BACKGROUND:
The objective of the smoke testing program is to identify defects in the sanitary sewer system. Smoke testing is a relatively simple process consisting of blowing smoke mixed with large volumes of air into the sanitary sewer lines, usually induced through the manholes. The smoke travels the path of least resistance and quickly shows in areas that allow surface water to inflow into the sanitary sewer system. The smoke will identify broken manholes and improper connections, including roof drains, sump pumps, storm sewer connections, yard drains, uncapped lateral lines and even will show cracked mains and laterals. If the pipeline has openings leading to the surface or a storm sewer, the smoke will follow the pathway and 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 experiencing elevated flow during wet weather events.
In March 2022, the Water Utilities issued Bid 22-012 seeking a qualified contractor to provide smoke testing of approximately 153,821 linear feet of existing 6-48-inch diameter sanitary sewer pipelines.
DISCUSSION:
The areas targeted for the project are West Highlands, Moser Highlands, Maplebrook, Hunters Woods, University Heights and Naper Carriage Hill subdivisions. The sanitary sewer smoke testing program is part of the Water Utilities IEPA required 10-year infiltration and inflow reduction program.
