Why Sulabh Sauchalaya ?
  Septic Tank System     Sulabh Shauchalaya System
(1)
It costs around Rs. 30000-35000 for its construction for an average size family. So its not affordable for a family with ordinary income.
  (1)
It costs around Rs. 8000-10000 for constructing the same size toilet. So, for a developing country like India , this is the best system.
       
(2)
Its tank is closed from all the sides. There is a vent pipe to take the biogas, produced by stool, out of the tank. This gas causes pollution and bad odour in the air .
(2)
The floor of the pit is raw so gas is automatically absorbed in the soil. The pit is covered with RCC cover so there is no requirement of gas exit pipe. It helps in preventing air pollution and bad odour.
       
(3)
Its pan and water seal is structured in such a manner that it requires excess water for the decixing of stool. At the same time , tank functions in such a way that it requires atleast 10-12 litres water to dispose stool. Due to this it requires the facility of Flush Cistern in turn causes extra expenses & extra water as well.
(3)
 Under this system, Pan and water seal is specially designed which is slant. So for the decying of stool it requires just 2-3 litres of water. Since pits dont require extra water so flush cistern is not needed causing less expenditure and less need of water.
       
(4)
Its tank functions in such a way that the stool settles down to the surface of the tank. After some time when the tank is full of stool, it needs to get cleaned. It requires sweepers to do so. So through this system , the inhuman behaviour with sweepers can't be eliminated.
(4)
Under this system, there are two pits. Serially when one pit is full then stool is passed in the second pit and first one is left for drying. After some time stool takes the form of fertilizers which is odour free and harmless. It can be taken out by the user itself. So one doesn't need to ask for sweepers. Thus the "Bhangi Mukti Abhiyan" is carried on.
       
(5)
Regular cleaning of tank causes dirty water and stool to be exposed to the environment. It increases the chance of spreading diseases & infections through flies. Moreover no fertilizers are produced.
(5)
The fertilizers taken out of pits dont cause any disease. Rather it is used in gardening for the development of vegetables, fruits, flowers etc. which are good for health.
       
(6)
Under this system, tank needs to be big which requires more space.
(6)
Comparatively the size of the pits are smaller. So it can be made in a smaller space.
       
(7)
 The ratio of length & breadth should be equal of the tank while constructing the toilet. So it basically needs a particular plot space.
(7)
The ratio of length & breadth of the pits can be changed accordingly as per the available space. So it can be built anywhere.
       
(8)
Trained supervisors and "rajmistri" are required to construct this system.
(8)
The construction process in this system is so simple that it doesn't require any extra training to the rajmistri or supervisors.
       
(9)
Tank always spreads bad odour gas through vent pipes and problem of its cleaning causes this tank to be constructed outside the home.
(9)
Neither the pits spread bad odour nor there is dirtyness while cleaning. So it can be made inside or outside the house.
       
(10)
In a cold place where there are chances of freezing, there is always a possibility of blasting of the tank as tank always remains full and exposed to the environment.
(10)
There is least chance of bursting due to freezing in the pit because its not full completely. Also water goes out through pores and raw floor in case of increase of pressure. Moreover it has no direct contact with atmosphere.
