An Equivalent Tenement (ET) is a standard measure used to assess the impact of a particular development or land type on Council’s water and sewerage systems, relative to a standard residential property.
The purpose of this policy is to calculate water, bulk water and sewer developer contributions for any development which has an existing or proposed connection to Council's water and/or sewerage systems.

A standard residential property is considered to have an ET value of one, which equates to:
- one standard water developer servicing charge
- one bulk water developer servicing charge
- one sewerage service charge.
ET assessments for non-standard residential properties, commercial and industrial developments, however, are calculated by applying an ET factor in accordance with Section 5 of the ET Policy.
Water and Sewer developer contributions are applied under Section 64 of the Local Government Act 1993 which enables Council to levy developer charges for water supply and sewerage.
These charges are an upfront charge, levied to recover part of the infrastructure costs incurred by Council in servicing new developments, or additions/changes to existing developments.
Developer servicing charges provide:
- A source of funding for infrastructure required for new urban development or growth.
- Pricing signals regarding the actual cost of urban development.
A Development Servicing Plan (DSP) for both Water Supply and Sewerage needs to be prepared by any NSW Local Water Utilities (LWU) who propose to levy s64 charges for water supply and/or sewerage.
These DSP documents detail the calculation of developer charges and are required to be fair and transparent.
