Carriger Street Water Line Extension

 LOCATION: Morristown, Tennessee

 KEY PERSONNEL:

• Steve Bostic

 DATES: 2010

 CONSTRUCTION COST: $4.3 Million

 PROJECT HIGHLIGHTS:

• 6 Stream Crossings
• High Volume Areas
• Improved Water Quality

The project involved connecting the Carriger Street Reservoir to water mains feeding the Arnold Hills reservoir, which experienced excessive draw-down during daily demand cycles.  Both of these reservoirs are located in the eastern portion of the Morristown Utility Commission service area, and provide storage for an additional booster station serving a higher (elevation) pressure zone, the Walters State Community College, numerous residential and commercial customers, a neighboring utility district, and the East Industrial Park.

This project consisted of approximately 13,500 linear feet of 24-inch water main and appurtenances.  Design challenges included routing the large diameter main through congested city streets, commercial areas, and six different stream crossings.  Adding to the complexity of the project, bored and jacked crossings of U.S. Highways 25-E,11-E, and the Norfolk Southern Railroad were required.

As a result of this project, the Arnold Hills reservoir maintains a more consistent water level, the Carriger Street reservoir experienced improved water quality through better “turnover”, and the eastern portion of the Morristown Utility Commission service area has an improved level of water service.  LDA also prepared easements and negotiated the acquisitions on behalf of Morristown Utility Commission, provided permitting and bidding assistance, engineering services during construction, and resident project representation services.
