This document is a drawing attachment for RFQ 140R3026Q0044 concerning a Domestic Water Treatment System Replacement project. The drawing provides a technical schematic for an EPD (Domestic Water Treatment) drinking water filtration system located at Parker Dam, California.

The flow diagram illustrates a dual filter bank system (Filter Bank-A and Filter Bank-B), each containing two stages of filtration. The system includes raw water input from pumps, isolation valves, a crushing mechanism, four numbered filter units per bank, pre-adjusted pressure regulators set to 340 SPSI, drainage systems directing to waste, and connections to domestic water and effluent surge tanks. The diagram incorporates a valve sequence chart indicating operational conditions and valve positions (open, closed, isolated, etc.) across multiple operational modes labeled A through J. A detailed valve symbols legend identifies filter discharge valves, backwash valves, priority valves, and turret outlet valves. The media specifications table indicates two tank configurations with corresponding media depths. Supporting annotations reference KWT Systems as the equipment supplier and provide technical documentation reference numbers. The schematic serves as a technical specification for equipment replacement requirements and system configuration.
