Pressure Zone
A Pressure Zone is a specific area in a water distribution system where water pressure is maintained at similar levels. Think of it like different "floors" in a building's water system - each floor needs different pressure to get water flowing properly. Water utilities divide cities into these zones because houses at different heights need different water pressures to get good water flow. People working with pressure zones help make sure everyone gets water at the right pressure - not too weak to reach upper floors, and not so strong it damages pipes.

Example Interview Questions
Senior Level Questions
Q: How would you approach redesigning pressure zones for a growing city?
Expected Answer: A senior engineer should discuss analyzing population growth patterns, evaluating current system capacity, considering elevation changes, and planning for future expansion while maintaining service to existing customers.
Q: What factors do you consider when optimizing pressure zone boundaries?
Expected Answer: Should explain considering elevation changes, population density, infrastructure age, energy efficiency, and operational costs while ensuring adequate pressure for fire protection and daily usage.
Mid Level Questions
Q: How do you maintain proper pressure levels within a pressure zone?
Expected Answer: Should discuss using pressure reducing valves, booster pumps, storage tanks, and monitoring systems to keep water pressure within safe and effective ranges.
Q: What are common pressure zone problems and how do you solve them?
Expected Answer: Should describe issues like low pressure complaints, pressure fluctuations, and equipment failures, along with troubleshooting steps and solutions.
Junior Level Questions
Q: What is the typical pressure range that should be maintained in a pressure zone?
Expected Answer: Should know standard residential pressure ranges (typically 40-80 psi) and explain why these ranges are important for customer service and system safety.
Q: What basic equipment is used to control pressure zones?
Expected Answer: Should be able to identify and explain basic components like pressure reducing valves, pumps, storage tanks, and pressure gauges.
