Pumping 101: Basic and Advanced Wastewater Pump Station Design and Operation

Sunday, October 19, 8:30 am – 4:30 pm
1 day, 0.6 CEUs

Improperly designed wastewater pumping stations all too often result in excessive maintenance costs and loss of reliability. Pumping 101 has been conceived as a basis for identifying design flaws, poor operational practices, and faulty maintenance procedures.

The course will focus on proven design as well as operational and maintenance techniques for successful installations. Engineering design professionals and pumping equipment manufacturers will share their unique perspectives and experiences.

Multiple interactive pumping demonstration units will be used by workshop attendees to observe the affects of suction cavitation, discharge cavitation, vortexing, entrained air, variable speed operation, and other hydraulic phenomena. Each attendee will have the ability to interact with these hands-on demonstration units.

Proper wet well sizing, location, and number of gravity influent lines, selection of
appropriate pumping equipment for varying hydraulic requirements, placement of the equipment, best practices for piping/valve layout, Hydraulic Institute guidelines, confined space considerations and safety concerns are included in the design presentation portion of the course.

Dry-pit, self-priming, and submersible pumping technologies will be presented, with attention given to the specific advantages and disadvantages of each basic design.

Hydraulic, efficiency, and power consumption advantages gained through the use of variable speed drives will be discussed. Variable speed technology developments in recent years have dramatically improved the reliability of the equipment and driven costs down. However, care must be taken when applying variable speed equipment to wastewater pumping stations.

Modern wastewater pumping stations are “not your father’s lift stations”. Proper
operations and maintenance techniques are at least as important as the design, in assuring an efficient installation. Remote monitoring, predictive/preventative
maintenance programs, and the importance of keeping valid records are topics included in the course material.

Finally, Pumping 101 will strive to apply the above topics to new (under design) and existing wastewater pumping stations. The subject matter of the workshop applies to low pressure sewer and conventional wastewater pumping stations.
