Program Background

Concord's water distribution system consists of over 130 miles of water main ranging in size from 6-inch to 16-inch.  The associated infrastructure (mains, valves, hydrants.)  have been installed over a period of 100 years. To maintain safe and reliable service, this aging infrastructure must be replaced or rehabilitated systematically.  Replacement/rehabilitation projects are prioritized based on age, condition and material of pipe.  The program is further refined to complement other public works initiatives such as annual roads and drainage improvements as well as CMLP underground initiatives. 

Project Overview

The existing 8-inch cast iron water main in Monument Street between Liberty Street and approx. 800' north of Red Coat Lane was installed in the early 1930's.  After 85 years the water main has been in service well beyond it's useful life as evidenced by the history of water main breaks in recent years.  The project, valued at approximately $300,000 involves the replacement of approximately 1,600 linear feet of existing 8-inch water main with a new 12-inch cement lined ductile iron water main.    

Scope of Work

The replacement of approx. 1,600 linear feet of existing 8-inch water main with new 12-inch diameter CLDI water main including the installation of three (3) hydrants, four (4) main isolation valves and seven (7) service connections within the project limits.  Drainage improvements consist of the replacement of three (3) catch basin structures and the installation of one (1) new drain manhole structure.  Following the installation of the water and drainage the utility trenches will receive a permanent pavement patch.


N. Cibotti Inc. has completed the installation of the water main on Monument Street between Liberty Street and Red Coat Lane.  During the week of October 17th Cibotti will continue with the installation of the water main in the southbound lane of Monument Street progressing north from the Red Coat Lane intersection toward the new connection with the existing water main.  Cibotti will also be completing drainage improvements within the project limits. Construction activities will be conducted Monday through Friday this week.  During construction activity traffic along Monument Street will be restricted to one alternating lane and delays should be expected.  Commuters are advised to seek alternate routes.
