The sanitary trunk sewer was largely <br />constructed in the 1960's and early 1970's using (predominately) clay pipe. The use of <br />clay pipe during this time was the industry standard, but more watertight pipe products <br />PVC) have been developed and replaced clay pipe which became the new industry <br />standard the last few decades. Leaky clay pipes incur unnecessary Met Council treatment <br />costs due to infiltration of ground water into the trunk sewer. <br />Public Works has an inspection and maintenance program for the municipal sanitary <br />sewer system. This program includes inspecting the trunk sewer by televising and <br />evaluating the condition of the pipes. Defects are noted/documented while performing <br />inspections, including cracks in the pipe and leaking joints. <br />A priority list that ranks the segments of pipe requiring repair or remediation is maintained <br />by Public Works. A map of the 2021 sanitary sewer rehabilitation priorities is attached <br />Attachment A) <br />Public Works in conjunction with Stantec has prepared plans and specifications (bid <br />documents) in house for use in obtaining public bids for the sanitary rehabilitation <br />project, City Project 2021-005.
