Stormwater is surface rainwater, melted snow or water that runs off our roofs, driveways and roads rather than soaking into the ground. Stormwater management includes managing the quantity and quality of the water, and providing safer flow rates and areas.

We continually assess and investigate the municipal watershed and stormwater drainage systems in Surrey's Drainage Study Areas to identify any needed upgrades and to determine ways to mitigate or prevent future problems. We then compile the results of these assessments into various drainage plans and reports.
