From CBS:

NEW CANAAN, Conn. (CBSNewYork) – A Connecticut town has installed a cutting edge swimmer protection system at one of its very popular swimming holes.

As WCBS 880 Connecticut Bureau Chief Fran Schneidau reported, officials in New Canaan became the first municipality to implement a high-tech second layer of protection for swimmers.

I went to the company website and I was impressed. See the video above. Here is a link to the Wahooo Sensor product site with some information on how it works:

The Wahooo Sensor is a highly sophisticated microcomputer that measures time of submersion down to 1/1000th of a second. The Sensor determines the critical moment in time when a submerged swimmer is at risk of drowning—before the event is allowed to escalate.

The system generates two types of alerts: First, when a swimmer is submerged for a preset period of time (considered by experts to be "precarious") a discreet Yellow Alert serves as initial notification of a potential event. If the swimmer remains submerged for an additional preset period of time (considered to be "at risk" by experts), a more urgent Red Alert is indicated. Each and every time, staff is aware of the situation. A situation that otherwise could have been missed with tragic results.

The Wahooo SMS accurately and reliably alerts your staff to the risk of a possible drowning rather than indicating a drowning already taking place. When seconds are the difference between life and death, this can mean everything in preventing an event from escalating into a tragedy.
