Looks like there is a constant flow of water in the campus centre starting on Friday.
This problem has now persisted now for three weeks, apparently wasting about 0.2 M3 per half hour, 10 M3 per day, 3,650 M3 per year.
@DMU_Energy, any idea of the cost this represents? Any idea of the cause?

The initial problems have been caused by a faulty ball cock valve, this has now been replaced. However we have also had a leaky tap (now replaced) and a leaky loo (waiting for spare part). Really good that you have picked this up on SmartSpaces, shows has easy it makes identifying that there may be a problem.

Thanks for the update.
Looking on the web it seems a cubic meter of water costs about £3.50 - £5.00. Is this about right for DMU?
Assuming a conservative £3/m3 and a waste of 0.2 m3 per half hour this problem costs about £200 per week. Over four weeks (it's now been more than four weeks) that's around £800 in water charges. Left unresolved, this issue would cost more than £10,000 over a year.

The leak rate is about 0.3m3/hr, or about 5 litres a minute. That 's equivalent to a tap half open. DMU pay, in winter, about £1.50 per litre so that's nearly £4k per year. The loo has now been fixed . The baseload is still there ! This is when things get frustrating. There are no obvious leaks, no one's reporting anything, but somewhere 300 litres of water per hour is constantly running...I'll keep you informed.

£1.50 / m3 I think - £1.50 / litre would be more expensive than bottled water

Yes, sorry. Thank you for spotting.

Bottled water is often more than this actually. Especially in places where you have no alternative. It's an outrage. I am outraged by it. Outrageous it is. The very high price of bottled water in some places. Just think of the profit margins. Anyway, just thought I'd chip in.
By the way, you can edit posts if you wish to merge this erratum.

Problem solved. A leaky loo was to blame.
