                      2. Pro-invasion Condition. There are no reported major
                 operational or maintenance conditions which interfere with
                 plant operation to design specifications,, other than extra
                 effort in grit handling.     odors were a problem because of
                 significant recent housing development in the vicinity of the
                 plant.
                      3. Condltion:at the time of Liberation: Significant
                 damage was done to the electrical control system for the
                 tertiary sand.-filter systems and the laboratory and
                 administration building.    it will likely be several months
                 before    the    control   panels    for    the   rapid     sand
                 filter/chlorination system for secondary effluent ran be
                 operated. Laboratory and administration areas can be restored
                 to minimal functional levels much more quickly. It appears
                 that explosives were placed within two control panel cabinets,
                 causing significant damage to the adjacent panels also. These
                 controls are essential to the operation of the rapid sand
                 filters because of the complexity of the required operational
                 sequencing of various.pumps and other equipment (including air
                 injection on the back wash cycle).      Damage to controls for
                 the plant ef fluent pumps is restricting operational capability
                 for the reuse system.

                      4. Present Condition and Recommendations: Very little,
                 if any, work has been accomplished. Restart of this plant is
                 a lower priority than the repair of the collection system and
                 the restart of the Ardiya Plant. The plant is operational and
                 could provide primary treatment almost immediately, if a bit
 in flow control within the plant.
                 Aeration basins could be operated for two purposes of
                 achieving two goals: grit removal prior to primary treatment
                 in the clarifiers; and in a normal aeration iftode for building
                 up mixed liquor suspended solids in the aeration basins (using
                 some clarifiers and recirculation to accomplish the latter).
                 Please see recommendations made in paragraph c. concerning
                 start-up of 'the Jahra Plant. The same recommendations are
                 valid for the Rikka Plant.
                      General plant preventative maintenance and upkeep was
                 halted -during the occupation and has not yet restarted. We
                 ;anticipate that minor start-up -mechanical and electrical
                 problems will occur due the lack proper maintenance during
                 this period. General mechanical and electrical checks of all
                 equipment is required.
