Are there any other examples of where a golf course or playing field has used recycled wastewater?
Recycled water has been used for the irrigation of many other golf courses and playing fields. Case studies are available at www.veoliawaterst.com and www.sydneywater.com.au.
Are there water restrictions with recycled water usage?
The water management system has been designed with sufficient capacity to ensure there will be adequate water for use within the community. Emergency capacity has been considered and built into the recycled water plant, however water restrictions on garden use may apply in times of severe drought. During these periods you may experience either reduced flow or reduced pressure at which time, residential irrigation systems should be turned off.
Can I choose not to connect to the new system?
No. As Sydney Water is unable to provide sewer services to the community at this point in time, a private Recycled Water Treatment Plant has been constructed to service the community’s needs. This requirement was included within your Contract of Sale at the time of purchasing your land, outlined within the Community Management Statement, Section 19 Services.
Do I still need to setup an account with Sydney Water?
Yes, each home is connected to the Sydney Water network for potable water and therefore each owner will need to set up an account with the Sydney Water.
How does the recycled water reach my home?
Recycled water is supplied to your home in a purple (lilac) coloured pipe network which is separate from the drinking water supply network. Recycled water is measured using a separate purple coloured meter and connections are coloured purple. All recycled water connections and fittings are designed not to be compatible with potable water fittings as they have opposite handed threads, that is, a potable water fitting cannot be screwed onto a recycled water tap or fitting. The drinking water meter is usually green, which is designed to prevent confusion and will be read and billed separately by Sydney Water.
How is the recycled water treated and made safe for its intended users?
The current Recycled Water Treatment Plant process involves a 4-barrier treatment to remove viruses, bacteria and protozoa including a Biological treatment process, membrane filtration, followed by Ultraviolet and finally chlorine disinfection to meet golf course irrigation recycled water guidelines and the Australian Guidelines for Recycled Water distribution via the lilac network.
How much recycled water will be produced?
The Recycled Water Treatment Plant has commenced production at a rate of 400,000 litres a day of treated water (approximately 146 megalitres a year), the equivalent of 60 Olympic swimming pools. With the community growing over the next decade, the plant will progressively be upgraded to produce 1,200,000 litres a day (approximately 440 megalitres a year), the equivalent of 175 Olympic swimming pools of recycled water in stages over the next years.
How will I be billed for this service?
Customers will receive a bill for their wastewater services and recycled water usage on a quarterly basis.
If I own a swimming pool, are there any special precautions I need to take?
Yes, because the Recycled Water Treatment Plant can be upset if suddenly presented with large surges of chlorinated or salt water an underground water storage tank must be placed to capture pool overflow.
What can’t I use recycled water for?
Recycled water cannot be used for drinking, cooking, personal washing and bathing, indoor house cleaning, filling of swimming pools, recreation activities, evaporative coolers, washing pets and animal drinking water. Although the recycled water is treated to a very high quality and standard, it is not approved for being used as drinking water and therefore, in the event that you consume recycled water, it is recommended that you seek medical attention immediately, as a precautionary measure.
What controls are put into place to make sure recycled water is safe for use?
The unique plant design was made in line with Australian Guidelines for Water Recycling (AGWR1). The plant is being operated Monday to Friday and monitored online 24/7 to ensure safe treatment. Additionally, weekly checks of treated water quality, in accordance with WICA and IPART licence requirements, is being performed by an independent third party NATA accredited laboratory to verify the water quality.
What if I want to only connect to sewer and not recycled water?
The Recycled water and wastewater services are inter-reliant and as such, connection to both the wastewater and recycled water systems is necessary.
What is recycled water?
Recycled water is the water produced from the treatment of the wastewater collected from the residential homes, retail, school and future commercial buildings resulting in a high quality treated product (effluent), which is then suitable for irrigation of the golf course, gardens and toilet flushing.
What is the Recycled Water Treatment Plant (RWTP)?
The Recycled Water Treatment Plant treats the domestic wastewater from homes and other retail and commercial properties to a high quality in order to be reused for non potable uses, including golf course irrigation, garden irrigation and toilet flushing. The recycled water is not suitable for drinking purposes.
What is wastewater?
Wastewater is water that is collected from the residential houses, retail, school and future commercial buildings including sewerage waste, household greywater, and pool water run-off.
What is WICA?

Private companies require a NSW WICA (Water Industry Competition Act 2006) licence to construct, operate and/or maintain water industry infrastructure.

These activities are regulated by the Independent Pricing & Regulatory Tribunal of NSW (IPART) and the Energy & Water Ombudsman NSW (EWON).

Veolia Water Solutions & Technologies was recently granted a Network Operator’s Licence and a Retail Supplier’s Licence, allowing the company to operate and maintain the $7.2 million Wilton Recycled Water Scheme.

A separate reticulation system (pipe network) is being built to supply the recycled water to the golf course, public spaces, retail customers and households.

Where can I obtain more information on the Recycled Water Scheme?
Customers are advised to read their Customer Contract and full Terms and Conditions. Further information can be found at: www.myrecycledwater.com.au www.bingaragorgeonline.com.au Within your Contract of Sale
Which substances should NOT be put down the sink, toilet or drain?
Under NO circumstances should any form of Wipe, (“flushable” or otherwise) be introduced into the sewer system.!!!!
The pumps in the sewer system choke on these wipes as they do not disintegrate as toilet paper does and clog the pumps.

Fat, oil and grease, such as meat fats including lard, butter, margarine and cooking oil and shortening, food scraps, baking goods, sauces, dairy products, phosphates, ammonia, bleach, coffee grinds, egg shells, produce stickers, medications, corrosive substances that are either acidic or caustic, flammable or explosive substances, solvents, paints, turpentine, nail polish, polish remover, motor oil, transmission fluids, anti-freeze or other toxic chemicals, condoms, rags, flushable cat litter, paper towels, feminine hygiene products and general garbage.

VWS currently holds a network operator’s licence to operate the plant and network. We also hold the retail licence for the Bingara development, for the supply of sewerage services and recycled water for the development. Under VWS’s licence Lend Lease manage all of the resident retail functions..
Why was there a need to build a private Recycled Water Treatment Plant?
As this development is located outside of the normal wastewater network serviced by Sydney Water, it was necessary to construct a privately owned and operated treatment plant to service the community’s needs. It was also a requirement under the State Deed Approval for Bingara Gore to provide for sewerage services as the development is located outside of the normal wastewater network serviced by Sydney Water. To be able to deliver this service, it was necessary to construct a privately owned and operated treatment plant to service the community’s needs that is regulated under the WICA act. The type of plant chosen was based on constructing a very efficient, environmentally positive treatment plant where the treated effluent could be re-used back to the community for irrigation and toilet flushing, reducing the demand for potable water.
