Transportation to the pump station sites will be provided in city of Thornton vehicles and attendees will be required to sign a waiver.  The tour will last approximately 90 minutes.

Reservations are required. Each tour will be limited to 8 people.  Additional tours may be added if interest is high.

NEW Permit Application – Engagement

On November 20, 2023, with an appreciation to the many Larimer County landowners and community stakeholders who provided valuable input over the last year, the city of Thornton formally submitted a new application asking Larimer County to approve a permit to build a buried water pipeline for transporting water to Thornton. The Thornton Water Project will deliver an average of 14,000-acre feet of high-quality water Thornton owns in the Water Supply and Storage Company System (WSSC) to its residents. This project is critical to ensure water supply reliability and drought resiliency, to provide drinking water that is protective of public health, safety and welfare, to support the availability of housing and to meet municipal water demands in the city through 2065.

After one-on-one meetings with many local landowners and community stakeholders, two public informational meetings, and gathering additional input through surveys, Thornton staff listened and learned about concerns regarding impacts that the construction of a pipeline might create in Larimer County. This extensive engagement resulted in several significant changes to the pipeline alignment previously proposed in 2018 which Larimer County denied.

Specifically, Thornton staff participated in two open houses in Larimer County, and hired a third-party consultant to conduct a survey which was sent to the over 400 property owners within the project area. Thornton also heard concerns about perceived impacts the Thornton Water Project might have on the Poudre River. An educational component was added to the open houses and all outreach to inform attendees that the project creates no new impacts to flows on the Poudre River. The water Thornton owns is stored in reservoirs and has come out of the Poudre River in the same location and same amount since the 1890’s.
