Document Description
IRWD, as the largest percentage owner (48%), proposes to buy the capacity allocation and ownership from the other owners and convert the reservoir to non-potable water storage to allow IRWD to maximize the use of reclaimed water through additional seasonal storage. Major design components required to convert the San Juaquin Reservoir include: (1) Modifications to the reservoir for repairs; (2) Construction and operation of three pump stations, one at the reservoir and two offsite; (3) Construction of a one-half million gallon storage tank to be buried at the reservoir; (4) Construction of approximately one mile of reclaimed water pipeline; and (5) Construction of a chlorination facility at the reservoir. Construction of the proposed project is anticipated begin in late 2000 and to be completed by mid-2003.
