Plastic Three-Chamber Septic Tanks

Plastic three-chamber septic tanks represent a proven solution for the pre-treatment of wastewater for households, cabins, and properties without a connection to public sewerage. They serve as the first stage of treatment prior to a constructed wetland, soakaway/infiltration system, or as a holding tank.

In our range, you will find certified plastic septic tanks made of durable polypropylene (PP) with a long service life, available in both concrete-encased and self-supporting designs. The three-chamber construction provides mechanical settling of sludge, anaerobic decomposition of organic matter, and final calming of the water before the next treatment stage.
