Unmeasured water and sewerage charges

Unmeasured charges for water and sewerage consist of two elements:

  • a standing charge applied to all unmeasured properties; and
  • a variable charge, based on the property valuation. The property valuation is the Net Annual Valuation assigned to the premises by Land and Property Services. Click here to visit website
