Water & wastewater range
Potable water tanks
FRP water storage tanks for drinking water, built with integral fibreglass ribs, premium resin without fillers and a design that is 100% watertight.
Stormwater tanks
Underground FRP tanks for stormwater storage, lightweight to ship and easy to install in remote locations and tight footprints.
Wastewater & effluent tanks
Underground FRP tanks for wastewater and effluent, corrosion resistant to the stored liquid and the surrounding soil, and designed to be 100% watertight.
Fibreglass pump stations
One-piece FRP pump stations built to each project's specification, WSAA appraised and quick to install on site.
Aquator® oil–water separators
The Aquator® dual-chamber oil–water separator removes light liquid pollutants from contaminated wastewater using coalescing media, with no power needed to operate.
Which tank or pump station do I need?
Start with what the tank holds. Every tank and station is designed to suit the site, so send us the volume, flow and ground conditions and we’ll size it.
| If you need | Choose | Why |
|---|---|---|
| Drinking water storage, above or below ground |  Potable water tank | Up to 150,000L, premium resin without fillers, and 100% watertight. |
| Stormwater detention or harvesting underground |  Stormwater tank | Up to 150,000L for some applications, light enough for remote sites and tight footprints. |
| Wastewater or effluent storage |  Wastewater & effluent tank | Resists corrosion from the effluent and the soil, with no lining or coating. |
| Sewage or wastewater pumping |  FRP pump station | One-piece and WSAA appraised, 1.5–3.75 m in diameter and 2–14 m deep, with a 30-year warranty. |
| Oil and fuel out of stormwater runoff |  Aquator® oil–water separator | Class 1 outlet quality at up to 60L/s, with no power needed and no bypass. |
Underground water tanks
An underground tank keeps water storage off the surface of a tight site. Our FRP water and stormwater tanks have integral fibreglass ribs, so they go in below the water table without a lining, coating or ongoing maintenance, and sizes run up to 150,000L for some applications. Because they are light, a large tank ships on one truck bed to remote sites.
