Over the past few years, the wastewater collection system serving the Hickory Grove area has shown signs of increasing problems with infiltration and inflow, known as I&I. I&I problems occur when individual lines that connect to larger collector lines begin to allow increasing volumes of storm water and groundwater into the collection system. As an initial step in locating specific points of infiltration, ONWASA will do smoke testing to determine entry points most in need of attention. The smoke is non-toxic, noninvasive of homes and business, and is confined to the collection system.
ONWASA recommends that customers in Hickory Grove run water in every sink in the morning of September 28th to ensure drain traps are full so no smoke will enter your home. If smoke exits through the roof vent, everything is working properly. ONWASA employees will be on-site during testing to answer questions.
If there are any questions or concerns, we encourage our customers to call our Operations Center at 455-0722.
