Smooth Wall Water Tanks

3,500 - 30,000L

Smooth wall plastic water tanks are the most cost effective water tank available.

Important point to note, they cannot be buried and must be installed above ground. Water tanks typically rely on a hydraulic drainage system, and due to this the tank entry must be at least 500mm below your gutter height. Be sure to check the prospective tank location and the spouting height, as this may require you to change the tank you choose, or shift the location  of the water tanks. If the tanks needs to be partially buried to meet height constraints, or for visual purposes, check out the Promax Corrugated Tanks. Or alternately you may prefer a concrete water tank that can be fully buried.
