Locust Gap Inflow and Infiltration Study

Mount Carmel Township proposes to use a recently approved Community Development Block Grant to conduct an inflow and infiltration study of the Locust Gap sanitary sewer system.

The selected engineering firm will manage and analyze a sewer televising and rehabilitation study of the Locust Gap sewer system, which consists of approximately 15 miles of mainline from the Locust Gap pump station into the village system of approximately 160 EDUs. The engineer's services would entail the bidding and procurement of services of a televising contract and management of the closed-circuit televising (CCTV) phase, including on-site visits by the engineer to address any issues that arise in the field. The engineer will review the CCTV recordings and inspection reports; complete a detailed technical summary of the CCTV operations to include identifying areas of needed repairs and recommending potential rehabilitation and/or replacement of infrastructure; prepare a mapping exhibit that identifies sewer mains/laterals/manholes that require rehabilitation or replacement; prepare a detailed engineer's opinion of the probable cost associated with recommended rehabilitation and/or replacement, and prepare a technical memorandum with recommendations for sewer rehabilitation and/or replacement.

The engineer will then put a project out to bid to complete the necessary manhole and sewer mainlining. The engineer's estimate lists a conservative number of $47,000 to complete the lining work. Additional CDBG funding may be available if needed.

Work is expected to be completed by the summer of 2022.
