With Tanks in the range from 1800 to 20000 litres, there is an Atlantis PuraTank separator to suit most applications.

Wash down separators are used to remove dirty water from car washes or wash-down bays. The separator separates and retains silt, sediment and hydrocarbons before they enter the foul drain.

As well as being easy to install (due to their shallow design and high strength) these tanks benefit from a 10 year warranty.
