Everything that falls on Brockton in winter has to go somewhere eventually, and the tricky hour is dusk, when the day's melt runs across a driveway and then quietly turns to glass. Water Wizard LLC clears with that in mind — plowing and shoveling down to the surface, pushing banks to where they will drain away from the pavement instead of back across it. Walks, steps and the strip behind the car are opened by hand. A driveway cleared properly stays cleared through the freeze that follows. The name suits the work; in a Brockton winter, handling snow is mostly about handling water.
