Description
The AS 2416.1 "POLLUTED WATER" sign alerts the public to waterway contamination from algal blooms, stormwater overflow, sewage spills, or industrial discharge. Used by councils and environmental agencies during acute pollution events and at permanently impaired waterways where public access poses a health risk. Choose polypropylene (1.6 mm) for rapid temporary deployment on beach posts or creek access points — cable-tie holes enable quick installation and removal. Marine aluminium suits permanent ocean-outlet or tidal-zone installations where salt corrosion is a concern. Vinyl works for indoor pool facilities and council notice boards. Four sizes (225×300 to 600×900 mm) accommodate different visibility distances and fence types. Platinum Signs stocks all material grades and delivers Australia-wide. Councils and water authorities receive trade pricing and can arrange standing orders for seasonal or emergency response deployments.
Final sign type, wording, size, placement and material depend on the site risk, project specification and applicable jurisdiction. Confirm the requirement with the relevant WHS adviser or regulator.

Frequently asked
Which material for a one-off algal bloom event?
Polypropylene 1.6 mm with cable-tie holes is the standard choice — it's affordable, installs in minutes on existing posts, and you can remove it once water-quality testing clears the waterway.
What size should I choose?
Available sizes are 225 x 300mm (Small), 300 x 450mm (Medium), 450 x 600mm (Large), 600 x 900mm (Extra Large). Viewing-distance notes are a practical selection aid, not a substitute for checking the approach distance, lighting, mounting position, wording and site risk assessment.
Can I use this sign permanently?
Yes — marine aluminium is engineered for permanent tidal-zone and ocean-outlet installations. Polypropylene suits seasonal or temporary deployments but will degrade faster in direct sunlight over years.
Do councils get special pricing?
We offer volume discounts for local government and water-authority bulk orders. Set up a trade account and we can arrange standing orders for emergency-response stock.
Can lamination help with durability?
Lamination adds UV protection and scratch resistance, extending the sign's life in high-traffic areas or extended temporary deployments.
