TRAINING.

Overview

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

• Solve basic 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 assessments 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 normal maintenance. The hands-on design problems 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.

Troubleshooting a Pumping System

• A basic checklist will be presented which will be further developed by involving participants who will apply it against a scenario provided to them.

Options to Upgrade or Increase Capacity of Existing Facilities

• Refurbishment, Retrofitting and Replacement Decisions will be discussed

Pump Station-Inspection and Maintenance

• Types of maintenance will be discussed
• Inspection procedure
• Preventive maintenance
• Computerized Maintenance Management Systems and their impact on the maintenance inspection process will be discussed
• Managing breakdown and injuries emergencies

Pump Station Case Study - Rehab/Force main/Metering

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, estimate cost and select most efficient pump set, mechanical, electrical, control and monitoring aspects including SCADA considerations, develop station layouts

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

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