The Great Lakes Water Authority (GLWA) is seeking bids from construction firms to carry out extensive repair, rehabilitation, and access improvements on the Lonyo Sewer located in southwest Detroit. The project involves upgrading flow control measures, cleaning and rehabilitating the sewer, and replacing manhole frames and covers to ensure the sewer's long-term structural integrity. The sewer, originally constructed in 1919, is a large-diameter, double-barrel structure with a section beneath rail lines, and it currently contains significant debris and defects due to its age. The work is part of GLWA’s ongoing maintenance efforts, which include inspections and repairs based on detailed assessments such as historical reviews and multi-sensor inspections. The project spans from the intersection of Lonyo and Kirkwood Streets to the Baby Creek CSO Facility in Patton Park, with flow from multiple upstream sewer lines terminating at this point. The scope includes not only sewer rehabilitation but also the installation of flow control and access features to facilitate future maintenance activities. The contract, titled "Lonyo Sewer Rehabilitation," has a projected value between five and fifteen million dollars, with a response deadline of May 15, 2025. This initiative aims to address existing defects, remove accumulated debris, and improve the sewer’s capacity and operational reliability, supporting GLWA’s broader infrastructure and environmental management objectives.

The Great Lakes Water Authority (GLWA) requests bids from construction companies ("Contractor) to provide repair work and flow control and access improvements for the GLWA Lonyo Sewer in accordance with the attached Specifications and PlansDrawings. The repair work site is located in southwest Detroit, beginning at the intersection of Lonyo Street and Kirkwood Street and terminating at the GLWA Baby Creek Combined Sewer Overflow (CSO) Facility in Patton Park. The proposed Work for the sewer is expected to consist of access and flow control improvements to facilitate the Work in the sewer, rehabilitation and cleaning of the sewer itself, and manhole frame and cover replacements. As part of GLWA’s ongoing maintenance and operation plans, various sewers were selected by GLWA to be inspected and repaired to ensure long-term structural integrity. Historical document review, manual entry inspections, and multi-sensor inspections (MSI) were completed on the Lonyo Sewer. Based on the above inspections, a rehabilitation plan was formulated for to complete structural and operation and maintenance (O&M) repairs throughout the full length of the Lonyo Sewer. Included in this plan is the addition of various flow control and access improvements to facilitate the repair work for both this and future maintenance work. The Lonyo Sewer is a large-diameter, double-barrel structure dating back to 1919. The barrels range in size from 14.5ft by 14.5ft to 14.5ft by 17.5ft. There is a triple-barrel depressed section running beneath existing rail lines that measures approximately 11.5ft to 13.5ft in diameter. Defects are present throughout the sewer consistent with the age of the structure and are included in the design drawings. Of a particular note, the Lonyo Sewer contains a significant amount of settled debris, with large amounts of debris present in both the triple-barrel section as well as in Patton Park. At its upstream end, the Lonyo Sewer conveys flow from the Wyoming Sewer, the Wyoming Relief Sewer, and the Wetherby Sewer. Additional smaller connections are present throughout the length of the sewer. At the downstream end, the Lonyo Sewer terminates at the Baby Creek CSO Facility, from which flow is either conveyed to the Water Resource Recovery Facility (WRRF) or to the Baby Creek Outfall in wet weather events of sufficient size.
