Water Saving Toilet Cistern Converters Case Study
Many older style toilet cisterns flush away up to 12 Litres of water each time the button is pressed. Dual flush toilets have largely superseded single flush models in the Australian market and it's not uncommon for these to use only 4.5/3 litres per flush, down from 12/6 litres only a few years ago.
Achieving significant step change in efficiency often requires complete replacement of each toilet suite, costing up to $1,500 per unit. Across a 25 storey office tower this could represent a cost of almost $200,000. As water is a relatively cheap resource, these projects offer very poor returns on investment and cannot be justified solely on water conservation grounds. In most cases, toilets don't get replaced until such stage as a refurbishment is planned, typically in line with leasing cycles which can be up to 15 years.
In NSW, Victoria and Queensland during the period we trialled a device called the Water Saving Toilet Cistern Converter. This simple device lets the user control the toilet flush. The longer the button is held, the longer the flush. Water flow stops when the user takes their finger off the button. Following this test, approximately 90 toilets across our portfolio were fitted with these cistern converters, significantly reducing toilet water consumption of older toilets while waiting for the lease cycle to justify their replacement. This is a relatively simple and cost-effective way of becoming 'faster, lighter and enduring'.
