Barclay Neighborhood Water Main Replacement

Location: Baltimore, MD

Recently, residents have had to reconsider the need for personal water storage since there has been on average about 1,000 breaks annually throughout the 4,500 mile network of underground water mains in the City.Old vs. New Water Main Pipes

As part of a concerted effort by the City to increase system reliability and water quality, about six miles of the 4,500 mile network will see remarkable transformation. In 2015 CCJM was retained to provide full engineering design services for the the replacement of the water mains, ranging from 6″ to 20″ pipe, in the Barclay Neighborhood, one of the areas of greatest risk for system failure.

To accomplish this, CCJM surveyors performed full site survey of about 25 acres in the heart of the City. This work also included site inspections, evaluation of vacant lots and buildings and verifying Right of Way limits. Once completed, the design team sited the new water main after evaluating the existing site conditions, available construction methods in a dense urban landscape and coordinating with the Project Owner and other City officials.

CCJM’s design team evaluated the existing site and coordinated with the City to eliminate 2,500 linear feet of redundant water mains, while still meeting all of the project requirements. This resulted in a more effective water system and an overall construction cost savings of almost $800,000

The project also involved public outreach coordination, thrust restraint design, evaluation of meter data, test pit coordination, cost estimation, and careful scheduling coordination.

CCJM worked with City officials to ensure all efforts were taken to minimize impacts to the residents and businesses in the community. The new pipelines will bring the existing water pipes or mains up to modern standards, reduce maintenance requirements and accommodate community growth.
