  • Volumetric charge (kL)
  • Biochemical Oxygen Demand (BOD)

New Customer Contribution Framework
New Customer Contributions (NCCs) are an upfront payment levied by us when a customer builds, develops or extends a property or business where connections to our water and/or sewerage systems are required to be installed or altered.

NCC rates are updated on July 1 each year can be found in our Tariff Schedule, linked above.

Existing serviced properties are generally deemed to have already contributed NCC charges for one Residential Equivalent Tenement (RET), unless specific information on that property indicates otherwise. Refunds are not payable by us where a development reduces the RET on a property.

In instances where standard NCC charges do not apply, the charge will be negotiated. These Non Standard NCCs will be applied in accordance with our Negotiating Framework.
