A brief description of the institution’s sustainable wastewater systems and technologies:
Colorado College employs Colorado Springs Utilities (CSU) to handle its wastewater. CSU exceeds its permit requirements to ensure that water is treated in a way that minimizes potential harm to local waterways. As a secondary treatment to wastewater, CSU employs the use of bacteria and other microorganisms which are fed oxygen which allows them to grow and consume other organic materials. Nitrifiers convert ammonia into nitrogen gas while other micro-organisms aid in the removal of phosphorous. All micro organisms are then removed through settled and are reused time and time again. The facility utilizes ultraviolet (UV) light to disinfect wastewater, which eliminates bacteria and enhances the quality of wastewater discharge. The treatment plant has adapted these methods to replace its previous use of gaseous chlorine.
