Resolution to Appropriate Funds and Approve the Purchase of a Combination Sewer Truck from Jack Doheny Supplies, Inc. ($398,806.00) (8 Votes Required)
Memorandum
The attached resolution authorizes the purchase of a Vactor model 2115-PLUS combination sewer unit mounted on a 2012 Kenworth model T400 chassis from Jack Doheny Supplies, Inc. for a total purchase price of $398,806.00. A combination sewer truck is a piece of equipment that combines high pressure jetted water and vacuum removal to clean sewers. Additionally, the vacuum portion of the vehicle is used to hydro-excavate, which means to use vacuum along with pressurized water to remove soil. Hydro excavation is the safest way to dig around underground cables, curb boxes, and pipes because it removes the soil without damaging the underground structures. Combination sewer trucks are routinely used in the maintenance of sanitary and storm water systems. Additionally, the vacuum portion of the vehicle is frequently used to control water in an excavation during the repair of a water main break.
Currently, we have three Vactor brand combination sewer trucks. This truck will replace a 2004 unit with 8060 hours of use. Over the last two years, this unit has been taken to Fleet Service for maintenance and repairs 53 times of which 58% have been for breakdowns. These breakdowns have taken the unit out of service from as little as four hours to as long as two weeks.
The loss of production caused by these frequently breakdowns makes it impossible to stay current on the scheduled preventive maintenance program of our underground utilities. Cleaning of the sanitary sewer system is programmed or scheduled based on the operational history of a segment of the system. A particular portion of the system or specific pipe is periodically cleaned, with the cleaning period being set at an interval shorter than historical time between backups. Failure to meet the cleaning schedule puts the system at risk for clogging...
