Update on Interruption to Water Service Caused by Pipe Failure

7/31/2014

NASHVILLE, Tenn. – Mayor Karl Dean and Metro Water Services Director Scott Potter provided an update to media this morning on a major interruption to water services to 15,242 customers in the west and southwest portions of Davidson County caused by a catastrophic pipe failure.

“In order for all homes and businesses to have sufficient water pressure, we are now implementing a strict no-irrigation policy in the affected area until permanent repair work is complete,” Mayor Dean said. “People who don't abide by this policy are hurting their neighbors and fellow Nashvillians by using water others need for essential uses.”

  • Many customers in the affected area are experiencing close to normal water pressure. A small number of customers at high elevation are seeing a reduction in water capacity.
  • Homeowners and businesses in the impacted area are being instructed to not irrigate until water service is restored to full capacity in order to ensure all customers have sufficient water pressure. People are asked to only use water for essential needs, such as drinking, cooking and bathing.
  • The temporary system is providing enough water so that businesses are able to operate normally during this time while a permanent fix is underway.
  • Metro Water Services customers not located in the affected area do not need to take additional measures to conserve water.
  • Metro Water Services has implemented a temporary fix that includes building temporary bypasses around the Thompson Lane pumping station. As part of that temporary fix, two temporary pumps have been put in operation and a third is under construction.  Additional valves have been opened to help increase water availability in the affected area.
  • Work began last night and is continuing this morning to prepare the site around the broken pipe for construction to begin on a permanent repair. A temporary gravel road is being constructed to the broken pipe and excavation work will begin soon.
  • At 10 a.m. this morning, bids for the repair work are due, and Metro Water will move forward with hiring a contractor to repair the pipe.
  • An exact timeline for the repair will not be known until a contractor is hired, but it could take several days to complete.
  • An estimated 11,000 bottles of water to 340 households have been distributed since 5 p.m. on Wednesday, July 30, when two water distribution centers opened. Metro's Office of Emergency Management is operating distribution centers at Crieve Hall Elementary School, 498 Hogan Road, and Hillsboro High School, 3812 Hillsboro Road. Representatives from OEM and Public Works, along with deputies from the Davidson County Sheriff's Office, are distributing water at the two locations 24 hours a day until water service is fully restored.
  • Affected homeowners who are homebound, who have no way to pick up the bottled water or have other needs should call OEM's helpline at 862-8750 (not 311) for assistance.

Background regarding interruption to water service

  • Interruption of services was caused by pipe failure late morning on Wednesday, July 30, in a 30-inch pipe that connects Metro's pumping station at Thompson Lane to numerous other pumping stations that serve Green Hills, Forest Hills, Oak Hill and portions of Crieve Hall.
  • The affected area largely includes the parts of Davidson County that are south of Interstate 440 and north of the Williamson County line between Harding Pike/Highway 100 to the west and Interstate 65 to the east. Portions of the Crieve Hall neighborhood east of I-65 also is affected.
  • The broken pipe is located behind the Home Depot at 2535 Powell Avenue off Thompson Lane in a wooded area that is difficult to access.
  • The broken pipe is a pre-stressed concrete cylinder pipe (PCCP) that was installed in 1973 when I-65 was constructed. Metro Water will be replacing a full length of the pipe.
  • Metro Fire Department has set up a command center at Hillsboro High School and deployed additional resources to the area.
  • Fire department tankers filled with water have been moved to fire halls throughout the affected area. Additionally, two 8,000-gallon tankers from Water Services and Public Works have been relocated to fire halls in the affected area.
  • Firefighters will monitor critical buildings in the affected area, including senior living centers, high rises and multi-resident complexes dependent on fire sprinklers for safety.
  • Metro Police has put extra officers and resources in the affected area to assist Metro Fire and with water distribution to homebound persons.
