WASTEWATER: Big Dry Creek Wastewater Treatment Facility
21-June-2021
The Institute for Sustainable Infrastructure (ISI) proudly announces the most recent recipient of the Envision Bronze award for sustainable infrastructure is the City of Westminster’s Big Dry Creek Wastewater Treatment Facility (BDCWWTF). This is the City of Westminster’s first Envision award.
The City of Westminster, located just north of Denver CO, owns and operates the BDCWWTF which is located in the northeastern most area of the City’s wastewater collection system. The BDCWWTF is designed for biochemical oxygen demand removal, nitrification and denitrification, and limited phosphorous removal. The facility has undergone several major upgrades over its 30-year operational life so far, with the most recent expansion in 2009. A few years ago, the City of Westminster commissioned a Solids Handling Master Plan (Plan) for the facility. This Plan led to the Solids Dewatering and Campus Wide Improvements project at the facility, which was the subject of the Envision verification. This project provides the City with new solids dewatering equipment and facilities, an improved central handling system, enhanced nutrient removal, biosolid beneficial use optimization at the City’s farm, operational optimization, and campus-wide improvements throughout and around the facility.
