SUBJECT
recommendation
Authorize funding for an engineering services agreement for design of the Wylie Water Treatment Plant (WTP) Raw Water Pump Station No. 3 Improvements project.
end
PURPOSE
The proposed improvements will replace aging infrastructure and upgrade certain systems to current NTMWD’s standards. Condition-related improvements are needed to maintain a high level of service for the largest raw water pump station at the Wyle WTP. Replacement of some electrical and control equipment that have reached their service life or have increased risk of failure will improve reliability of the pump station.
RECOMMENDATION
The Executive Director and NTMWD staff recommend the Board of Directors authorize the Executive Director to execute an engineering services agreement (ESA) as follows:

BACKGROUND
Lavon Raw Water Pump Station No. 3 (RWPS No. 3) is the largest of the District’s raw water pump stations at Lake Lavon and is an integral component of the movement of raw water supply system from Lake Lavon into the Wylie plants. The improvements are recommended in order to replace aging infrastructure and provide critical upgrades to certain systems.
PROJECT PURPOSE
• Maintain the useability and functionality of RWPS No. 3
• Upgrade infrastructure to current NTMWD standards
• Project identified by the Raw Water CIP and Implementation Plan
• The planning level estimated construction cost for the project is $7,826,000
PROJECT COMPONENTS
• Mechanical - replace the heating, ventilation, and air conditioning (HVAC) systems at the North/South electrical buildings, replace electric motor operators, installation of pumping screens and hydrocones at the wet well
• Electrical - replace the motor control centers (MCCs) and station transformer in the pump building
• Instrumentation and Control - replace the programmable logic controller (PLC) and the uninterruptible power supply (UPS) in the pump building and replace the PLC in the North/South electrical buildings
• Structural - replace pump station roof
• Site Civil - grading and drainage repairs, replace damaged fence
