Mr. Zensius was responsible for a fast -track, $5.3M <br />design -build project for a 3.6-mg capacity, welded steel water storage tank, a <br />dedicated booster pump station with five 150-hp pumps, piping, and standby <br />on -site electrical generation. Site improvements, along with water distribution <br />system improvements necessary to complete the tank and booster pump <br />station, are included.

Mr. Zensius was responsible for the design of two new <br />municipal wells located in city parks. The wells will be designed to produce <br />between 1,000-1,500 gpm of high -quality water with minimal aesthetic impacts <br />to the surrounding established neighborhoods. The wells will be designed to <br />provide arsenic treatment. However, if water quality is such that treatment is <br />not currently needed, piping, valves, and well site space will be provided for <br />future installation if needed due to changes in regulations or water quality. <br />Both well sites will have buildings constructed to house the well, pump motor, <br />sodium hypochlorite feed system, instrumentation, controls and electrical <br />equipment. As a part of this project, five existing wells that are no longer in <br />V 5 use will be destroyed. <br />
