The City of Greeley's Water Pollution Control Facility (WPCF) was chosen as the recipient of the 2011 Plant Performance Merit Award presented by the Rocky Mountain Water Environment Association (RMWEA). One award is presented annually to a wastewater plant in the three-state area of Colorado, Wyoming and New Mexico.
This award is for wastewater treatment plants and recognizes outstanding efforts in plant operations, maintenance or public relations, which occurred because of the concerted efforts of all personnel associated with plant management and operations. The WPCF provides quality, safe and cost effective wastewater treatment services for the citizens of Greeley. The goal of the WPCF is to maintain or improve the water quality of the Cache la Poudre River. The WPCF staff has shown excellence in the area of operations, maintenance, laboratory testing, professional development, safety and public education.
Removal of wastewater contaminants is outstanding at the WPCF. For example, in 2010, the annual average percent removal rates for Carbonaceous Biochemical Oxygen Demand (CBOD5), Total Suspended Solids (TSS), and Ammonia-Nitrogen were 98 percent, 95 percent, and 75 percent, respectively. While removal rates exceed federal and state standards, WPCF is always improving. As a part of a current plant aeration improvements project, existing multi-stage centrifugal blowers have been replaced with new high-speed turbo blowers. It is estimated that these new blowers will save the plant approximately $120,000 - $180,000 annually in projected electrical energy costs. The project will also increase the aeration capacity of the biological treatment process enabling a greater removal of ammonia. Completion of this project is anticipated in August 2011.
Tom Dingeman, Wastewater Treatment Superintendent, will accept the award at the RMSAWWA/RMWEA Annual Conference in Loveland, Colorado in September. This is the fourth time Greeley WPCF has received this prestigious award, winning previously in 2005, 1999 and 1992.
