The Scope of Services defines the extent of the Design Professional and the services to complete the work and documents specified herein for Design (Plans, Specifications & Estimate), assistance during the bidding and award stage, Construction Support, and As-built generation of “Cielo and Woodman Pump Station”, herein referred to as “Project”. This project was brought about due to the Cielo and Woodman Pump Station facility deteriorating and needing replacement. Built in 1961, the Cielo & Woodman Pump Station is an underground facility and serves the southern tier of the Paradise Mesa 610 HGL Zone. This pump station is located at 6599 Cielo Drive, San Diego CA 92114 at the southwest corner of Cielo Dr and Woodman St. The pump station is equipped with one constant speed pump rated at 2000 gpm with a 75 hp motor. The Cielo & Woodman Pump Station works in conjunction with the Paradise Mesa Standpipe and three pressure regulating stations which are fed by San Diego County Water Authority connection SD#19. Per the Alvarado Water Treatment Plant (WTP) Service Area Master Plan: Paradise Mesa Focus Area Report, the new Cielo and Woodman Pump Station will be the primary feed to the Paradise Mesa 610 Zone and will work in conjunction with the Paradise Mesa Standpipe. The existing Paradise Mesa #1 Pump Station will be demolished and the Paradise Mesa #2 Pump Station will remain as the backup pump station to the 610 Zone. The San Diego County Water Authority Connection #19 will be kept as a backup to the new pump station. The pump station facility will be designed to handle a minimum of 7.70 MGD (5,345 gpm), which is equal to 2020 CDM plus 833 gpm commercial fire flow.. All the pumps in the station shall be designed to be able to switch to VFDs, shall be sized to work efficiently on both 536 HGL and 490 HGL Zones, and shall follow a first-in, first-out (FIFO) sequence. The dual suction to the pump will be connected to the new 48-inch Otay 2nd Pipeline via a 30-inch manifold. The discharge to the pump station will be connected to the new main along Cielo Dr.
