Burris Pump Station Phase 2 <br />Anaheim, California <br />Project Highlights: <br />• 200 CFS pump station <br />capacity <br />• Circular wet well <br />requiring CFD <br />computer model and <br />scale model of the wet <br />well <br />Schedule: <br />2014 — 2016 <br />Reference: <br />Orange County Water <br />District <br />18700 Ward Street <br />Fountain Valley, CA <br />92708 <br />Chris Olsen, PE <br />714/378-3232 <br />Orange County Water District (OCWD) has been operating the existing Burris Pit Pump Station for <br />over 20 years. However, due to the design of the existing pump station, the District has not been able <br />to properly maintain or replace the existing pumps and motors. The District has elected to completely <br />replace the existing pump station. The project will construct as much of the facility as possible without <br />disrupting the use of the existing pump station and basin with the intent of meeting the District's goal <br />of "No Water to the Ocean." The proposed pump station consists of four 1,750 horsepower vertical <br />turbine pumps delivering a maximum flow rate of 200 cfs to the Santiago Basins from the Burris Basin <br />a 55 foot diameter by 50 foot high wet well, trash rack, dual 96-inch intake pipelines and a 108,000 <br />gallon surge suppression system. This flowrate is critical to OCWD operations particularly during the <br />winter months. Once the new facility is ready, the old pump station will be taken out of service, any <br />useful equipment salvaged, the building demolished and the new pump station tied into the existing <br />pipeline. <br />Burris Pump Station Phase 1 constructed an earthen berm within the existing Burris Pit to surround <br />the proposed wet well, trash rack and intake pipelines to be constructed during Phase 2. Thus, <br />allowing OCWD to operate the basin during construction of new pump station. Over 190,000 cubic <br />yards of on -site material was moved to complete Phase 1 in November 2013 and the basin was in <br />operation for the 2013-2014 storm season. Phase 2 began in September 2014 and as of February the <br />wet well is 50% complete. Phase 2 is expected to be completed in October 2016. <br />The Burris Pump Station Project, Phase 1 was awarded the ASCE, Orange County, California <br />Branch, Flood Management Project of the Year, 2014. <br />TETRA TECH <br />
