Potential Customer FAQs

Q1. Does WBW provide a constant supply of water all year round?
Yes, the WBW pipeline provides water all year round.

Q2. How easy is it to transfer from using groundwater to WBW water?
A. WBW can match the flow produced by your bore pump or mains outlet so it can be as easy as re-organising your plumbing. However, you need to make your own assessment of what is required and possibly consult an irrigation specialist.

Q3. How does the price of using WBW water compare to using other sources of water for irrigation?
A. WBW’s compares very favourably with the cost of other water sources.

Q4. Is it easy to use?
Yes, the WBW system is very easy to use and the system displays your flow rate and usage at your outlet

Q5. Do I need a pump and power?
WBW water is supplied at a pressure that will suit most on-farm drip irrigation systems, so generally you will not need to re-pump the water.

Q6. Can I choose where my outlet will be?
No, the location of the outlet on your property is at the discretion of WBW, but you will be notified prior to installation.

Q7. Can I blend the water with other water?
Yes, but the interface must be designed carefully with an approved backflow prevention device. Any cross connections must also be approved by WBW. Cross connections with mains water must be registered with SA Water.

Q8. Will I need a filter?
Yes, we recommend having a filter and it will be your responsibility to filter the water to a standard appropriate for your on-farm drip irrigation system. Most existing users have the same filters used for other water supplies eg. automatic screen, disk filters or sand filters, but adequate on-farm filtration is very important. WBW does filter the water prior to delivery… so don't be surprised if filters go for long periods without requiring a flush.

Q9. What do I do with backflush water?
The backflush water must be disposed of properly – you can either recycle backflush water or use it to irrigate windbreaks etc

Q10. How many megalitres (ML) of water will I need?
That is a decision you need to make. Consult your records and ask your advisors about recommended precipitation per year in your location. WBW measures your water usage on an annual basis from 1st July to 30th June. You will also need to take into account the flow rate that you require because each megalitre purchased has an associated flow rate attached. Please ask us if you require more information.

Q11. If flow rate is associated with the megalitres that I purchase, what should I take into account when purchasing megalitres?
For each megalitre purchased you will be allowed to draw .476 kilolitres (kL) per hour. For example, purchasing 50 ML will allow you to draw 23.8kL per hour. So you will need to determine the flow rate and the volume per annum that you require. There are two parameters that will determine the flow rate required. The first parameter is the volume or precipitation of water that you want to be able to apply over a given period eg. 10 litres per vine per day or 24mm per week. The second parameter is the flow required to suit your irrigation “stations” or “shifts”. This will depend on how many drippers you need to operate at one time and the flow rate of those drippers. Please ask us if you require more information.

Q12. Can I use the water 24 hours per day?
No, you can use the water 18 hours in any 24 hour period, which means you could irrigate for 36 hours straight over a two day period.

Q13. How does WBW control my water flow rate?
We don’t control it, you do. You do this by controlling how many drippers you turn on together or by installing a flow control device. WBW monitors your outlet to make sure that all users are doing the right thing and not exceeding their flow rate or daily usage hours.

Q14. How do I know what costs are involved in connecting to and using WBW water?
A draft Water Supply Agreement would be provided to you by WBW which clearly sets out the pricing mechanisms.

Q15. How does the salinity of WBW water compare to other irrigation water options?
The salinity of WBW water compares favourably with the average salinity of groundwater in the region.

Q16. Does reclaimed water affect the wine being produced from the irrigated grapes?
No. WBW has been distributing reclaimed water to grapegrowers in the Southern Vales region since 1999. Several technical studies have proven that the use of recycled water has no discernable affect on wine produced from these vineyards. Vine roots extract pure water from recycled water.

Q17. How safe is reclaimed water for irrigation?
Reclaimed water is completely safe for drip irrigation so long as the safety guidelines provided to you by WBW are followed.

Q18. What approvals do I need from government authorities to use this water?
Most approvals are the same irrespective of whether groundwater or reclaimed water is used. WBW obtains approval from the Environment Protection Authority (EPA) and the Department of Health (DEH) through an Irrigation Management Plan.

Q19. Does the WBW reclaimed water smell?

Q20. How long has the scheme been operating and how successful is it?
The WBW scheme has been operating since 1999. A group of primary producers in the Southern Vales region collaborated to build the pipeline and now there are more than 140 users of the WBW system. It is reliably providing water to irrigate more than 4,000 acres of prime land for grapegrowing and other fruits e.g. olives.

Q21. Does the WBW system suffer from much downtime?
No, the system has proved to be extremely reliable. Regular pre-emptive maintenance on plant and equipment is carried out every year.
