<br />City of Arden Hills <br />Public Works Department <br />Sewer Utility <br /> <br />SMOKE TESTING NOTICE <br />Inflow and Infiltration (III) Study <br /> <br />In October, contractors working for the Arden Hills Public Works Department will <br />be conducting smoke tests of the sanitary sewer system in your area. Smoke <br />testing is a standard means of identifying sewer defects and rain water cross <br />connections. <br /> <br />The purpose of these tests is to find defects and faulty connections where excess <br />ground and rain water can enter the sanitary sewer system, negatively effecting <br />its economical and safe functioning. This smoke testing work is part of Public <br />Works Sewer Utility's Infiltration (1/1) Study that began in 2007. <br /> <br />The information gained from smoke testing will help the City prepare a <br />comprehensive plan to reduce rain water Inflow and ground water Infiltration (1/1) <br />in its sanitary sewer system. Reducing 1/1 is an ongoing citywide effort to: hold <br />down wastewater treatment costs that are passed on to the user; to help protect <br />the integrity of the sewer system; and to be in compliance with the Metropolitan <br />Council's Environmental Services (MCES) Surcharge Program adopted by the <br />Metropolitan Council in February of 2006. <br /> <br />
