Horizon Hill - Water

Purpose: This project funds the design and reconstruction of the water main in the Horizon Hills neighborhood based on on-going maintenance issues. A cast iron pipe on Sunrise Drive failed in 2003. A forensic analysis of the pipe concluded that graphitic corrosion on the exterior of the pipe caused the failure. Additionally, the rest of the cast iron pipe in the area is likely subject to the same potential mode of failure. The extent of the problem has not yet been determined.

First Appeared in Rockville's Capital Improvement Program: Fiscal Year 2005.

Staff Contact: Department of Public Works. John Hollida, Civil Engineer II, 240-314-8500.
