How To Install A Rain Water Tank
Setting up a drip-line irrigation system on a timer ensures the garden is watered efficiently. To save water as well, you can install a tank and harvest rainwater for garden use.
Slimline tanks range from 480-4000L, with a 2000L capacity storing enough water for the average backyard vegetable patch.
For basic watering needs, opt for a standard 2100L slimline tank that has a small pump attached to pressurise the system.
Position it on reinforced concrete and against a wall near a downpipe. For a tank this size, the slab must be at least 2400 x 900 x 75mm in size.
To secure the tank, mark the position of galvanised M8 Dynabolts in the slots in the moulded feet in the tank base. Move the tank aside to drill 8mm holes in the concrete to 60mm deep, then secure with the Dynabolts.
TIP A tank with a larger capacity can be plumbed for indoor use.
