Biological stability in drinking water distribution systems

New insight in treatment and distribution

Biological stability of drinking water is important to provide water that is microbiologically safe and pleasant to drink to the consumers. This is particularly relevant in drinking water distribution systems where water is delivered without maintaining a disinfectant residual, like in the Netherlands.

In this course, we will discuss the different aspects involved in biological stability of drinking water, at source, treatment, and distribution levels. Methods applied to evaluate biological stability will be described and their application addressed with examples from practice.

Experts from both academia and from water utilities will describe latest knowledge on critical parameters impacting biological stability.

Biologically stable drinking water

In this course, participants will learn about the following topics:

  • What is biological stability of drinking water?
  • What are the basic elements controlling microbial growth in drinking water?
  • What are methods to assess and study biological stability?
  • What are the factors influencing biological stability at source and treatment levels?
  • What are the factors influencing biological stability at  distribution level?


Meant for

Drinking water professionals, including project managers, advisors, process technologists, researchers concerned with water quality issues.
