Port Macquarie-Hastings Council
The Port Macquarie-Hastings Council area is located on the Mid North Coast of New South Wales, about 420 kilometres north of Sydney, and 510 kilometres south of Brisbane.
The Council’s vision is to provide a sustainable high quality of life for all. It has designed a programme to protect and enhance environmental values and provide for sustainable growth and development.
The Client’s Needs
Hastings Council wanted to ensure the reliable and safe supply of high quality drinking water to 4 communities: Wauchope, Comboyne, Long Flat and Telegraph Point, and build a water recycling plant at Port Macquarie. The council also wanted to meet revised water quality guidelines for safe drinking water.
The water supply for these communities is obtained directly from the local river systems and is then disinfected, prior to storage and distribution to consumers. Current deficiencies in water quality have been recognised by the Hastings Council, especially during periods of heavy rainfall which cause dirty water flows in the rivers which supply these local communities.
They conducted several investigations into water demands, water quality issues and water treatment options along with local residents, and decided to adopt Veolia Water Technologies.
Veolia Water Technologies Australia has been responsible for the design, supply, install, test and commissioning of 4 water filtration plants using membrane filtration at:
- Comboyne(680 m3/day)
- Long Flat (350 m3/day)
- Telegraph Point (1,300 m3/day)
- Wauchope(6,000m3/day, with the capacity to increase up to 18,000m3/day)
- Water reclamation plant at Port Macquarie (1,000 m3/day, with an extension capacity up to 2,000 m3/day)
All these water plants use advanced microfiltration technology. The Port Macquarie reclamation plant use Reverse Osmosis (RO) technology.
The fully automated treatment processes involve the limited addition of chemicals for simple coagulation and pH correction. The membrane filtration process is capable of removing most particles and organisms, down to 0.1μ, and will provide a very high standard of treated water supply.
All the water plants are designed to produce high quality drinking water (8,330 m3/day) and the backwash water is used for agricultural and playing fields irrigation (1 ML/day).
