For most household customers, all water supplied is of drinking water quality, this is called ‘potable water’. Water that is not drinking water quality is called ‘non-potable water’. Some water companies supply non-potable water to industrial customers as well as potable water.
Non-potable water is usually charged for in the same way as potable water but generally the volumetric charge for non-potable water is lower because it does not include the cost of treating the water to drinking water standard.
For more information about non-potable water, contact your water company.
