The opening ceremony of the Sydney 2000 Olympic Games was a window for the rest
of the World to look inside the real Australia. And amongst everything that makes Australia the country it is, we
proudly displayed to the world hundreds of galvanised iron rainwater tanks. Given the vital role these tanks have
played over the years in Australia, it was quite appropriate to celebrate them in such an important way.
rainwater tanks have been an integral part of the Australian landscape. Yet, for the latter half of the last century, large
cities such as Sydney turned their back on this national icon in favour of centralised water supply systems. The
current drought in Australia has however once again emphasised the importance of rainwater tanks for Sydneysiders.
And throughout the metropolis the rainwater tank is staging a comeback.
Kogarah Municipal Council became
the first local government authority in Sydney to promote the use of rainwater tanks in all the schools within the
council area. To facilitate this, Council in partnership with the Sydney Water Corporation has funded the installation
of rainwater tanks in all the schools. The project also involved the University of Technology Sydney, which assisted
with sophisticated yield and demand modelling to determine the right storage volumes needed for each of the school.
A continuous simulation model was used to determine the appropriate tank volumes, based on factors including
water usage patterns and available roof surface areas for harvesting.
Installation of rainwater tanks in Kogarah
schools, is likely to result in saving thousands of litres of drinking water per annum, as drinking water is now being
substituted with rainwater for irrigating gardens and/or for toilet flushing. In addition to the installation of rainwater
tanks, a complementary water education program was also developed and implemented as part of the project.
Education program involved training students to carry out water audits of the school complex, tank decorating
initiatives as well as the development of a Water Conservation Action Plan for the school. Involvement in the
educational program provided students with applied knowledge and understanding of water conservation, which is
central to sustainable decision-making in their life. This paper provides an insight into Rainwater Tanks for Schools
Project, highlighting the important educational role the project has played in increasing the awareness of Kogarah’s
children with respect to water conservation.
