Safe Yield & Water Supply Investigations

Good water supply decisions depend on complete, accurate data – especially as municipalities, utilities, and private industry face scarcity, conservation, drought, and financial concerns. We perform detailed studies to provide the statistical information you need for water supply reliability and performance. And we go beyond the engineering to guide you through permit condition negotiations, maximize your operations, and develop new supply sources.

Our Expertise

Our clients benefit from our extensive experience in water supply investigations to adequately estimate yield, assess the economic aspects of supply options, identify opportunities for reuse, and understand impacts on other water usage. In the last 15 years, we’ve completed more than 30 studies ranging from a single reservoir to complex composite systems comprised on multiple reservoirs wells, river intakes, and transmission facilities. We collect extensive hydraulic, hydrologic, and system operational data and develop custom programs to evaluate and optimize operating rules and in-stream regulatory flow requirements.

    Custom Application Development

    We develop custom applications to simulate the daily operation of each unique supply system. These applications can integrate economic analyses not available in out-of-the-box solutions, which enable our clients to optimize safe yield under drought conditions and per operating costs. Our clients use these applications as a basis for operating decisions, such as which raw water source to use and whether to turn on pumps or open gates.
