" C: ,., ..) J.e..:;;.; (,(, ~1 E THO r 0 L J T ,\ N W A T to: I{ )) 1ST Hie T Verdes feeder, and the Santa Monica feeder. It traverses the City of Pasadena under Mountain Street and can deliver water through a short connection directly into Pasadena's Sunset reservoir. The Orange County feeder will deliver water to the cities of Fullerton, Anaheim, and Santa Ana, The point of diversion is at the water softening and filtration plant turnout so that water can be taken from the upper feeder either on the upctre:lI1\ 01' the downstream side of the plant, In this way raw water can be sup- plied for irrigation needs or softened and filtered water for domestic and industrial use as required. The amount of water released into this feeder will be controlled by manually operated throttling valves, the operator 'being guided by a flow indicator on the venturi meter at the beginning of the feeder. This feeder was designed for an unobstructed flow of 55 c.f.s. for a length of about 15 miles, At the end of this section the water will be, dischargcd into, or can be by-passed aronnd, an equalizing reservoir at hydraulic grade. The remainder of the feeder below the reservoir was designed as a conventional delivery line and will be subjected to a full reservoir pressure at the time of no demand, with correspondingly 'lower prcssures at the time of withdrawals. Provision was made in de- signing this feeder for extending the delivery of Colorana rtiver water to the south coastal cities of Orange County, The Palos Verdes feeder will deliver water to the cities of Los Angeles, Compton, Torrance, and Long Beach. It will also receive the excess water dispatched from Lake Mathews and noL taken by the cities supplied from the Santa Monica feeder. This excess water will flow to the Palos Verdes reservoir at the end of the line to be stored there until delivered by backflow to the member cities named above. This feeder was designed for a maximum graded flow, starting with 210 c.f.s. at the Eagle Rock Canyon turnout structure and discharging 60 c.f.s, into the Palos Verdes reservoir, Propel' allowance was made for the rise of static pressure and for water hammer which may be caused by the closing of sectionalizing valves located about every five miles along the thirty-one miles of this feeder. The automatic pressure control valves operating this sys- tem were designed to pass all the water unless there was some deficiency in the supply coming from Lake Mathews. In the latter case these valves would automatically throttle or close and the supply for the lower areas of Los Angeles, Compton, Torrance, and Long Beach would come by backflow from the Palos Verdes reservoir.
