Premium Septic Tank Systems | Waste Management

Overview

Reliable, Low-Maintenance Wastewater Management

BIOSeptic’s concrete septic tanks provide a safe, natural and cost-effective way to manage household and commercial wastewater on-site. Designed for Australian conditions, our tanks separate and treat wastewater using a simple, proven process that requires no power, minimal maintenance and long-term reliability.

How a Septic Tank Works

A standard BIOSeptic septic tank uses a natural settling and digestion process to treat wastewater from the kitchen, bathroom and laundry.

Inside the tank:

Solids settle to the base
Oils and grease rise to form a scum layer
Anaerobic bacteria break down organic waste over time
Clarified liquid flows into a second chamber for final settlement
Treated wastewater then passes to an evapo-transpiration field, where it safely evaporates

This simple, passive system has been trusted for decades for rural, residential and small commercial wastewater management.
