                  Rain Water Tanks
                  What you need to know before deciding on a tank
                  •   While Cardinia Shire Council has no official policy on rain water tanks, there
                      are issues regarding siting, building, planning and health requirements that
                      may be relevant in your case. This information sheet will address many of
                      these issues.

                  Important matters to be considered
                  •   Water is one of the most precious resources on earth yet it is the one resource
                      most often taken for granted.

                  •   According to Yarra Valley Water, the amount of water used by the average
                      Melbourne household each year is the equivalent of five average-size (52,000
                      litres) swimming pools.

                  •   Each year the average household uses nearly two swimming pools of water in
                      the garden alone!

                  •   Remember that correct mulching of your garden can save up to 70% of water

                  •   All plumbing work relating to rainwater tanks should be installed by a qualified
                      licensed plumber.

                  •   All rainwater tanks should be fitted with a child proof lockable tap and have
                      flywire covers on the leaf strainer and overflow that encloses the tank to make
                      them completely insect proof and maintenance free.

                  •   The rainwater tank should also be connected to the drainage system or to an
                      appropriate absorption line, so that overflow from the tank is disposed of in the
                      same way as normal roof runoff.

                  •   Ready access needs to be readily available between any rain water tanks and
                      the side or rear allotment boundary fence(s).

                  •   Rain water tanks and associated stand(s) should, for ease of access, be
                      located on a flat surface.

•   Rainwater tanks up to 3m in height are not to encroach into minimum side and
    rear setbacks (not street boundaries) more than 500mm.

•   A minimum setback of 2m is required from a street, other than the front street.

•   The combined height of the tank and stand is not to exceed 3m above ground
    level within 1m of a side or rear boundary. For tanks greater than 3m in height
    please contact Council’s Building Office on telephone (03) 5945 4392.

•   Health authorities advise that water contained in rainwater tanks should be
    maintained in accordance with the Department of Human Services publication
    titled “Your Private Drinking Water Supply.” The publication is available at
    Internet address
     Refer to additional information overleaf.

Is a Building Permit Required?
A building permit may be required where the cost of tank, stand and installation
exceeds $5,000; or the tank is physically restrained by connection to the building
for support (this does not include down pipe connection and the restraint of the
down pipe).

Are Planning Permits or Approvals Required?
There are no current planning restrictions related specifically to rain water tanks.
You should check your title, contract of sale, and Council’s Planning Department
on telephone (03) 5945 4224 for any restrictions that may be relevant. (eg. Lots
under 300m²) This is advisable in particular with regard to recent subdivided
estates where tanks are mandatory or recommended for ecological and
environmental reasons.

What about Building Over an Easement?
If a building permit is to be obtained, remember that building over an easement
requires the consent of the organisation having rights over the easement such as
South East Water, Yarra Valley Water, and/or Council.

•   It is advisable that an appropriate system be installed to exclude an initial
    quantity of rain water to catch and divert contaminates such as leaves,
    atmospheric pollution deposits, animal droppings, etc.

A brochure titled “Rainwater Tanks – A fresh approach to saving water” is
available from Yarra Valley Water for people who wish to install a water tank on
their property in an effort to help save water.
