A new type of concrete system can drain 1,056 gallons of water a minute , an innovation that could be integral after a storm since it can reduce the risk of flash flooding and other serious consequences.

The issue is that the majority of existing drainage systems are designed to remove rainwater as quickly as possible and funnel it into watercourses or drains. As a result, during heavy rainfall, public sewer systems quickly reach capacity and consequently overflow.To offset the flooding issue, the permeable concrete functions as a reservoir, and delays storm water from discharging into watercourses or drainages […]
