NBC 208 : Sanitary And Plumbing Design Requirements has been prepared having considered the provisions of Water Resources Act 2049. It contains general guidelines for water supply installations, sewage/ waste water disposal installations and rainwater disposal installations in buildings. The objectives are to make adequate water supply available (without any interruption ) for the purpose of drinking, bathing, flushing toilets and any domestic use including fire fighting; to provide a system of self cleansing conditions for conveyance of foul waste water and for the removal of such waste water/sewage to a sewer or outer outlet without risk of nuisance and hazard to health and to dispose rainwater in buildings. Due to the limited technical manpower in the country's construction industry, the code has been simplified for the ease of use and implementation. It is hoped that with the development of the manpower and modernization of construction processess, it will be possible to release more sophisticated set of sanitary installation guidelines in future.
