Get to Know Soldier Canyon Filter Treatment Plant
Soldier Canyon Filter Plant, located at the base of Horsetooth Reservoir, treats and distributes water for three local entities: Fort Collins-Loveland Water District, North Weld County Water District and East Larimer County Water District.
Fort Collins-Loveland Water District (FCLWD) receives the majority of the water it provides to 45,000 people in parts of Fort Collins, Loveland, Timnath, Windsor and Larimer County from the Soldier Canyon Filter Plant. The plant has some of the highest quality water in the area, which is measured and reported on quarterly for the plant, and yearly for FCLWD.
Soldier Canyon Filter Plant Expansion
Soldier Canyon Water Treatment Authority recently broke ground on an expansion to the Soldier Canyon Filter Plant, a project that will allow Soldier Canyon to meet peak summer capacity demands without relying on any other plants. It will also improve water quality with the construction of additional taste and odor facilities.
In addition to new construction, updates and improvements are being made to existing systems and equipment at Soldier Canyon Filter Plant. This ensures that the plant as a whole is able to adapt to new operating standards and serve customers for the long-term.
The expansion is being constructed offline, meaning minimal impact to FCLWD customers. At the end of the project, slated for 2021, it will be connected to the existing facility.
