Faulty Meter

If it is suspected that a meter on any property is functioning inaccurately, MEWASS may compute the quantity of water supplied to the property during a specific period:

  • By having regard to the quantity of water delivered to the property in any previous or subsequent period or periods.
  • By having regard to the quantity of water delivered to any similar property during the period concerned.
  • In any other way that is prescribed
Customerís responsibility

Where a meter is not readily accessible we may ask you to make it reasonably accessible for reading and maintenance.

Readings by the customer

If MEWASS is unable to gain access to read the meter on a customerís property, the customer may be asked to read it and advise MEWASS. If the customer fails to provide a reading, MEWASS may estimate the amount of water used. The estimation will be calculated on the customerís water usage history at the property. Where your meter is not readily accessible we may ask you to make it accessible. However, we may still need to have access to the meter from time to time.
