This module introduces the infrastructure that delivers treated drinking water from treatment facilities to homes, businesses and other users. It explores how distribution networks, storage facilities and pumping stations work together to maintain sufficient flow, appropriate pressure and water quality.

Participants will learn how daily and seasonal demand patterns influence network operations, examine the causes and impacts of leakage, and discover how monitoring and proactive maintenance help reduce water losses. The module also introduces measures that strengthen supply resilience, including alternative supply routes, emergency storage, backup pumps and power, and effective incident response planning.
