ENGLEWOOD, Colorado — South Platte Renew is a wastewater treatment plant that processes raw sewage from Englewood and Littleton. It is the third-largest wastewater treatment plant in Colorado. 

The team has been collecting samples to test for COVID-19 since the beginning of the pandemic. The plant participates in two sampling programs. One is based in Colorado, and the other is a national program. 

New data shows a huge spike in the COVID concentration in raw sewage, a figure that is almost double right now compared to numbers last winter.
