Tricel Vento Septic tank


The Tricel Vento septic tank is an ideal solution for wastewater treatment when used in conjunction with the appropriate disposal system, it’s one of the septic tank options.

The tank is sized sufficiently to hold wastewater for an adequate amount of time for the solids to drop to the bottom to form a sludge and the lighter material to rise to the top of the liquid to form a scum.

As a result, the remaining liquid effluent is passed through the outlet pipe into the disposal system for final treatment. In addition, Tricel Vento septic tanks are manufactured from high-density polyethene using the latest blow moulding technology. This market-leading product possesses high strength and durability characteristics; when combined with its lightweight, this ensures ease of installation, making it ideally suitable for all septic tank applications.

In conclusion, the Tricel Vento septic tank is designed in compliance with EN12566-1 standards.

How a Tricel Vento Septic Tank Works ?

Stage 1:

Wastewater flows by gravity into the tank and is diverted downwards with a T piece where the solids and heavier material settle to the unit’s base. A small amount of anaerobic breakdown occurs at this stage.


Stage 2:

The lighter solids float to the top and form a scum, and an outlet pipe fitted to the unit ensures that only the liquid element flows into the percolation area. This specifically designed dip pipe prevents the scum from passing into the percolation area, which may result in blocked pipes.


Stage 3:

The effluent exits the septic tank for its final improvement as it penetrates through the specially designed percolation area.
