CASE STUDY No 3
CITY OF TEA TREE GULLY
– IRRIGATION MANAGEMENT STRATEGIES
An Irrigation Management Strategy (IMS) was developed
by the City of Tea Tree Gully in 2003 when permanent
water conservation measures were introduced. The objective
of the IMS was to reduce water consumption by a
minimum of 20% while ensuring efficient irrigation
practices and ‘fit for purpose’ sport and recreational turf.
The results over the three year period from 2003 - 2006 have
seen a reduction of 31% or 290,000 kL per annum from
950,000 kL to 660,000 kL in overall water consumption
while maintaining the same area of irrigated turf to
satisfactory ‘fit for use’ standards. Further reductions were
achieved in the 2006/07 irrigation season as a result of level
3 water restrictions.
