Conventional piped sewerage with lagoon treatment has been installed in the core areas of Thimphu with coverage of about 70%. However, the urban sanitation issues that have been flagged for action are: to ensure provision of flush toilets or latrines with proper septic tanks and soak pits in all new houses; dismantling VIP latrines and long drop toilets; to provide piped sewerage and wastewater treatment plants in all urban areas, allocation of funds for piped sewerage and treatment plant and awareness campaign on basic sanitation.
