More Than Just a Manufacturer of Premium Water Tanks

Select Water Tanks manufactures hand-crafted steel water tanks … but we offer so much more. With many years in the rainwater harvesting industry we understand how your water tank works with the rest of the rain harvesting system.  We can help you choose the right pump and filtration for your circumstances. We can now offer both a variable speed pump and sophisticated filtration system in the one compact cabinet, Hybrid Housing Mk2.

Our steel tanks are fire resistant and can be fitted to be fire-fighting compliant.  Call one of our experts today on 07 5546 8571

Included fittings

Our water tanks come with three standard inclusions

  • A rainwater inlet on the top of the tank together with a hi-flow strainer to let water in and keep mosquitos out and a sunlight guard to keep out ultraviolet light to eliminate the growth of algae.
  • A 90mm or 100mm sized mosquito-proof overflow fitting at the top of the tank wall, directly under the lid
  • A 25mm outlet fitting together with a tested ball valve which is placed at the bottom of the tank.

We will ask you where you wish us to put these fittings

Our prices depend on

  • The material used to construct the water tank (Grade 304 stainless steel, Marine Grade 316 stainless steel or Aquaplate steel)
  • the shape of the water tank (round or slimline)
  • the size of the water tank by its dimensions
  • the distance from the factory for delivery
  • Additional fittings

Site and Delivery

There is a need to prepare the site where you intend to place the water tank(s).

There is a delivery charge depending on the distance from the factory. There is no additional cost for positioning the water tank on its pad provided if we can access the site easily. We can coordinate with a crane if a crane is needed.
