Smart City Drainage Capacity Management

Resilient Drainage Asset Management Solution

Hundreds of municipalities, conservation authorities and water management professionals use Smart City Water's software solution to manage drainage assets, model and simulate sanitary and stormwater networks, and predict flooding before it happens.

What is a drainage capacity management system?

A collection of telemetered monitoring stations sending digital information to a self-correcting hydrologic/hydraulic modelling engine, resulting in near-real-time flow predictions for any gauged and non-gauged locations. The smart system inspects, monitors, predicts and verifies performance at all locations under multiple scenarios.

Introducing a customizable dashboard for drainage system monitoring and analysis.
