Maroon Bell - Winchester Water Main Replacement Project

Analysis has shown that the construction methods used in establishing the system were of poor quality. The water main is concrete mortar lined and coated (CMLC) steel pipe. The steel pipe is exposed at points where appurtenances and services are connected without follow-on protection for the exposed metal. The result is that the pipeline failures have occurred where the exposed metal has corroded due to the corrosive soil.

Project Description:

The work comprises, but is not limited to: Mobilization; traffic control; installation of approximately 3,900 LF of 8-inch PVC C900 DR 14 pipe, including gate valves, fixtures, appurtenances, thrust blocks, blow off, and air vac assemblies, and removal of portions of existing pipe. In addition, the work consists of installation of 111 EA 1-inch copper water service laterals and connecting to existing meters; installation of fire hydrants and valve assemblies, abandon-in-place existing water mains, pressure testing, disinfection, BacTs; trenching and pavement restoration, crack seal, slurry seal application, replacement of concrete cross gutter, speed hump, and restoration of pavement markings, raised markers, and striping; and other necessary work to complete the water replacement and street improvements.
