A dam is defined as anything in which by means of an excavation, a bank, a barrier, or other works water is collected, stored or concentrated. Dams can be privately owned by an individual or business, or by a Government agency. They can be used to store water for drinking, industry or farming, to protect property from flooding, or for recreation.
Dams are regulated by the Water Act 1989. Under the Act, dam owners and managers are legally responsible for dam safety and accountable for the damage their dams may cause.
Dams and the planning system
Dams should be considered in planning permit applications for new development and planning scheme amendments Planning Practice Note 46 - Strategic Assessment Guidelines.
The Planning Policy Framework Clause 14.01-1S Protection of agricultural land requires planning to consider compatibility between the proposed or likely development and the existing use of the surrounding land.
Refer to Guidance for setback distances near dams (Department of Environment, Energy and Climate Action webpage) which provides guidance for setbacks from dams and property boundaries, and proposed development.
The setbacks are intended to provide access to the dam:
- in the event of a safety incident or emergency
- for ongoing maintenance and safety management
- to allow space to implement dam safety upgrade works.
A planning permit isn't required for a dam under Clause 62.02-1 Buildings and works not requiring a permit, if a licence is required to construct the dam or to take and use water from the dam under the Water Act.
