About the Project
This project is the second phase of the Gravity One Supply project, identified in the County’s Water System Master Plan, dated September 2014, as Project B. The first phase of the project was completed in August 2017. The Transmission Main proposed with this Gravity One Watermain Phase Two project will serve as backup to the existing 30-inch main that feeds the Lee storage tanks and pump station located at 24th St. N. and N. Wakefield St. The 30-inch transmission main being replaced is a pre-stressed concrete cylinder pipe (PCCP) built in 1957 and the installation of the proposed main will allow the performance of condition assessment inspection of this critical existing pipe and isolation for maintenance as needed.
The 24-inch water transmission main is being installed in the Right-of-Way of North Taylor Street, Vacation Lane, North Vermont and North Vernon Streets between Lorcom Lane and 25th Street North. The contract also includes installation of a new 8-inch water main to replace existing 6-inch water main along North Vernon Street between 25th Street North and North Vermont Street.
About the Process
The scope of this project involves the rehabilitation of existing infrastructure along the same corridor and the construction, which began in April 2021, requires some water service disruptions throughout the duration. These disruptions are not for an extended period and residents of Donaldson Run are being notified in advance. Traffic flow is being maintained throughout the project duration. Residents of the Donaldson Run community continue to be informed of scheduling. All shutdowns will be limited to the same daily construction work hours.
Funding
This project is budgeted in the Utilities portion of the Capital Improvement Plan (CIP). Sufficient funds are available in the Utility Construction Fund and the Water Bond Fund to provide for the construction of this project.
