19 Apr Multinational electric and gas utility taps 3P Utility Services for metro curb-valve install
To meet mandates from a U.S. metropolitan fire department and its city’s building code, a multinational electric and gas company called on 3P Utility Services to help the utility install shut-off devices outside buildings, so first responders can easily turn off gas service during emergencies. From September 2018 to July 2019, 3P Utility Services installed approximately 2,200 shut-off devices, or curb valves, across the city.
“To ensure safety and avoid power disruption, we dug everything on this project by hand or jackhammer,” said Shane Mullenix, a superintendent at 3P Utility Services. “These were low-pressure gas lines, either copper or steel, and our crews started by checking and turning off service inside each building or residence. Our crews would then dig at the curbside and put in a leak detector. If there were no leaks, we installed the curb valve, checked for leaks and relit the customer’s appliances or equipment.”
According to Mullenix, many of the gas service lines coming from the low-pressure main in the street were approximately 70 years old. If 3P Utility Services crews detected gas leaks at the service tee or elsewhere along the gas service line, the crews would dig out the service line and replace it with a new one while cutting in new curb valves along the way. 3P Utility Services also included operator qualification classes, when needed, for some of the union crew members from local halls who worked on the project.
