Project Requirement

The Samoa National Water Resources Management Plan (2021-2030) is a strategic multi-agency plan to ensure the current and future availability of freshwater resources for public and private use. The development use of the Samoa NWRMP is a legal requirement under the Samoa Water Resources Management Act (SWRM Act, 2008) as well as a national necessity given the twin challenges of economic growth and climate change vulnerability. The Terms of Reference specifically required:

  • a review of the 1996 National Water Resources Master Plan Study to assess progress, remaining gaps and current limitations given the passing of 25 years;
  • a review of current WRD monitoring and analytical capacity; and
  • the delivery of the NWRMP as largely defined in the WRM Act – focusing on water resources availability, water demands, and strategies for minimising water supply shortages.
