Which components are typically part of a municipal water supply system?

• A. Reservoirs and Water Towers Only
• B. Source (surface water or groundwater), Intake, Treatment Plant, Distribution Network, Storage Tanks, Pumps, and Distribution Meters/Valves
• C. Rainwater Harvesting Canopy
• D. Household Water Heaters

Answer: (B)

A municipal water supply system is a complete flow from where water comes from to where it goes to consumers, with treatment and controls to ensure safe, pressurized delivery. It starts with the source, which can be surface water or groundwater, and an intake that extracts water from that source. The water then goes to a treatment plant where it is cleaned and disinfected to meet safety standards. After treatment, water moves through a distribution network of pipes, aided by storage tanks to balance supply and demand and maintain pressure. Pumps drive water through the system, especially to higher areas or during peak demand, and distribution meters and valves manage flow, control pressure, and allow isolation for maintenance. Other options don’t capture the full system: reservoirs and water towers are storage components but not the entire network; rainwater harvesting canopy is not part of a typical municipal system; household water heaters are end-use devices, not system components.
