Overview

Please note, This instructor-led course has specific dates and times:
This course is held online over 4 days on the following schedule (All times in Eastern Time Zone):

Day 1-3 10:00 am to 4:30 pm Eastern Time (40 minute lunch + two 10 minute breaks )
Day 4, 10:00 am – 3:30 pm Eastern Time (40 minute lunch + two 10 minute breaks)

After participating in this course, you will be able to:

  • Solve fundamental pumping system design problems, including considerations for installation, operation and maintenance
  • Select the most suitable equipment for your application and write practical specifications
  • Maximize effective operational procedures and optimize the use of system controls
  • Reduce your maintenance problems and enhance system protection
  • Make condition assessment and upgrades to increase capacity

Description
Design criteria for wastewater pumping systems include the capacity to deal with variable flow rates and types, floatable objects, large solids and abrasive materials. The outcome of the design should be a suitable pumping system comprising efficient equipment, cost-effective installation, smooth operation and minimum downtime with regular maintenance. The hands-on design problems that you solve in this seminar/workshop under instructor guidance enhance your understanding of design procedures.

You learn to select the most suitable equipment for your application and appreciate the effect of design on installation, operation and maintenance.

  • Managing breakdown and injuries emergencies

Condition Assessment of Existing Pumping Facilities

  • Comprehensive investigation of all aspects
  • Application to an actual pump station
  • Checks to be made on process mechanical, building mechanical, electrical, structural, process control and ancillary systems and force main

Design Workshop
A scenario for the Hands-On Design exercise will be presented to the participants

In small groups, you will apply the principles learned in the earlier sessions to conceptually design a pumping station under instructor guidance. For the given hands-on exercises, you learn the design procedure, make design calculations to get a feel for the reasoning involved and understand equations and the nature of the quantities by going through the following steps: analyze incoming flow data, select design flows, size force mains (type, size), calculate system curves relevant to the incoming flows, select pumping equipment.

Design Workshop Continues
Group Representatives Present Their Design to all Participants Which is Followed by a Discussion on Good Versus Bad Design Practices, Practical Operation and Cost Implications

Supervisory Control and Data Acquisition (SCADA)

  • Data acquisition
  • Equipment control
  • Instrumentation
  • Alarm handling
  • Communications systems
  • Remote monitoring (types and installation considerations)
  • Backup systems - both local and disaster planning and business continuity

Troubleshooting a Pumping System

  • Troubleshooting methods
  • Root cause failure analysis
  • A basic checklist will be presented, which will be further developed by involving participants who will apply it against a scenario provided to them.
  • Investigation and diagnostics technology

Questions and Answers and Feedback to Participants on Achievement of Learning Outcomes
