This Bar Chart shows an eight day view of water consumption, again Monday to Monday in 30
minute periods. Water can be clearly seen to be used 24 hours a day and over the weekends,
when the building is closed. No water should be used during early morning or at night on
weekdays and no water at all should be used over the weekend. This graph showed the site had
a major water leak, even though no pools of water could be found. The leak was into a drain
which was not visible to staff. On a number of occasions we have effected savings of around
80% on water used, although meter readings failed to highlight any problem.
