Frequently Asked Questions
Gold Coast Water is implementing a pressure and leakage management initiative
designed to reduce leaks, conserve water and ensure the security of uninterrupted
supply across the city.

Q1. What is pressure and leakage management?
Pressure and leakage management is a program of controlled reduction of water pressure and proactive leakage detection
and repairs to reduce water loss across the city. Water Pressure is reduced until an optimum range is achieved.

Q2. What is the optimum range?
The optimum range depends on the topography of the area, the length of the pipe transporting water from the nearest
reservoir, the height of the reservoir and the volume of water being drawn at any particular time. The aim of this project is to
find the optimum range for each supply area/zone, that produces the best service for customers, with the least amount of
interruptions due to main breaks.

Q3. How is the water pressure controlled?
Pressure is controlled using a modulating Pressure Reducing Valve (PRV). Use of the PRV provides adequate pressure
during peak periods of the day and subsequently reduced pressure during off-peak periods (especially at night time) in line
with customer demand. These PRVs have been installed within large pits concealed beneath the ground.

Q4. Why is Gold Coast Water introducing pressure and leakage management?
The outcome of this project will significantly increase the sustainability of our water supplies. A reduction in water pressure
minimises the amount of water lost due to leakages from pipe joints and fittings. It also reduces the amount of water
consumed across the city.

Q5. What is the progress of the program to date ?
The program has completed all infrastructure components, which includes 54 District-Metered Areas (DMA) installed across
the city. Currently 34 of the DMA are operational, with the remainder due to be commissioned during 2008.

Daily water savings are now 5.87 Million litres per day, this has been achieved by 34 pressure managed DMA that are
operational . This equates to 5% savings in Gold Coast Water’s daily water production. These savings are expected to
double when the all DMA are operational and project is completed.

Q6. What effect will pressure reduction have on my water supply?
The Program aims to reduce excessive pressure in the reticulation system. While some residents may notice a reduction in
pressure around the home, this should not affect day-to-day activities. Residents in trials at Burleigh Waters, Beenleigh,
Eagleby and Waterford reported little or no impact from the introduction of pressure control in their area.

Q7. What do I do if I don’t have enough pressure?
If you think that the pressure at your property is not sufficient, call Gold Coast Water’s Customer Contact Centre on 1300
366 692. GCW will arrange for the pressure to be tested to determine where the problem lies.

Q8. What if there is a problem?
If tests show a problem within Gold Coast Water’s network, staff will undertake measures to correct the problem. In some
cases, the problem may be on the customer side, in which case you will need to get a licensed plumber to investigate and
correct the problem. It may be as simple as removing a previously installed Pressure Reducing Valve (PRV), or may
require more extensive work to upgrade old service lines within your property.

Q9. How will this affect home dialysis patients?
The Pressure and Leakage Management Program should not affect home dialysis patients. However, all residents on the
Home Dialysis Register will be contacted individually to advise them of the project and answer any questions they may

Q10. How will the reduction in pressure affect my whitegoods?
Dishwashers, washing machines and other whitegoods should operate no differently with the change in pressure. In fact, it
is likely that there will be less wear and tear and less likelihood of hose breakages with reduced pressure.

Q11. How will reduced pressure affect fire fighting?
The changes will not affect fire-fighting capacity. Queensland Fire and Rescue has been consulted on all aspects of the
project including the proposed pressure changes for the city. Gold Coast Water is installing equipment with ‘smart
technology’ that can automatically increase pressure upon demand. The technology was put to the test in April 2005 when
a fire broke out in Eagleby, within one of the trial pressure management areas. Fire fighters had no problem accessing
water at sufficient pressure to fight the blaze.

Q12. My pressure is already too low?
If your pressure is already too low there may be other factors to consider. In many older areas of the city the internal pipe-
work becomes corroded resulting in a build up inside the pipe. This restricts the flow in the pipes and results in seemingly
low pressure. If this is the case you will need to engage a licensed plumber to investigate the best way for you to resolve
the problem.
