GENERAL
1-1. Purpose and scope.
This manual, intended for planners and design engineers,
presents information on water quality standards
and design criteria for water treatment processes.
This manual also establishes criteria to be followed in
determining the necessity for and the extent of treatment,
and on procedures applicable to the planning of
water treatment projects. This manual is applicable to
all elements of the Army and Air Force responsible for
the planning and design of military construction,
1-2. Water treatment proiects.
State health department, State water resource, and
U.S. Environmental Protection Agency personnel, as
appropriate, should be consulted in the early stages of
project planning regarding supply sources and associated
water treatment needs. In addition to the usual
treatment that may be required to insure delivery of
potable water, consideration will be given to the need
for special treatment to protect pipelines, water heat,-
ers, plumbing fixtures, and other equipment against
scaling, corrosion, and staining, Because of the widely
varying conditions and the many types of water, it is
not possible to establish criteria for all cases of special
water treatment. Treatment for prevention of scaling
and corrosion may not be entirely effective; and in
many cases a decision as to the necessity of special
treatment cannot be reached prior to actual operating
experiences. In general, special treatment will be provided
only in cases where a study of water analyses
and experience with the water definitely show that
there will be severe corrosion of the water system or
that severe scaling of hot-water heaters, storage tanks,
and other parts of the plumbing system will occur.
Marginal cases will be deferred and treatment provided
only after operating experience determines
treatment to be necessary.
1-3. Water quality criteria and standards.
Information on current criteria and standards for raw
and potable water are presented in appendix A.
