Septic Tank Maintenance

A septic tank is a type of biological sewage treatment system, a private sewage treatment plant receiving all waste water from your house. Naturally occurring bacteria break down the solid matter, reducing its volume. The liquid element is discharged usually via effluent drainage systems "soakaways". The accumulated solids need only be pumped out occasionally (annually for a family of four).

We have produced a series of Factsheets to help our customers to understand how their system works.

Glanville Environmental will empty your septic tank for you and take the waste away to be treated safely. The company also installs septic tanks and bio-treatment plants and removes old septic tanks.

Your septic tank relies on the action of micro-organisms in order to break down the raw sewage.  A little sludge is always left in the tank as this contains the bugs necessary to get your system working as soon as possible.  The water level in the tank will quickly rise to its normal working level.  This can occur within a few days of the sludge being emptied.   Glanville Environmental also have a 24hour emergency service for an overflowing or leaking septic tank, meaning we will be out to you as soon as possible, day or night, to solve the problem.

The Duchy of Cornwall use our septic tank service and regard us as "a very valued contractor."
