Safe underground storage

Underground Storage Tanks are a key Liquid Storage Facility and are accessible via a manhole. They are stored below the ground for safety purposes and as a result are not portable once installed buried as an underground fixture.

Due to the storage tanks being underground the thickness and well as heavy duty access points allow for peace of mind. They come with an 8 year UV protection should your tank only be installed underground at a later stage and 5 year structural warranty on the extra heavy duty technology.

Bear following in mind when installing an underground RotoTank™ tank:
  • Base of tank must be positioned on solid, level grounding which is free of any protruding objects which could lead to puncturing the underground storage tank
  • Imperative to follow installation instructions
  • Weight and quality specifications are recorded for your benefit – ensure that you get the right product for the task at hand.
  • Avoid top and lateral loaded stresses. Reinforce top soil with beams where possible
  • Excavated hole must be of correct size and shape of the buried tank concerned
  • A RotoTank™ French drain is an optional addition to your assembly and to be used in conjunction with the septic/conservancy underground tank
