A brief description of the natural wastewater systems used to handle the institution’s wastewater:

As part of the Colorado Springs Utility service territory, Colorado College employs Colorado Springs Utilities (CSU) to handle its wastewater. Wastewater from Colorado College is treated at CSU's Las Vegas Street Wastewater Treatment Facility. The plant uses bilogical processes in secondary treatment after mechanical filtration in the primary treatment. The biological processes use beneficial microorganisms in holding tanks to remove pollutants from the wastewater. The process removes excess phosphorous and nitrogen to discharge standards into local waterways. A third stage employs a UV light disinfection system, which replaced an outdated chlorine system in 2010. This final disinfection allows CSU to exceed its permit requirements in eliminating bacteria and enhancing the quality of wastewater discharge.
