Biological maintenance of your sewage treatment plant

Annual maintenance schedule, natural bacteria and expert tips.

Why regular maintenance of your sewage treatment plant is essential

A well-maintained household sewage treatment plant or septic tank runs silently for years without issues. Neglected, it develops odours, blocks up and can lead to costly repairs. Regular biological maintenance — adding beneficial bacteria — is the most effective and cheapest action you can take. Natural bacterial strains continuously break down suspended solids, keep the bacterial balance stable, and prevent the formation of hydrogen sulphide (H₂S) which causes odour.

Well-maintained system

  • No odour problems
  • Optimal biological breakdown
  • Fewer emergency pump-outs
  • Extended lifespan of the installation
  • Compliance with environmental regulations

Neglected system

  • Chronic odour problems
  • Sludge build-up and blockages
  • Frequent, costly breakdowns
  • Risk of soil and groundwater contamination
  • Regulatory notices and fines
