4 Figures and facts about water 900 million people lack access to drinking water 90% of all diarrhoeal diseases could be avoided by proper water purification According to a UN Resolution of 2010, every person has a right to clean water By % of the world s population will live in regions with a lack of drinking water Water and wastewater plants are high energy consumers and responsible for up to 30% of municipal power consumption 80% of communal wastewater enters rivers, lakes and seas untreated 4

Demand for smart training solutions in the water and sanitation sector Nowadays training is not sufficient to cover the huge demand for skilled staff in a world of technological change.

5 Demand for smart training solutions in the water and sanitation sector Nowadays training is not sufficient to cover the huge demand for skilled staff in a world of technological change. The trainings available are usually too theoretical. Holistic and practice-oriented training solutions are needed to train staff efficiently. Analytical and problem-solving skills are most important to reduce waste and increase efficiency of a plant. Understanding the steps before and after a specific process helps to think ahead and reduce down times. Automation does not mean replacement of human resources, it helps to standardize key processes and produce clean safe water. 5
