After severe 2010–2011 floods, national water agency PUB built an island-wide drainage-monitoring network: more than 1,000 water-level sensors in drains and canals plus over 500 CCTV cameras (48 of them public-viewable, refreshed every 5 minutes). A round-the-clock Joint Operations Centre fuses sensor, rain-gauge and radar data, while the public gets flash-flood warnings via SMS (at 50/75/90/100% canal depth), the @PUBFloodAlerts Telegram channel, the myENV and MyWaters apps, and Google Maps. PUB plans 650 more sensors by end-2028.
