South Platte Renew outlines costly infrastructure upgrades and nutrient treatment projects

The Englewood Water and Sewer Board meeting on April 8, 2025, focused on critical infrastructure projects aimed at improving water quality and addressing aging facilities. Key discussions highlighted the need for significant investments in nutrient removal technologies and the rehabilitation of outdated infrastructure.

One of the most pressing issues discussed was the implementation of cooling towers at the South Platte Renew facility. This project is necessary to manage the temperature of water discharged into the river, which currently exceeds regulatory limits during certain times of the year. The cooling towers represent a substantial financial commitment, and the board is actively collaborating with the Colorado Department of Public Health and Environment (CDPHE) to explore alternative solutions that could mitigate the environmental impact and energy consumption associated with cooling towers.

The board emphasized the importance of innovative approaches to water treatment, including ongoing research into advanced technologies for phosphorus removal and nutrient management. These efforts are part of a broader strategy to enhance operational efficiency and reduce long-term costs.

Financial projections indicate a significant increase in funding requirements, with anticipated costs rising from approximately $15 million annually to between $34 million and $35 million by the early 2030s. This shift reflects the urgent need to address both nutrient treatment challenges and the replacement of aging infrastructure, such as the Headworks Building, which is nearing the end of its operational lifespan.

In conclusion, the meeting underscored the Englewood Water and Sewer Board's commitment to maintaining compliance with environmental regulations while investing in the future of the city's water infrastructure. The board's proactive stance on exploring new technologies and solutions aims to ensure sustainable water management for the community.
