Water Master Plan & System Model
As Missouri’s fastest-growing city – and among the fastest-expanding in the nation – the City of Wentzville faced the challenge of adapting its water distribution system to keep pace with rapid development. This effort required balancing immediate service demands with long-term infrastructure planning to maintain efficiency and reliability.
To meet these needs, the City selected CMT to develop a water master plan powered by an advanced WaterGEMS model. The resulting plan provided a data-driven strategy to optimize system performance, prioritize improvements, and support sustainable growth.
Collaborative Planning & Advanced System Modeling
This project required a highly detailed hydraulic modeling effort, paired with close collaboration between CMT and City staff to align planning efforts with real-world system operations and future growth.
Key aspects of the Water Master Plan & System Model included:
- Hydraulic Model Development & Calibration – CMT updated and refined the City’s WaterGEMS model, integrating the latest GIS watermain data and calibrating it using hydrant pressure testing.
- Growth & Development Projections – Future system needs were modeled using Wentzville’s comprehensive plan, zoning data, and anticipated growth patterns.
- Scenario-Based System Analysis – The model evaluated the system under average day and maximum day demands, identifying pressure, fire flow, and capacity improvements.
- Extended Period Simulation (EPS) – A dynamic model assessed water age, system operations, and emergency response scenarios to support long-term reliability.
- 5-Year & 10-Year Capital Improvement Plan – Model-driven insights helped prioritize infrastructure investments, balancing immediate service needs with future expansion.
A Roadmap for the Future
The final Water Master Plan & System Model delivered a strategic, data-driven framework to guide Wentzville’s water infrastructure investments for the next decade and beyond. CMT combined engineering expertise, advanced modeling, and collaborative planning to develop a practical, actionable plan that provides reliable, high-quality water service now and into the future.
This collaboration builds on a deep legacy that includes major water supply and treatment planning efforts, such as CMT’s leadership in the major expansion of the City’s water treatment plant in the early 1990s. As Aurora continues to grow, CMT remains committed to positioning its water infrastructure for the future, delivering reliability, efficiency, and long-term sustainability.
