Water supply and sanitation

Water supply and sanitation outside Metro Manila is provided by the government through local water districts in cities or towns. Metro Manila is served by Manila Water and Maynilad Water Services. Except for shallow wells for domestic use, groundwater users are required to obtain a permit from the National Water Resources Board. In 2022, the total water withdrawals increased to 91 billion cubic meters (3.2 × 10 cu ft) from 89 billion cubic meters (3.1 × 10 cu ft) in 2021 and the total expenditures on water were amounted to ₱ 144.81 billion.

Most sewage in the Philippines flows into septic tanks. In 2015, the Joint Monitoring Programme for Water Supply and Sanitation noted that 74 percent of the Philippine population had access to improved sanitation and "good progress" had been made between 1990 and 2015. Ninety-six percent of Filipino households had an improved source of drinking water and 92 percent of households had sanitary toilet facilities as of 2016; connections of toilet facilities to appropriate sewerage systems remain largely insufficient, however, especially in rural and urban poor communities.
