Fecal sludge management:
Fecal sludge management (FSM) (or faecal sludge management in British English) is the collection, transport, and treatment of fecal sludge from pit latrines, septic tanks or other onsite sanitation systems. Fecal sludge is a mixture of human excreta, water and solid wastes (e.g. toilet paper or other anal cleansing materials, menstrual hygiene materials) that are disposed in pits, tanks or vaults of onsite sanitation systems. Fecal sludge that is removed from septic tanks is called septage.
FSM is necessary in densely populated areas where a proportion of population is not connected to a sewerage network, and the covering and rebuilding pit latrines is not possible. This is the case in most urban areas of developing countries, but such services are also used in developed countries where sewerage systems are unavailable.
Using smart systems this technique can be applied Nationwide.
