Water Management Plan

An integrated Water Management Plan considers the collection, use and treatment of all water within the site, including stormwater management and firefighting and incorporates all these aspects within the design and efficient functioning of the total project.

The key components to integrated water management are: conservation, recycle and reuse. Using an integrated approach to the planning, design, implementation and operation will result in beneficial outcomes in both the economic and environmental aspects of a development. Potential water management initiatives considered appropriate for implementation include:

  1. Demand Management
  • Community awareness and education
  • Xeriscape (dry) and Water Wise gardens
  • System pressure control
  • Water saving devices, including water efficient toilet systems
  • Appropriate pricing structure
  • Irrigation management
  • Water audits and leakage control
  1. Supply Substitution
  • Dual reticulation
  • Rainwater tanks
  • Sewer mining
  • Stormwater harvesting
  • Aquifer storage and recovery
  • Open storage
  1. Water Sensitive Urban Design
  • Stormwater Quality Improvement Devices
  • No net increase in peak discharge; and
  • Stormwater harvesting.

The general supply and usage options involved in the balanced management of water is summarised as follows;

Water and Waste Water Management Plan

The main principle behind water management is to look at the predevelopment regime when rainfall and nature had a direct connection.

The water from the primary sources is now collected, used, treated and returned to the environment. The amount returned should reflect the original supply to keep nature in balance.

The connection between the water supply, use and waste water is shown in the diagram on page 56 which also shows the connection between recyclable and composting waste and water.

Water is essential to life and is connected to all other life forms as well as humans. We have a right to clean water. It is given freely and nature provides all our needs but with our present explosion of population we need to protect and value our water supply to stop pollution and waste.

Our planet is 90% water but only 3% of this comes as potable and renewable rain. The balance between nature, biodiversity and rainfall must be understood and maintained to ensure a sustainable supply.

The master plan incorporates a collection, treatment and reuse system by regenerating and using the natural environment within the site. Reed beds and aeration rock flow paths purify the stormwater which is then pumped back into the greywater recycling system by solar powered pumps to be used for all purposes except personal washing and drinking.

These ponds also create a pleasant natural environment for passive recreation and enjoyment as well as providing important habitat for wildlife which will increase because we have given them a home.

The connection and balance of nature is always so simple.
