WHO works in close collaboration with the Institute of Public Health of Japan to strengthen the Operation and Maintenance Network (OMN) of the Water Supply and Sanitation Collaborative Council. During the earlier years of existence of the OMN (initially Operation and Maintenance Working Group), WHO with the support of the OMN membership, prepared some key best practice materials on this important issue, which are available online.
