Priority Collaborative Actions to the United Nations System-wide Strategy for Water and Sanitation

The Priority Collaborative Actions (PCAs) are high-impact activities that will be undertaken by the United Nations system to accelerate progress on water and sanitation.

Structured around six priority areas, the PCAs guide a more integrated, solution-orientated approach. Led by United Nations entities, the PCAs are designed to support countries to speed up their efforts towards national plans and priorities, and internationally agreed goals and targets on water and sanitation.

The PCAs directly support the implementation of the Collaborative Implementation Plan (CIP) 2025–2028, serving as a key mechanism to operationalize the United Nations System-wide Strategy for Water and Sanitation.
