ASSESSMENT OF NON-REVENUE WATER (NRW) IN MYSORE CITY - A MEANS TO ACCOMPLISH 24X7 WATER SUPPLY

摘要

Non-Revenue water (NRW) is the difference between System Input Volume (SIV) and billed authorized consumption. This paper is focussed on calculating NRW in the District Metered Areas (DMAs) of Mysore city to which River Kabini is the source of water supply. Kabiniriver supplies water to 17 DMAs, regions of Dattagalli, MUD A Layout and Bank Colony in Mysore. Water balance for this distribution network is established based on the collected data and field surveys carried out. Results show that 28.13% of the SIV is accounted for NRW of which nearly 7% is from physical losses.
