On 13 October 2020, the MWSS Regulatory Office (RO) participated in the International Water Association (IWA) public webinar on the topic: Regulating for Citywide Inclusive Sanitation (CWIS). The CWIS is a public service approach to planning and implementing urban sanitation systems for achieving the outcomes summarized in the United Nations Sustainable Development Goal 6 (SDG 6)—safe, adequate, equitable, and sustainable sanitation for all in urban areas regardless of the location and technologies available in delivering the service.During the knowledge sharing activity, MWSS RO Chief Regulator Atty. Patrick Lester N. Ty and CWIS Advisory Board and Task Force Members from Latin America, Africa, and Asia discussed the role of regulators in broadening access to quality sanitation services; and exchanged experiences, challenges, strategies, and best practices in regulating CWIS.Chief Regulator Ty emphasized the expansion and improvement of sanitation and sewerage services within the Concession Area as vital in the agency’s mission to achieve CWIS and protect not only the environment but the health and well being of its consumers. He further emphasized that it is through cooperation among all stakeholders that quality sewerage and sanitation services may be made available, accessible, affordable, and sustainable for all.
