Alpha Septic TankCase Study
Septic Tank Installation in Suffolk.

Location – Woodbridge, Suffolk.

Mantair Contracts Division was contacted by the owner of a property which was located on the outskirts of Woodbridge in Suffolk, regarding their septic tank problems.  The homeowner requested the services of Mantair to assist in the replacement of their collapsing septic tank.



On inspection of the existing septic tank it was found that the tank was a traditionally built brick tank, and that the walls of the tank had started to collapse.  One side of the septic tank had completely lost its structural integrity with much of this side of the tank having fallen into the tank.  The main reason for the septic tank failure was due to sulphate corrosion.

From the initial septic tank survey it was evident that the existing soakaway system connected to the septic tank was functioning correctly.

It was decided that the existing septic tank area would be sealed off to prevent any persons from gaining access around the area of the tank.


With the soakaway system working effectively and the cause of the problem being with the septic tank itself, Mantair recommended replacing the existing failed septic tank with a modern replacement septic tank.

As part of the project Mantair liaised with the Environment Agency to obtain an Exemption Certificate, and the local Building Control Department to obtain the relevant approvals for the installation.
