The average school uses 10
cubic metres (10,000 litres or 10 tonnes) of water per day and
dirties the same amount. Each pupil uses around 35 litres per day.
Apart from drips, taps can be a source of water loss - or saving -
in a number of other ways:
Self-closing taps (press taps)
Taps left running can waste enormous amounts of water.
There are various types of self-closing, press operation taps that
cut the supply shortly after use. They can waste water if they jam
in the on position and so need to be inspected and maintained
regularly.
Spray taps
Taps with spray heads can reduce water consumption by up to 50 per
cent, but, as with push taps, need regular maintenance to ensure
that the head does not become blocked with soap, grease or lime
scale.
Toilets - urinals
Most urinals are flushed by an automatic system that controls the
flow of water at a minimum set rate per hour when in use. This rate
will depend on the number of urinals and the volume of the cistern.
Do your urinals flush when there's nobody there?
Contact your local water boards
Their address is in the phone book. Ask them who are the biggest
water users in your area - and why. Ask the users if they have ways
of cutting down on their water use. Ask to see the washrooms at the
biggest local business. Tell them they could save water - and money
- with push taps and more modern urinals!
Global Action Plan sets challenges including reducing water use by
10 per cent and helping to reduce pollution in the UK.
