On-Site Stormwater Detention (OSD) Plate – Silver & Black
An on-site stormwater detention tank works only if nobody fills it in, builds over it or blocks the orifice, and the owners twenty years from now will not have read the DA. The OSD plate is how the system stays known.
A statutory notice plate printed in black on a brushed silver metallic background, carrying the on-site stormwater detention wording your council specifies – typically a statement that the property contains an OSD system that must not be altered, filled or removed, along with the council name and development consent number. Enter the wording and consent details at checkout and they are printed exactly as supplied. Councils across Sydney and NSW require this plate as a condition of consent for OSD systems; there is no Australian Standard governing the sign itself, so confirm the exact text and the required plate size with your council’s OSD policy or your hydraulic engineer before ordering. Aluminium gives the durable metallic plate most councils expect.
Proudly Australian-made and finished with a protective matt laminate for glare-free readability and long outdoor life. Choose your size, material and finishing at checkout; both compliant and decorative material and size options are available. The sign is supplied on its own, with no screws, zip ties or fixings included.
Mount it on the tank lid, the wall of the pit or a nearby permanent structure at a height that can be read without entering the system, as the council policy directs. Pairs well with our Custom Statutory Sign – Silver & Black and Rainwater Sign – Silver & Black. Made to order and dispatched within a 2–3 day turnaround.
