UNU-IAS Water and Urban Initiative Reveals Its Findings on Manila’s Water Environment

Manila, Phillipines



On 2 and 3 March 2017, a consultation workshop, organized by the UNU-IAS Water and Urban Initiative (WUI) and the University of the Philippines-Diliman School of Urban and Regional Planning, was held in Quezon City. It brought together various stakeholders and researchers on flood control, sanitation and wastewater, water quality of urban rivers, and water-borne health risks.

The first day of the workshop was attended by researchers from various universities such as UP Diliman, UP Manila and De la Salle University, as well as experts working on various environmental projects, including the Synergistic Capacity Advancement For The Management of Laguna Lake (SCALE), the Disaster Risk and Exposure Assessment for Mitigation (DREAM), the Nationwide Operational Assessment of Hazards (NOAH), and Philippine Light Detection and Ranging (PHiL-LiDAR) to discuss WUI preliminary findings as well as model refinement.

The second day was attended by practitioners and experts from the Department of Public Works and Highways (DPWH), Department of Health (DOH), Department of Environment and Natural Resources (DENR), Metropolitan Manila Development Authority (MMDA), Pasig River Rehabilitation Commission (PRRC), Metropolitan Waterworks and Sewerage System (MWSS), Manila Water, Maynilad, Local Water Utilities Administration (LWUA), the Asian Development Bank (ADB), and other selected local government units in metro Manila.

The DPWH Undersecretary for Planning and Private-Public Partnerships, Catalina E. Cabral, talked about the Department’s ongoing and future interventions for flood prevention in the metropolitan area. Engineer Gerardo R. Sullano, meanwhile, discussed the existing, on-going and planned MWSS interventions for sewerage and sanitation.

Throughout the event, WUI researchers collaborated with local experts to gather more updated data and likely incorporate it into WUI’s simulation models. These may include PHiL-LiDar’s high-resolution maps and Maynilad and Manila Water’s 2015 water quality data.

Towards the end of 2017, another workshop, including a training component, will be held to disseminate the refined models.
