BACKGROUND
Rapid and sustained growth in the NTMWD service area requires that the District periodically perform a comprehensive review and update to its CIP for the water treatment plants and treated water transmission system.
This study will incorporate the updated population and demand projections, changes in regulatory or policy requirements, and assessments of treatment and transmission system performance, capacity, and condition, and identify and prioritize the improvements required to maintain adequate capacity, ensure system reliability, and support long-term regional growth.
PROJECT PURPOSE
• Identify, evaluate, and recommend improvements to the WTPs and the treated water transmission system
• Incorporate the recommendations into the Regional Water System CIP
PROJECT COMPONENTS
• Coordinate with Long Range Water Supply Plan Update study to update population and water demand projections
• Evaluate and define levels of service
• Conduct a comprehensive assessment of Wylie, Tawakoni, Leonard, and Bonham WTPs
• Update and recalibrate the treated water transmission system hydraulic model and perform model analyses
• Conduct surge analysis of portions of the treated water transmission system
• Develop and evaluate treatment and transmission improvement alternatives
• Perform a multi-criteria cost-benefit analysis
• Develop a prioritized systemwide CIP project list
BASIC SERVICES
• Project management and coordination with other consultants/agencies as necessary
• Coordination with stakeholders
• Site visits to related facilities
• Workshops
• Technical memorandums and final report
SPECIAL SERVICES
• Owner-directed services for additional meetings, presentations, testing, assessment, analyses, and additional services.
