When should I install a water tank?

2017-02-16 06:01

The best time to install a rainwater tank is when you don’t need it.

Fitting your water tank at the beginning of the wet season will ensure that you have as much water as possible to sustain you during the dry season.

How to maintain a water tank?

Keep the gutters free from debris with a range of devices or just by cleaning them out regularly. The water tank itself needs regular external inspections for leaks and an internal inspection for sludge every few years.

Plumbing and preparation

A plumber will be able to give you advice about water tanks, such as the cost, best location and size. It is important to ensure that your water tank’s overflow is securely connected to the stormwater system.


The ground where a water tank is going to be located needs to be levelled. Larger water tanks will also require either sand or concrete foundations. The tank manufacturer’s instructions will guide you.

Gutters and roofing

The guttering on your roof catches the water for your water tank and needs to be regularly cleared of any leaves or debris. Damaged guttering should also be repaired.

On some houses, the guttering may need to be adjusted to direct the water to the corner of your house where the water tank will be installed.

Lead-based paint and flashing or tar-based coatings found on some roofs affect water quality.

Make sure your roof material is non-toxic.

Be waterwise

use the water that falls on your roof and save water

(and money).
