Project Experience

Location: Islands of Tutuila, Aunuu, Ofu, Olosega, and Tau
Client: American Samoa Power Authority
P.O. Box PPB, Pago Pago, American Samoa 96799
Contact: Mr. Mike Dworsky, P.E, Manager, Wastewater Division
Year Completed: 1995 and updated 2003
Project Scope:

The American Samoa Power Authority (ASPA), a quasi-public utility agency, is responsible for the management, operation, and maintenance of American Samoa’s water, wastewater, power and solid waste systems.  ASPA’s approach to utility management approach is well-recognized in the Pacific Basin; it is regularly consulted by other utilities in the region for solutions to system management and day-to-day operations.

ASPA retained Pedersen Planning Consultants (PPC) to assist this regional utility with an update to its earlier Utilities Master Plan that PPC and Hart Pacific Engineering prepared in 1995.  The update initially included PPC’s re-evaluation of regional population, land use, and economic trends in American Samoa.  Earlier detailed forecasts of population and land use were modified for 72 villages and smaller communities. 

Using a statistical model developed by PPC, population and land use forecasts were subsequently applied to water consumption and domestic wastewater generation rates to determine anticipated average daily consumption and wastewater generation for five time increments over a 20-year planning period.  The determination of water consumption rates involved a detailed review and aggregation of water meter record data, as well as a correlation of preliminary consumption rates with other Pacific Island communities.  It also included an assessment of the potential opportunities associated with water conservation and the calculation of potential water savings.

The second task of the project involved an evaluation of selected public health and environmental issues, e.g., groundwater and nearshore marine water quality.  Particular attention was given to more recent changes in the U.S. Clean Water Act and related regulations of the U.S. Environmental Protection Agency.  These changes were evaluated in the context of implications to future utility management.  

The Utilities Master Plan update gave greater attention to future water and wastewater system manage-ment and related water resource management.  PPC evaluated the existing rate structure and made recommendations concerning the approach to the adjustment of future water and wastewater rates.  Recommendations concerning future information management were provided in light of available technologies associated with geographical information systems, maintenance management, and inventory control.

Water resource management recommendations addressed the sustainability of future water production.  General criteria and standards were recommended for future groundwater exploration and well development.  New recommendations were also provided for the establishment of a water conservation program on the Island of Tutuila.

A new aspect of the Utilities Master Plan involved the recommendation of a process for future system planning for the ASPA Water and Wastewater Divisions.  System planning recommendations identified the need for both medium-term and annual system plans.  A recommended planning process identified the scope of annual and short-term planning efforts, specific responsibilities for each aspect of system planning, and related coordination within the utility.
