Dams, safety requirements and building consents

picture of damBuilding a dam

This page provides information to all those who own a dam or canal, or are planning to construct, modify or remove a dam, canal or a structure associated with a dam.

A dam's safety is dependent on its design, construction and how it's managed, operated and maintained so there are a number of requirements to take into account.

Note: The Government has decided that dam safety is better suited to being managed under the Resource Management Act (RMA) rather than the Building Act. As such, the Building (Dam Safety) Regulations 2008 have been revoked with effect from 30 June 2015.

Further information will be provided once this is known. In the meantime,  you may wish to vist the Department of Building and Housing's website(external link).

Dams register

Waikato Regional Council and other regional councils are required under the Building Act to maintain a register of dams for their respective regions.

The register enables councils to contact dam owners on matters of importance to them, such as new regulations and guidance material on dam safety.

If you own a dam, then you should check whether it should be on the register. Just contact us - there's no cost!
