Cement and Masonry


Masonry activities create wastes that are among the many common stormwater pollutants that can degrade water quality. Cleaning masonry tools and equipment generate a variety of wastes. Excess cement and rinse water are a couple of examples. It is illegal to dispose of these wastes to the storm drain system! Cement dumped into the storm drain system can cause blockages which can result in flooding. Rinse water from cleaning tools and equipment is toxic to plants and aquatic life.

What can I do?

Use Best Management Practices (BMPs)!
BMPs are techniques or controls used to prevent or reduce the discharge of pollutants, such as cement rinse water, into the stormwater conveyance system also known as the storm drain system.

Tip: Use designated washout areas.
