mains that are most susceptible to root intrusion and, therefore, need more frequent <br /> cleaning (every 3 years). Finally, the third category contains the larger mains that due to <br /> heavier flows are generally self-cleaning and, therefore, are cleaned on an as needed <br /> basis. <br /> Following this draft policy the Public Works crew will need to clean approximately 10 or <br /> 11 miles of sewer main annually; six miles of clay mains and four to five miles of plastic <br /> and/or lined clay mains. Manholes would be inspected as sewer mains are cleaned. <br /> Finally, the 14 lift stations will continue to receive an annual cleaning and mechanical <br /> check. <br /> On a related matter, Council had previously asked the cost of adding the Omni Site to the <br /> remaining seven lift stations so they could be monitored directly from a computer. <br /> Attached is a quote from Electric Pump Company for $22,050 ($3,150 per lift station) to <br /> install the Omni Site system at the remaining seven lift stations. <br /> Council Action Requested <br /> Discuss the draft Sanitary Sewer Maintenance Policy and provide direction on any <br /> changes the Council would like included. Also, consider the quote for the seven Omni <br /> Site installations and give staff direction whether or not to proceed at this time. <br /> City Council Meeting <br /> C:\Users\sonja.klingberg\Desktop\9-17-12 SewerMaintenancePolicyMemo.doc <br /> Page 2 of 2 <br />
