This document presents the design of a sewerage system for the Bannu campus of UET Peshawar. A group of three students supervised by Dr. Afed Ullah Khan designed the system. The document outlines the population data and flow calculations for sanitary sewage and storm runoff. It then details the requirements for the combined sewer design such as pipe sizes, slopes, depths, and manhole spacing. Calculations are shown for the total estimated sewage flow of 3,648 cubic meters per day. The design aims to properly convey sewage from the campus according to established engineering standards and guidelines.
