BACKGROUND
GLWA operates nine (9) Combined Sewer Overflow (CSO) Facilities. The CSO facilities provide preliminary treatment and disinfection during wet weather. Some facilities provide additional settling. To prepare these CSO facilities for their full utilization, the “CSO Facilities Assessment Report” prepared under GLWA Contract No. CS-299 identified a series of repairs and enhancements that are recommended to improve facility reliability, efficiency, flexibility, operation, maintenance, and safety.
This project is to address the following recommendations: upgrade the disinfection and screening system at St. Aubin, install controls upgrades at Baby Creek and Belle Isle, implement safety improvements, and perform architectural rehabilitation at all nine (9) CSO facilities. The project is approved for the State Revolving Fund.
JUSTIFICATION
This construction project will implement the improvement required to achieve several of the goals included in the “CSO Facilities Assessment Report”. Namely, those goals are to upgrade the disinfection and screening systems at St. Aubin, install controls upgrades at the Baby Creek and Belle Isle Facilities, and implement safety improvements and architectural rehabilitation at all nine (9) CSO facilities. This project is integral to ensuring the long-term safety, architectural integrity, and adherence to National Pollutant Discharge Elimination System permit requirements at the aforementioned CSO facilities.
