P‐1.1.006GRS Isolation ImprovementsBackgroundThe current outlet weir on the shared wall between thegrit tanks and the grit tank effluent channel is a concretebarrier wall with a fixed height and 24 foot length. Whenplant flows are high, the water surface elevation in theeffluent channel exceeds the barrier wall height andbackflow into the out‐of‐service grit tank, which is asafety concern for workers in the grit tank. Maintenancepersonnel isolate the grit tanks at least one time per yearfor one week duration to complete planned maintenance.Personnel also isolate the tanks approximately weekly toremove rags, pieces of coating worked loose fromupstream structures and to clear the hopper and gritpump suction piping.Figure P‐1.1.006Grit Tanks Effluent ChannelDescription Provide isolation between each grit tank and the grit tank effluent channel, based onrecommendations from the study S‐1.1.006, refer to Section 4.1.1 of this E‐CAMP for additionaldiscussion.JustificationThis project is a top priority for safety reasons and would reduce the risk of inundation of staffperforming maintenance in off‐line grit tanks.Project DeliveryTraditional Design – Bid ‐ ConstructCould be combined with P‐1.1.005 (Grit and Screenings Handling Facility Modifications) orP‐1.1.008 (Grit System Rehabilitation), or P‐1.2.006 (PSB Rehabilitation)E FY2014 E‐CAMP Report 2012‐12Dec.docx 32 December 26, 2012
P‐1.1.007Vactor Receiving StationBackgroundThere is a demand for vactor/septage receiving in theEWA service area. Currently the EWPCF receives limiteddeliveries from combination (vactor) trucks at a locationadjacent to the Influent Junction Structure (IJS) as shownin Figure P‐1.1.007. The current deposition area isdesigned to be replaced in the 2012 Major Plant RehabProject which will improve the operation. It is noted thatat one time, EWA considered receiving septage at theEWPCF. Receiving septage is no longer underconsideration.Figure P‐1.1.007Vactor Receiving LocationThis project proposes to implement a receiving station tofacilitate discharge of combination truck tanks into the EWPCF. Project considerations includelocation, odor control, separation of rocks from discharge, security, sampling, control of substancesflowing to IJS, rock/debris handling. Project could be constructed in conjunction with P‐3.2.001(Waste to Energy Facilities) to achieve economies of scale in conjunction with the grease receivingstation associated with the grease to gas project.E FY2014 E‐CAMP Report 2012‐12Dec.docx 33 December 26, 2012
