Document Description
The Tuolumne Utilities District (TUD) proposes the Matelot Pipeline and Turbidity Station Project (Project), which includes constructing an 18-inch diameter raw water main up to 1,650 feet in length that would convey water from Matelot Reservoir in the north to the Columbia Water Treatment Plant in the south. The proposed pipeline would generally mn parallel to the existing open channel Matelot Ditch and would carry a portion of the water that currently runs in the open ditch. The existing Mate lot Ditch would still carry water flow, but at a reduced flow rate. The Project also includes constructing a turbidity station at the northern terminus of the Phase 2 alignment where the Columbia Ditch discharges flows to Matelot Reservoir and the existing Matelot Ditch. The turbidity station would consist of a small building (48 square feet) constructed on a cement slab foundation and associated interior and exterior sampling, power supply, and control equipment, including small diameter conduit, sampling supply and drain lines, pumps and valves, and a reservoir level box.
