Aquarius tanks featured on Grand Design Australia TV programme

Aquarius Watermaster was chosen to supply tanks for the Port Melbourne Urban Green Home. Featured on Grand Designs this home is clad in 34 black AQ2000L slimline rainwater tanks. These tanks will be used either as storage tanks or as planter boxes.

Eventually the facades of the building will be covered with an assortment of climbing and trailing plants, fed with water from the Aquarius tanks.

Latest design proves popular

The Aquarius 2000L Ultraslim is the latest tank in our range of slimline tanks and has already gained popularity due to its appearance and 470mm depth, the narrowest 2000L tank available.
