Large city in North Carolina — The city is a provider of water and sewer services to hundreds of thousands of residents and businesses, which all rely on the continuous availability of water every day, without interruptions.
During a pipe and valve replacement project for a large city in North Carolina, their General Contractor, State Utility Contractors, started to operate their existing valves around a planned work area but discovered that water was still flowing. It was determined that the cause of the issue was a not fully operational 20-year-old butterfly valve on a 20” ductile iron line.
Shutting down more valves to compensate for their broken one was not an option. A shutdown would disrupt water supplied to hundreds of buildings in the heart of city’s business district, thus affecting hundreds of buildings — including thousands of residents and business customers — while also limiting fire protection, making a large portion of the city vulnerable.
At the recommendation of State Utility Contractors, Hydra-Stop’s Insta-Valve 20-24 was chosen for this project to allow the installation contractor, Garrison Enterprises, to make the appropriate repairs while maintaining service for the city’s residents. The Insta-Valve 20-24 — a permanent, resilient seated wedge insertion valve — was installed next to the broken butterfly valve in just four hours and allowed the water to be temporarily rerouted. Full shutdown to the work site was achieved without disrupting service to the surrounding area.
The Insta-Valve 20-24 provided targeted control for maintenance, without disrupting service to a large residential and business district.
Insta-Valve 20-24 remains a permanent, reusable asset for the city.
Widespread shutdown was avoided as well as the costs associated with shutdown, including boil orders, loss of treated water and lab testing fees.
