1-1. Purpose and Scope
This manual provides guidance for the design and layout
of civil works pumping stations used for removal of
interior drainage from areas protected by local flood
protection works and for water supply. The discussion
presented in this manual is general in nature. The devel-
opment of detailed design criteria is presented in other
manuals referenced herein. This manual is for the guid-
ance of Corps of Engineers personnel engaged in the
design of flood protection projects.

Plates 1 through 12 in Appendix A show different types
of pumping stations constructed by the Corps of Engi-
neers. A short description of each pumping station is also
provided.
1-2. Applicability
1-5. General
This manual applies to all HQUSACE elements, major
subordinate commands, districts, laboratories, and field
operating activities having civil works responsibilities.
a. Dependability
. Pumping stations are one of the
more vulnerable features of a flood protection project.
The failure of a pumping station during a flood could
result in considerable damage within the protected area.
This would cause the loss of some or all of the benefits
that justified construction of the project. Consequently,
station dependability must be the primary consideration,
during the design and pump selection process.

b. Economics
. While the cost of the pumping sta-
tion is generally but a small percentage of the cost of the
entire project, this does not mean that the designer is to
proceed without any consideration of cost. Because of the
infrequent operation of the majority of local flood protec-
tion pumping stations, efficiency can be sacrificed to a
certain extent in favor of equipment with a lower first
cost. However, higher pump efficiencies can actually
lower the installed horsepower requirements and reduce
operating costs for large stations that have frequent usage.
The extra costs to provide higher efficiency equipment
should be studied on a life cycle cost basis over the proj-
ect life. This economic study should consider both first
cost and the cost of operation, maintenance, and replace-
ment of equipment over the project life.

c. Refinements
. The equipment selected must be
rugged, reliable, and well suited for the required type of
service. The pumping station structure should be sized to
house and support the equipment. Refinements which
make no realistic contribution to usability or dependability

should be strictly avoided. Architectural appearance will
not be a governing criterion except in highly developed
areas where concessions in regard to exterior treatment
may be made as discussed in EM 1110-2-3104.
accordance with ER 1165-2-131. Engineers responsible
for the preliminary design and layout of the pumping
facility should coordinate any special design features that
may affect the local sponsor’s costs with the project
manager.
d. Large stations
. In the design of some stations an
unusual combination of conditions may be encountered
which will require special treatment. This will frequently
be the case for exceptionally large stations. However, the
fundamental principles, criteria, and policies provided
herein are applicable to all stations. Stations having a
capacity of 30 cu m/sec (1,060 cu ft/sec) or larger will be
engineered by the Hydroelectric Design Center (HDC) in
accordance with ER 1110-2-109.
b. Maintenance and operation
. A project’s Opera-
tion and maintenance manual will outline the responsibil-
ities of the project sponsor for the operation, maintenance,
repair, replacement, and rehabilitaion (OMRR&R) of all
project features. Instructions for the preparation of opera-
tion and maintenance manuals are provided in ER 1110-2-
401. Development of the pumping station feature of the
manual is contained in EM 1110-2-3105.
