Biological Stability in Drinking Water Distribution Systems

PAOTM (Post Graduate Education in Engineering and Management) New Insight in Water Treatment and Distribution

Target Audience

People working in the water sector and involved with drinking water treatment and distribution. People with interest in the fields of drinking water microbiology, microbial ecology and health related drinking water ecology. The employees of drinking water companies, PhD’s, post docs, researchers and consultants who are involved in drinking water treatment and supply.


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

This course will cover the aspects of drinking water quality and safety, from treatment to distribution and till the water reaches customers’ taps. The course is especially designed based on the distribution systems, where water is being distributed without maintaining the residual disinfectant within distribution networks. The lecturers will cover the content from both theory and practice by presenting state-of-the-art technology that is being used for the treatment of drinking water and best practices from the field used to maintain drinking water distribution. The course is a mix of theory and practice as well as exercises based on real situations from Dutch drinking water distribution networks.

The course will be held in Amsterdam, The Netherlands and can also be followed online. IWA members will get a discount of 10% off the normal fee, and participants from low-income countries (please see country classification here) will get 40% reduced fee (limited offer for up to 2 seats). In addition, by attending this course, PhD students can gain 3 GS credits (3 graduate school credits = 24 hours of workload).

Learning Objectives

In this course, participants will:

  • Get an insight into the monitoring methods for biological stability.
  • Learn about the effects of water source and treatment on the quality of drinking water.
  • Gain an insight into the factors influencing the biological stability within distribution networks.
  • Learn about the microenvironment of distribution networks and premises plumbing.
