Septic Tank Conversion – Suffolk

We were contacted by the owners of a Cottage in the village of Sproughton near Ipswich, with a view to resolving the problems being experienced with their septic tank overflowing to a nearby ditch.

After discussing the problems being experienced by the homeowner, we arranged to carry-out a free site inspection. Upon inspection, it was found that the property drained to a ‘brick built’ septic tank located in the front garden of the property.  On internal inspection of the septic tank it was found that the septic tank was in good structural condition and had an operating capacity of approximately 3500 litres.

As a result of the septic tank discharging to a nearby ditch there was high levels of ‘untreated’ effluent polluting the watercourse, causing a potential health risk.  A discharge of this type from a septic tank contravenes the Environment Agency’s General Binding Rules.

With the existing septic tank being in good structural condition and sufficient capacity, we recommended the installation of a septic tank conversion system.  The Mantair conversion unit is specifically designed to fit within an existing septic tank or cesspool, effectively ‘converting’ the existing tank into a small sewage treatment plant.  The treated effluent produced from the Mantair unit complies with the requirements of the Environment Agency for discharge to a natural watercourse.

The installation of the Mantair septic tank conversion unit saved the homeowners thousands of pounds when compared to other quotations they had received for the installation of packaged sewage treatment plants. The installation of the Mantair system also caused minimal disruption to the garden as no heavy machinery was required to carry-out the project.

Mantair provides a comprehensive septic tank and sewage treatment plant service.  This includes free site inspections, guidance and advice on the most suitable system for the client’s requirements, complete installation, commissioning and full after sales care.

Sewage Treatment Plants Suffolk

When the owners of a property in the rural hamlet of Depden Green near Bury St Edmunds in Suffolk needed a new sewage treatment plant, they called on the expertise of Mantair to provide an economical and reliable sewage treatment solution.

As Suffolk’s leading installer of sewage treatment plants, Mantair has installed waste water treatment solutions throughout the majority of villages and hamlets around Bury St Edmunds, including various installations on the National Trust’s Ickworth Estate.

At this Suffolk dwelling the existing septic tank system had failed, causing the drainage from the property to surcharge, leaving the homeowners with the expense of having their septic tank emptied on a weekly basis. It was the homeowners preference to have the existing tank replaced with a modern sewage treatment plant.

With the property having three bedrooms, Mantair engineers recommended in accordance with the British Water ‘Flows and Loads’ Code of Practice – 4, the installation of a six-person Clearwater sewage treatment plant. The effluent produced from the Clearwater system is clean enough to discharge directly into a natural watercourse. It was therefore agreed that the treated effluent would discharge into a boundary ditch.

Due to the receiving ditch not being maintained for several years it was necessary for the ditch to be graded prior to the installation of the Clearwater sewage treatment plant. Using ‘euro-mats’, Mantair engineers constructed a temporary protective pathway in the garden to ensure that the required machinery wouldn’t cause any damage to the lawn.

After the works on the boundary ditch were complete, Mantair engineers started on the installation of the sewage treatment plant. As with all underground septic tank and sewage treatment plant installations Mantair carries out, the tank was completely encased in concrete to ensure the structural integrity of the tank is not impaired and to prevent the potential of flotation.

Scope of the installation works included:

  • Exposing the existing foul drainage pipework and installation of new drainage to the Clearwater sewage treatment plant;
  • Complete installation of the Clearwater treatment plant in a suitably sized excavation and back-fill;
  • Installation of the Secoh air blower within a remote blower housing and provision of an RCD protected power supply;
  • Installation of the air main from the blower housing to the Clearwater sewage treatment plant;
  • Installation of the pumping main from the Clearwater system to the boundary ditch, including for the installation of an inspection chamber.

Damaged Septic Tank

When a septic tank is damaged and in need of repair or replacement, it can be very costly for the property owners affected, with costs often running into thousands of pounds. In certain situations, the buildings insurer for the property should provide cover for the costs to repair or replace the damaged septic tank.

However, we often see instances of insurers or loss adjusters not making the right decisions on damaged septic tank claims. This can result in valid claims being turned down, or the wrong type of works being undertaken. In claims that we have successfully been involved with, we have noticed as many as 1 in 3 claims being incorrectly turned down, or the scope of works being incorrectly approved in the first instance. Mantair works in partnership with UKDP, to offer a unique insurance claims management service for our clients to ensure the correct drainage solution is approved by the insurers.

At this property in Suffolk, the septic tank was damaged due to ground movement and was in need of replacement. Acting on behalf of the homeowner and in association with UKDP, Mantair engineers were able to obtain approval for the replacement of the damaged septic tank under the household insurance policy.

Although the insurers wanted to replace the damaged system with a new septic tank and soakaway this was not possible as there was insufficient land available for the required soakaway. It was therefore agreed that the damaged septic tank would be replaced with a modern packaged sewage treatment plant, producing a treated effluent which would be discharged to a boundary watercourse.

septic-tank-insuranceground-protectionconcrete

The chosen sewage treatment plant was a six-person Biosure system which was installed underground with only a manhole cover at ground level. Prior to works commencing, Mantair engineers installed a euro-mat ground protection system to ensure that the impact on the garden was kept to a minimum.

With the new sewage treatment plant having minimal impact on the garden setting, Mantair engineers recommended the new system was installed adjacent to the damaged septic tank, thus reducing the amount of excavations required.

excavation-for-sewage-treatment-plantmantairsewage-treatment-plants-suffolk

As with all new underground tank installations, the new sewage treatment plant was installed at a depth to ensure the existing foul drainage from the property could gravitate to the new system. It was necessary for the new sewage treatment plant to have an inlet invert depth of 750mm.

Once the sewage treatment plant was in position the tank structure was completely encased in concrete.  Thus ensuring that the tank structure was protected from flotation ground pressure.

On completion of the ancillary works, Mantair engineers commissioned the sewage treatment plant, including setting of air valves, checking all pipe work joints and viewing the discharge into the boundary watercourse.

All machinery was removed from site and the garden was left in a neat and tidy manner with no evidence of disturbance to the garden setting.

Sewage Treatment Plant Project in Suffolk

Sewage treatment plants are becoming more popular in Suffolk as they provide homeowners with a modern alternative to septic tank systems. As leading independent installers and service providers for sewage treatment plants in Suffolk, Mantair is ideally placed to provide Suffolk homeowners with a sewage treatment plant to meet their site requirements, or provide the expertise required for assessing septic tank problems.

Mantair has been providing a professional service for sewage treatment plant installations throughout Suffolk for over 20 years, with all projects being carried out in accordance with Environment Agency Regulations and Section H2 of Building Regulations.

sewage-treatment-plant-installers-suffolk

At this location in Suffolk it was necessary for a failed septic tank to be replaced with a sewage treatment plant installation.  The existing septic tank served a pair of semi-detached cottages located at Darsham in Suffolk.

Mantair was originally contacted by one of the homeowners regarding a complaint they had received regarding the effluent from their septic tank causing pollution in an adjacent field.  Upon inspection, it was evident that untreated effluent was collecting in a depressed area of the adjacent field, causing a serious health hazard.

The existing septic tank was constructed from brickwork.  During the septic tank survey Mantair engineers identified that the septic tank had been damaged and was not functioning correctly, resulting in untreated effluent passing through to the receiving soakaway.  It is most likely that the damage to the septic tank was the cause for the soakaway failure.

Mantair engineers have a wealth of experience in dealing with damaged drainage systems, and the damage to the septic tank at this location was considered to be consistent with accidental damage.  Working in association with UKDP (UK Drainage Claims Ltd), we were able to obtain approval for the costs for the new sewage treatment plant installation to be covered by the homeowners Insurance Policys; this saving the homeowners thousands of pounds.

mantairsewage-treatment-suffolksewage-treatment-specialists-suffolk

With each of the cottages having three bedrooms, we recommended, in accordance with the British Water Flows and Loads Code of Practice – 4, the installation of a ten person Tricel sewage treatment plant.

Due to the site restrictions it was necessary for the Tricel sewage treatment plant to be installed within a paved area.  To ensure the visual impact on the garden was kept to a minimum we installed the air blower for the system remotely from the tank.  As a standard, the air blower and housing supplied with the Tricel system is located on the top of the tank.

excavation sewage-treatment-plants-suffolk tricel-sewage-treatment-plant

Due to the depth of the existing foul drainage, it was necessary for the tank excavation to be three metres deep.  The quality of effluent discharged from the Tricel sewage treatment plant is clean enough to drain directly into a natural watercourse, and at this location in Suffolk we discharged the treated effluent into a roadside ditch.  With the drainage from the cottages being deeper than the depth of receiving ditch, it was necessary for the Tricel sewage treatment plant to have a ‘pumped’ outlet.

Prior to any ancillary works commencing, Mantair engineers scanned the proposed location of the Tricel 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.

Septic Tank Problem in Suffolk Solved!

After years of putting up with septic tank problems the owners of a property at Halesworth in Suffolk, decided enough was enough!  They were advised to contact Mantair by their tanker company to resolve the septic tank problems.

septic-tank-problems

From our initial telephone discussions, it was evident that a site visit was required to ascertain the reasons for the septic tank problems.  On inspection, it was found that the septic tank was completely surcharged due to the soakaway failing.  On emptying of the septic tank it became apparent that the internal baffle within the tank had become dislodged, thus preventing proper separation to take place within the tank.  As a result, solids and fat had passed into the soakaway field causing it to fail.

With the tank no longer able to function as a septic tank it was decided to ‘convert’ the existing tank with a Mantair septic tank conversion unit, thus converting the tank into a small sewage treatment plant.  With no watercourse being available for the disposal of the treated effluent and this area of Suffolk being on a permeable sub~strata, Mantair engineers recommended the construction of a new ‘high level’ soakaway / irrigation field.  As with all soakaway / irrigation systems, it was necessary for Mantair engineers to carry out Percolation Tests to determine the porosity of the sub-strata and to obtain the size of soakaway / irrigation field required.

One of the key benefits of installing a Mantair septic tank conversion unit is that it fits within the existing tank removing the need for a new tank to be installed.

Apart from the financial savings of installing a Mantair conversion unit when compared to the installation of a packaged sewage treatment plant, the disturbance to the garden at this Suffolk property was kept to a minimum.

Sewage Treatment Plant Installation in Suffolk – National Trust

Sewage treatment plants offer Suffolk homeowners with a modern alternative to septic tank systems for areas not serviced by mains drainage. As leading independent installers and service providers for sewage treatment plants in Suffolk, Mantair is ideally placed to provide Suffolk homeowners with a sewage treatment plant to meet their site requirements, or provide the expertise required for assessing septic tank problems.

national trust mantair

Located on the National Trust’s Ickworth Estate near Bury St Edmunds in Suffolk, in an area of outstanding beauty is “The Roundhouse”.  After the renovation of the property Mantair were appointed by the National Trust as the preferred contractor to provide a design, installation and commissioning service for the upgrading of an ageing septic tank serving the property.

Mantair engineers carried out a detailed survey of the location to determine the ground conditions of the site and to evaluate the position of underground services.  The results of a Percolation Test showed the sub-strata to be impermeable and that a replacement septic tank soakaway system would not operate effectively.

After considering all the various options for foul drainage disposal and the size of the property, Mantair recommended the installation of a six – person sewage treatment plant with a discharge direct to a nearby watercourse.  It was important that the chosen treatment system was installed below ground to ensure there was no visual impact on the properties surroundings.

suffolk sewage treatment plant installsewage-treatment-plant-installers-suffolksewage-treatment-plants-suffolk

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 of the sewage treatment plant and the discharge to the nearby watercourse.

Taking into account all of the site requirements, Mantair recommended the installation a Tricel sewage treatment plant with MEDO air blower.

As with all underground septic tank and sewage treatment plant installations Mantair carries out, the tank was completely encased in concrete to ensure the structural integrity of the tank is not impaired and to prevent the potential of flotation of the tank.

The installation of the sewage treatment plant included:

  • Exposing the existing foul drainage pipe work and diverting to the location of the new Tricel sewage treatment plant;
  • Installation of the Tricel sewage treatment plant in a suitably sized excavation and back-fill;
  • 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 receiving watercourse, including for the installation of a headwall;
  • Backfilling all excavations and leaving the area neat and tidy.

On completion of the ancillary works Mantair 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.

After all works were completed at this Suffolk location, Mantair provided the National Trust with a Maintenance Agreement providing a full after care service for the newly installed sewage treatment plant.

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.

Orford Ness Nature Reserve, Suffolk – Sewage Treatment Plant Installation.

orfordness ordfordness suffolk sewage plant

Orford Ness is a 10 mile shingle spit of land off the Suffolk coastline and is separated from the mainland by the River Ore.  Orford Ness is the largest vegetated shingle spit in Europe and is both a Site of Special Scientific Interest (SSSI) and is also a RAMSAR Site.

Top secret military testing was carried out at this designated Outstanding Area of Natural Beauty during both World Wars and Orford Ness was home to both the Ministry of Defence’s Experimental Flying Research Station, and after World War 2, the Atomic Weapons Research Establishment.

Orford Ness in Suffolk is now owned by the National Trust and is open to the public for parts of the year.  Due to an ineffective septic tank soakaway system serving the waste water facilities on the Ness, the National Trust asked Mantair to investigate and provide a solution to the problem, taking into account the wide variation in waste water flow between winter and summer months.

Prior to the design element of the project, Mantair carried out a full site investigation including a detailed land survey for unexploded ammunitions and underground services.  Following the various preliminary site surveys, Mantair liaised with the Environment Agency, English Nature and Suffolk Coastal District Council regarding the project to determine an acceptable wastewater treatment solution.

orfodness mantairsewage treatment plant installation

Taking into account that Orford Ness is an internationally important site for nature conservation, the Environment Agency and English Nature accepted Mantair’s waste water treatment proposal which comprised two sewage treatment systems and a flow splitting chamber which allows the flow to be diverted to either of the two systems.  For low season during winter, a Mantair septic tank conversion system was fitted within the existing septic tank, converting the tank into a fully functioning sewage treatment plant.  In summer the Ness is open to the public and the waste water flow increases substantially.  A 42PE Tricel packaged sewage treatment plant was installed to cater for the increase in flow during summer.

The Orford Ness project in Suffolk posed significant challenges to Mantair engineers as there is still dangerous debris buried on the Ness, including bombs, and the only access onto Orford Ness is from Aldeburgh along shingle beach on a Unimog vehicle, or from Orford Quay on a landing craft.  Timing was also crucial on the project as the water table on the Ness is affected by the tide and all excavations had to be carried out within a certain time frame.

Despite the complexity of the Orford Ness project, the pre-planning and experience of the Mantair engineers ensured that the project was completed efficiently and without any problems.
