How to Remove Sewage Sludge from Your Septic Tank?

Overview

Every septic tank or sewage treatment plant requires regular emptying as part of their maintenance.

De-sludging is necessary at least once a year to prevent system failure as solids could rise to the height of the outlet pipe and then get carried along with the liquid into the percolation area. The trenches could then be blocked and cause flooding.

How often should sewage sludge be removed?

Depending on usage and the number of house occupants, de-sludging may be more frequent.

You will need to often monitor the level of the sludge. If you don’t your alarm might set off because your tank is too full with sludge.

How to remove sewage sludge?

This process is carried out with a vacuum tanker by a professional. This task cannot be completed by homeowners under any circumstances: 

  1. Remove the access cover
  2. Empty the sewage treatment plant or septic tank using a vacuum tanker. Care must be taken not to damage the unit with the hose of the vacuum tanker.
  3. Replace the de-sludging access cover securely.

Important notes:

  • Do not let this heavy equipment drive over the tank. Maintain a distance of at least four meters away from the covers of the tank.
  • The access cover should never be left off while the unit is unattended.
  • Never undertake de-sludging alone.
  • The property owner has a legal responsibility to ensure that all necessary precautions are taken to prevent pollution, a health hazard or nuisance.

Who can remove sewage sludge?

The de-sludging of the sewage treatment system is your responsibility as the homeowner. It is required when the sludge, produced from the first sewage treatment inside the tank, is occupying 50% of the volume of the primary chamber.

The emptying of your tank should be carried out by a licensed waste disposal company for health and safety reasons. Indeed, sewage can carry bacteria and gases harmful to human health. That’s why only qualified people should carry out this type of maintenance.

Moreover, suitable protection equipment including gloves, goggles, etc. should be worn at all times and removed after completion of work.

It is also essential to wash hands and face before eating, drinking, or smoking afterwards.

You can check out on the Environment Agency website the register of waste carriers, brokers, and dealers to find a competent company.

Regular maintenance checks

In general, to ensure the efficiency of your system, you should perform several regular checks on your septic tank or sewage treatment plant:

 

  •     Check the sludge level – visual inspection. If the tank is more than half full, it might be time to book a de-sludging service.
  •     Check outlet distribution box when available (the effluent should be free-flowing and clear).
  •     Check all vents (not blocked or covered with overgrown grass).
  •     Check air blower (when available); you should hear a gentle sound.
  •     Check for odours.
