Project Experience

The Republic of Palau, Bureau of Public Works, recognized the need to improve its centralized wastewater system in the political and economic center of Koror State.  The Bureau of Public Works was also well aware of various land use proposals and constitutional requirements that might require the relocation of the nation's capitol and other public facilities to the Island of Babeldaop.  These and other system issues prompted the need for an updated wastewater facilities plan for the entire Republic.  Specific plans were developed for each of the 16 states of the Republic of Palau.

James Pedersen, Planning Consultant, participated in onsite investigations of the wastewater system in the State of Koror, as well as the sanitary practices and facilities in each of 15 less developed states.  Wastewater issues were further defined through interviews of state governors and appropriate representatives of various ministries of the Republic. 

Forecasts were developed of anticipated domestic flows for a 25-year planning period.  Future land use trends and population growth were examined to evaluate future requirements for wastewater facility development and management.  Land use data for the Koror system was eventually input as part of a HYDRA computer model that was used to help define future requirements and options for an expanded centralized system. 

Existing and anticipated environmental issues were also evaluated.  For example, incoming fisheries vessels were discharging raw sewage into Malakal Harbor and sensitive lagoon areas.  In the outlying States, some pit latrines discharged into mangrove that were used for subsistence agriculture and nearshore fishery activities.  Management and facility options were identified.
