Project Experience

Project: AMERICAN SAMOA WATER FACILITIES PLAN
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, USEPA Construction Grants Manager
Year Completed: 2001
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.  In order to secure U.S. funds for various water system improvements, the ASPA Water Division is required to periodically prepare a water facilities plan for the U.S. Environmental Protection Agency (USEPA), Region 9.  In view of PPC’s extensive experience in American Samoa, PPC was retained to prepare a water facilities plan for the 2001-2015 period.

The proposed water facilities plan program included 14 water system projects.  New transmission line, water storage, and distribution system projects were identified for the extension of the primary water system to several villages relying on surface water systems for their potable water supply.  The development of new satellite water systems was recommended for the remote village of Afono since connection to the primary system was not feasible.  Proposed groundwater well development projects were also identified for the Island of Tau where salt-water intrusion had impacted the quality of existing groundwater well supplies.  System management projects reflected ASPA’s desire:

  • to perform periodic hydraulic modeling of its primary water system.

  • the application of SCADA systems to monitor wells, storage tanks, and transmission systems.

  • to establish operation and maintenance program for new water treatment plants.

The plan evaluates natural resources, resident population trends, and relevant economic trends.   Primary drinking water issues that were examined by PPC included the growth in water demands on the Island of Tutuila, sustainable production yields from Tutuila’s basal aquifer, the hydraulic capacity of the primary water system, the growing concentration of land uses in the Tualauta County, the impact of soil-based wastewater treatment upon groundwater resources, insufficient water consumption revenues to support future O/M and capital costs, and governmental regulations impacting the cost of Water Division operations.
