Lessons Learned During Sewer Rehabilitation on Public and Private Property, City of Westlake, Ohio
Abstract:In 1992, the City of Westlake, Ohio implemented an Inflow and Infiltration (I/I) program to eliminate excessive storm water from entering their sanitary sewer system during rain events. The goal of this program was to identify the sources of excessive water, develop a rehabilitation technique or repair for the problem. Four areas were investigated and rehabilitated. Each area used some similar rehabilitation techniques, however through the course of each project, certain lessons were identified from the testing, to the bidding and finally during the construction phase. The City modified their program in the subsequent phases based on the lessons learned in each previous phase. All of the different rehabilitation methods used reduced I/I and eliminated basement flooding. The four areas and year of completion are King James Subdivision (1992), Salem-Radcliffe Subdivision (2001), Berkeley Estates (2004) and Canterbury (2007).
