2006 Water Comprehensive Plan - City of Bellevue

HYDRAULIC OPERATIONSTables 6-7 through 6-9 summarize the hydraulic operation of the Bellevue system. Administrativeoperations and specific operation and maintenance programs are discussed in Chapter 9.Hydraulic operations are summarized for each of Bellevue’s three major operating areas: EastBellevue operating area, West Bellevue Operating Area, and South Bellevue Operating Area.Figure 6-3 show the locations of each pressure zone. The tables are arranged by major operatingarea. An operating area consists of those pressure zones that use common reservoirs forequalizing and emergency storage. The individual pressure zones associated with each of thesemajor areas are summarized in each Table separately. The Tables include, primary supplyconnections, reservoirs and PRV’s serving each pressure zone.ZoneLake Hills 520*Lake Hills 520 CrossroadsArea*Table 6-7East Bellevue Operating Area Pressure ZonesPrimary SupplyConnections Reservoirs Zone served by PRV's50 (emergency)137 (emergency)NE 40th Inlet,NE 8th inlet,SE 28th Inlet,161st Street Inlet,NE 40th,Lake Hills,Newport,Parksite,Eastgate InletKirkland's 545Redmond 400 Served directly from the 520 zone073, 082, 041Redmond 330 Served from the 520 zone through Redmond 400 zone 139, 140Kelsey Creek 450 Relies on 520 zone for storage042, 093, 044, 094Lake Hills 435 Served directly from the 520 zone081, 070, 080Lake Hills 380 Served directly from the 520 zone067, 069Sammamish 270 North* Main supply from 520 via Sammamish 065, 061, 072, 071, 068, 114Sammamish 270 Central*Sammamish 270 South*the Eastgate 370 zonethrough PRV 065Eastgate 440 Served directly from the 520 zone059, 060, 066Eastgate 400 Served directly from the 520 zone095, 101Eastgate 370 Served directly from the 520 zone130Eastgate 300 Served from the 520 zone through Eastgate 440 zone 058Sunset Hills 450 Served directly from the 520 zone041College Hill 440 Served directly from the 520 zone039, 136College Hill 380 Served from the 520 zone through College Hill 440 037, 038, 154, 098zone* Lake Hills 520 and Sammamish 270 Pressure Zones cover large areas where typical pressure ranges vary andthus were separated into geographical areas .6-22
