This document outlines the key components and processes in a water treatment plant and water distribution system. It discusses intake of raw water from rivers or reservoirs, followed by screening, aeration, sedimentation, filtration, disinfection, and storage before distribution. It also lists different types of pipes, pipe joints, valves, distribution methods, reservoirs, and distribution system layouts used in conveying and supplying treated water.
