PURPOSE
Planned expansions of the Leonard Water Treatment Plant (WTP) will require an additional High Service Pump Station (HSPS) to add 175 million gallons per day (MGD), for a total of 350 MGD in treated water pumping capacity. The additional pumping capacity from the Bois d’Arc Lake system is consistent with NTMWD’s plans and efforts to continuously supply safe potable water to its growing service area.

BACKGROUND
PROJECT PURPOSE
• Add treated water pumping capacity of 175 MGD to the Leonard WTP, consisting of a second HSPS, very similar in design and scope to the existing HSPS North.
• Construction of a building to include pump level and electrical component levels that will create HSPS South.
• Improvements to the existing HSPS North facility include the installation of one high-flow/high-head horizontal split-case pump (45 MGD) with motor and ancillary equipment, replacement of manual gate valve actuators with electric actuators, and modifications to the existing Heating Ventilation and Cooling (HVAC) ductwork.
• The Engineer’s Opinion of Probable Construction Cost for Leonard WTP HSPS South is $174,694,126.
• This project will bring the total high service pumping capacity for the Leonard WTP site to 350 MGD.
PROJECT COMPONENTS
• HSPS building structure complete with mechanical, electrical, plumbing, drainage, and site work components.
• Installation of four high-flow/high-head horizontal split-case pumps (45 MGD each) with associated motors, air-cooled adjustable frequency drives (AFDs) and ancillary equipment.
• Installation of three high-flow/low-head (45 MGD each) horizontal split-case pumps with associated motors, air-cooled AFDs and ancillary equipment in the new HSPS South.
• Two submersible dewatering pumps, and associated mechanical, electrical, instrumentation, and control (EI&C) equipment and components.
• Removal and relocation of a 25 MGD horizontal split-case pump and motor, including ancillary equipment from the existing HSPS North to HSPS South.
• Modifications to the existing HSPS North HVAC ductwork.

BEST VALUE PROPOSAL
NTMWD used the Competitive Sealed Proposal Method in accordance with Section 2269 of the Texas Administrative Code, “Contracting and Delivery Procedures for Construction Projects,” to procure a contractor for this project. This method involves evaluating and scoring proposals based on key criteria, including project approach, experience with similar projects, key personnel, safety record, and price. Four proposals were received on Tuesday, February 10, 2026.
NTMWD staff evaluated the four responsive proposals in accordance with the published rating criteria. Additionally, NTMWD consultants Carollo Engineers, Inc. (Carollo), and Black and Veatch Corporation (Black and Veatch) checked company and individual team member references. NTMWD staff scored the Garney Companies, Inc. proposal as the best value for NTMWD.

Construction Phase Engineering Services for HSPS-S Project $3,524,030
Revised ESA Amount $12,004,030
INSPECTION SERVICES AGREEMENT
The engineering department normally provides inspections services for NTMWD projects. Due to the current project workload, the NTMWD staff recommended that Black and Veatch Corporation (Black and Veatch) be retained to augment and supplement NTMWD construction management and inspection staff with full-service inspection services for the Leonard WTP HSPS - South. A request for authorization of Black and Veatch’s construction management and inspection fee for services related to Bois d’Arc Lake Phase II projects was presented and approved during the March 28, 2024, Board meeting. A recommendation to augment these services will be presented in a separate Administrative Memorandum at this same Board meeting, March 26, 2026.
FUNDING
Funding in the amount of $136,220,000 to Garney Companies Inc. and additional funding in the amount of $3,524,030 to Carollo Engineers Inc is to be made available in the Regional Water System SWIFT Construction Funds contingent upon Texas Water Development Board approval of the contract and release of funding.
