DMA Design & Modelling of Urban Water Supply Distribution Network in India

Drinking water is an essential basic need for all lives. Most of the Urban utilities in India supplying water to communities, and charge for the water supply through metered consumption or flat rate basis based on the value of customer properties. However not all the water produced in water treatment plant reaching to consumers and generate revenue for water utilities. A substantial amount of water does not yield the revenue to the utilities which is called Non – Revenue Water (NRW). It is the difference between volume of water entered in to the supply system and volume of revenue generated. The water losses are mainly due to leakages and unauthorized consumptions1,2 . In order to understand the root cause and identify the major water loss prone area of the water supply scheme, the large water supply system will be divided in to small discrete areas, which is called DMA (District Metered Area). This chapter represents the approach of the DMA Design, which is the initial essential step for the formation of DMA along all the existing water supply schemes. This report has been prepared based on the on field experience in India3,4.
