In general, which type of distribution system piping tends to have exposed piping?

• A. Pump station piping
• B. Distribution mains
• C. Household service lines
• D. Transmission lines

Answer: (A)

Pumping facilities are the part of a distribution system where you expect to see piping out in the open. The yard around a pump station houses the pumps, valves, discharge and suction lines, and associated equipment, so these pipes are laid out for easy access, maintenance, venting, drainage, and operation. Keeping this piping exposed allows technicians to inspect and service components quickly and reduces the need to excavate for routine work.

In contrast, distribution mains, household service lines, and transmission lines are normally buried underground to protect them from weather, damage, and tampering, and to minimize surface disruption. That’s why pump station piping is the one that tends to be exposed.
