Septic System Manual

The ‘Septic System Manual’ was developed by the Urban Infrastructure Service Division (UISD), Department of Engineering Services (DES) under the Ministry of Works and Human Settlement (MoWHS) with technical assistance from SNV as part of the Sustainable Sanitation and Hygiene Programme in small towns.The manual was developed with the objective of providing guidance to authorities at various levels (district and municipal engineers, building inspectors) on technical know-how during the design, construction, operation and maintenance of septic systems. In addition, other communication materials such as leaflets and posters were developed targeting householders/building owners to help understand operation & maintenance of septic systems, including de-sludging of the septic tanks. The septic system manual, leaflet and poster was developed and tested based on learning from the small towns at Chukha Dzongkhag and Thimphu Thromdey.
