Data Science for Water Professionals (The Course)
Data Science for Water Professionals
Learn how to solve water problems with the R language
The term 'digital water utility' has become a popular buzzword in the industry. A digital utility can only exist when the people that manage the water improve their skills. This workshop introduces participants to the principles of data science and analysing data using the R language for statistical computing.
Participants will learn about the principles of data science and the basics of using the R language. This course focuses on providing a broad introduction to creating value from data. The objective of this course is to inspire water professionals to apply data science principles in their analysis and use computer code to solve problems.
Principles of Water Utility Data Science
The first session introduces a framework for best practice in analysing data and sharing the results. This framework derives from the book Principles of Strategic Data Science. The case studies each implement aspects of this framework.
Introduction to the R Language
The second session introduces the basic principles of the R language and applies these principles to compute the flow in an open water supply channel. The remainder of the course follows two case studies.
Case Study 1: Water Quality Regulations
In this first case study, participants apply their skills to laboratory testing data from an imaginary drinking water network. The case study revolves around checking the data for compliance with water quality regulations. Participants will analyse and visualise the data and create an automated PowerPoint presentation based on the data.
Case Study 2: Understanding Customer Perception
The data for the second case study consists of the results of a survey of American consumers about their perception of tap water services. Participants use the Tidyverse to clean, transform and visualise this data. The case study ends with participants creating a MS Word report to communicate the results of analysis.

Dr Peter Prevos is a civil engineer and social scientist who also dabbles in theatrical magic. Peter has almost three decades of experience as a water engineer and manager, working in Europe, Africa, Asia and Australia. He has worked on marine engineering, drinking water an sewage treatment projects. Throughout his career analysing data has been a central theme.
He also a PhD in business and is the author of Customer Experience Management for Water Utilities (IWA Publishing) and Principles of Strategic Data Science (Packt Publishing). In his work, Peter combines the social sciences with engineering to create value for customers.
He is currently managing the data science function for a water utility in regional Australia. The objective of this strategy is to create value from data through useful, sound and aesthetic data science. His mission is to breed unicorn data scientists by motivating other water professionals to ditch their spreadsheets and learn how to write code.
