This Integrated Water Resources Management (IWRM) National Water and Sanitation Sector Plan was developed by the Cabinet-appointed National Intersectoral Water Coordination Committee (NIWCC) which reports through Minister of Mines, Energy and Rural Electrification to Cabinet of the Government of Solomon Islands (GoSI).

Its development was supported by the Secretariat of Pacific Countries (SPC) Applied Geoscience Division (SOPAC) under the Pacific IWRM National Planning Programme in a process facilitated by Professor Ian White of the Australian National University. Development of the plan was based on the principles of integrated water resource management in island counties, water use efficiency and adaptation to climate change.
