Business Customers Water Efficiency How to Read Your Water Meter

Most commercial and industrial properties have a metered water supply. The water meter is usually located by the boundary of the property, often near a road. If the site has more than one incoming water mains, each supply should be fitted with a meter. As a minimum, your mains supply meter(s) will allow you to monitor water consumption of the site on a routine basis (daily, weekly or monthly).

Metered companies are responsible for the water use recorded on their meter - including wastage and leaks. The diagram below shows a typical water meter. The white digits in the ‘blue box’ display cubic metres (m3) and those digits shown in red display 1/10th (100 litres) and 1/100th (10 litres) of a cubic metre.
