Sand Creek WWTP, Aurora, Colorado - Wastewater Treatment Plant

Sand Creek WWTP is a municipal wastewater treatment facility located in Aurora, Colorado, serving a population of about 67,783. The plant is situated in the South Platte River watershed, an important waterway in the Denver metropolitan area. As a medium-sized agglomeration, the plant is expected to meet secondary treatment standards under the U. S. Clean Water Act, with National Pollutant Discharge Elimination System (NPDES) permits issued by the Colorado Department of Public Health and Environment. These permits set effluent limits to protect water quality in the receiving stream. The treated effluent from Sand Creek WWTP discharges into Sand Creek, a tributary of the South Platte River, which flows through Colorado and Nebraska before joining the Platte River. The South Platte River supports diverse aquatic life and provides water for irrigation, recreation, and municipal use downstream.

The plant discharges into Sand Creek, which flows into the South Platte River, a major waterway in the western United States. The South Platte River ultimately drains into the Platte River and then the Missouri River, part of the Mississippi River basin. The watershed supports a variety of fish species and provides critical habitat for migratory birds along the Central Flyway.
