Types of Domestic Septic Tanks

The Alpha or Onion Shape Septic TankOnion shape septic tank

The Onion shape septic tank is the most commonly used septic tank style in the UK - because of their shape they are easy to install and maintain. All these tanks come with a full instruction manual on how to install and maintain in order to prevent bad odour and deterioration of the septic tank.  Most onion shape septic tanks should be installed with a concrete surround, unlike the cylindrical Tricel tanks which can be installed with a granular backfill.

GRP Cylindrical Low Profile Septic Tanks

This style of septic tank has a lower invert than most other septic tanks and a 40% lower profile than the onion shape alternative. Cylindrical septic tanks are suitable for installations in high water table areas or where the construction depth cannot be too deep, the cylindrical shape also makes this type of septic tank much easier to install.

Rotomold Cylindrical Low Profile Septic Tanks

Similar to the GRP type cylindrical septic tank these septic tanks have a very low profile but because of their strong plastic construction are ideal for DIY installations. These tanks are extremely lightweight, making them very easy to move into position without needing large machinery.
