Liner Tanks

Tank Liners Sydney by Raven Engineering Group sells and installs high-quality Colorbond liner tanks made in Australia. These tanks can store up to 350,000 liters of water and are ideal for rainwater harvesting, bulk dry goods storage, and other outdoor applications.

Liner tanks come in a kit with all the necessary solid galvanized steel fittings, trusses, and components. They are food-grade certified and can be assembled on virtually any foundation or base type, including sand, stone, gravel, and concrete.

The streamlined, lightweight design of liner tanks makes them easy to conceal or place inconspicuously for rainwater collection. They are also very durable and can withstand harsh outdoor conditions.

You Can Choose Between a Streamlined or Corrugated Finish for Your Tank

We offer two types of tank profiles, depending on your needs and preferences. Choose between a smooth, sleek finish or a channeled, grooved surface that is ideal for farming and agricultural environments.

High-Quality Gutters that are Innovative and Ahead of the Curve

Tank Liners Sydney by Raven Engineering Group offers an optional high-performance guttering system that can be installed with all of their liner tanks. This system directs 100% of the rainwater collected straight into your tank, reducing waste and increasing your emergency water reserves.

Installation - Important Information

While Tank Liners Sydney by Raven Engineering Group offers complete installation services for all new steel liner tanks, there are some minor preparations that the owner or site manager must still make.

Here is what we need to have prepared before installation day:

Prepare the base of the tank. The base should be a level, sand or concrete pad that meets the minimum thickness requirements. Please confirm the base specifications with us after placing your order.
Provide access to the site. Make sure there is enough space and access for our vehicles and equipment.
Be present on installation day. We recommend a brief on-site meeting before we start installation to confirm the exact placement of the new tank.
Provide a water supply. Make sure there is enough water available to fill the tank to about 20% of its capacity after installation.
