Poly Septic Systems Offer Unbeatable Benefits


Our range of septic tanks and drainage systems are manufactured and certified in accordance with all relevant Australian standards and meet with all Department of Health WA, NT and SA approvals.

Poly Septic Tank Certification

We use only the highest quality polyethylene in the manufacture of our tanks, meaning they are durable, UV stable, lightweight and easy to transport and install. COERCO poly septic tanks are fast becoming the product of choice over concrete designs thanks to these unique properties.

From small, space-saving septic tanks through to industrial size large capacity systems, all our tanks come as a complete kit including a lid and inlet and outlet fittings.

The Highest Rated Poly Septic Tanks Manufacturer... By Customer Reviews!

" We have been very happy with the polyethylene septic tanks provided by Coerco, and we now use these as standard on all our new homes. Previously we used concrete tanks which were much heavier and needed machinery to lift them. We generally needed two concrete tanks compared to the one poly tank with a baffle which we now use as standard. This means we can install them faster, with less work, and less digging. We find the sales staff at Coerco to be very helpful, knowledgeable, quick to act, and professional in every respect. I would certainly recommend Coerco as a company. "

Craig Bassett - Elders Ltd, Geraldton, WA

" Fantastic Experience. The service was 10 out of 10, and the process was seamless from quote through to delivery. Was even more impressed after getting an after sales follow up call to make sure I was happy. "

Frank The Sheepdog , Katanning, WA

" Extra special thanks to the team at “Coerco”. I bought a full septic system and leach drains from them for my 40 acre property in Gingin. I can’t speak any higher of them from the people in the office to the delivery. Products are very very good and the people even better. I would highly recommended these guys to anyone chasing the products they stock! You won’t be disappointed. "
