DEPARTMENT: Water Utilities
SUBMITTED BY: Jim Holzapfel, Water Utilities Director
BOARD/COMMISSION REVIEW:
N/A
BACKGROUND:
The Water Utilities issued Bid 17-069 seeking a qualified contractor to provide smoke testing for approximately 195,982 linear feet of existing 6-inch through 27-inch diameter sanitary sewer pipelines in 2017. The objective of this program is to identify defects in the sanitary sewer system by filling the pipelines with smoke. If the pipeline has openings that lead to the surface or to a storm sewer, the smoke will follow that pathway and will be visible at ground level. This program is part of Naperville’s ongoing effort to identify sources of Rainfall Derived Infiltration and Inflow (RDII) in areas that experience elevated flow during wet weather events.
DISCUSSION:
The areas targeted for this project are located north and west of North Aurora Road and Raymond Drive, and include Brookdale subdivision, the Pebblewood commercial area, Frontenac industrial park and Country Lakes residences. Recent smoke testing on East Ogden Avenue and adjacent areas (Bid 16-208) identified 723 defects.
