Description
Efficient water distribution systems are vital for urban and rural communities, ensuring access to safe, reliable water for daily use and emergency needs. Understanding the core principles of hydraulics, pipeline mechanics, and network analysis provides the foundation for designing systems that meet regulatory standards and performance requirements. This course delves into these principles, offering insights into the operation of pumps, valves, and other essential system components while introducing tools like the Moody Diagram and Bernoulli's equation to enhance your analysis.

Participants will gain practical knowledge of designing water distribution networks using industry-standard approaches. From understanding peak demand and fire flow requirements to analyzing pipe flows and water quality, you’ll learn to predict performance and address real-world challenges. EPANET2, a widely recognized hydraulic modelling software, will be a key focus, allowing you to apply theoretical concepts to practical scenarios.

By the end of this course, you’ll be equipped to design, analyze, and optimize water distribution systems. Whether modelling a new system or troubleshooting an existing one, the skills you acquire will prepare you to address the complex demands of water distribution with confidence and precision.
