ADOPTED BY THE CITY COUNCIL OF THE CITY OF ARDEN HILLS THIS 8TH DAY OF OCTOBER, 2012 <br /> <br /> <br /> <br /> <br /> <br />Schedule – The City’s goal is to inspect and maintain the components of its sanitary <br />sewer system according to the attached schedule. <br /> <br />Equipment – The equipment used to perform maintenance will depend upon the <br />equipment available and its effectiveness as determined by qualified staff. <br /> <br />Television Inspection – The City’s sanitary sewer mains will be inspected by <br />television camera in accordance with the attached schedule. Any sewer mains located <br />on a street where a street maintenance project is planned will be inspected before and <br />after such a project. Sanitary sewer mains in a new development must be televised <br />before said mains are turned over to the City. Television inspection may also be used <br />to inspect the system where there are possible problems. In addition, the City may <br />require any main near a construction site to be televised before and after the <br />construction (i.e., near blasting, digging, other activities that might disrupt the main, <br />etc.) <br /> <br />Visual recordings of sewer main televising will be required of any vendor performing <br />this service for the City. A written report summarizing and interpreting the findings <br />of the televising will also be required. These records will be kept by the City for a <br />minimum of 12 years. <br /> <br />B. Maintenance Category <br /> <br />The sanitary sewer mains and facilities identified as Category 1 will receive ordinary <br />routine maintenance as noted on sewer maps. The sanitary sewer mains and facilities <br />identified on the sewer map as Category 2 will receive more frequent maintenance <br />and those identified as Category 3 will receive less frequent maintenance. When a <br />sewer main or facility is identified as anything other than Category 1, the reasons why <br />maintenance is needed on a different schedule will be documented. Sewer mains and <br />facilities will receive maintenance according to the attached schedule. <br /> <br />The Public Works Director will determine whether a main or facility is Category 1, <br />receiving routine sewer maintenance, Category 2, receiving more frequent <br />maintenance or Category 3, receiving less frequent maintenance. Based on periodic <br />assessment, maintenance will be adjusted and a sewer main may be moved from one <br />category to another. <br /> <br />C. Sanitary Sewer Lift Stations <br /> <br />The City maintains lift stations using specific maintenance that is reasonable and <br />recommended. The number of lift stations, location, date of installation, and capacity <br />of each lift station is kept on record. Maintenance for each lift station is reflected in <br />the following list of activities: <br /> <br /> Easy availability of original manuals with manufacturers’ recommended <br />maintenance schedules for all lift station equipment <br /> Operating procedures for manipulating pump operations (manually or <br />automatically) during wet weather to increase in-line storage of wet weather flows
