Saving Pipelines & Pump Stations Before It's Too late

Analyzing System Response Time through Modeling and Developing Response Strategies

Thursday, April 19
10:25 AM - 10:50 AM
Location: Meeting Room 315, Sacramento Convention Center

CWEA: .5 Contact Hours

Practice Area: Professional Challenge Area: Collection Systems

HDR developed a pump station response time model for Tahoe City Public Utilities District to support prevention of overflows due to pump failures in this critical region next to Lake Tahoe. The results allow the District to plan and predict problems which could otherwise result in a system overflow.

Learner Outcomes:

Level: Intermediate; working knowledge of subject matter / journeyman level staff
