South Platte Renew, which serves 300,000 customers in both Littleton and Englewood, has transformed wastewater treatment into a success story in renewable energy. … The team at South Platte Renew considered how to capture the methane gas and reuse it, eventually proposing a biogas pipeline injection system in 2019. It was approved, and the $7.8 million price tag was paid for through sewer funds from Englewood and Littleton. It was the first of its kind system in the state of Colorado. … South Platte Renew has now helped other water treatment facilities in the state get their systems up and running.
