MWSS participates in the 2015 World Water Day Celebration Fun Run held on 22 March when it sent a contingent of some 60 MWSS employees in the Run. Aptly dubbed Run for Water and Sustainable Development, the Run was organized by Maynilad and covers the stretch from the Cultural Center of the Philippines up to varying portions in Roxas Boulevard from Kalaw to Libertad streets depending on the required distance (i.e., 21k, 10k, 5k, 3k, 1k). It was one of the culminating events for the 2015 World Water Day Celebration that lasted from March 16 to 26 of 2015. The 2015 WWD celebration which has a theme of Water and Sustainable Development was made up of various worthwhile activities and organized and participated in by both government and non-government agencies involved with the water industry. Lead agency was the Department of Environment and Natural Resources (DENR).
