Study on distribution blocking system in a northern city of China by using a hydraulic model

摘要

WNW7.0, software for water distribution analysis and design, is used to establish the hydraulic model of water distribution system in a northern city of China, and to analysis the changes of pressure and water quality in the water distribution system after applying single DBS and double DBS. The results showed that the pressure ranges in the distribution system trended to be more equal and water quality had been improved greatly using the developed DBS method.
