Off Mains Drainage Solution

Off mains drainage solutions can be varied and are mainly determined by the site conditions and applicable regulations. Off mains drainage systems can be in the form of a cesspool, septic tank, septic tank conversion unit or packaged sewage treatment plants.

With many developments in recent times being beyond the reach of ‘mains drainage’, the number of properties requiring an ‘off mains’ drainage solution has increased substantially. When an ‘off mains’ drainage system is the only option then the first choice should always be to install a sewage treatment system. This was highlighted by the DETR report which recommends septic tanks should only be considered if a sewer connection or sewage treatment system cannot be used.

An example of a sewage treatment plant installation is below.

At this property the ‘brick’ septic tank was struggling to cope with the flow being produced by the household, resulting in the receiving drainage field / soakaway surcharging. It was agreed with the client to replace the failing system with a modern Tricel Novo sewage treatment plant.

Tricel Novo sewage treatment plants are Certified to European Standard EN12566-3. By providing a safe environment for the collection and treatment of waste water, the Tricel Novo system produces a mostly clear, odourless treated effluent suitable for discharge direct to a watercourse or drainage field / soakaway.

  

With the new Tricel Novo system being installed in a more secluded part of the garden, it was necessary to excavate the existing foul drainage from the property and install new foul drainage to the location of the Tricel system, which included the lifting and reinstatement of a patio.

As with all septic tank and sewage treatment plant installations we execute, the Tricel Novo system 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 Tricel system, with the relevant NICEIC Certification being obtained.

A new discharge drain was installed and connected to the Tricel system allowing the treated effluent to drain directly into a nearby ditch. The existing septic tank was de-commissioned and in-filled.
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 East Anglia

Sewage Treatment Plant installations in East Anglia can overcome the majority of problems associated with septic tank failures where ground conditions are not suitable for soakaways.  As the sub-strata in parts of East Anglia is predominantly Boulder or London Clay, both of which having poor permeability values, soakaway failures are commonplace.  Within these areas of East Anglia a sewage treatment plant installation would allow the treated effluent to be discharged direct to a ditch or stream, removing the need for a soakaway.

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

Case Study

At this location in East Anglia it was necessary for a failed septic tank to be replaced with a modern sewage treatment plant installation. The existing septic tank served a detached property in the hamlet of Cutlers Green near the town of Dunmow in Essex.

Mantair was contacted by the homeowner regarding the foul drainage from the property surcharging.  Upon inspection, it was found that the septic tank was flooding; this causing the foul drainage to surcharge.

The existing septic tank was constructed from two ‘concrete ring’ chambers. During the septic tank survey Mantair engineers identified that the tank had been damaged and was not functioning correctly, resulting in untreated effluent passing through to the receiving soakaway.  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.  The damage to the septic tank at this location was considered to be consistent with accidental damage. Mantair were able to obtain approval for the costs for the new sewage treatment plant installation to be covered by the homeowners Insurance Policy; this saving the homeowner thousands of pounds.

mantairground-protectiondomestic-sewage-treatment-plant-essex

Based on the property having five bedrooms and in accordance with the British Water Flows and Loads Code of Practice -4, an eight-person Tricel Novo sewage treatment plant was installed.

The Tricel Novo sewage treatment plant is a ‘single tank’ system incorporating an aeration chamber, where masses of naturally occurring bacteria inhabit specially designed filter media. These bacteria are sustained with air, which is continuously supplied from a air blower. As the liquid flows slowly through the filter media, the bacteria feed on the waste and remove it from the liquid. The level of treatment within the Tricel Novo is far superior to that of a septic tank and complies with the requirements of the Environment Agency for discharge direct to a natural watercourse

The scope of the installation works included:
  • Exposing the existing foul drainage pipe work and diverting to the location of the new Tricel Novo sewage treatment plant;
  • Installation of the sewage treatment plant in a suitably sized excavation, including for a concrete base and backfill;
  • Provision of an RCD protected power supply to the sewage treatment plant blower housing;
  • Installation of a new discharge drain to the boundary ditch;
  • De-commissioning and filling-in of the failed septic tank;
  • Backfilling all excavations and leaving the area neat and tidy.

Septic Tank Problem in Surrey

After moving into a property with septic tanks problems in Surrey the new homeowners needed to find a waste water solution to replace a failed septic tank. The homeowners were recommended to contact Mantair to resolve their septic tank problems. Providing free site assessment visits, Mantair can assess all septic tank problems in Surrey.

septic-tank-problems-surryfailed-septic-tank-surrey

After a brief telephone conversation with the client it was evident that a site inspection was required to ascertain the cause for the septic tank problem.  Upon inspection, it was found that the septic tank was surcharged and causing the foul drainage from this Surrey property to ‘back up’.  On emptying of the septic tank it became apparent that the internal baffle within the tank had collapsed, thus preventing proper separation to take place within the tank.  As a result of the septic tank baffle collapsing, solids and floating material had passed into the soakaway drainage field causing it to choke.

With the tank not being able to function as a septic tank and the clients preference to have a new tank installed in the front garden, Mantair engineers recommended the installation of a six person Tricel sewage treatment tank; this being based on the property having four bedrooms and in accordance with the British Water Flows & Loads Code of Practice.  The Tricel tank is a ‘one piece’ packaged sewage treatment plant and is designed to produce a final treated effluent suitable for discharge to a ditch, stream or river.

mantairseptic-tanks-surreysewage-treatment-plants-surrey

Mantair engineers scanned the ground to identify all underground services prior to works commencing.  With the existing septic tank being positioned in the rear garden it was necessary to divert the foul drainage to the location of the new Tricel plant in the front garden. The majority of septic tank and sewage treatment plant installations require deep excavations and trenching for new drainage pipes. Therefore, it is crucial that all underground services are identified and remain undamaged throughout the duration of excavations.

As with all septic tank and sewage treatment plant installations Mantair conducts in Surrey, the Tricel plant 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 Tricel, with the relevant NICEIC Certification being obtained.

cesspits-surreymantair-surrey

A new discharge drain was installed and connected to the Tricel plant allowing the treated effluent to drain direct into a nearby ditch. The existing septic tank was de-commissioned and infilled.

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.

The installation of the Tricel sewage treatment plant solved the septic tank problems at this Surrey location and provides the homeowners with an environmental way of disposing with their waste water.

Damaged Sewage Treatment Plant in Surrey

For sewage treatment plant and septic tank installations in Surrey, Mantair provides with a complete design, installation and commissioning service.

Throughout rural areas of Surrey many property are not serviced by “mains drainage” for the disposal of waste water. As leading independent installers of sewage treatment plants and septic tanks, Mantair is ideally placed to provide Surrey home and business owners with a sewage treatment system to meet their budget and site requirements, or provide the expertise required for solving septic tank problems.

Case Study – Guildford, Surrey.

broken-sewage-treatment-plantair-blower

We were approached by the owner of a small business park in Surrey regarding a broken sewage treatment plant and the problems being experienced with the foul drainage system serving the park.

After lengthy discussions with the client it was apparent that the existing sewage treatment plant had failed and was causing pollution in a nearby watercourse. Mantair engineers recommended a site inspection be carried out to determine the cause for the sewage treatment plant failing.

Survey & Design

On inspecting the existing sewage treatment plant Mantair engineers identified that the plant incorporated a biological filter. The biological filter is designed to promote the growth of aerobic micro-organisms which ‘treat’ the sewage. After emptying the sewage treatment plant it was evident that the biological filter had collapsed, and as a result, no treatment was occurring within the tank.

Recommendations

It was decided to replace the failed sewage treatment plant with a new treatment system, which would be located in a more discreet area of the park.

tricel-sewage-treatment-plantmantair-sewage-treatment-plantssewage-solutions

Taking into account all of the site requirements, Mantair engineers recommended the installation a 24PE Tricel sewage treatment plant with remote blower housing at this Surrey location.

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.

Installation

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.

At this property in Essex we installed and commissioned a sewage treatment plant to replace a failed septic tank system. The ageing septic tank had been discharging to a watercourse for several years and the homeowners wanted to replace the tank with a modern sewage treatment plant.

septic-tank-problems-essexseptic-tanks-essexessex-septic-tanks

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

Due to the site restrictions and to minimise the disturbance to the garden it was decided to install the new sewage treatment plant in the same location as the existing septic tank. This required the removal of the septic tank concrete cover slab and internal brick partition wall.

septic-tank-experts-essexconcrete-basemantair

As with all sewage treatment plant installations Mantair conducts, the Tricel Novo sewage treatment plant was installed with a concrete surround to protect the structural integrity of the tank. It was also necessary to have a ‘concrete’ finish at ground level to reinstate this area of the garden to its original condition. The air blower for the Tricel Novo was installed within a remote underground housing with an independent RCD protected power supply being installed from the property to this housing.

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.

Sewage Treatment Plant Installation in Norfolk – National Trust

Sewage treatment plants offer Norfolk 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 Norfolk, Mantair is ideally placed to provide Norfolk homeowners with a sewage treatment plant to meet their site requirements, or provide the expertise required for assessing septic tank problems.

sewage treatment plant norfolk

Burnham Overy Tower Windmill in Norfolk was built in 1816 for Edmund Savory, a miller who was running a watermill on the River Burn known as the Lower Mill.  Savory worked this mill in Norfolk until his death on 9th February 1827, when it passed to his son John.  The mill was given to the National Trust in 1958 and has been converted to holiday accommodation.

The National Trust contacted Mantair with a view to installing a domestic sewage treatment plant to solve the septic tank problems at the property.  The project included the design and installation of an appropriate packaged sewage treatment plant with pumped outlet to facilitate the foul water drainage on site.  Prior to the design element of the project, Mantair carried out a full site investigation including a detailed survey of the existing drainage and underground services.

On sizing the new sewage treatment plant it was necessary to install an 18 population equivalent Tricel treatment plant to cope with the flow and strength of sewage the system would receive.

sewage treatment plant norfolk installseptic-tank-problems-norfolksewage-treatment-plants-norfolk

During the design stages of the project, Mantair liaised with the Environment Agency to determine the point of discharge for the overflow from the system.  Due to site levels it was necessary to have a pumped outlet on the Tricel sewage treatment system to enable the treated effluent to be discharged to the agreed outlet point.  With the sewage treatment plant having an integral pump Mantair installed a high level alarm and beacon with back-up battery to provide instant warning of power failure.

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 scope of the installation works included:
  • Exposing the existing foul drainage pipework and installation of new drainage to the Tricel sewage treatment plant;
  • Complete installation of the Tricel treatment plant in a suitably sized excavation and backfill;
  • Installing a MEDO air blower within an existing outbuilding and provision of an RCD protected power supply;
  • Installation of the air main from the MEDO air blower to the Tricel sewage treatment plant;
  • Installation of the pumping main from the Tricel system to the point of discharge, including for the installation of an inspection chamber.

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.

During the project Mantair engineers took all the necessary measures to ensure minimal disruption to the property and its surroundings.

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 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.

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.
