The Western Lake Superior Sanitary District (WLSSD) provides regional wastewater conveyance and treatment services for municipalities and industries in the Duluth, MN metropolitan area. An inspection of one its major interceptors revealed detachment of the PVC strips at the joints of the PVC-lined concrete pipe, leaving the concrete vulnerable to hydrogen sulfide corrosion. To restore the integrity of the interceptor, the WLSSD initiated a fast-track design and construction effort that included 5,300 feet of new, corrosion-resistance replacement pipe and lining of 2,000 feet of existing pipe using cured-in-place pipe. The fast-track construction schedule required the preparation of a separate pipe material purchase contract to allow pipe fabrication to begin while final design and bidding of the installation contract was completed. Bonus incentive clauses were included in both contracts to encourage the contractors to meet the project schedule. Construction was successfully completed in about 8 weeks at a cost of about 90 percent of the conceptual design budget.
