Detect & repair leaks

Leaks waste water and cost your business money. They can also contribute to higher energy and discharge factor costs, as well as potential equipment or facility damage.

Check for leaks

It’s best to complete this test overnight, when most water using systems are turned off:

  1. In the evening, turn off any water using systems, such as irrigation. If you have processes that use water overnight make a note of these and their expected water use.
  2. Read your meter by recording the black (kilolitres) and red (litres) numbers from left to right.
  3. Read your meter again first thing in the morning.
  4. If the numbers have changed or you have unexplained water use (that is not the result of overnight water using processes), you may have a leak and further investigation may be needed.

Visible leaks

Look for:

  • Dripping taps
  • Sticking buttons on toilet cisterns
  • Check seals in urinals that no water is running
  • Wet areas when no water is being used in the vicinity, for example, pooling water on the ground

Hidden leaks

Look for:

  • Grounds that are much greener than surrounding areas
  • Areas of lawn that are very spongy
  • Wet areas in paving cracks don’t dry out
  • Pressure leaks – may be visible only when plant or equipment is operating

Maintenance

Your maintenance program should include regular checking of all water using devices, including:

  • Storage tanks
  • Irrigation systems
  • Wet areas (kitchens, amenities, laundries)
  • Devices that use a float valve to shut off water supply, such as evaporative air coolers, cooling towers, pool balance tanks and irrigation tanks.
