human-771601_1920Water covers 71% of the Earth’s surface and is vital for all known forms of life.
The holistic consideration of water as an important means of nourishment as well as the general protection of lakes and rivers are a central basis for the growth and further development of human civilization. At the same time, the civilization itself, with its steady growth, is a menace to the purity of water resources used for drinking water supply and its distribution network. They are highly sensible to any kinds of contaminations.
The provision of clean and safe drinking-water is an essential task for water supply companies all over the world.
To deal with this scenario, highly sensible sensors monitor relevant water- and environmental data at several measuring points, on a regular basis. The monitored data can be analyzed to discover any kinds of anomalies.
This allows for early recognitions of undesirable changes in the drinking water quality and enables the water supply companies to counteract in time.
This year’s industrial partner is Thüringer Fernwasserversorgung (TFW), which provides the dataset used in this challenge. Goal of the GECCO 2017 Industrial Challenge is to develop an event detector to accurately predict any kinds of changes in a time series of drinking water composition data.

Highlights of the GECCO 2017 Industrial Challenge will include:

  • Interesting Problem Domain: Event detection based on drinking water data offers a challenging test case for modern time series prediction methods.
  • Real-world Data: Real drinking-water time series are provided for training, testing, and assessing event detection methods.
  • Direct Link to Industry: The Thüringer Fernwasserversorgung will evaluate the winning submissions for an implementation in real-world applications. Moreover, a direct contact with the winning participants, who will keep all rights to their detection system, is highly appreciated by Thüringer Fernwasserversorgung.

About the Thüringer Wasserversorgung
