What Does NOT Get Marked?
Private underground facilities, such as private utility lines and private distribution networks, do not get marked by facility operators. When a property owner or tenant has any type of private underground facility, they are responsible to locate those facilities or hire someone to locate them.
Customer-owned lines usually include any that serve outbuildings, hot tubs, security lighting, pools, and natural gas grills. The free locating service available through Iowa One Call applies ONLY to public facility operators. The diagram below shows a variety of utilities, some owned by the utility and some by the homeowner. Those utilities marked by dotted lines are typically owned by the property owner. Those lines will NOT be marked by contacting Iowa One Call. Private locating services will mark these for a fee.
After calling Iowa One Call, wait 48 hours (excluding weekends and holidays) before you begin your excavation! Remember to check for facility operator responses.
