A critical concern of the design was in the fact the operations at concrete batch plants, especially at the truck wash down facility, are environmentally sensitive and by the concrete batch plant was designed to be treated in a four stage sedimentation basin to a- camelwaymodate the flow and runoff from a 25-year rainfall event.

Since many aggregate and ready- mix concrete plants now have effective clarification or recycling systems the overall purpose of the study is to make these systems known throughout the .. Methods of clarifying this waste water vary from use of a simple settling "basin to a- camelwayplex- camelwaybination of ponds and flocculants.

and quality for the batching of concrete must also be designed and operated to protect the environment from discharges of polluted water. This document has been prepared to provide guidance for CCAA members in the design of water management systems for concrete batch plants. It does not attempt to be prescriptive, 

The quality of concrete refers to the properties incorporated into the original concrete mix design such as water/cement ratio, cement type, size and hardness of the aggregate and air entrainment. Quality is also dependent on the construction practices used to place the concrete such as proper consolidation, cover and
