What can I build?

A water tank can be constructed out of steel, fiberglass, stone, concrete or plastic. The location of a water tank should be in the rear yard of a property and not be visible from the primary or secondary streets.

The base of the water tank is to be located directly on the ground or supported by a manufacturer designed tank stand not exceeding 300mm in height.

Do I need a building permit?

The Building Regulations 2012 states that a Building Permit is required prior to the construction, erection, assembly or placement of a water tank more than 5000 litres in capacity.

For smaller water tanks less than 5000 litres and not higher than the height of a boundary fence i.e. 1800mm, a Building Permit is not required.

How long does it take to get a building permit for a water tank?

The Building Act 2011 sets time frames in which the City has to assess and determine an application for a Building Permit. The applicable timeframe depends on whether the building application is Uncertified or Certified.

It is important that you are aware of allowed time frames prior to lodging your application and that your application documentation is complete.

Should further information be required by the City in order to assess the building application, the applicant may be given up to 21 calendar days in which to provide the outstanding information. If the information is not received within the 21 days, the application may be refused unless a mutual consent has been granted for a further 21 days.

Uncertified Building Applications (BA2)

An Uncertified Building Application can be submitted for Class 10 structures such as a water tank.

The City has up to 25 business days from the date of lodgment to assess the application and issue a Building Permit. The required Certificate of Design Compliance will be issued by the City as part of the application process.

Certified Building Applications (BA1)

A Certified Building Application can be submitted for all Class of structures.

Prior to lodging a Certified Building Application to the City, a private Building Surveying Practitioner would need to be engaged to issue a Certificate of Design Compliance.

The City has up to 10 business days from the date of lodgment to assess the application and issue a Building Permit.

How long until my permit expires?

A Building Permit is generally valid for two years from the date on which it was granted.

If more time is required to complete the building works, you can apply for an extension of time of up to a further six months by making a formal application and paying the prescribed fee.

What happens when I have completed my building works?

The nominated builder on the Building Permit must submit a Notice of Completion BA7 form to the City within seven days of completing the prescribed building works.
