Testing of the town’s emergency water connection March 7-9 might cause discoloration as water flows through lines from the opposite direction.
Town engineers and Public Works crews will be watching for any changes in pressure.
The water will remain safe to drink. Call the Public Works Department at (919) 552-5920 with questions or concerns.
Ordinarily, Holly Springs gets all of its water from Harnett County, which draws from the Cape Fear River. However, the town maintains a link to the Cary-Apex water system as a backup.
The system test is preparation for a 5-7 day switch-over to the Cary-Apex system when Harnett County empties its storage tanks for cleaning. That is expected in March. The Cary-Apex plant draws from Jordan Lake.
Water system interconnections allow municipalities to help each other in emergencies such as treatment plant malfunctions, pipeline breaks, and during severe drought.
In 2008, Holly Springs turned to its neighbors for help after an equipment malfunction and major line rupture knocked the Harnett County plant out of service. The town resumed buying water from Raleigh, a former supplier, and from Apex temporarily.
Going forward, the town plans to test its backup connections annually, checking for any weak spots in the distribution system.
