BWSSB Water Data

[Rahul Saxena]

BWSSB claims to supply 900 million liters of water per day. Does anyone have pointers to data on where all this water goes? There is some info (below) that talks of 400 MLD being "lost" to various causes, but nothing I could find on the 500 MLD that is supposedly "supplied" ... to whom, for what?

Ref http://www.deccanherald.com/content/168655/half-cauvery-water-supplied-city.html, please help in the interpretation:

	Est/Low	Est/High	Est/Low	Est/High
Total water supplied			900 MLD	900 MLD
Accounted For			500	500
Not Accounted For (breakup below)			400	400
unaccounted for water (UFW)	35%	35%	140	140
non-revenue water (NRW) to unauthorised connections	10%	10%	40	40
old water meters (under-report consumption?)	5%	5%	20	20
public taps	12%	15%	48	60
unauthorised connections (double-counting NRW?)	8%	10%	32	40
leakage at ground level reservoirs (GLRs)	3%	5%	12	20
leakage at networks	12%	15%	48	60
leakage in household connections	10%	15%	40	60
BWSSB offices in the City and water tankers	3%	3%	12	12
	98%	113%	392 MLD	452 MLD
