807 DMAs have been established and integrated in<br />
Netbase<br />
460 District Meter Points are logged and 91%<br />
provide good quality data<br />
<br />
374 Critical Monitoring Points have been set-up<br />
and 98% provide good quality data<br />

The Effect of Night-use on <strong>Operability</strong><br />
• The consumptions of very large users makes it<br />
difficult to estimate the night leakage and therefore<br />
affects <strong>Operability</strong><br />
• In Maynilad there are approximately 1400 large<br />
users<br />
• Currently the top 100 large users are continuously<br />
logged which helps with improving <strong>Operability</strong><br />
• Currently domestic and non-domestic night-use is<br />
being investigated so as to be estimated as part of<br />
the water balance, this will also improve<br />
<strong>Operability</strong><br />

Example - effect of Large Users on<br />
Night-use<br />
• A logged large user where the night use varies<br />
significantly<br />
10
Example - effect of Large Users on<br />
Night-use<br />
• A logged large user where the night use is almost<br />
zero because of an elevated tank and pump.<br />
