United Nations Water (UN-Water) is an interagency mechanism that coordinates the efforts of United Nations entities and international organizations working on water and sanitation issues. "Over 30 UN organizations carry out water and sanitation programmes, reflecting the fact that water issues run through all of the UN's main focus areas. UN-Water's role is to coordinate so that the UN family 'delivers as one' in response to water related challenges." The majority of the offices is located in Geneva, Switzerland.
