Underground Concrete Water Tanks from Sydney Water Tanks

Concrete water tanks direct from the manufacturer - Sydney Water Tanks

Sydney Water Tanks is a leading manufacturer of underground rainwater tanks and proudly Australian-owned. The underground rainwater tanks that you buy from us are manufactured in our state of the art facilities in Sydney's South West.

Our tanks are individually wet cast from 40mpa steel fibre reinforced concrete, so there are no joints between the wall and floor. A watertight seal is ensured by one-pour casting and rigorous manufacturing processes that meet the requirements of AS1546.1. For extra strength, all inlets and outlets are cast in the tank, and the lid bonded and sealed in the factory.

Our rainwater tanks satisfy Basix requirements for houses, house renovations and swimming pools in New South Wales, and we provide you with a 30 year structural integrity guarantee for your peace of mind.
