Water Tank Installation Guidelines & Tips

Water tank installation guidelines for polyethylene or plastic water tanks may vary slightly between different manufacturers and should be checked. The article below is a fairly generic guideline on installing poly rainwater tanks for domestic use.

Site Preparation

There are several factors that will determine the most appropriate location of your rain water tank. First walk around your house and note the locations of your downpipes. The closer the water tank is to a downpipe, the simpler your install will be.

Once you have selected an appropriate site, you can begin to prepare this site for the water tank.

1. Check the relevant regulations relating to rainwater tank installation with your local council.
2. Your rainwater tank should be handled with care. When moving into position, avoid rough and sharp surfaces.
3. The site must be a solid, level and compacted base that extends beyond the diameter of the tank that will not be eroded by wind or rain. Suitable bases include brick, concrete, gravel or solid dolomite surface between 300mm and 400mm in depth.
4. Water tank stands can be used but must be designed by a qualified consulting engineer.

Tank Plumbing

Please ensure your water tank is installed by a qualified plumber in accordance with your local council regulations.

Gutters and Roofing

The guttering on your roof is a key component in your rain harvesting system and will need to be cleared of any leaves or debris. Damaged guttering should be repaired.

Test to see if your guttering directs water to the corner of your house where the water tank  or water tanks will be installed. If water is not directed towards the corner of your house then it should be adjusted to maximise your rainwater harvesting capacity.
