Bio retention is the process in which contaminants and sedimentation are removed from stormwater runoff. This long-term civil engineering remediation project will stop rainwater from getting into sanitary sewers. Precast bio retention basins will capture and hold stormwater and allow runoff to slowly filtrate into bio/filtered swales strategically located throughout the city. Delta Precast provided design for up to 56 bio retention units, ranging in size from 20’ to 130’ long and weighing up to 20,000 pounds.
