The City of Crystal Lake has engaged Trotter and Associates, Inc. (TAI) to undertake a significant rehabilitation project at Wastewater Treatment Plants (WWTP) Nos. 2 and 3. This project aims to enhance the efficiency and effectiveness of the wastewater treatment processes in alignment with the City’s Wastewater Master Plan and recent Phosphorus Removal Studies.

The project scope for WWTP2 will involve replacing four raw sewage pumps and the primary clarifier cross collectors, rehabilitating the secondary clarifier, and converting the tertiary filtration process from sand filters to cloth media disc filters. Similarly, the work on WWTP 3 will include rehabilitating both secondary clarifiers and converting the tertiary filtration process.

These upgrades are crucial for improving the overall performance of the wastewater treatment facilities and ensuring compliance with environmental regulations. Trotter and Associates, Inc. is currently in the early stages of design, with construction expected to begin in early 2027.
