Digital Water: The importance of knowing what we do not know

Uncertainty in planning, designing and modelling of urban water infrastructure.

Uncertainty is an often unnoticed aspect of everyday life. The progressing digitalisation of the water industry brings more and more data and models into the heart of decision processes.

While abundance of data and availability of data analytics tools hold a lot of promise, a wide range of challenges are also associated with different types of uncertainty in data.

This whitepaper aims to raise awareness of the many sources of uncertainty in digital decision making and describes how digital water approaches and tools can help us to stay in control and make decisions with (at least some) confidence.
