In most windy urban settings, yes—you should anchor them, but you probably don’t need a custom engineered system for every bin. A standard manufacturer-approved anchor kit, weighted base, or concrete pad is often enough, as long as it’s matched to the can size, the surface, and the local wind exposure.
The key is wind load. A large, empty bin can catch wind like a sail, and a full bin can become heavy enough to hurt someone or damage property if it tips. On exposed corners, plazas, waterfronts, bridges, and streets with strong gust channels, I’d definitely secure the can rather than rely on weight alone. For asphalt or pavers, use appropriate anchors and consider a reinforced base; for concrete, wedge anchors or cast-in anchors can work well. Coastal or hurricane-prone areas may call for more corrosion-resistant hardware and stricter anchoring.
So the practical answer is: high-wind urban areas usually need anchoring, but “special” anchoring depends on the site. Check local codes and wind-load requirements, ask the bin manufacturer for anchoring guidance, and make sure the installation is serviceable so crews can still empty and maintain the can safely.
