SUBJECT
recommendation
Authorize funding for an engineering services agreement for the design of the Shiloh Pump Station Improvements, Phase I Project.
end
PURPOSE
The proposed improvements will replace aging infrastructure and upgrade certain systems to current NTMWD’s standards, including the addition of a new emergency backup power. Increased service demands for this facility and condition related replacements of critical elements of this facility necessitate these improvements to maintain NTMWDs ability to serve the Shiloh System.
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
The existing 3-million-gallon (MG) ground storage tank (GST) was constructed in 1969 and a subsequent project (No. 101-0306-12) was completed in 2017 to perform pump station improvements and minor leak repairs to the tank. The tank is considered to have reached the end of its service life and is recommended for removal.
PROJECT PURPOSE
• Define and implement infrastructure improvements to the pump station and meter vaults to meet increased consumer water demands to the Richardson and Plano delivery points from the Shiloh Pump Station.
• Evaluate items that may be in poor or failing condition and develop appropriate rehabilitation or replacement plans.
• Provide improvements to fulfill operational capabilities defined in the NTMWD Emergency Preparedness Plan submitted to the Texas Commission on Environmental Quality (TCEQ).
• The planning level estimated cost is $19,286,000.00.
PROJECT COMPONENTS
• Design flow control vault including, isolation and flow control valves.
• Demolition and bypass pumping plan for the existing 3-MG ground storage tank
• Update physical security capabilities at the site
• Provide a new emergency backup generator
• Improvements to the Richardson delivery vault radio and panel
• Replace Pump Nos. 203 and 204 due to advanced deterioration
