It sought to promote and develop sewerage infrastructure in urban areas beyond Metro Manilla. Under this program, the central government introduced an implementation support system where 40% of total development costs for sewerage infrastructure of local government units (LGUs) would be subsidized by the national government, subject to standard appraisal procedures headed by the Department of Public Works and Highways (DPWH). The said 40% subsidy cover was eventually increased to 50% with the intent to attract more interested LGUs to apply for the support facility.. However, as of February 2019, only one local government unit has officially applied for the NSSMP support facility (Zamboanga City. In order to remedy this situation, the DPWH established a policy of striving to increase the application of this system through the expansion of local governments receiving the subsidy by means of infrastructure development. Instead of restricting the subsidy facility only to highly urbanized cities (HUCs), the facility was also made available to component cities (cities not regarded as highly urbanized) as well as first class municipalities. One of the reasons that sewerage infrastructure development has not progressed at the same pace as what the Philippines requires is due to the limited basic infrastructure in urban localities outside Metro Manila. However, the government of the Philippines is aware that delays in the provision of sewerage services would not only lead to environmental degradation, but also have an adverse impact on the tourism industry as well as agriculture, forestry, fisheries and other such industries. Improving sewerage and septage conditions in the Philippines was manifested in the much publicized closure of the popular resort island of Boracay in April 2018 by no less than President Rodrigo Duterte at a cabinet meeting. The president at that time decided to close down the island due to utter failures in sewerage management in the locality and due to sewerage management violations of several establishments in the island. Furthermore, announcements that effluent standards were not being upheld in 82 of 351 resort hotels in Bohol (another similar
