Fully installed sewage treatment plants in Ashford Kent

G.M.C are experienced in the preparation and installation of sewage treatment systems in Ashford Kent, our team hold all of the necessary qualifications to install and commission sewage plant systems.

A sewage treatment system is an efficient, stand-alone, below ground sewage treatment system. sewage treatment systems are mainly found in rural areas where there is a larger distance between houses.

In such areas sewage treatment systems are generally more economical to install and maintain than traditional main drainage systems, this is because unlike main drainage systems wastewater is processed on-site, which in turn means there is no need to install additional sewer lines to connect the home to the mains sewer system.

We install sewage treatment systems in Ashford, Tenterden, Folkestone, Canterbury, Maidstone, Tenterden, and all surrounding villages.

Sewage treatment systems in Ashford Kent how do they work?

Made up of two parts the tank and a drain field. A sewage treatment system is crudely a sealed box and is normally made of either fibreglass or concrete with a fixed inlet and outlet pipe.

Wastewater runs from your house into the box via the connected sewerage pipe. The tank itself then goes about treating the wastewater, the sewage tank holds the wastewater long enough for liquids and solids to separate into three layers any solid lighter than water floats to the top of the tank, any solid heavier than water sinks to the bottom of the tank, the middle layer is partially clarified wastewater. this is a perfectly natural process and happens without intervention.

Naturally occurring bacteria found in the wastewater of the sewage tank get to work breaking down the bottom and top layers of solids. Any sludge, scum or solid that is unable to be broken down is retained in the sewage tank until it is emptied. The layer of partially clarified liquid flows from the sewage tank into the drain field or a distribution device.

The clarified wastewater is then distributed to trenches lined with sand or other coarse materials which act as a second biological filtration system the wastewater is efficiently distributed by perforated pipes lining the trenches.

The filtered wastewater is then finally absorbed by the soil. The standard system used to do this is known either as a leach field, soil absorption system or disposal field.

Protecting your investment

  • It is important not to drive cars or heavy machinery over the absorption field area
  • No plants or trees should be planted in the absorption area, roots have the potential to grow into the lining and cause blockages
  • The absorption field should only be covered with grass as it will help remove any excess water. Patios concrete or paving are not suitable coverings
  • Excess water from any other area of your home should not be diverted to the absorption field
