Sewer Rings to Detect Polluted Water

A new sensor to be installed in sewers will help unveil illegal pollutants infecting water systems and the culprit behind the pollution. This sensor rings, invented by engineers in Germany, are able to recognise what chemicals are hazardous in the system and can go a step further to identify who the polluter is or where the chemicals are coming from.

How?

When tainted water is sensed, the system notifies safety agencies which can then see where the water has been polluted and can ultimately help close in on the identity of the offender.

The design of the sewer system is comprised of 3 parts: 2 rings directly attached to each other that communicate back and forth and a 3rd ring placed lower down in the canal which is only activated when the first two rings sense a hazard. The 3rd ring has a chemical sensor and a sampling system to take direct samples of the possibly tainted water.

Next Steps

The system has proven to be successful in a number of small scale tests and is due to be tested large scale with partners in 5 European cities.
