Optimal Design of Water Transmission Networks

The primary objectives of the National Water Policy of India 2002 are to improve the performance and cost effectiveness of programmes in the field of drinking water supply and to ensure the availability of an adequate quantity of drinking water of acceptable quality on a long term basis. This is possible only by providing low cost but practical and effective solutions to identified problems, associated with the supply of drinking water, through the application of available scientific and technological inputs. For effective and economical management of water supply systems, the National Water Policy identified thrust areas which need intensifying research efforts. These areas include economical designs for water resource projects, better water management practices, and improvements in operational technology. This paper reviews the methods for analysis and design of multi reservoir multi junction water transmission networks which are important components of every water supply system. Recent improvements in design methods which incorporate cost aspects are also discussed in paper.
