Water Tank Products Range

At West Coast Poly, we build water tanks for every part of Western Australia — from metro courtyards, to large blocks and wide open farmland. Proudly manufactured in Perth WA, our tanks are designed for local conditions, so whether you’re looking to store rainwater for your garden, secure a reliable water supply for livestock, or reduce your mains water use, our tanks are designed to do the job — and built to last.

For rural properties, farms, and larger blocks, our range of water tanks from 4,500L to 50,000L provide reliable water storage. Lightweight and easy to install, each tank is engineered for strength using a seamless, one-piece moulding process that’s perfectly suited to WA’s demanding climate. From collecting runoff off a shed roof to everyday farm use, they’re built for life on the land.

In suburban areas, where space is often a challenge, our slimline and compact tanks — ranging from 320L to 4,500L — are designed to fit neatly down the side of a house, under eaves, or into tight backyards.

For the next step in water efficiency, our automatic rainwater harvesting systems offer Perth households a seamless way to collect and reuse rainwater inside the home. These plug-and-play systems offer a sustainable, low-maintenance solution that helps reduce your reliance on scheme water.

Every tank we produce is manufactured right here in WA at our Canning Vale facility. Each tank is tested, certified, and built to our exacting quality standards — backed by ISO 9001 and WaterMark accreditation.

Whether it’s for the family home or the outback, water matters — and a tank from West Coast Poly is a simple, effective way to harvest rainwater and take control of your supply. With delivery available across Western Australia and expert support just a call away, getting started couldn’t be easier, get in touch with our friendly team to find the right tank for your property.
