Village of Monticello Sewer Smoke Testing
Scheduled to take place between May 11th and May 29th
May 14, 2020
Delta 3 Engineering will be conducting smoke testing of the sanitary sewer system as a means of located defects in sanitary sewer mains and service laterals that allow rainfall runoff or ground water to enter the sanitary sewer collection system. Locating and correcting these defects helps conserve the available capacity of the wastewater collection system, lift stations and wastewater treatment facility. Smoke testing is done by introducing non-toxic smoke, along with large volumes of air, through an open sanitary sewer manhole. Smoke will appear around nearby manhole lids and from the ground above defects in sanitary sewer mains and sewer laterals. Smoke will also appear where there are cross connections to the storm sewer system.
Caution to property owners: Water can evaporate from unused plumbing fixtures or P-traps that would otherwise prevent sewer gases from entering the building. If you have a bathroom, plumbing fixture or basement floor drain that is seldom used, refill P-traps by running water into the fixtures before smoke testing is to begin, and on a routine basis thereafter in order to prevent sewer gas from entering the building. Smoke coming out of plumbing vent roof stacks is completely normal and is not a cause for alarm. If the plumbing system of your residence or business is adequate and all drain traps are full of water, smoke should not be seen indoors. Smoke observed indoors during the testing would indicate that a plumbing deficiency is allowing unpleasant and potentially hazardous gases from the sanitary sewer system to enter the building. Should smoke enter your home or business, you may contact a member of the smoke testing crew working in your area. The crew member will be able to help verify where the smoke has entered your building. Deficiencies located on private property will be located and identified.
The information gained from this testing will be used to improve your sanitary sewer service and could reduce the future cost to utility customers. If you have any questions, comments or concerns, please feel free to contact Mr. Kevin Komprood, Village of Monticello Director of Public Works, at (608) 938-4383.
