On paper, underground water tank installation isn’t complicated. You dig a hole, put the tank in, cover it up, and you’re done. Concrete tanks are preferred, because they last longer, and when you order them from Sydney Water Tanks, we give you a 30-year guarantee. We reinforce our concrete with steel, and there are no joints between the wall and the floor, making the tanks smoother, more stable, and reducing the risk of cracks and rust.

Our tank installation process begins with a free site evaluation. We’ll send our experts to your property. They’ll inspect your space, help you select an ideal location, guide you in style and sizing, explain the necessary steps, and give you a quotation. This essentially means your installation will require multiple visits, and that’s always easier when the weather is pleasant. This makes spring the ideal season for water tank installation. It’s warm and convenient for working outdoors, and work won’t be interrupted by summer showers.


Time factor

We currently have concrete tanks in four sizes ranging from 3,800 litres to 11,500 litres, all underground. We have options capacities beyond 12,000 litres – we’ll install and connect smaller tanks using steel RHS piping. They’re hot dipped and galvanised to prevent rust, and come in sections of nearly 6m. The steel is 4mm thick and measures 20cm by 10cm. The concrete tanks we design have cylindrical shapes and their lids are strengthened with steel, allowing them to support any weight placed above the tank’s surface.

They’re strong enough to sit beneath a parked car, so you can position it beneath the driveway, or even under a pool. Our experts can suggest the ideal location based on soil type, ease of excavation, natural landmarks, municipal restrictions, storm drains, or sewer systems. We pour your concrete tank onsite which means you’ll need two to seven days for your concrete to cure properly. This works better in warm dry, spring weather.


Following the rain

Australia exhibits a wide range of climatic conditions, from desert interiors in the outback to snowy mountain caps in Victoria. Most inhabited regions are coastal though, like Darwin, Sydney, and Perth. Tropical areas experience monsoon rains in winter, while beach-adjacent areas have a mostly dry year with showers in February and March. Both extremes are drier and more temperate during spring, making it a suitable time for working outdoors.

Digging and filling holes is back-breaking work, so as much as possible, plan to do it when the weather is more friendly. Also, most springtime activities involve cleaning and pool-building, so the demand for water tank installers is low. You can book early, and our installation team will work at your convenience. Having additional water storage can be useful for the coming summer. You’ll probably have friends and family over, so your water usage is likely to increase, and your tanks will help you lower your utility bills.
