Septic Tank Tricel Vento



First of all, the tank is divided into two chambers, 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 in blow moulding technology. This market-leading product possesses high strength and durability characteristics, when combined with its lightweight this ensures ease of installation that makes 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 Septic Tank Works


Stage 1: First, the wastewater flows by gravity into Chamber 1 of the Tricel Vento, where the solids and heavier material settle to the base of the unit. A small amount of anaerobic breakdown occurs at this stage.

Stage 2: Then, the liquid and lighter waste material flow over the baffle into the second chamber. A layer of scum forms at the top of the liquid. A specially designed outlet filter is fitted to the unit to ensure that only the liquid flows into the percolation area. This outlet filter prevents the solids from passing into the percolation area which may block pipes.

Stage 3: Finally, the improvement of the wastewater occurs as it penetrates through a specially designed percolation area.

Discover the whole project from the very beginning.


Following the decision to extend Claran National School, the site engineer Patrick J Newell recommended an upgrade of the current system.

This was in order to identify a new suitable wastewater treatment solution and upgrade the existing septic tank installation in line with the Environmental Protection Agency (EPA) guidelines.
