SUBJECT
recommendation
Authorize funding in the amount of $1,493,100 to Black & Veatch Corporation for an engineering services agreement (ESA) for final engineering design services of the Transmission System Valve Improvements project.
end
PURPOSE
The purpose of the project is to design the installation of new valves or replacement of some existing valves at 15 different high-priority locations within the Water Transmission System. These critical isolation valves are essential to ensuring system reliability, operational flexibility, and safety by allowing for the effective isolation of pipeline segments during system shutdowns.

BACKGROUND
The existing Water Transmission System, consisting of over 700 miles of pipelines, has created challenges for routine maintenance, tie-ins, and hindered scheduling of shutdowns due to older valves requiring repairs or replacement, or the need for additional valves for proper shutdowns.
Administrative Memorandum No. 25-6181 authorized an ESA in September 2025 for preliminary engineering services to evaluate the isolation valves within the Water Transmission system and develop an Immediate needs, repair and/or replacement plan, and a Long-term valve improvement plan to Black & Veatch Corporation, in the amount of $1,099,535.
PROJECT PURPOSE
• Based on recommendations from the immediate needs, repair and/or replacement plan developed in preliminary engineering, prepare final design documents for up to 15 critical isolation valves to improve operational efficiency for future shutdowns and maintenance of the Water Transmission system, that are expected to be installed within one shutdown season.
PROJECT COMPONENTS
• Final design of up to 15 critical valves identified in the plan, including all associated civil, structural, and corrosion protection improvements.
