Thomas & Hutton provided smoke testing, video inventory, opinions of cost, prioritizing of repairs, and design for the rehabilitation of clay sewers for the City of Dublin’s Downtown Sewer Rehabilitation Project. The City entered into an agreement with the Georgia Environmental Protection Division to reduce impacts from inflow and infiltration in the sewer system. Thomas & Hutton was charged with the inspection of 144 manholes, the review of video for 48,000 linear feet of gravity sewer main, the coordination of smoke and dye testing to determine cross-connections, and preparation of construction documents for the repair and rehabilitation of the manholes and the sewers.
Thomas & Hutton assisted the City in loan/grant writing to place the project on the GEFA/SRF Priority Fundable Project List for American Recovery and Reinvestment Act funding. Thomas & Hutton was successful in the pursuit of a categorical exclusion for the project. Thomas & Hutton prepared a GIS database for the City of Dublin, which linked the sewer infrastructure mapping to “before” and “after” manhole photographs, sewer video inventory, and proposed rehabilitation recommendations to assist the City in long range planning and maintenance budgeting.
