Overview
Mullaly FRP tanks collect and hold stormwater below ground. The integral fibreglass rib design gives structural strength without a protective lining or coating, and the tank is rust and corrosion proof.
Each tank is designed to suit its site, and is manufactured in Australia at Tomago NSW and Kwinana Beach WA.
A large-capacity tank fits on one truck bed. The ribs also mean they are not limited by the water table, and no ongoing maintenance or inspections are required.
For retention and detention projects, see the stormwater retention tanks page on the Mullaly website.
