                       3. Keep the collection system flowing   to the major pump
                       stations, or first by-pass opportunity.


                       4. Repair primary pump stations (the    "An series).


                       S.  once the collection system Is operational, shift
                       ,priority to the repair and operation of the sewage
                       treatment plants emphasizing the following:

                           a. Primary treatment.

                           b. Secondary treatment.

                           c. Tertiary treatment.


                       6.- The effluent reuse system as irrigation and perhaps-
                       the use of secondary effluent for fighting oil flres.


                       7. The odor control system,


                       'THE FOLLOWING IS A DISCUSSION OF OBJECTIVES RELATING TO
                 THE WASTEWATER COLLECTION SYSTEM:

                       It is important to monitor the capability; of the
                 conveyance system based on day-to-day occurrences with respect
                 to repair status and flow capabilities. eg., higher priority
                 items may not be repaired on schedule due to unavailability of
                 repair parts, labor force -problems, line blockage, pipe
                 breakage, or other extenuating circumstances. (This is being
                 done by OXI to some extent.) This will effect the planning and
                 cause realignment of the repair schedule.       First Priority
                 should be given to repairing secondary-pump stations and screw
                 lift stations which do not have gravity by-passes. The second
                 priority should be given to repairing gravity lines (usually
                 by cleaning sand or other obstructions from the pipes or
                 manholes).     These two priorities are of almost equal
                 importance and should be worked simultaneously. if the sewage
 is not flowing down the gravity lines and through the screw
                 lift stations and the minor pump stations, continued blockages
                 will occur.    The pipelines are somewhat self-cleaning if
                 sufficient flow is present.     These are the f irst steps to
                 transporting the sewage away from the living areas which is
                 critical -to public health and odor control in residential
                 areas.
                       OMI analysis of the @re-war d@ography provides some
                 attention to the necessary consideration of population on the
