Septic Tank Replacement

If you live in a rural area of the UK, your home will most likely be connected to a private drainage system, with the most common system being a septic tank.  In recent years we’ve seen an increase in septic tank replacements due to more stringent regulations surrounding the use of septic tanks.

It is widely known that many septic tanks discharge directly into ditches and streams throughout the UK.  Such discharges have been an offence since 1991 when the Water Resources Act came into force, including discharges that predate the enforcement date. A discharge of this type from a septic tank renders the homeowner liable to prosecution by the Statutory Authorities.

septic-tank-problemsseptic-tank-replacementseptic-tank-replacement

With the Environmental Agency and Local Authorities becoming more stringent on the use of septic tanks, it has been necessary for us to carry-out septic tank replacements using modern sewage treatment plants. Sewage treatment plants are specifically designed to ‘treat’ the receiving sewage to the extent that the final treated effluent is acceptable for discharge to ditches and streams.

Septic Tank Replacement – Case Study

We were contacted by the owners of this property in Essex after they had been informed their septic tank was pumping into a nearby ditch and causing pollution.  The homeowners had been advised that they would need to investigate the options regarding a septic tank replacement and employ the services of an ‘off mains’ drainage specialist.

After conducting a site inspection, Mantair engineers recommended replacing the septic tank with a Marsh ENsign sewage treatment plant, which would produce a ‘treated’ effluent suitable for discharge to the nearby ditch.

Based on the property having four bedrooms and in accordance with the British Water Flows and Loads Code of Practice – 4, a six-person Marsh system was recommended for installation.

septic-tank-replacementmarsh-sewage-treatment-plant

The Marsh ENsign sewage treatment plant is a ‘single tank’ system using a three stage treatment process. Central to the operation of the Marsh system is the aeration chamber.  Within the aeration chamber aerobic micro-organisms develop through the use of fine bubble aeration and floating plastic media.  This aeration process provides an extremely robust means of treating sewage, and provides an ideal solution for septic tank replacements.

As part of the project Mantair engineers liaised with the local Building Control Department to obtain the relevant approvals for the installation.

Prior to any ancillary works commencing, Mantair engineers scanned the proposed location for the Marsh system and areas where excavations were taking place to ensure that no underground services were present.

The scope of the installation works included:

  • Exposing the existing foul drainage pipe work and diverting to the location of the Marsh ENsign sewage treatment plant;
  • Installation of the Marsh system in a suitably sized excavation, including for a concrete base and back-fill;
  • Locating the air blower within a remote blower housing;
  • Provision of an RCD protected power supply to the blower housing;
  • Installation of the air main from the air blower to the Marsh system;
  • Connection of the outlet from the Marsh system onto the existing outlet drainage;
  • Emptying and filling-in of the existing septic tank.

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

All machinery was removed from site with the garden being left in a neat and tidy manner.

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.

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.

As leading independent installers and service providers for sewage treatment plants in Essex, Mantair is ideally placed to provide Essex homeowners with a sewage treatment plant to meet their site requirements, or provide the expertise required for assessing septic tank problems.

sewage-treatment-plants-essex

We were contacted by the owners of this property on the outskirts of Chelmsford in Essex with a view to replacing their failed cesspit system with a Klargester sewage treatment plant.

After conducting a detailed survey at this Essex location, Mantair engineers recommended the installation of a ‘below-ground’ Klargester Bioficient sewage treatment plant.  The Bioficient is the latest treatment plant produced from Klargester and provides a highly economical solution for sewage treatment in rural locations.

Using the British Water Flows and Loads Code of Practice – 4, Mantair engineers recommended the installation of a Ten-Person Klargester Bioficient system.  It was also a requirement to install a pumping station as the treated effluent needed to be pumped to a receiving watercourse.

Sewage Treatment Plant Installation in Essex

Sewage treatment plants in Essex are becoming increasingly more popular as they provide homeowners with a modern alternative to septic tank systems for areas without access to mains drainage. As leading independent installers and service providers for Essex sewage treatment plants, Mantair is ideally placed to provide Essex homeowners with a sewage treatment plant to meet their site requirements, or provide the expertise required for assessing septic tank problems.

Throughout rural areas of Essex, many properties, both domestic and commercial are not serviced by mains drainage for the disposal of waste water.  As leading independent installers of sewage treatment plants and septic tanks we provide Essex homeowners with a sewage treatment system to meet their budget and site requirements.

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.

Septic Tank Installation in Essex

We were approached by a homeowner looking for advice regarding a new septic tank installation in Essex. For septic tank installations Mantair provides a complete design, installation and commissioning service throughout Essex and surrounding County’s.

Case Study – Southend on Sea, Essex.

septic-tanks-essexseptic-tank-essexmantair

The client approached Mantair to discuss the options for replacing a failed septic tank which was serving multiple properties.  It was the clients wishes to have their own independent septic tank.

Site Investigations

Mantair engineers attended site to conduct a detailed survey of the existing drainage arrangements and carry out percolation tests to determine if the sub-strata was suitable for a septic tank soakaway system.

The results of the site survey showed that a septic tank installation would provide an effective means of waste water disposal, and provided the information required to determine the size of soakaway necessary.

Septic Tank Specification

Mantair engineers recommended the installation of a 2800 litre Klargester Alpha septic tank. The Klargester septic tank is made from composite GRP and is performance tested to EN-12566-1 requirements.

Septic Tank Operation

Sewage enters the septic tank into a settlement chamber, allowing solid waste (sludge) to sink and liquid to rise to the surface. This surface liquid makes contact with oxygen and the organic matter starts to breakdown biologically.

This liquid still contains sewage but in small enough particles to be carried through the discharge outlet and into the receiving soakaway.

Septic Tank Installation

Scope of the works included:

  • Exposing the existing foul drainage pipe work and installation of new drainage to the location of the new septic tank system;
  • Excavation of suitably sized hole in preparation for the installation of the septic tank;
  • Installation of the septic tank, including for a concrete surround;
  • Installing a new discharge drain from the septic tank to the existing soakaway system;
  • Removal from site of all surplus excavated areas;
  • Backfilling all excavations and leaving the area neat and tidy.

On completion of the ancillary works Mantair engineers commissioned the septic tank system and removed all machinery from site, leaving the garden in a neat and tidy manner.

Stringent regulations govern the installation of septic tanks and there are several reasons why a septic tank may not be allowed for installation. Should a septic tank installation not be suitable for your property then a Mantair engineer would guide you through the alternative “off mains” drainage solutions available.

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.

Septic tank conversion system installation in Essex.

mantair-installation-essexmantair-conversion-unit

Mantair was contacted by the owner of a property regarding the problems they were experiencing with their septic tank system.  The property is located on the outskirts of Brentwood in Essex.

On inspection of the drainage arrangements it was found that the property drained to a septic tank located in the rear garden of the property.  On internal inspection of the septic tank it was evident that a submersible pump had been installed within the tank with the sewage effluent being pumped directly to a boundary ditch.  It transpired that the previous owners of the property had installed the pump due to the septic tank soakaway failing.

On further inspection it was found that the existing septic tank was in good structural condition but there was insufficient land available for the construction of a new soakaway.   It was therefore necessary for a sewage treatment system to be installed which would produce a treated effluent suitable for discharge to the boundary ditch.

With the existing septic tank being in good structural condition and sufficient capacity Mantair 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.

To minimise the disturbance to the garden the existing pumping main was reused with a new pumping station being installed and connected at the ‘head’ of the pumping main.  The air blower for the Mantair septic tank conversion unit was positioned within a Beehive blower housing – a purpose built housing designed to blend into the garden setting.

beehive-blower-housingfinished-mantair-installation

Prior to any works commencing Mantair obtain a Permit from the Environment Agency for the discharge to the boundary ditch.

As with the majority of Mantair septic tank conversion system installations, the disturbance to the garden was minimal with substantial cost savings when compared to the installation of a packaged sewage treatment plant.

Mantair provides a comprehensive septic tank and sewage treatment plant service throughout the majority of the UK. 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 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.
