Course Overview

Reliable and well-designed wastewater pumping facilities are essential for cities and sewerage systems across the United States. This course will provide you with valuable techniques and knowledge that you can apply immediately in your own systems and projects. This course will help you: 

  • Manage, design, and operate reliable and cost effective pumping facilities and forcemains 
  • Evaluate pros and cons of different station designs 
  • Prevent hydraulic problems in pumps, wet wells, and forcemains 
  • Improve station reliability 
  • Understand electric motors and VFDs 
  • Reduce problems in operation and maintenance 
  • Select optimum pumping equipment, valves, and piping systems 
  • Reduce your pumping energy costs 
  • Upgrade and rehab your pumping stations for the future

Who Should Attend?

  • Wastewater engineers, operators, and managers
  • Consulting engineers
  • Federal agencies and military bases
  • Regulatory staff

Testimonials

"A terrific course. Best I've ever had."

"A fantastic course! A must-attend for all that are planning, designing, or operating a sewage pumping station."

"I will be applying what I learned almost immediately when I get back to the office."

"Well done workshop. Put together superbly."

"I've never seen a better technical speaker. It's one thing to present material to college kids, and quite another to present design concepts to PE's with 25 years of experience and O&M personnel with the same. Ned did a masterful job."
