515 Little Canada Road, Little Canada, MN 55117-1600 <br />(651) 484 -2177 / FAX: (651) 484 -4538 <br />AGENDA ITEM <br />TO: Mayor Fahey and Members of the City Council <br />FROM: Joel Hanson, City Administrator <br />Greg Schroeder, Public Works Director <br />DATE: October 7, 1998 <br />RE: Vacuum/Sewer Cleaner Truck <br />MAYOR <br />Michael 1. Fahey <br />COUNCIL <br />Beverly Scalze <br />Jim LaValle <br />Steve Morelan <br />Bob Pedersen <br />ADMINISTRATOR <br />Joel R. Hanson <br />As you may know our existing 1972 jetter truck is nearing the end of its useful life and is <br />scheduled to be replaced in 1998 with a combination jetter /vacuum truck. Our jetter truck is <br />used to keep our City sewer lines clean, thus: <br />1. Reducing the potential for sewage back -up into our residents' basements, wetlands, <br />streams and lakes. <br />2. Minimizing odor complaints. <br />3. Minimizing lift station failures. <br />4. Maintaining intended flow in our system. <br />Since our 1972 jetter truck was built, the sewer cleaning industry has expanded its equipment <br />line. Trucks available today not only can clean sewer lines, but also contain vacuum systems <br />that will remove the jetted material from the bottom of the manholes without sending a person <br />down into the manhole. This not only eliminates a confined space safety issue, but also increases <br />the efficiency of removing the material at the bottom of the manhole. Besides removing material <br />for the bottom of the manhole, the vacuum system can also be used for: <br />• Cleaning ditches. (future maintenance along County Road B2) <br />• Cleaning gate valves. <br />• Storm sewer catch basin dewatering and cleaning. <br />• Keep excavation hole dry during water main repairs. <br />• Emergency lift station pumping during power outages. <br />Page 44 <br />
