- Model HDPE - Precast Concrete Septic Tanks



Armtec’s precast concrete septic tanks are a key part of household and commercial septic systems. Septic systems treat sewage waste in an environmentally responsible way. Naturally occurring bacteria completely treats the waste and the water is returned to the ground via a weeping tile or chamber-based leaching bed.

Our tanks are available in a range of sizes to match the sewage load of the household, from 600 to 19,000 gallons. Accessories include lockable risers and covers, plastic inlet and outlet baffles, inlet and outlet polyseals, and lifting anchors.

Armtec is also a distributor of the FAST (fixed activated sewage treatment) System – a low-profile septic system that requires 1/3 less tile field than traditional septic systems. On a per litre basis, FAST offers one of the most cost-effective and reliable treatment processes available.
