The Code on Sanitation of the Philippines was promulgated by President Ferdinand E. Marcos in 1975 with the objective of directing public health services towards protecting and promoting the health of Filipinos. It was developed with contributions from various government agencies and organizations, and codified existing health laws and regulations. The Code assigns functions to the Department of Health such as promoting public health, extending health services, developing health programs, and regulating hospitals and clinics. It also establishes standards for drinking water quality, treatment, and testing.
