Water tanks |
Water tanks are constructed from various materials such as plastic (polyethylene), fibreglass, concrete, steel and corrugated iron and come in a range of different styles and sizes. It is important to take note of the potential hazards relating to your water tank.
The Rainwater Tank Design Installation Handbook provides information on how all water tanks are designed, manufactured and whether or not they are safe to use. Australian Standard AS/NZ 4766:2006 Polyethylene Storage Tanks for Water Chemicals provides information specifically about poly tanks.
Before installing a water tank, check with your local council about any approvals you might need. There may be restrictions on the tank´s height or location, and you might need a plumber to install pumps or connections.
When choosing the right rainwater solution for your particular needs, think about:
- how you will use the water
- the type and size of tank you need
- the location of the tank on your property
- access to the site and site preparation
- whether water will be distributed by pump or gravity
- roof design, surface area and the number of tanks you need
- adding a first flush device to improve the quality of the water in your tank.
You can use rainwater to:
- water the garden
- top up the pool
- wash the car and for other general outdoor uses
- flush the toilet
- run the washing machine (cold water taps only)
- in rural areas where there is no main water supply you may use it for drinking water.
As part of the Water For The Future initiative the Commonwealth Government has a rebate which is available to consumers by submitting an application to the Department of Sustainability, Environment, Water, Population and Communities.
The National Rainwater and Greywater Initiative offers rebates for up to $500. Visit the National Rainwater and Greywater Initiative to learn more about available rebates, tank types and sizes, installation and costs.Rebate conditions require tanks to comply with recognised standards and be installed in a particular way.
When purchasing a Polyethylene or ´Poly´ water tank
- Check the tank has been independently certified to Australian Standards.
- Check where the water tank has been made - some imported water tanks are made from material that is not suitable for use, they may not have a warranty or include fittings that can not be replaced in Queensland.
- Make sure you are given written guidelines to help you maintain the base, fittings and installation of your water tank.
- Carefully read the warranty conditions and installation instructions, so that you know your rights and obligations, should you need to make a complaint.
- Buy quality products at reasonable prices, rather than focussing on long term warranties or unreasonably cheap deals.
- The industry body for poly tanks has a guide for buying and maintaining your poly tank.
Safety around your water tank
- If your water tank has a removable cover make sure it´s fitted with a locking device or the cover is secured with a screw or tek-screw.
- Never leave young children unattended around water.Young children can drown in water tanks.
- Never leave any containers of water unattended, including buckets with even small amounts of water. When you have finished using the container, always empty it immediately and store it away from young children.
- If you intend to use your water tank for drinking purposes, make absolutely sure it is safe to do so by adding a first flush device, using mesh over your gutters and adding a filter to your tap.
- Ensure any screens over entries to the tank stay in place to stop insects and mosquitos from entering.
- If your tank is damaged arrange for an inspection or repairs immediately. Large tanks full of water are subject to high pressure and can fail if damaged.
