What is a Septic Tank?

A septic tank is a settlement chamber, which provides treatment to home sewage systems and drainage water. Overflow from the tank goes to a soakaway or drainage field.

Septic tanks can take the form of a 2 or 3 chamber tank. Older tanks (typically pre-1980) were usually brick or concrete. Pre-fabricated in a factory from glass-reinforced plastic (GRP). Spherical in shape with a neck, inlet and outlet pipes. Septic tank treatment must be carried out regularly, which may be a drainage field or reed bed.

Older septic tanks drainage sometimes did not conform to any Building Regulations. They may connect to a soakaway or even directly into a watercourse. These options are no longer acceptable. It is best to get the experts in to carry out domestic septic tank surveys, so you know if you need to upgrade.

Choosing A Home Sewage System

There are many factors to consider when looking into a new domestic septic tank. The size of the tank system required depends on a number of factors such as:

  • The number of bedrooms in a home

How Does a Septic Tank Work?

The purpose of a septic tank is to treat waste water from your property.

Traditionally it was a large rectangular box made of brick, stone or concrete. They are now normally a bottle-shaped plastic tank. They work like a simple waste water treatment works. The treated waste water drains from the tank’s outlet pipe to a drainage field.

The septic tank holds wastewater from the property and allows solid debris to settle at the bottom of the tank (the sludge layer). Lighter waste rises to the top to form the scum layer. Between the two layers lies clarified liquid. This flows into an outlet pipe and is gradually dissipated through a drainage field. Bacteria in the tank naturally break down organic waste matter and slow the build-up of the sludge layer.

The cost for septic tank repair in Lincolnshire is often covered by the existing insurance policies. We can advise you if this may be the case and handle the claim and rectification works if necessary. For this cover to apply it is not necessary to have separate drainage and plumbing insurance policies.

Septic Tank Emptying

  • The manufacturer will recommend desludging intervals. A septic tank is deemed ‘full’ when 35% of the interior space contains solid material, or sludge. The tank should always be full of water, which is what you will see if you open the tank.
  • The solid materials settle at the bottom of the tank and must eventually be pumped out. If the tank fills above 35% , there is a risk of solid waste entering the drainage field or clogging of the inlet to the tank.  Both of these situations can result in major problems and costly repairs.
  • These are guidelines only and in some case more frequent emptying is needed, for example: In an older system with an undersized tank used by a large family. This will require much more frequent pumping than a new system used by only a few people.
  • A failing system will require more frequent emptying.
