Learning Objective

At the conclusion of this course, the student will:

• Learn about the approach, requirements, criteria, considerations, and hydraulic calculations used in the design of gravity sewers;
• Learn about alternatives to gravity sewer systems that would require deep and expensive trench excavation, such as jacking, boring, and tunneling;
• Learn how the operation and maintenance costs of a pumping station with a forcemain, when capitalized, may offset or be less than  the construction costs of a deep gravity sewer system;
• Learn how when high groundwater, unstable soil, shallow rock, or extremely adverse topography make gravity sewers, pump or ejector stations unsuitable, low pressure systems using grinder pumps with small diameter pressure sewers may be a solution;
• Learn how to calculate the average hourly wastewater flowrate in order to design a sanitary sewer system;
• Learn how to calculate extreme peak wastewater flowrates and how to size a sanitary sewer system to accommodate them;
• Learn how to design for unintended inflow and infiltration in wastewater collection systems;
• Learn about the Manning Formula and how to use it in sewer system design;
• Learn the importance of flow velocity in sewer pipes and velocity guidelines for various flow conditions that may be encountered;
• Find out about basic parameters for sewer pumping station layout; and
• Learn about the different types of sewage pumps and ejectors and when they are used.

Intended Audience

This course is intended for civil engineers and other infrastructure design and construction professionals who want to learn about the basic technology, design guidelines and materials and equipment used in design and construction of wastewater collection and pumping systems for residential, industrial and commercial developments.

Benefit for Attendee

This course will give engineers and others an introduction to the principles and practices of wastewater collection and pumping.

Course Introduction
