Water infrastructure — it’s boring. Invisible. We only care about it when things go wrong, and things have been going wrong. Punishing storms have caused catastrophic flooding in New York, Texas, Louisiana and elsewhere. But water systems are expensive, time consuming and hard to fix. Technology may provide some relief. Marketplace’s Jed Kim talks to Paul Robinson, the executive director of RISE, a nonprofit accelerator in Norfolk, Virginia, that helps develop climate tech. Robinson says one of the companies they fund is StormSensor, which puts sensors in storm and sewer pipes.
