BOARD/COMMISSION REVIEW:
N/A
BACKGROUND:
The Water Utilities' 2023 Capital Improvement Plan (CIP) includes rehabilitation of approximately 42 manholes, 15,394 linear feet of sanitary main/trunk sewers, and 169 sewer service laterals. The primary focus of these projects is to reduce leakage of groundwater and surface water into the system. The sanitary sewer main lining program is part of the Water Utilities' Illinois Environmental Protection Agency (IEPA) required capacity, management, operation, and maintenance (CMOM) plan and IEPA required ten-year infiltration and inflow reduction program under Naperville's National Pollutant Discharge Elimination System permit IL0034061.
Sanitary sewer lining is a major component of the city's strategy to reduce system leaks associated with stormwater 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 help reduce the number and severity of sanitary sewer backups.
DISCUSSION:
In March 2023, the City issued Bid 23-014, 2023 Small Diameter Sanitary Sewer Main Lining. This bid will rehabilitate 11,591 linear feet of eight-inch diameter sanitary sewer pipeline located in the Fairway of Country Lakes and Pebblewood subdivisions. The contractor will use no-dig lining technology to reduce cost and disruption to the community.
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).
