MantairCase Study - Sewage Treatment Plant Installation in Surrey.

Location Small Business Park, Near Guildford, Surrey.

Mantair were approached by the owner of a small business park in Surrey regarding the problems being experienced with the foul drainage system serving the park.

After lengthy discussions with the client, Mantair engineers identified that the existing sewage treatment plant serving the park had failed and was causing pollution in a nearby watercourse. Mantair engineers recommend a site visit was conducted to inspect the existing treatment plant.

Survey & Design

On inspecting the existing sewage treatment system Mantair engineers were able to determine the existing system was beyond repair. It was decided to replace the existing sewage treatment plant with a suitably sized system, and locate the new system in a more discreet area of the park.

Taking into account all of the site requirements, Mantair 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.


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.

The scope of the installation works included:

  • Exposing the existing foul drainage pipe work and diverting to the location of the new 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 110mm diameter discharge drain to the boundary ditch;
  • De-commissioning and filling-in of the ageing sewage treatment plant;
  • Backfilling all excavations and leaving the area neat and tidy.

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

Mantair removed all machinery from site and left the garden area in a neat and tidy manner.

Mantair revisited this Surrey location a month after the completed installation to level the excavation area where the ground had sunk with topsoil.
