The station was laid out so that there should be adequate working space for maintenance <br /> of the pumps and equipment, and general operation of the pump station. <br /> Puma Station Piping <br /> The pump station piping was laid out as shown on the drawing. The base plates <br /> for the pumps would be mounted on structural steel beams over the intake sump, and <br /> would be positioned as shown on the drawing. Accommodations have been made for an <br /> additional lower capacity pump to be added in the future if desired. The majority of the <br /> piping connections would be made with Victaulic style couplings. Welded steel fittings are <br /> shown at the discharge side of the station to save room, and a few flange connections will <br /> also be required. A drain valve would be located on the discharge pipeline, as well as an <br /> access port for cleaning the pipeline with a high-pressure jet-wash system. An air chamber <br /> system has also been included in this preliminary design to limit the surge pressure <br /> fluctuations in the piping that will result from sudden changes in discharge velocities. <br /> Additional analysis of the surge suppression system will be required during the final design <br /> phase of this project. <br /> Electrical <br /> The electrical components of the new pump station are described in the following <br /> section prepared by Morroni Engineering who performed the preliminary design of the <br /> electrical system for this project. <br /> 11 <br />
