Module 1: Drinking Water Hygiene and Public Health
Safe drinking water is essential for protecting public health. This module introduces the basic principles of drinking water hygiene, explains how contamination can occur, and presents the most important microbiological risks in water supply systems. Participants will learn how hygiene barriers, monitoring, and good operational practices work together to ensure safe drinking water from the source to the consumer.
This module introduced the main sources of drinking water used around the world, including groundwater, spring water, surface water, and seawater. Participants learned the advantages, limitations, and assessment methods for each source, as well as the key factors influencing source selection. Understanding water sources is the first step in planning a safe, reliable, and sustainable drinking water supply system.
After treatment, drinking water must be transported safely to consumers. A network of pipes, pumps, and storage facilities ensures a reliable water supply and adequate pressure. Regular monitoring and maintenance help protect water quality and ensure safe delivery from the treatment plant to the tap.
Drinking water storage is essential for ensuring a continuous and reliable water supply. Storage tanks and reservoirs help balance demand fluctuations, maintain system pressure, and provide emergency reserves. Proper design, operation, and maintenance are important to preserve water quality and prevent contamination.
Drinking water treatment removes impurities, harmful microorganisms, and unwanted substances from raw water. Various treatment processes ensure that the water is safe, clean, and meets quality standards. Effective treatment protects public health and provides reliable access to safe drinking water.
Module 6: Operating a Drinking Water Supply System
Operating a drinking water supply system involves the continuous control of treatment, storage, and distribution processes. Operators ensure stable water quality, adequate pressure, and reliable supply to consumers. Regular monitoring, maintenance, and rapid response to issues are essential to keep the system safe and efficient.
Module 7: Case Study – Building a Complete Drinking Water Supply System from Source to Tap
This module presents a real-world case study of designing a full drinking water supply system, from the water source to the consumer’s tap. It integrates abstraction, treatment, storage, and distribution into one coherent system. The focus is on system planning, coordination of components, and ensuring water quality and reliability. The case study highlights practical decision-making and key engineering considerations in real projects.
