Course Description:
Wastewater lift stations are a necessity in many communities. In areas with limited elevation differences, many lift stations may be required, varying from quite small to very large. Even in communities with adequate overall slope, there are frequently areas that won’t drain by gravity to the rest of the system. Lift stations are also very common near the end of the collection system, to lift the wastewater into a treatment facility. This course provides a comprehensive overview of all of the components of a lift station. It provides design guidance for these components, including the wet well, pumps, force mains, odor control, electrical systems, instrumentation and controls and site layout.
Course Outline:
Flow Analysis
Hydraulics
Mechanical Systems
Odor Control
Electrical System
Instrumentation and Controls
Site Layout
Learning Objectives:
At the conclusion of this course, the user will:
Understand how design flows for a wastewater lift station are determined
Understand the hydraulic concepts of a lift station, including the wet well and pumping system
Become familiar with the mechanical systems in a lift station, including the pumps, force main, valves, flow meters, gages, yard piping, HVAC and noise control and abatement.
Understand the basics of odor generation in a wastewater lift station and how to control those odors.
Understand what electrical system components are necessary and how to determine the need for standby power.
Understand the concepts behind the necessary instrumentation and controls for a lift station and the site layout concepts.
Prerequisites:
There are no special prerequisites.
Intended Audience:
This course is intended as a general guide to design of wastewater lift stations therefore the intended audience includes all engineers involved in design of these facilities, regardless of discipline. It is useful to all disciplines to understand the various components of a lift station to see how their specialty impacts the overall station performance. It also includes those engineers and managers responsible for reviewing lift stations.
Course Summary:
This course provides a comprehensive overview of the components of a lift station. It includes design guidance for most of these components, including the wet well, pumps, force mains, odor control, electrical systems, instrumentation and controls and site layout. This course provides a good checklist of items that need to be included in the design to help eliminate the potential for a key component to be overlooked until late in the design process.
