The division <br /> actively promotes efficiency and productivity improvements to keep up with <br /> their increasing infrastructure needs. <br /> <br /> ~ In the 1 st 20 years, the number of miles in the sanitary sewer line system <br /> has grow from 330 miles to 540 miles. The installation of sanitary sewers <br /> in River Road and Santa Clara over the next five years will add even more <br /> line. In reases in the number of miles and the aging of the existing system <br /> t use ualit mans ement ractices to keep the sewer <br /> mean tha staff mus q y g p <br /> collecti n system in peak operating condition. <br /> Maintena ce operator Ken Boss had an idea for a way to increase the <br /> producti ity of the combination sewer jet and vacuum. The machine is <br /> equipped to clean sewer lines using high-pressure water. The water used in <br /> the oper tion is pumped from fire hydrants and stored in a tank on the truck. <br /> The debr s tank is adjacent to the water storage tank and stores the material <br /> that is leaned from manholes, catch basins, and pump stations. Often the <br /> debris t nk has more capacity than is used in a day. Ken's idea was to <br /> convert he truck so the debris tank could carry additional water for <br /> flushing <br /> ~i <br /> <br /> I <br /> <br />
