Sanitary and Industrial Wastewater Collection -
Pumping Systems
Vincent Reynolds, P.E.
Overview
Wastewater is a part of everyday life. Every
living creature and every industry on earth creates waste in some form or
another. Wastewater acts as a medium to direct waste to various treatment plants
by means of sanitary sewer lines.
Oftentimes topography and
economics does not allow sewer lines to flow by gravity. In those cases a
pumping system will be required. This 4 hour course is part II of a two part
series. This course will focus on
sewer lines where wastewater flow is facilitated by the use of pumps. Part
I focuses on sanitary sewer lines that are under gravity flow.
This course will provide information that will
guide the engineer in planning, designing and constructing sanitary sewer
systems. The course
materials are based solely on the materials “Sanitary and Industrial Wastewater
Collection (Pumping Systems)" as published by the Army Corps of Engineers.
Several formulas will be presented to instruct the student how to engineer
sanitary wastewater pumping systems. Several popular equations such as
Hazen-Williams and the efficiency equation will be presented.
The student must take a
multiple-choice quiz consisting of twenty (20) questions at the end of this course to earn PDH credits.
