Dwr Cymru Welsh Water

Water is becoming an increasingly expensive resource with mains, sewerage and trade effluent charges rising. However, introducing water minimisation measures is one of the easiest and most inexpensive ways to achieve cost savings.

Most companies and organisations know how much water they use, but may not always use this knowledge to help them reduce the amount of water consumed. Companies that adopt a systematic approach to water reduction typically achieve a 20 - 50% decrease in the amount of water they use. By using less water, companies save money on both water supply and wastewater disposal.

This simple guide is to help small businesses understand where they are using water and how they can practically reduce the amount of water being used or wasted. Regular surveys may also help to identify any hidden leakage problems which cost businesses large amounts of money every year.

Q. Do you know where all of your water meters are?

The billing meter is usually located in the footpath. Sub-meters may be installed on-site to gain a better understanding of where water is being used.

Q. Do you know what each water meter feeds?

It is important to understand how water is distributed and used around your site.

Q. Do you read your water meters regularly and record the meter readings?

Taking regular meter readings helps you to understand your water usage patterns.

Q. Do you read and reconcile any sub meter readings that are on site?

Reconciling the sub meter with the main meter readings will help to identify any potential leakage problems.

Q. Do you compare your meter readings to check for any abnormal consumption?

Regular meter readings can quickly show a rise in consumption that could indicate a leak.

Q. Do you investigate damp patches in the grounds of your site?

Investigating for underground leaks as early as possible is vital.

Q. Are your water bills checked before payment?

Check that the meter serial number and reading are correct.

Q. Are all your taps drip free?

Dripping taps waste large volumes of water and therefore money. Renew washers as soon as a dripping tap is reported.

Q. Have you considered fitting water saving taps?

Push taps with spray outlets can save over 50% of water used.

Q. Are any of your cisterns or tanks leaking or overflowing?

Defective ball valves waste large amounts of water and therefore money. Repair or renew as soon as a leaking overflow is reported.

Q. Do any of your urinals automatically flush when no-one is on the premises?

Make sure that no water is being used unnecessarily when no-one is on site.

Q. Have you considered fitting water saving controls to urinals?

You can make major cost savings by installing water saving devices such as urinal controls in wash rooms.

Q. Are plugs fitted in water basins?

 Captive plugs encourage staff to wash hands from the basin rather than under a running tap.

Q. Are your pipes and tanks adequately protected from frost damage?

Ensure you are prepared for any cold spells by insulating tanks, cisterns and external pipework. Not only is a burst pipe very inconvenient it can also cost your business a considerable amount of money in wasted water.

Q. Is your water pressure set at the minimum level for your needs?

If your water pressure is over 5 bar it is worth fitting a pressure regulating valve. This will reduce the volume of water you use as well as protecting your water fittings from bursts and leaks.

Q. Do you lose water and energy through unnecessarily long pipe runs?

Long pipe runs allow heated water to cool which is then run to waste by users. Improved plumbing and water heating design can save water and heating costs.

Q. Are landscaped areas kind to the environment?

Collecting and using rainfall to water plant will save water and money. Use mulch and chippings to prevent evaporation and weed growth.
