About the Thornton Water Project

Project Information

The Thornton Water Project Website has been established to keep the public informed about the pipeline in Larimer and Weld Counties that will bring water purchased in the 1980s to Thornton customers.

Thornton’s water customers will need this additional water supply by 2025. Project permitting and easement acquisition is currently underway; design started in mid-2018, and construction will start in mid-2019.

We have one of the lowest per-person water usage rates in the state, and will continue to be a leader in water conservation, but conservation alone isn’t sufficient to meet our ongoing and future water supply needs.

Larimer and Weld County Permit Segment Map

We want to continue to be a good community neighbor and collaborate with stakeholders early in the process. In addition, it takes many years to perform the necessary studies and designs, acquire the necessary approvals and easements, and construct a 70-mile-long pipeline (click on image on the right to see the Larimer and Weld County Permit Segment Map).

The specific location of the pipeline has not been determined for the majority of the corridor.  We have identified a specific alignment and location for the pipeline in portions of southern Weld County, and we are working with property owners to acquire the necessary easements for the pipeline in those locations.  We anticipate that the pipeline diameter will be in the 48-inch range and it will be buried with some appurtenances and access points above ground.
