BOARD/COMMISSION REVIEW:
N/A
BACKGROUND:
The Water Utilities' 2020 capital improvement plan includes rehabilitation of approximately 47 manholes, 19,538 linear feet of sanitary main/trunk sewers and 150 sewer service laterals. The primary focus of the projects is to reduce infiltration and inflow, which is leakage of groundwater and surface water into the system. The sanitary sewer main lining program is part of the Water Utilities' required IEPA CMOM (capacity, management, operation and maintenance) plan and IEPA required 10-year infiltration and inflow reduction program under Naperville's NPDES permit IL0034061.
The Water Utilities issued Bid 20-184 seeking a contractor to rehabilitate 17,538 feet of eight-inch, ten-inch, 12-inch and 15-inch diameter sanitary sewer pipeline located in the Brookdale subdivision. The contractor will use no-dig lining technology to reduce cost and disruption to the community. Sanitary sewer lining is a major component of the city's strategy to reduce system leaks associated with storm water infiltration through pipe cracks and fissures, which reduces sanitary system capacity during wet weather events. Lining the sewer provides seamless, leak-free pipes and maintains structural integrity for approximately 50 years. Reducing leaks and preserving system capacity also helps reduce the number and severity of sanitary sewer backups.
To secure the lowest possible pricing, the bid specified two competing lining technologies, glass reinforced plastic (GRP) and cured-in-place thermosetting resin pipe (CIPP).
