When standard doesn’t fit...
In the world of industrial safety, there’s often no room for compromise. That was the case when we were approached by a client in Kwinana working on a project requiring a chemical storage solution. The catch? Their tank had to be under 1.6 metres tall, no wider than 1.85 metres, and hold at least 3,000 litres of foam concentrate.
At West Coast Poly, we know the limitations of off-the-shelf solution don’t always work on site. With no tank in our standard range that met both the volume and strict dimensional constraints, our fabrication team proposed a custom modification, by taking one of our 9,000 litre chemical tanks and carefully reducing the height to suit. The original apex roof was removed and replaced with a flat, heavy-duty HDPE roof, reinforced to maintain rigidity while maximising usable volume.
This approach gave the client a gross volume of approximately 4,000 litres within a footprint of 1.80 metres in diameter by 1.60 metres in height. Designed to accommodate a specific gravity of up to 1.5, the tank included multiple precision-cut nozzles in carefully mapped locations based on the client’s 3D model and functional requirements. These fittings enabled integration of a drop-pipe inlet to prevent aeration, a pressure-vacuum vent in lieu of a standard atmospheric vent to limit oxygen contact, and side-mounted nozzles for level indicators and switches to support accurate volume monitoring and fail-safe pump cut-off.
Alongside these technical requirements, we also provided an inspection hatch mounted on the roof, metal confined-space signage, and a fully certified hydrostatic test with an 8-hour hold. Our team worked closely with the client through every detail, from tank geometry and nozzle orientation to fabrication documentation, STEP files for model placement, and site-specific delivery considerations.
For us, this project exemplifies what’s possible when customisation meets collaboration. The finished product wasn’t just a tank, it was an engineered solution, tailored precisely to fit the footprint, the fluid, and the functional safety requirements of an essential industrial application.
From water tanks to chemical process tanks, we continue to support WA industry with certified, durable storage systems designed and built right here in Canning Vale.
