Sewer system planning made simple – for small local authorities
Expanded Title:The aim of the project was to present a simplified approach to sewer system planning with accompanying tools that could be used directly as a low-technology (non-computer based) method for sewer system planning and to better understand the planning process. A key problem identified in small local authorities, during this research, was that staff at ground level responsible for service delivery was often limited in terms of basic knowledge regarding the sewer system, its operation and planning. The understanding of sewer planning as a simple tool was developed through a series of workshops, an extensive knowledge review and feedback from the reference group. The knowledge review covered sewer system planning, local practice, key issues pertaining to small local authorities, design philosophies, the dynamic planning process, sewer flow and flow components, as well as an extensive review of completed South African sewer system (master) plans. The knowledge review set the scene for development of low-technology tools that could aid staff in small local authorities while the workshops allowed for the tools to be developed and adjusted during the process. Three outputs were produced from the study: a) A technical report explaining the process of development of the tools and the key components which are important for sewer planning, b) A poster incorporating a simplified sewer planning process tool and sewer infrastructure estimates, and c) A low-technology toolkit comprising six loose standing booklets termed tools : The value of the simple tools presented here do not merely lie in their usefulness in sewer system planning, but rather in their value as training tools to gain understanding of the sewer system and its planning and to illustrate critical relationships between notable parameters typically used for sewer system planning. This should better prepare the staff at the local authorities to record and provide the desired information to consulting engineers who will ultimately compile a computer model which will be required during the master planning process.
