Saving water a drop at a time

The third flag that schools in the Green School programme can earn is for water conservation.

Scoil Cholmcille estimates that changes to its plumbing have helped to save more than 4,000 litres every day it opens, or enough water to fill four Olympic swimming pools a year.

They installed push taps that limit the amount of water used, and the large urinals that flush automatically only activate a fraction of the times they used to, as well as being switched off at evenings, weekends, and during holidays.
