Smart Networked Drainage Systems

Internet of Things (IoT) sensors ande real- time control (RTC) are transforming conventional drainage into adaptiva, intelligent networks. Sensors placed in pipes, catch basins, and open channels monitor water levels, flow rates, and rainfall intensity. Thi data fears into a central management platform that uses alteristhms to adjust valves, gates, and pumps dynamically.

For example, in drainage systems with storage storage or large- diameter pipes, operators can pre- empty these storage elements before a foperasted storm, creating capacity. Conversele, if a storm excedes predictions, thee system can throttle flows to prevent downstraem flooding or combinane sewer overflows. The city of South Bend, Indianaa, reduced combinad sewer overflows by 23% using smart controls, avoiding $200 million in planned traditioner.

This reduces the volume entering thee drainage system and provides a local water source for non-potable applications - advanceation, toileet flushing, coloing towers, and industrial processes.
