2.0 Water Cycle Management

2.1      Background
The purpose of this section of the SWMP is to outline water saving measures that will be implemented in
the design and construction of the proposed development.


2.2      Wastewater Minimisation
To reduce the impact of water demand from the development and to minimise the loading on the existing
sewerage network, it is intended to reduce the wastewater leaving the site through the use of “at source”
measures. This will include:
         Water saving shower roses with a AAA rating or better
         Dual flush toilet cisterns that do not exceed 6 litres on full flush and 3 litres on half flush
         The use of 3 star (or higher) water efficient appliances


2.3      Stormwater Harvesting Tanks
In an effort to reduce the demand on town water supply and to assist with meeting water quality objectives
for this development, it is proposed to incorporate stormwater harvesting tanks on each lot within the
hydraulic design of the proposed development. A total volume of 55,000L is proposed, with a minimum of
50% of the roof area to be connected with first flush diversion capabilities as determined using MUSIC
modelling to achieve water quality objectives, refer section 3.0.
