Before the septic tank installation

You need to have all the information about your soil composition and the distances to respect and all the local requirements.

Concerning the septic tank, you should check for any damages and notify the installers if you think the tank can’t be installed (once installed the claims for damage won’t be accepted by the manufacturer).

During the installation

All installations need to “fit for purpose” to conform to the site conditions.

This is the obligation of the installer to follow the manufacturer’s guidelines. The step below may vary according to the specificities of the site and if it’s dry or wet.

See below an example of the Tricel Vento septic tank

  1. Remove any soft spots or large stones and boulders.
  2. The base of the hole is made of a 200mm layer of gravel.
  3. Make sure that the base is level.
  4. Lift the tank hole and place on the prepared plinth.
  5. The plant must sit dead level on the plinth.
  6. Join and seal the pipework to the tank.
  7. Mount and seal risers (if needed).
  8. Backfill following recommendations of the manufacturer.


After the installation

As a homeowner, it is your responsibility to maintain your tank.

Doing it carefully will avoid pollution of soils & rivers. Your septic tank should be inspected every 1 to 3 years. The inspection is a necessary procedure to check if the product is still operating properly.

Furthermore, you will need to empty the septic tank (desludging). The emptying process (the tanks and the mud management) needs to be handled by an accredited company.

Septic tank options for homeowners and small businesses include the Tricel septic tank system, which is manufactured to the highest international standard.

It is suitable for sewage treatment where sufficient land is available for an adequate drainage field and you have received approval from the planning authority. You may install a septic tank where soil conditions are suitable for the treatment of wastewater by meeting the standards set by the Environmental Protection Agency.

The price will vary based on the nature of the project, the location and the requirements. Let us know about your projects and options and we will get in touch with you.

Tricel septic tank and sewage treatment systems provide a comprehensive installation guide with each plant supplied. You should ensure that you are confident that you can meet the requirements outlined in the guide before you attempt installation. Advice on specific site conditions etc. should be sought from your on-site engineer.

This may be determined by digging a trial hole and leaving it open for 48 hours during the site assessment. Water level is measured from ground level.

Depending on your region you may be able to discharge directly into a watercourse or to a percolation area. Please consult your local council for more information on which option is suitable for you.
