The cover of a pumping station, septic tank, or distribution box plays a crucial role in the proper functioning of your septic system. This element serves several important functions:



Access: The cover allows access to the interior of the pumping station or septic tank for maintenance, cleaning, inspection, and repair operations. Without a cover, it would be difficult, if not impossible, to access the internal components of these installations.


Safety: The cover protects access to the interior of the pumping station or septic tank, essential for preventing accidents. By keeping it closed, it prevents people, pets, and objects from falling inside, which could cause injuries or damage.


Sealing: The cover must be designed to be watertight, preventing water from entering the pumping station or septic tank, and unpleasant odors from escaping. This helps maintain a clean and hygienic environment.


Protection against contaminants: The cover also protects the interior of the pumping station or septic tank from contamination by debris, insects, animals, and other external elements that could clog or damage internal components. Cover in the distribution box

Why check these elements?

 A damaged cover can lead to various risks and problems, including water infiltration. This can overload the treatment chain and affect the overall system’s durability. Unpleasant odors and even accidents and injuries can result. Keeping an eye out helps avoid these complications and ensures the system’s proper functioning.

L’entretien des couvercles des stations de pompage ou des fosses septiques est essentiel pour assurer leur bon fonctionnement, leur longévité et leur sécurité. DBO Expert relève les anomalies lors des inspections annuelles, cependant, il est possible que des événements surviennent entre les inspections. C’est pourquoi il est important de rester vigilant de temps en temps.


Voici quelques conseils pour entretenir les couvercles d’une installation septique:


  • Occasional cleaning: Occasionally clean the cover with clean water and a brush to remove dirt, debris, and residues. Ensure the cover is clean to avoid the accumulation of contaminants that could damage its surface. Visual inspection: Conduct occasional visual inspections to identify any signs of damage, cracks, or corrosion on the cover. If you notice problems, consider repairing or replacing the cover.

  • Sealing check: Ensure the cover is always sealed. If you notice leaks or water infiltrations, it may indicate a sealing problem. In this case, consider repairing or replacing the cover’s sealing.

  • Lubrication: If your cover uses hinges or opening mechanisms, lubricate them periodically to ensure smooth operation and prevent corrosion.
  • Safety: Ensure the cover is always securely fastened and secured. Poorly fastened covers can cause accidents. If necessary, tighten the bolts or fastening latches.
  • Obstruction prevention: Keep the area around the cover clean and clear to prevent debris, leaves, or other items from blocking access.
  • Protection against heavy loads: Avoid placing heavy objects on the cover, as this can damage it. Do not park vehicles or place heavy equipment on the covers.
  • Replacement if needed: If the cover is severely damaged, corroded, or cannot be satisfactorily repaired, consider replacing it to ensure the safety and performance of your septic system.
