Water Supply Pipeline and Sanitary Sewer Design Report, Queensland

This report details the design of a water supply pipeline and sanitary sewer system for a town in Queensland. It begins with population projections and water demand calculations, considering factors like domestic, unaccounted for, institutional, and fire demands. The water supply pipeline design utilizes the Hardy-Cross method to analyze flow, velocity, and head-losses, with PVC pipes and the Hazen-Williams equation. The sanitary sewer design covers the design of the sewer line, including peak factor calculation, average flow calculation, and pipe selection. The report also includes discussions on self-cleansing velocity, septicity, and the selection of uPVC pipes. The design incorporates invert levels and gradient calculations to ensure efficient and sustainable operation of the system.
