Septic Tanks 


High strength and durability characteristics make up the Vento septic tank.

This market-leading product has a super low profile giving the added benefit for installations as it requires a smaller excavation.

This, combined with its lightweight feature, ensures ease of installation which makes it the ideal choice for all septic tank applications.

The Tricel Vento positions itself as a reliable wastewater treatment solution as an effective treatment alternative to sewage treatment plants.

How does a septic tank work?


  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 base of the unit. A small amount of anaerobic breakdown occurs at this 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 specially designed dip pipe prevents the scum from passing into the percolation area which may result in blocked pipes
  3. The effluent exits the septic tank for its final improvement as it penetrates through the specially designed percolation area.
