Domestic Package Sewage Treatment Plants.

All sewage treatment plants are based on the same principle: to create the right environment for aerobic bacteria to be produced. The addition or presence of air creates microorganisms to break down the sewage, with various treatment and settlement zones. The effluent quality from most leading manufacturers is 95% or above clean water through the various stages of sewage treatment. The effluent from sewage treatment plant can discharge to watercourse if compliant to Environment Agency requirements or discharge can be made by soakaway if ground conditions are suitable.

Case Study

We were contacted through our website submission form to replace existing septic tank in the Norfolk area. The customer was keen to resolve there off mains drainage issues due to frequent emptying costs caused by soakaway failure. The property was located on poor ground conditions making a package sewage treatment plant our only option to overcome the problems previously experienced by existing septic tank. We selected Marsh Ensign best suited for high water table areas due to its low profile design reducing digging depth. The clean effluent produced was suitable to discharge to nearby ditch further to liaising with the Environment Agency on the customer’s behalf.

  • Prior to installation all underground services were located with cable avoidance tool, trail holes were dug in several locations to locate electric supply running across the farm yard.
  • Dig down by hand to intercept the incoming drain run, transfer old clay wear pipe to new modern PVC pipework, and redirect the drain run to new package sewage treatment plant.
  • Depth of sewage treatment plant excavation was determined by the drain run invert, excavation was sized to manufacturers specifications, and concrete back fill to surround tank.
  • Electrical supply was trenched from the farm to the sewage treatment plant control panel. The power supply runs the air blower for treatment and pumped outlet to elevate effluent to the ditch.
  • Sample point fitted before discharge to comply with the Environment Agency requirements, Head wall fitted on the bank of the ditch to stop erosion from discharge, re-established excavations to leave neat and tidy, with seeded finish.
