Rain gardens, porous pavement & more can improve the quality of storm water entering the reservoirs that supply our drinking water.

Simple Steps for Concrete Disposal

Concrete CleanUpNever dispose of concrete washout or cutting slurry into the street, storm drains, drainage ditches or streams; it is against the law.

Train all staff on the importance and procedures for proper waste disposal.

Use as little water as possible to wash the chute, finishing tools, wheelbarrows, and other equipment; collect water and slurry for proper disposal.

Capture washout in a designated, well-marked washout area, bucket or other container.

Provide a marked washout area at the construction site for the concrete mixer.

Use sandbags, tarpaulins or diversion booms to direct wastewater to an appropriate washout area and prevent it from entering gutters and storm sewers.

Divert wastewater into a grassed area where it can soak in. Do not exceed the ground’s soakage capacity.

Collect wastewater in a washout area or with a wet vacuum so it can be pumped into a tank for re-use or hauled to an approved disposal facility.

Allow water to evaporate from washout and dispose of solids in the garbage.

Secure bags of cement after they are open. Keep them out of the wind which can carry fine material to storm drains.
