                 pressure levels should be maintained until the sewer system is
                 reliably operating to the by-pass points.


                      CONCLUSION ig:

                      Gasketx in valves iii the water usage system will have
                 dried and otherwise become impaired -in terms of proper
                 operation.     Many leaks in -household, business* hotel,
                 apartments and elsewhere can be expected to contribute to
                 water demand and resulting sewage flow.

                      RECOMRENDATION ig:

                      The mpw recovery project manager will issue advisories -
                 encouraging the public to have leaking valves and f ixtures
                 repaired for reasons of economy and public benefit. The MPW
                 should also consider issuing an advisory regarding passive
                 water conservation techniques.

                 XBSUR NO.I: DETERIORATED CONDITION OF EXISTING SYSTEM


                      CONCLUS3:ON i 1-

                      There is an obvious and documented need to plan for major
                 rehabilitation of the sewage collection and treatment system.
                 The def inition of major- rehabilitation includes the.
                 replacement of all asbestos-cement (AC) piping in the sewer
                 piping system over a 10 year (?) time frame - 10% a year. The
                 treatment plants (Ardiya especially) should have major
                 additions including expanded capacity and grit removal.

                      RECOMMMMATION il:

                      NPW must begin the process of developing a plan and
                 implementation strategy for critical long term rehabilitation
                 of the sewage collection and treatment systems.


                      CONCLUSION #2:

                      The sewage treatment plants and sewage collection system
         were designed and constructed on the assumption of cheap and
                 plentiful labor. The sewage treatment plants are equipped
                 with manual control valves and gatesi'minimal provision for.
