Genetic algorithm based pressure management technique for leakage reduction in the water distribution system

Abstract

Leakages in water networks depends on its operating pressure. Hence by removing excess pressure from the water networks leakages can be reduced by an extent. A pressure management technique is presented in the research paper for leakage control as well as for removing pressure deficiency in East Zone WDS of Nagpur City, India as a case study. Depending upon the demand variation, variable speed pump is increase or decrease the water flow in WDS which can eliminate pressure deficiency and can reduce surplus pressure during higher and lower demand respectively. Pressure reducing value is utilized for further pressure reduction of remaining excess pressure for better leakage reduction. This paper is a case study which utilizes earlier proposed pressure management techniques of the author itself. The author has shown the utilization of earlier proposed algorithm for leakage reduction as well as removal of pressure deficiency in actual water distribution system as a case study. The algorithm leads to overall leakage reduction of 10.43% (30.94 l/s). Considering different load condition, daily water saving of 2.673 ML, which is good enough for the survival of a population of 17, 246 people more than the existing ones.
