Explanation
1. BACKGROUND: This legislation authorizes the Director of Public Utilities to enter into a professional engineering services agreement with Black and Veatch Corporation, for the Hap Cremean Water Plant (HCWP) Intake Structure and Low Head Dam Rehabilitation Project, in an amount up to $336,750.00, for Division of Water Contract No. 2086.
Black and Veatch will provide services for study and condition / needs assessment, detailed design, and construction administration services to improve plant intake debris removal and for the repair of deteriorated concrete and other defective components at the intake facility and dam.
Debris from the Big Walnut Creek accumulates on the plant’s intake bar screens and is periodically manually raked from the screens. The consultant will evaluate options (including mechanical removal systems) and recommend an approach to reduce amount of debris that accumulates at the intake and to improve debris removal to make the operation safer and less labor intensive.
Additionally, a condition assessment will be performed on all aspects of the intake facility and dam including, but not limited to: roof, doors, and windows of the intake building, pedestrian walkways, grating, hatch covers, handrails, guardrails, security fencing, lighting and other electrical accessories, stop logs, monorail system, flashboards, dam structure, trash booms, bar screens, debris removal equipment, water sampling equipment and associated pedestrian accesses, both 72-inch and 84-inch raw water conduits from the intake to the treatment facility, and feed lines from the Powder Activated Carbon (PAC) facility to the raw water intake. Black and Veatch will evaluate the Big Walnut Creek stream corridor upstream and downstream of the intake for erosion and sedimentation issues which could adversely impact operations and structural integrity of said infrastructure.
FUTURE MODIFICATION(S): Modification No. 1 for Detailed Design is expected in 2019...
