Porous concrete makes flooding almost impossible, does away with storm drains

Here’s an invention that’s desperately needed in the flood prone metro: Pervious concrete. It’s a type of concrete that’s extremely porous and doesn’t require sand, is able to allow water to seep straight through into the ground water stores below and does a good job standing in for regular concrete for most applications. Since the porous nature of the concrete allows water to go right through it, a lot of other flood management structures like retention ponds and swales are made obsolete, lowering the overall cost of road projects. We’ve linked a demonstration of the thing in action below, in which 1500 gallons of water is dumped on Pervious concrete in 5 min with the water going straight through, equivalent to 43 inches of rain event with no runoff.
