Engineered Poly Products

Simply The Best Approved Septic Tanks. Ever.

COERCO septic tanks are manufactured through one-piece moulding. This ensures that they are exceptionally strong, durable and reliable, with no joins or weak points in their construction.

Built from polyethylene, these septic tanks are lightweight, resilient, and super flexible for ease of transportation and many say they are the easiest septic tanks to install when compared to the more traditional options available such as concrete.

These are fast becoming the first choice all over Australia for septic tanks because of the unmatched value and benefits they bring to the consumer.
