BOARD/COMMISSION REVIEW:
N/A
BACKGROUND:
The Water Utilities 2024 Capital Improvement Plan (CIP) includes rehabilitation of approximately 50 manholes, 13,985 linear feet of sanitary main/trunk sewers, and 235 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 ten-year infiltration and inflow reduction program. These requirements are 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 December 2023, the Water Utilities issued Bid 24-014, 2024 Small Diameter Sanitary Sewer Main Lining. This bid will rehabilitate 13,985 linear feet of eight-inch through fifteen-inch diameter sanitary sewer pipeline located in Naperville Center of Commerce & Industrial Park located North Aurora Road and Diehl Road. The contractor will use no-dig lining technology to reduce costs 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).
