Washing out ready-mixed concrete trucks on-site

The Environment Agency publishes Pollution Prevention Guidelines, including PPG6 ‘Working at construction and demolition sites’, a guideline that is intended to assist with those in the construction and demolition industry.

This states that precautions must be taken to ensure the complete protection of watercourses and groundwater against pollution. Further, it states that ‘Suitable provision should be made for the washing out of concrete mixing plant or ready-mixed concrete lorries. Such washings must not be allowed to flow into any drain or watercourse.’ Ready-mixed concrete trucks should not be allowed to wash out anywhere other than the areas designated for the purpose. Purpose built wash-out skips are commercially available.

Sites are considered according to individual circumstances and early consultation with the local Environment Agency office is advised.

Alternatively, the Environmental Control Officer at the local council can be consulted.
