About WaterLine

Trusted People. Trusted Tanks.

At Waterline, we have more than 30 years of experience in designing, manufacturing and delivering tanks of every shape and size to suit commercial, domestic, rural and industrial sites.

When it comes to choosing the right tank to collect rainwater, irrigate your gardens, supply water to your house, fulfil CFA requirements or to store water for stormwater detention, then you need a tank that’s not only designed and built to last, but one which will suit your specific site.

Here at WaterLine Tanks we also work with all tradespersons at every stage of the building process which include planners, architects, hydraulic engineers, plumbers, builders and landscapers. Below are some of the trades we commonly work with and supply water tanks to.

Waterline tanks were very easy to work with from start to finish. They pointed out and quickly reimbursed an overpayment I had made. They kept to their timelines, which is impressive these days. Their delivery man was polite and friendly - nothing was a problem. Thank you!

The kind and helpful staff from Waterline were very patient in assisting us to order the tank we needed and deliver to us on time, with all the extra parts ordered ready to go. The craftsmanship of the construction of the small tank exceeded all our expectations and the professionalism of every member of the organisation is to be congratulated!
