Sydney Water Tanks Product Range

At Sydney Water Tanks we have a range of products to suit the individual needs of our customers. Born from the experience and expertise of The Martins Group and our BioSeptic product, Sydney Water Tanks has quickly become a leading provider of premium underground rainwater tanks that have set new benchmarks in the industry.

Water tanks

Our rainwater tanks are designed to be installed underground, so they are out of sight and out of mind. We offer a range of rainwater tanks, ranging from 3800 litres – 11500 litres.

All rainwater tanks from Sydney Water Tanks are built from long-lasting, extra strong steel fibre reinforced concrete. With a 30 year structural guarantee, a Underdeck water tank from Sydney Water Tanks efficiently provides a quality supply of rainwater to your toilets and outdoor taps.

Rain Switch

Rain Switch, a feature of a Sydney Water Tank, controls the water supply from the rainwater and town water system in your home.

The intelligent Rain Switch automatically detects when tank levels become low and changes supply to town water. As soon as the tank refills to a useable level, the Rain Switch changes supply back to tank water without any manual input.

Onsite Detention Tanks

Sydney Water Tanks’ onsite detention tanks and detention control pits are designed on an individual basis to ensure that your stormwater management needs are met.

Pits and Grates

Sydney Water Tanks have a range of engineer designed concrete pits that are suitable for a wide range of applications.

Rectangular Hollow Sections (RHS)

Our high quality, hot dipped galvanised RHS are suitable for council crossovers to connect the stormwater system to kerb gutter.
