Septic Tanks

Klargester registered installer
Country Drainage was established in 1984.

Since then we have been installing septic tanks all over Kent as well as Sussex and Surrey.

A large percentage of Kent and Sussex is Wealden clay, however there are also large areas of chalk and broken sand stone. These areas are usually porous enough for the discharge from a septic tank or a sewage treatment plant to soak away into the subsoil. 

A porosity test will quickly determine the suitability of the sub-soil. This test will also enable us to calculate the size of soakaway required. However, in a great many cases visual annalise of the sub-soil is enough to determine the square meterage that will be required.

The liquid discharged from a septic tank is effectively raw sewage minus the solid matter.

The Environment Agency, therefore will only allow the discharge from a septic tank to soak into the sub-soil via perforated irrigation pipework laid in a shingle bed. 

We install these sewage treatment plants in the Tunbridge Wells area and outlying Kent villages including Brenchley, Matfield, Goudhurst, Cranbrook, Horsemonden, Paddock Wood, Biddenden and Benenden. We also cover theSussex and Surrey villages of Wadhurst, Hawkhurst, Ticehurst, Mayfield, Hurst Green, Robertsbridge, Heathfield, Battle, Uckfield, Buxted, Crowborough, Lingfield, Godstone, Oxted, Redhill, Reigate, and Horley.
