Wastewater Treatment

Over half of Westminster's wastewater travels through an efficient and environmentally sound treatment and reclamation pathway to the Big Dry Creek Wastewater Treatment Facility. This facility has been recognized by the EPA and the State of Colorado for its treatment processes and stewardship of the environment. Big Dry Creek Wastewater Facility has the capacity to treat up to 12 million gallons a day.

The other half of Westminster's wastewater travels to the Metro Wastewater Reclamation District in Denver, which has the capacity to treat up to 150 million gallons per day. The Metro District provides wholesale wastewater transmission and treatment service to 55 local governments or approximately 1.3 million people in the Denver metropolitan area.

Biosolids Land Application Program

The Utilities Operations Division oversees a unique wastewater management program, an environmentally sound program that has propelled Westminster to a leadership position among American cities of its size. During the wastewater treatment process, organic solids, called biosolids, are separated out. These biosolids are treated using a special process and transported to the city's Strasburg Natural Resource Farm for soil conditioning. Rich in nitrogen, organic matter and trace nutrients, these biosolids are an ideal additive for depleted soils. The use of these biosolids is strictly regulated to protect the groundwater, soils, livestock and people. In 1996 the city purchased a 2,000-acre farm in Strasburg, Colo., in order to land apply biosolids from Big Dry Creek Wastewater Treatment Facility.
