Pearl River CSO Storage Facility

The City of Lafayette’s approved Combined Sewer Overflow Long Term Control Plan (CSO LTCP) requires full treatment of wastewater flows and a level of control of no more than four (4) CSO overflows during a typical year.  To achieve this level of control, the recommended plan was divided into four sub-phases (Phase II-A, II-B, II-C and II-D).   The Pearl River CSO Storage Facility (Phase II-C) is required to store and convey wet weather flow to Lafayette Renew when the treatment facility has capacity, thereby improving the water quality in the Wabash River.

This Project includes the installation of 1.5 million gallons of storage that will help eliminate combined sewage from being discharged into the Wabash River during heavy rain events.  This Project will conclude the third sub-phase of the City’s Long-Term Control Plan (LTCP) leaving just the final phase to be completed.  Previous green infrastructure projects allowed for a reduction in size of this phase of the LTCP by more than 50% of the original plan that was submitted in 2009.  This Project also includes a nearly 400 kW solar field that will provide the majority of the electrical demand for the Pearl River Lift Station and was completed in July of 2022.

During 2023, Lafayette Renew began the design phase for the following projects:

• Service Area 11B Utility Extension Project – The City identified the need to provide water and wastewater services to southeast of the City limits which is currently unserved.
  
  
• Twyckenham Lift Station Elimination Project – The proposed project will eliminate the lift station by replacing it with a gravity sewer. The gravity sewer will be approximately parallel to the force main route and will connect to the Elliott Ditch Interceptor Sewer near 9th Street.
  
  
• CSO Long Term Control Plan Phase II-D – The scope of this project includes design of the following major project elements:
  • Fine Screens and Dumpster Room
  • Pump Station
  • HRT Facility
  • Electrical Building
  • Chemical Storage
  • Chemical Interconnection
  • Existing WWTP Improvements
  • Yard Piping
  • Site Work
  • SCADA
  • PRLS Expansion and Force Main
• Wastewater Master Plan Update – The City of Lafayette previously completed a sanitary sewer Master Plan in 2016.  Due to new and proposed growth and development, updates are needed for planning future capital improvements.  Phase 1 of the Masterplan Update will focus on evaluating the condition and capacity of the City’s lift stations and determining the amount of additional flow the City could accept in areas where significant development is anticipated.
