This treatment plant is designed by BORDA and CDD Society and executed by MCLand Blue Water Company, a sanitation providing services company that is providing end-to-end Faecal Sludge Management Services to improve sanitation, health and the environment in Leh and serve as a model to other towns. As most of the septic tanks are poorly designed and the underground water table is high (only 30 feet in some places), in 2017 there was early evidence of water contamination, possibly due to overflowing septic tanks. Borewells are extensively used for drinking water, therefore water pollution can have serious health and economic consequences. Therefore, the Municipal Committee of Leh (MCL) ordered that septic tanks are to be made water tight and mandatorily desludged every year. The town needed a FSTP to safely treat and reuse the sludge. The FSTP must handle both the challenges of high altitude and extreme climatic conditions, as well as highly variable sludge inflow as activities will be minimal in the winter.
