# Chapter 3: Framework for Management of Drinking Water Quality: the twelve elements

This chapter details the 12 elements that make up the Framework for Management of Drinking Water Quality (the Framework). Each element includes an introduction and a list of the components that make up that element, which are then described in further detail. A ‘summary of actions’ box heads each component, providing an overview of the steps involved in implementation.

Some elements of the Framework are more complex than others, and therefore require further explanation. Appendix 1 (located at the end of the Guidelines) provides additional information and guidance for two elements ­– *Assessment of the drinking water supply system* (element 2) *and Preventive measures for drinking water quality management* (element 3).
