High School Water Conservation Booklet Name: - Bundaberg ...

In a school environment, the following areas should be audited:• Urinals• Toilets (water closets)• Handbasins• Cleaning• External hose cocks• Sinks• Oval irrigation systems• Garden irrigation systems• Showers• Teaching areas• Swimming pool (if applicable)• Leakage (fixtures and underground pipes)• Miscellaneous areas including drinking fountains, canteen, staff rooms etc.The recommended strategies should consider any potentially adverse impact waterconservation could have on operations in these areas for example:-UrinalsGenerally there are four types of urinal systems currently operating within schools:1. Automatic (older style fill and flush)2. Manual pullchain3. Cisternmiser (these units rely on a drop in pressure within the water supply pipe-workin order to flush)4. Infra-red sensor urinals.Many urinals in schools are the automatic fill and flush types. They operate on acontinuous cycle where the urinal cistern slowly fills to a pre-set volume. Once the volumeis reached, the cistern flushes. After this, the cistern refills and the cycle repeats itself,24 hours a day, 7 days a week, 365 days a year. These urinals are inefficient and wastesignificant amounts of water.The main options available when considering retrofitting urinals to become more waterefficient are pullchain types, cisternmiser types, infra-red sensor types and waterlesstypes.ToiletsToilets usually consist of two sections, the cistern and the pan. Most pans are the samefundamental design. Cisterns, however, often vary in design. Although most moderncisterns are water efficient, many of the older style cisterns waste water, particularlycompared to current standards.Toilets will either have a single flush, using 12l per flush, or a dual flush with options of9/4.5l or 6/3l per flush.44
