Saving water

Saving water at work

On average, every worker uses 50 litres of water a day while at work. To help you save water in your workplace follow our handy tips

Employee awareness

Introduce water saving information, or arrange a water efficiency day, 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
  • run a bowl of water rather than let it run to waste down the plug
  • make sure appliances use low water or are ECO models
  • a water cooler will give employees direct access to cold water rather than having to run a tap

In the bathroom or toilet

Taps - a dripping tap can waste a lot of water. Change the washer immediately. Spray taps, push top taps or taps with infra-red controls can reduce consumption by up to half.

Urinal flushing - the automatic flushing of urinals can waste large quantities of water. Using a control device can reduce consumption by 70% by ensuring that flushing stops when the premises are not in use. If you are replacing outdated equipment, waterless urinals are now available.

Toilet flushing - low flush toilets use between four and six litres per flush. 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.

Showers - on average standard gravity fed showers use 30 litres per shower, while power showers use 60 litres. Aerating showerheads can help reduce water use by up to 50%.


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 grass watering to a minimum. 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 - when washing vehicles or equipment consider recycling water.

Familiarise yourself with plumbing arrangements

Stop taps - locate your inside and outside stop tap and ensure a number of people know where they are located. Check that you can turn them on and off.

Meters - find and regularly read your meters and submeters. Make someone responsible for reading meters either weekly or monthly. A marked increase in water usage may indicate a leak.

Protect against frost - make sure all hot and cold water pipes and tanks are insulated, especially in unheated areas of the premises. Insulating hot water pipes can also reduce fuel bills.

Watch out for leaks - checking for leaks is something every customer should do regularly.

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 toilets
  • leaking overflow systems

Metered customers

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:

  1. turn off all taps
  2. find your water meter and take a reading (including the red digits)
  3. do not use any water for a length of time (eg overnight or while you are out for the day).
  4. read the meter again

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