home owners to keep a record of where water and sewage lines are buried. If the
mobile home park is on post, the preventive medicine activity should also keep these
records, which can be obtained from the post engineers.
b. Sewage Treatment.
(1) If possible, the sewage system of a mobile home park should be
corrected to a public sewage system. If public sewers are not available within a
reasonable distance, adequate treatment facilities must be installed to dispose of the
sewage. Sewage disposal facilities should be approved by the medical authority or
other regulatory agencies before construction. The effluent (outgoing sewage) from
such treatment facilities should be discharged only as permitted by these agencies.
(2) The sewage treatment installation should be located where it will not
create a health hazard or odor nuisance to the occupants of the mobile home park or to
occupants of neighboring property. The geographic layout of the area often dictates the
location of the treatment facilities since gravity drainage of the sewage system is
c. Sewage Systems. Sewage systems must have sufficient capacity to serve
the needs of the community. They must also be economical to construct, operate, and
maintain. The design of sewage treatment facilities for a mobile home should be based
on the maximum number of mobile home lots and the water usage estimated when
designing the water system. The use of garbage grinders and automatic laundry
equipment can significantly increase sewage flow. For this reason, it may be desirable
to determine how extensive the use of these devices will be before designing the
d. Sewage lines. The lines in a sewage system should meet the following basic
(l) All sewer lines should be laid in trenches.
(2) All sewer lines should be separated at least 10 feet horizontally from any
pressurized drinking water supply line.
(3) All sewer connections and manholes should be constructed to prevent
surface water from entering the sanitary sewers.
e. Sewer Service Connections. Each mobile home space should have a
sewer service connection. Figure 4-3 shows a suggested design of a sewer service
connection for a mobile home.
