Unlocking Potential Treatment Capacity and Reducing Capital Cost

Aging treatment plants and changing raw water quality threaten the resiliency of the drinking water supply of many utilities. For existing WTPs, custom solutions developed with strong collaboration with plant staff are required to replace obsolete facilities and help utilities prepare for the future while minimizing capital costs and related project risk.

The Soldier Canyon Filter Plant (SCFP) operated by the Soldier Canyon Water Treatment Authority was constructed in 1962 as a direct filtration plant in Fort Collins, Colorado. Upgrades since that time include flocculation and sedimentation basins, additional filters, and solids handling systems. The Authority was considering a $48 million capital program to expand the plant to 60 mgd, including adding six new filters. By creatively demonstrating high filtration rates to state regulators, project costs have been reduced to approximately $38 million. New work includes installing new pretreatment trains, new chemical systems, correcting hydraulic deficiencies, improving the plant’s electrical infrastructure, and providing a robust new disinfection process.

This presentation will discuss key design considerations of creative plant upgrades for existing WTPs. Strategies employed at the SCFP will be featured, including a pilot and full scale demonstration test to gain 15 mgd greater capacity without expanding or adding new filters.
