Project Summary
Big Basin State Park drinking water contains excessive levels of Total Trihalomethanes (TTM) caused by the level of organic compounds in the source water. Coleman Engineering has been retained by the Department of Parks and Recreation (DPR) to provide engineering services required for the preparation of construction documents (plans, specifications, and construction estimate) for the installation of a coagulant injection and sedimentation basin system at the Water Treatment Plant to remove organic compounds from the source water.
Coleman Engineering provided preliminary engineering which involved bench-scale testing using protocol determined by DPR. Following this 50% design draft plans were produced.
The final design is anticipated to include a coagulant storage and feed system, packaged sedimentation tank, new carbon filter, associated piping, valves and controls, new roll-up door on the WTP building and, overall site improvements.
