RE: Requisition No. REQ-0004588
CSO Outfall Rehabilitation Phase VI
Vendor: Inland Waters Pollution Control, Inc.
Status: New Contract/PO
MOTION
Upon recommendation of Navid Mehram, Chief Operating Officer - Wastewater Operating Services, the Board of Directors (Board) of the Great Lakes Water Authority (GLWA), authorizes the Chief Executive Officer (CEO) to enter into Requisition No. REQ-0004588, “CSO Outfall Rehabilitation Phase VI” with Inland Waters Pollution Control, Inc., at a cost not to exceed $7,589,015.00 for a duration of 760 days; and authorizes the CEO to take such other action as may be necessary to accomplish the intent of this vote.
BACKGROUND
Outfalls are part of GLWA’s wastewater infrastructure and function as the interface between collector and interceptor sewers. They redirect dry weather flow to the Water Resource Recovery Facility (WRRF) while allowing relief of wet weather flows to the nearby river. GLWA has been proactively working to maintain and repair these facilities. Over the past few years, GLWA has completed rehabilitation of over two (2) dozen outfalls in four (4) project phases and will complete Combined Sewer Overflow (CSO) Outfall Rehabilitation Phase No. V by the end of 2025, rehabilitating another 13 outfalls. The proposed project, CSO Outfall Rehabilitation Phase No. VI, will rehabilitate 19 additional outfalls. These structures are generally located near the Northwest Interceptor alignment from Carbon Street to Berg Road, and discharge into the Rouge River. Constructed between the early to mid-1900s and modified several times since construction, these assets have deteriorated over time.
JUSTIFICATION
Inspections under GLWA Contract No. 2003443 identified several defects at each outfall. The defects were classified and graded per the National Association of Sewer Service Companies Pipeline Assessment Certification Program, resulting in structural and operational and maintenance defects graded on a scale of one to five (with five being most severe). This project addresses defects graded three to five only, through a variety of in-sewer repairs along with debris removal. It should be noted that eight (8) locations will require extensive rehabilitation, including cured-in-place-pipe lining, replacement of the existing pipe and associated underground structures, and stone rip-rap placement near and within the Rouge River. Rehabilitation of the outfalls will extend the service lives and improve the reliability of these assets. Additionally, this contract proposes safety improvements to access manholes, including access entrance up-sizing, installation of larger and hinged frames and covers, and new steps. This work is proposed under construction Contract No. 2300149 and CIP No. 260510.
