MEMBERS of urban poor and militant groups on Tuesday marched to the Metropolitan Waterworks and Sewerage Systems (MWSS) head office to demand the full refund of some P15 billion in added charges that were illegally passed on to consumers.

Anthony Barnedo, secretary-general of the Kongreso ng Pagkakaisa ng Maralita ng Lungsod (KPML), particularly demanded that the MWSS compel water concessionaires Maynilad Water Services and Manila Water Company to return the extra charges to consumers.
