The Raw Water Pump Station (RWPS) would annually withdraw 16,800 acre-feet of Tuolumne River water collected by the Infiltration Gallery which would be pumped into the Raw Water Transmission Main (also referred to as RWTM) for delivery to the Water Treatment Plant (WTP). The Infiltration Gallery, which was constructed and is owned by TID, is located four to five feet below the river bottom. The RWPS will have a design capacity of 64.6 mgd (100 cfs) and will include six vertical turbine pumps with variable-frequency drives and a 15 mgd (23.2 cfs) pumping capacity.
