COURS.

APERÇU

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

• Address fundamental challenges in pumping system concept development and design, considering installation, operation, and maintenance requirements.
• Identify and select the most suitable equipment for your applications, creating detailed technical specifications.
• Optimize operational performance by enhancing the efficiency and integration of system controls.
• Minimize recurring maintenance issues and improve overall system reliability and protection.
• Conduct thorough condition assessments and implement effective upgrades to increase pumping capacity.

Description
Wastewater pumping systems must manage varying flow rates, handle floatable objects, large solids, and abrasive materials, and minimize downtime and operational costs. Designing an efficient system involves development of the optimal concept, technical sound detailed design and selection of suitable equipment, for cost-effective installations, and smooth operation. This course delves into pump station design fundamentals, covering essential topics like applied hydraulics, pumps, motors, variable speed drives, and odour control technologies.

You will explore various pumping station types and their applications, including system head calculations, troubleshooting techniques, and ways to reduce maintenance demands. Case studies on odour control and options to upgrade existing facilities provide real-world insights into pump station operation and maintenance. Additionally, hands-on design exercises will guide you through sizing force mains, selecting appropriate pumps, and applying design principles to improve system functionality.

By the end of this course, you'll be equipped with practical knowledge to assess and upgrade pumping stations, implement supervisory control and data acquisition (SCADA) systems, and troubleshoot common issues. The design workshop allows participants to apply the principles learned in earlier sessions, culminating in a collaborative presentation and discussion on best practices in pumping station design.

Who Should Attend
This course is ideal for engineers, superintendents, operators, and managers involved in wastewater system planning, design, operation, and maintenance. Water resource engineers, utility managers, consulting engineers, project managers, and environmental engineers will find the content highly relevant to their roles. Collection system maintenance engineers, technicians, technologists, and approval agency plan reviewers will also benefit from the practical, hands-on aspects of the course.

Additionally, professionals responsible for upgrading or maintaining pumping facilities, implementing control systems, or optimizing system efficiency will gain valuable insights. This course will help individuals across various sectors, including municipal water services, private engineering firms, and environmental consultancies to enhance their wastewater pumping systems expertise.

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 design a pumping station under instructor guidance conceptually. 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.

Group representatives present their designs to all participants, followed by a discussion on good versus bad design practices, practical operations, and cost implications.
