3Is your school water efficient? A water efficient primary school uses between 3-9 litres a student a dayA water efficient secondary school uses between 9-12 litres a student a day
4How much does water cost? water costs $2.01 a kilolitreSchools also pay for waste water.Sydney Water has info sheets on how to read water bills and undertake a water audit.Undetected leaks in schools canaccount for up to 70% of water use.
6Educating and managing for water efficiency School water management can beImproved by:Analysing water bills and determining school water efficiency eg via a water use calculator and DEC benchmarks.Conducting a water audit eg Sydney Water has a DVD on how to do it.Regular monitoring of the meter to check for leaks – templates are available through Asset Management/Curriculum websites and through Sydney WaterOther initiatives?Note: Stormwater can also be a sustainability issue in schools leading to direct impacts on local waterways. Stormwater can be managed and taught as an aspect of waste or water education by conducting a stormwater drain audit, spraying positive signs on drains, conducting litter surveys and educating students about where waste goes.
7School water saving actions Improve school water efficiency by:Reporting and fixing leaksUsing water from a tank to irrigate and flush toiletsMulching gardensMonitoring metersUsing a smart meter (eg Watersave)Putting water saving signs in toiletsUpgrading and modifying water appliances

10Energy costsElectricity is a major cost for schools, and like domestic electricity, costs are set to rise. Items like smartboards and the DEC laptop rollout are contributing to rising energy cost.For example, a connected classroom costs $800 per year to run and 24/7 and would emit 5,000 kgs of C02. The controls console would cost an additional $400 pa.
