The course provides a comprehensive overview of public water supply networks and their operation. It covers a wide range of topics which will enable staff to understand:

• What water supply networks comprise
• How they operate
• Typical water use patterns
• Basic network design (for developments), fire flows, metering
• An overview of watermain construction and asset management

• Outline the various components of water supply networks and how networks operate
• Explain hydraulic grade line (HGL), static and dynamic pressure (and how to calculate static pressure)
• Identify what is involved with operating water networks including issues relating to water quality
• Understand the overview of pump stations (pump curves, HGL, case study) and water meters (types, accuracy, design and installation, accuracy and testing)
• Learn the understanding system water use (with examples) and forecasting water demand
• Understand the overview of network modelling and demand management
• Learn firefighting flow requirements including basic information on fire sprinkler systems and water network design for developments
• Understand the overview of watermain construction (typical drawings, schedule, construction photos, pressure testing, chlorination, commissioning, and basic asset management considerations.
