Concrete washouts are containment systems designed to capture and treat slurry and wastewater generated from cleaning concrete trucks, tools, and equipment on construction sites. These systems prevent high-pH water and cement-based solids from entering storm drains or natural waterways, helping sites stay compliant with environmental regulations. Washouts can be portable or stationary and are often lined or prefabricated for easy setup and removal. By isolating and filtering concrete waste at the source, they reduce pollution, protect water quality, and support sustainable jobsite practices.
