Analysis of catchment G in Oakey's sewer network

Abstract

Oakey is a small town located 25km west of Toowoomba and has a population of approximately 4000 people. Current and future development of urban areas in Oakey is leading to a greater strain on the current sewer network. A large amount of the network was installed in the mid sixties. Council is looking at ways of managing the current network to satisfy future demand requirements. This text aims to model a catchment in the town’s sewer network and provide recommendations on current and future work requirements. Modelling and analysing the chosen catchment has shown that even though on paper sections of the network are not ideal, the current flows in the area analysed, are well below the design capacity, hence the network functions with minimal problems. The main area of interest in this catchment was the limit storage capacity of the pump station. Future upgrades to the chosen catchment will include the possible construction of a new pump station. This document gives recommendations on this.
