The seminar/workshop presents case studies on rehabilitation & odour control utilizing bio-filtration of a wastewater pumping station. Besides detailed lecture notes, you receive a troubleshooting checklist which will serve as a reference material.

Course Outline

After participating in the course you will be able to do the following:
solve basic pumping system design problems
select the most suitable equipment for your application
write practical specifications
maximize effective operational procedures
optimize use of system controls
reduce maintenance problems
enhance system protection
use a troubleshooting checklist developed in this course
assess conditions
increase capacity by upgrading

The design criteria for wastewater pumping systems include the capacity to deal with variable flow rates/types, floatable objects, large solids, and abrasive materials. A suitable pumping system should be the result of a design that yields efficient equipment, cost-effective installation, smooth operation, and minimum downtime with normal maintenance.

This course offers hands-on design problems under instructor guidance. You will learn to select the most suitable equipment for your application, to control and protect pumping systems, and to appreciate the effect of design on installation, operation, and maintenance. Case studies cover rehabilitation and odour control using bio-filtration of a wastewater pumping station.

To present design criteria that will develop cost-effective installations, improve operational procedures, and minimize maintenance problems.

Who Should Attend
Design engineers, pumping plant superintendents and operators, water resource engineers, wastewater utility managers, city and town engineers, consulting engineers, project managers, environmental engineers, collection system maintenance engineers, managers of technical services, technicians and technologists, approval agency plan reviewers, and other individuals involved with municipal or industrial wastewater management.

Special Feature
Besides detailed lecture notes, you will receive a troubleshooting checklist which will serve as reference material for the future.

Please bring your hand-held calculator for faster calculations.

              involved and understand equations and nature of the quantities by going through the following steps: analyse incoming flow data, select 
              design flows, size force mains (type, size), calculate system curves relevant to the incoming flows, select pumping equipment, estimate 
              cost and select most efficient pump set, mechanical/electrical aspects including SCADA considerations, develop station layouts

The course was very well presented and the course instructor was absolutely amazing.
Reviewed by 2013
Our instructor, Stephen Lamming, was outstanding and a true expert in his field. He was able to complement the technical air monitoring information with practical real life examples which was highly beneficial. He is an excellent communicator and was highly interactive with the course attendees. This course was recommended to me because Stephen Lamming does an outstanding job. I was very impressed with this course and have subsequently recommended it to my colleagues.
