Materials and excess concrete or mortar can be blown or washed into the storm drains that flow to the ocean. Unlike water in sanitary sewers (from sinks and toilets), water in storm drains is not treated before entering our waterways. You would never throw building materials into the ocean, so don’t let them enter the storm drains. Follow the link to the right for a downloadable PDF brochure with tips for properly cleaning up and disposal of concrete and mortar.
Tips for Using Concrete and Mortar
Before starting the project, plan to schedule it during dry weather and minimize waste by ordering only the amount of materials needed to complete the job.
During the project, make sure to break up pavement and pick up all chunks and pieces and recycle them at a local construction and demolition recycling company.
While cleaning up, never hose concrete or mortar materials from exposed aggregate concrete, asphalt or similar treatments into a street, gutter, parking lot, or storm drain.
