Title
Authority to add Project 10-716-3P Wet Weather Treatment Facility, Lemont Water Reclamation Plant, to the Engineering Department Capital Improvements Program and the Capital Improvements Bond Fund, estimated cost of the project is $10,000,000.00
Body
Dear Sir:
Authority is requested to add Project 10-716-3P Wet Weather Treatment Facility, Lemont Water Reclamation Plant (WRP), to the Engineering Department Capital Improvements Program and the Capital Improvements Bond Fund.
The project consists of constructing a new wet weather treatment facility that will provide primary treatment and disinfection to flows in excess of the dry weather volume plus first flush, from the combined sewer area of the Lemont basin. The facility will be located at the Lemont WRP. In addition, modifications will be made to the existing 18-inch diameter combined sewer interceptor that enters the Lemont WRP, in order to convey the required rate of wet weather flows to the treatment facility.
The project is one component of an overall plan in response to a violation notice from the Illinois Environmental Protection Agency (IEPA) regarding discharges from outfall 002 at the Lemont WRP. The IEPA has directed the District to submit a long-term control plan to address the discharges, which the IEPA has determined are considered combined sewer overflows. This plan is a formal commitment on the part of the District, and it will present the major elements of the District’s overall plan. In addition to the subject project, this plan will include the following:
• Constructing a new pumping station and two parallel force mains to convey sewage from Lemont to an existing District interceptor sewer that is tributary to the Stickney WRP. The wastewater will receive treatment at the Stickney WRP, and the Lemont WRP will be decommissioned.
• Constructing an equalization reservoir to buffer peak wet weather flows from the separate sanitary sewer system that is tributary to the proposed pumping station.
The two additional projects will be constructed under Contracts 08-714-3P Lemont Pumping Station and Force Mains and 05-711-3P Wet Weather Reservoir. The authority to add these projects to the Engineering Department Capital Improvements Program and the Capital Improvements Bond Fund is requested under separate requests at this meeting.
The estimated cost of the project is $10,000,000.00.
Requested, Kenneth A. Kits, Director of Engineering, TEK:ECB
