Nonthaburi City Municipality is the principal city of Nonthaburi province, located to the north of Bangkok. It has a registered population of 256,457 in the area of 38.9 km2 (NCM 2015a). Most of the houses have onsite sanitation systems such as septic tanks or cesspools. The city municipality is responsible for the collection, transportation and treatment of the generated faecal sludge according with the Public Health Act 1992; resulting in 79% of excreta flow safely managed.
