Our range of polyethylene pump chambers provides durable and customisable solutions for sewer, effluent, stormwater and trade waste applications. Manufactured from corrosion-resistant polyethylene, these tanks deliver exceptional strength, flexibility, and long-term performance for both underground and above-ground installations.
With a wide range of sizes and cover options, each polyethylene chamber can be tailored to suit residential, commercial, or industrial projects – from small sewer poly pits to large stormwater storage chambers.
The DrainAce Compact is commonly found in restaurants, basements of high-rise buildings, boardrooms, laboratories, doctor or dental surgeries, construction sites and portable buildings. Units are also available for greasy waste discharge from grease arrestors.
Our polyethylene tanks are used across a wide range of applications, including:
These systems combine strength, reliability, and ease of installation - making polyethylene tanks a proven choice for long-term water and wastewater management.
Each tank is manufactured from linear low-density polyethylene (LLDPE), a tough and lightweight material with high impact resistance and excellent chemical durability. All tanks are engineered using FEA modelling and ultrasonic wall testing, ensuring compliance with loading requirements.
Tanks are available in a wide range from 175 L to 10,500 L, with diameters and depths to suit site-specific requirements such as shallow rock installations or deep narrow sewage pump chambers with low inlet levels. Above-ground polyethylene holding tanks are also available for stormwater storage, pre-treated wastewater, or emergency containment.
All chambers are manufactured to strict ISO9001:2015 quality standards and certified to AS/NZS 1546.1, with Department of Health approvals on applicable models. By ensuring our pump stations comply with the relevant standards, we guarantee reliability and regulatory compliance. These designs also highlight the inherent benefits of polyethylene - corrosion resistance, low maintenance, and long service life.
A wide variety of cover options are available to suit both load requirements and access needs. These include:
Covers can be selected based on load class, access type and environmental sealing requirements. Some options require a concrete surround for full load-bearing performance.
When comparing polyethylene tanks with fibreglass reinforced plastic (FRP) chambers, polyethylene offers clear performance and lifecycle advantages.
Our DrainAce® Polyethylene combines structural flexibility with chemical stability, making it the more reliable, efficient, and cost-effective choice over FRP for long-term wastewater and stormwater containment.
