GSD Sewer Interceptor Lining

Galesburg Sanitary District invited HEI to provide preliminary and construction engineering services including the preparation of plans, specifications, estimates and full construction oversight for the lining of 2500' of sewer interceptor. The existing brick interceptor varied in size and shape from 42"-48" round to more rectangular shapes of equivalent area. HEI utilized a cured-in-place lining system to rehabilitate the sewer. This project was complicated by the 4-5 million gallons of flow that would need to be bypass pumped during cleaning and lining operations and by the location of the interceptor being under the floor of a large concrete storm water channel.
