The City of Carbondale hired BG Consultants to evaluate their entire sanitary sewer collection system and make infrastructure improvement recommendations. The City’s goal was to structurally reinstate the sewer mains and manholes while reducing the potential for rainfall derived inflow and infiltration (RDII). BG’s team performed a review of existing system documents and on-site, CCTV, and manhole inspections. Our findings were used to conduct a CCTV evaluation and develop a system-wide improvements project.
The City opted for a single-phase project due to benefits involved with the USDA Rural Development, CDBG Block Grant Program, and KDHE interim financing. The total rehabilitation project includes 92 point repairs, 60 service tap repairs, 26,600 feet of CIPP pipe lining, a 100-foot cased railroad bore, and the structural rehabilitation of 140 manholes.
Multiple city council work sessions and town hall meetings were held to discuss the findings of the inventory efforts and the required rehabilitation actions. BG’s team worked hand in hand with City staff to develop a project that meets their needs within the determined budget. Construction is expected to be completed in June 2016.
