Septic Tank Problem in Essex Solved!

mantairtricel

Septic tank problems in Essex are common due to much of the county having a clay sub-strata.  Clay is mainly impermeable and as a result the effluent discharged to the receiving soakaway from a septic tank cannot drain away, resulting in the soakaway and septic tank having problems with surcharging.

The owners of this property, which is located on the outskirts of Colchester in Essex, had experienced septic tank problems since they moved into the dwelling in March 2014.  Unlike functioning septic tanks, it had been necessary to empty this tank on a monthly basis.

To determine the cause for the septic tank problems Mantair engineers carried out an internal inspection of the tank and conducted percolation tests to determine the porosity of the sub-strata.  The results of the inspection showed that the septic tank was in good structural condition with both inlet and outlet ‘dip pipes’ located.  The results of the percolation test showed that the sub-strata was unsuitable for a soakaway; this being the cause of the problems being experienced.

With the property having a watercourse on the boundary of the rear garden, Mantair engineers recommended that the septic tank be upgraded into a sewage treatment plant by installing a Biocel on the outlet of the existing tank.  Manufactured by Tricel, the Biocel septic tank conversion unit is designed to treat the receiving effluent from a septic tank and provides a treated effluent suitable for discharge direct to a watercourse.

Biocel-septic-tank-conversionessex-septic-tanks

The Biocel uses the existing septic tank as a primary settlement chamber whereby solids and floating matter are retained.  The remaining effluent passes from the septic tank and into the Biocel tank.  Within the Biocel are aeration and final settlement chambers.  The aeration chamber uses a Submerged Aerated Filter process whereby aerobic micro-organisms develop through the use of fine bubble aeration and plastic media.  Air is continuously supplied to the aeration chamber by a small air compressor (blower), which is housed remote from the Biocel tank.

Within the final settlement chamber fine solids are separated from the liquids.  The resulting treated effluent conforms to the required standard to be discharged to a natural watercourse.

The scope of the installation works included:

  • Installation of the Biocel within a suitably sized excavation, including for a concrete base and backfill;
  • Exposing the outlet from the existing septic tank and connecting this using drainage pipework to the Biocel sewage treatment unit;
  • Locating the air blower within a remote blower housing and provision of an RCD protected power supply to this point;
  • Installation of a new 110mm diameter discharge drain to the boundary watercourse;

On completion of the ancillary works, Mantair engineers commissioned the Biocel system.

Sewage Treatment Plant Installation in Bedfordshire

At this property in Bedfordshire we installed and commissioned a sewage treatment plant and soakaway / drainage field to replace a failed septic tank system.  The ageing septic tank had been causing problems for several years and the homeowners wanted to replace the tank with a modern sewage treatment plant as this would provide an effective and environmentally friendly way of disposing with their waste water.

After a detailed survey was conducted, Mantair engineers recommended the installation of six person Biosure packaged sewage treatment plant; this being in accordance with the British Water Flows and Code of Practice for sizing small sewage treatment plant.

excavationbiosure-sewage-treatment-plant

It was necessary for a new soakaway / drainage field to be constructed for the disposal of the treated effluent as no ditches or streams were available.  Prior to the design and size of the soakaway being determined it was necessary for ground tests to be carried out to determine the porosity of the ground.  The porosity of the ground in conjunction with the size of the sewage treatment plant determines if a soakaway will operate effectively, and if so, the size of soakaway required.

As with all sewage treatment plant installations Mantair conducts, the Biosure was installed with a concrete surround to protect the structural integrity of the tank.  An independent RCD protected power supply was installed from the property to the Biosure, with the relevant NICEIC Certification being obtained.

Prior to the project being completed the local Building Control officer inspected the works, approved all elements of the project and issued a Building Notice Certificate.

Sewage Treatment Plant Installation in Wendover, Buckinghamshire.

When the owners of a property located on the outskirts of Wendover in Buckinghamshire were advised by the Environment Agency that their septic tank was illegally discharging into a watercourse, they called on the services of Mantair to provide a solution.

As with all enquiries of this nature, we arranged for an engineer to attend site and carry out an inspection of the existing drainage arrangements and site conditions.  Due to the ground conditions being unsuitable for a soakaway system it was necessary for the discharge to the watercourse to continue.  With the existing septic tank being unsuitable for the installation of a Mantair septic tank conversion unit, it was necessary to install a packaged sewage treatment plant, which would produce a treated effluent in compliance with the Environment Agency’s.

sewage-treatment-plants-bucks

With the property having five bedrooms, we recommended, in accordance with the British Water Flows and Loads Code of Practice, the installation of an eight person sewage treatment plant.  To ensure the visual impact to the garden was kept to a minimum we installed a Tricel sewage treatment plant with remote Beehive blower housing.

Prior to any ancillary works commencing, Mantair engineers scanned the proposed location of the new sewage treatment plant and areas where any excavations were taking place to ensure that no underground services were present.

As part of the project we liaised with the Environment Agency and the local Building Control department to obtain the relevant approvals for the installation.

Tricel

The scope of the installation works included:

  • Exposing the existing foul drainage pipe work and diverting to the location of the new Tricel sewage treatment plant;
  • Installation of the sewage treatment plant in a suitably sized excavation, including for a concrete base and backfill;
  • Locating the air blower within a Beehive blower housing – a purpose built housing designed to blend into the natural surroundings;
  • Provision of an RCD protected power supply to the Beehive housing;
  • Installation of the air main from the air blower to the Tricel sewage treatment plant;
  • Installation of a new 110mm diameter discharge drain to the roadside ditch;

On completion of the ancillary works, we commissioned the Tricel sewage treatment plant, including setting of air valves, checking all pipe work joints and viewing the discharge into the final discharge chamber.

Septic Tank Problem in Hertfordshire

As a leading ‘off mains’ solution provider throughout Hertfordshire and surrounding Counties, we have seen a substantial increase in the number of calls relating to the replacement of failed septic tanks with modern packaged sewage treatment plants throughout 2014.  This is partly due to the winter storms of early 2014 causing much of the Country to receive excessive amounts of rainfall, resulting in flash flooding and a rising water table.  The rising water table and saturated ground conditions caused many septic tank soakaways to fail.

We were contacted by the owner of a property on the outskirts of Stevenage in Hertfordshire after they had experienced several months of their septic tank flooding in early 2014.  The homeowner wanted to replace the existing septic tank and drainage field with a system that would operate effectively throughout the winter months.

Upon inspection, it was found that the foul drainage from the property to the existing tank was in good condition with no fractures or dislodged joints.  Located on the boundary of the rear garden was a field ditch which would provide a suitable location for the disposal of treated effluent.

Mantair engineers recommended the installation of a packaged sewage treatment plant and remote Beehive blower housing.  The treatment plant was installed with a ‘pumped’ outlet ensuring that the system would operate effectively even if the receiving ditch became flooded during periods of heavy rainfall.

Throughout the duration of the works Mantair engineers ensured that the impact on the garden was kept to a minimum.

Septic Tank Installation in Woodbridge, Suffolk

Mantair was contacted by the owner of a property located on the outskirts of Woodbridge in Suffolk regarding septic tank problems.  The homeowner requested the services of Mantair to assist in the replacement of the ageing septic tank.

On inspection, it was found that the tank was constructed from brickwork 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 collapsed. 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 tank was functioning correctly.  With the soakaway system working effectively and the cause of the problem being with the septic tank itself, Mantair engineers 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.

Sewage Treatment Plant Installation, Cooksmill Green, Chelmsford, Essex.

At this property in Essex we installed and commissioned a sewage treatment plant to replace a failed septic tank system.

Mantair was contacted by the owner of a property located in the hamlet of Cooksmill Green, near Chelmsford in Essex.  The homeowner requested the services of Mantair to assist in the modernisation of a septic tank system.

On inspection of the foul drainage system it was evident that the existing septic tank discharged directly into a nearby roadside ditch.  On viewing the internal condition of the septic tank is was apparent that the structural integrity of the tank was impaired.

Using the Geological Survey Map of the Chelmsford area, Mantair engineers were able to determine that the underlying sub-strata was predominately clay.  With the ground conditions being impermeable a replacement septic tank soakaway system would not operate correctly as the discharged liquids would be unable to percolate through the sub-strata.

sewage-treatment-plant-chelmsford

Mantair recommended that the septic tank be replaced with a packaged sewage treatment plant, which would provide suitable treatment so that the final effluent would be acceptable and in accordance with the Environment Agency’s requirements for discharge to the roadside ditch.

After discussing the clients concerns and requirements it was paramount that the new sewage treatment plant was both quiet and had minimal maintenance requirements.

Following the initial site survey and subsequent discussions with the client, Mantair recommended in accordance with the British Water Flows & Loads Code of Practice, the installation of a six person Tricel sewage treatment plant with Medo air blower.

As part of the project Mantair liaised with the Environment Agency and the local Building Control Department to obtain the relevant approvals for the installation and the discharge to the roadside ditch.

Prior to any ancillary works commencing Mantair engineers scanned the proposed location of the new sewage treatment plant and areas where any excavations were taking place to ensure that no underground services were present.
