What size waste tank do you need?

This is a difficult question to answer as it is dependent on a lot of different factors but a key thing to remember is that the main cost associated with a tank will be the emptying of it and it will be cheaper in the long run if you have a larger waste tank at site. 

However you may be limited by space and our largest 1000 gallon tank is much taller than the 500 gallon so that is also a consideration.

Most sites find that a 500-gallon tank is a good solution to capture waste from a toilet block as long as the levels are monitored and a regular empty is carried out.

Why Plastic tanks rather than steel ?

  • They will not corrode - no matter how long they are in use. Leaking rusty tanks are a thing of the past
  • They are much lighter than steel tanks (120-140 kgs compared with 420 kgs for a500-gallon tank)
  • Lighter Tanks reduce environmental impact: by reducing fuel use in transport
  • You can Deliver and position Plastic Tuff Tanks with far less effort, heavy equipment and expense than steel tanks
  • Plastic Tuff Tanks are easy to clean and maintain a hygienic image
