Save water / Reduce your bills

Water efficiency advice

Whatever your business, small changes to how you use water in the workplace can make a big difference.

Here are some water saving tips for business customers.

Some tell-tale signs to help you spot leaks

  • Damp patches in or outside the property
  • Lush vegetation in dry periods may be indications of leaking pipes
  • Leaking overflow systems

Metered customers – diagnosing a leak

If your meter reading or bill is unusually high it may indicate you have a leak. You can use your meter to check if you have a leak on the pipework after the meter:

  • Turn off all taps
  • Find your water meter and take a reading (including the red digits)
  • Do not use any water for a length of time (e.g. overnight)
  • Read the meter again

If the second reading is higher than the first there may be a leak.

Many businesses now have smart technology that allows them to monitor and get data on water usage at regular intervals. This can help identify abnormal or unusual usage such as a leak. Regular monitoring means any such anomalies can be quickly investigated.

Employee awareness

Introduce water saving information, employee suggestions scheme or arrange a water efficiency session to increase awareness of the importance of using water wisely.

In the kitchen or canteen

  • Use a dishwasher instead of washing up plates and mugs separately – and make sure it is full before switching it on.
  • If washing by hand – fill a bowl of water rather than washing dishes under the tap let it run to waste down the plug.
  • A water cooler will give employees direct access to cold water rather than having to run a tap, alternatively keep jugs/refillable bottles of cold water in the fridge.

In the toilet or washroom

  •  Taps – A dripping tap can waste a lot of water. It’s often just a simple washer which is relatively inexpensive.
  • Urinal flushing – Uncontrolled urinals can waste hundreds of litres per hour. If you are replacing outdated equipment, using a control device can reduce water consumption by 70% by ensuring that flushing stops when the premises are not in use. Waterless urinals are also available.
  • Toilet flushing – Older toilets can use up to 13 litres per flush. If you have an older cistern, try a water saving device such as a “Hippo” or a “Save-a-Flush” bag. This will save between one litre and three litres per flush. You can also convert many syphons to dual flush.
  • Leaking toilets – Modern dual flush (button operated) toilets can leak due to sticky buttons or passing valves. This can waste over 250 litres an hour. Check all toilets for leaks – you can usually see a trickle of water running down the back of the pan.
  • Showers – Modern, efficient showerheads can help reduce water use by up to 50% and shower timers help remind people to take shorter showers.



  • Large quantities of water can be wasted on grounds maintenance particularly during the summer months.
  • Hosepipes and sprinklers – These can use 1000 litres per hour so keep landscape irrigation watering to a minimum. Grass is a great survivor and doesn’t need watering. Fitting a trigger nozzle to a hosepipe ensures water stops flowing as soon as it is released.
  • Water butts – Consider collecting rainwater in a tank or butt and using it for watering plants and shrubs. When landscaping try to select plants and shrubs that are tolerant of dry conditions.


  • Vehicle washing – try to reduce your vehicle washing activities. When washing vehicles or equipment consider recycling the water.
  • Window cleaning – Look for opportunities to reduce or prioritise window cleaning activities

Familiarise yourself with plumbing arrangements

  • Meters – Find and regularly read your meters and sub meters.
  • Watch out for leaks – Checking for leaks is something every customer should do regularly
