Grafton Wastewater System Improvements Project

The proposed project will consist of the separation of existing combined sewer infrastructure with a separated sanitary sewer system and upgraded storm sewer system, reducing CSO discharges as defined in the City's permit requirements. The project proposes a sewer system separation project consisting of the replacement /upgrade of approximately 17,500 LF of 8" and 12" sanitary sewer lines, approximately 9,000 LF of 12" storm sewer, 117 EA Sanitary Manholes, 66 EA Storm Drain Connections, 1 EA Valve Repair and other necessary appurtenances. Separating the sanitary and storm sewer collection system will minimize the amount of I&I in those areas selected for construction, which will reduce wet weather flow to the plant significantly.
