In 1996 CSV with assistance from UNICEF established a sanitation park to enable first time users to have a better understanding of the choices, maintenance requirement and costs involved. The park has been replicated in other states through government funds In Maharashtra, Himachal. Currently CSV is the Key resource agency for training on water and sanitation. We have experience not only in construction of various types of individual toilets but have used our technical expertise in community toilets for generating bio gas and electricity as per requirement. These units have been provided at following locations

  1. Our campus at Kumarappapuram;
  2. Ecotech Village, Boldawadi, District Hingoli, Maharashtra;
  3. Antarbharati Ashram, Dabha, Nagpur, Maharashtra;
  4. National Institute of Rural Development, (NIRD), Hyderabad;
  5. Andhra Pradesh Academy of Rural Development (APARD), Hyderabad.

CSV has carried out R & D for recycling spill water (Near Hand Pump and wells); Handling and treating Grey water at its source (Soak Pit); Using Animal waste (Dung and Urine) in scientific way (Bio gas and Composting); Managing Agro waste (Composting and Bio Residue Stove for generating heat energy) etc.

We have also assisted in creating a clean environment by using market waste for generation of energy. CSV has been involved in providing technical guidance to districts and the village which have won the first prize for the “SANT GADGE BABA GRAM SWACCHATA PURASKAR”, instituted by Maharashtra Government (Department of Drinking Water and Sanitation).

Women's empowerment has been our priority and we not only have provided technical expertise for construction but also trained women and men for construction activities (through Mason Training), so that these structures can be replicated at the local level.

CSV in collaboration with TATA has developed and popularized "Arogya Water Filter", which are very efficient and can be fabricated at village level using local resources like Ash of Rice husk, Sand, Pebble, nominal amount of Cement. These filters can be fabricated by trained members of SHGs.

CSV is a technology generating and technology transferring institute. In the field of total sanitation CSV has done extensive work. It includes generation of technology and methodology. CSV has developed a series of technologies in the field of solid and liquid waste management in the rural, peri-urban and urban areas. These interventions are enlisted below

  1. Leach Pit Toilet with complete super structures
  2. Spill water recycling Unit
  3. Biogas (Deen Bandhu and Balaji) to handle animal waste
  4. NADEP Tank for making manure from agro waste
  5. Four Pit Vermi Compost tank for recycling organic waste with the help of worms.
  6. Soak pit for handling sludge or brown water
  7. Aangan wadi Toilets for Kindergarten Students.


Leach Pit Toilet:

CSV has evolved “Wardha Model” of toilet which requires minimum amount of water to clean a pan and the person. This is feasible because of following features which are embedded in every toilet constructed by CSV

  1. Pan has greater slop (45 Degree)
  2. ferrocement latrineThere is no water seal in “Wardha Model” toilets because even the smallest water seal is of 15 mm and to clean it about 10 litres of water is required. Thus to save water we have introduced flap seal. Because of introduction of flap seal smell and flies do not enter the toilet. The gas generated in the pit escapes from the vent pipe.
  3. From the pan night soil moves directly in the leach pit. This feature saves lot of water.
  4. From the leach pit water moves in the adjoining soil and night soil decomposes in to nutrient rich manure.
  5. The pathogenic microbes present in the night soil are not able to moves more than one meter distance hence all the water bodies (Open well, tube well etc.), located 5 meters away from the toilet give safe drinking water.


Policy Intervention

  1. Leach Pit Technology has been accepted by CAPART, An autonomous Body of Ministry of Rural Development, Government of India
  2. The design of toilet has been approved by UNICEF, Mumbai
  3. The model is being replicated extensively by Ministry of Rural development, Government of Maharashtra.
