Safe below the ground storage with Septic Conservancy Tanks

Septic tanks are a key on-site sewage facility. They are utilised in scenarios where a property is not connected to municipal sewage system and are erected underground for safety purposes. As a result septic tanks are not portable after installation.

Although they are installed underground, they also come with an 8 year UV protection and 5 year structural warranty. Septic tanks are only available in black.

RotoTank™ also offer the option of a French Drain solution for easy maintenance, durability and cleanliness. This option is available should you have a smaller area and want the ability to clean through manhole access. Utilising French Drains enables you to maximise your tanks storage capacity.

The term “septic” refers to the anaerobic bacterial environment that develops in the tank. Once bacteria has developed, it decomposes the waste and is discharged into the tank. Sewerage waste that is not decomposed by the anaerobic digestion, might have to be removed from the tank. If this process is not done, the septic tank continues to fill up may over flow.

Disposing of oils, chemicals or any other unnatural waste is not advised as this may block the septic tank or disturb the bacterial breakdown of the septic sewerage system. Septic tank treatment is an easy and low maintenance way to deal with waste.

Please bear the following in mind when installing your RotoTank™:
  • Base of tank must be positioned on solid, level grounding which is free of any protruding objects which could lead to puncturing the 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.
  • Activation of the tank can either be initiated by use of a biological activator or alternatively using some rotting or discarded meat from a local source eg your kitchen or a butchery.
