Pathogens and Pathways, and Small Drinking-water Supplies provides information about the supply of safe drinking-water to small water supplies serving fewer than 5000 people. Communities need to make sure their water is safe to drink and that there are no micro­-organisms or other unwelcome contaminants present that could make people sick.

This document covers:

  • types of micro-organism (bacteria, viruses, protozoa, cyanobacteria, helminths)
  • pathogens and how they can affect people
  • ways pathogens can get into water (eg, damaged storage tanks or equipment failure)
  • measuring contamination.

This booklet is part of a suite of resources that have been produced for use by the Technical Assistance Programme Facilitators (TAP Facilitators) to deliver their TAP workshop activities to small drinking water supplies. The booklets are supplemented by reference notes, and powerpoint presentations to be used by the TAP Facilitators as they work collaboratively with drinking water supplies participating in the Drinking Water Assistance Programme.
