under para. 2.2.8. Water supply in sufficient quantity and of a quality
meeting current Safe Drinking Water Act (SDWA) standards should be provided.
This service should meet the base's continuing needs based on the requirements
of the station's personnel and equipment, plus that necessary for fire
protection and for other purposes, such as flushing and irrigation.
Restoration of normal flow-operating procedures as applied to clarifiers and
filters must be determined separately for each station.
Sewage Inactivation
2.5.7
General. Approval for changes in the wastewater system layout or
2.5.7.1
operation that will alter the degree of treatment or final disposal point must
be obtained from appropriate regulatory agencies. Normally, this will require
a modification or reissue of the discharge permit. In some cases,
installation of septic tanks and leaching fields for servicing small
contingents of guard or maintenance personnel may be more advantageous than
operating the station treatment facility.
Continuance of Sewage Treatment. When sewage treatment is
a)
continued in the station facility, flow should be concentrated
into the least number of units consistent with the maximum
loadings permitted. Units removed from operation should be
drained, cleaned, thoroughly oiled, and filled with clean
water. Recirculation may be employed to eliminate excessive
detention periods and resultant septic action. In the absence
of recirculation facilities, surplus pumps and temporary lines
should be utilized to effect recirculation. Treatment plant
equipment should be operated normally, and the following
procedures observed:
(1)
Safeguard filter-dosing tanks against freezing by reducing
dosing tank capacity or by concentrating the flow to one
filter during cold weather.
(2)
Drain siphons and exposed pipelines or otherwise protect
against freezing.
Lift station discharge pipe contents should be displaced
(3)
at least once every 6 hours; it may be necessary to use
fresh water to accomplish this, but cross-connections
should be avoided.
(4)
Float controls in wet wells should be adjusted to maintain
sewage at a level that will ensure frequent pumping.
(5)
Pumps, standby engines, and control apparatus should be
inspected and operated at least once each week.
