Description
The City of Jamestown hired LDA Engineering to develop plans for a new electrical building for their raw water intake to isolate the electrical equipment and system controls from the pump room. Through the design process, further upgrades were recommended including the installation of a new emergency generator pad, improvements to the intake site driveway approach, addition of variable frequency drives, and the installation of new check dams to improve the operation of the intake.
The City of Jamestown owns and operates a water treatment facility that provides water to the City of Jamestown and portions of Fentress County through the Fentress County Utility District and the City of Allardt. Intake electrical equipment is currently located in the pump room of the intake structure, above the Jamestown Reservoir. The existing raw water intake facility was originally constructed in 1970 with some improvements / expansions in 1980 and 1996. Many of these facilities are original to the 1970 construction. The operational and maintenance requirements of the intake have increased significantly over the last several years in addition to the catastrophic failure of the intake in 2014 following a pump failure that submerged the electrical system.
The new raw water intake electrical building will be an approximately 10’ x 25’ concrete block building. The new electrical building will house the pump control panel, the motor control center, and all other vital electrical equipment which was originally housed in the raw water intake structure. This new electrical building will prevent a catastrophic pump failure from damaging the electrical equipment. All electrical equipment housed in this building will also be placed atop 4” housekeeping pads. A wall mounted HVAC unit will be attached to this building to maintain adequate temperatures within the electrical building. A new 9’ x 23’ concrete pad will be built to allow for the installation of a new generator.
