Construction of Toilet

SEVAI thought about sanitation:

  • Sanitation is more important than political independence
  • Religion and Sanitation
  • A lavatory must be as clean as a drawing room
  • Perfect sanitation makes an ideal village
  • Sanitation for minister and Menials alike.

Similarly SEVAI is also implementing not only sanitation program to cover all the category of people in the project areas but also conducting Health and Hygiene Training within the Village.

About the Project

"Perfect sanitation makes an ideal village".   Since Independence the government of India has been planning to initiate Health and Sanitation. In tune with his initiative the central government has implemented the Swachh Bharath Mission (SBM) in October, 2014. The SBM has made up to achieve Open Defecation Free (ODF) villages all over the country.   The SBM momentum has been continued to cover up in every nook and corner of the villages.

The Honorable Chief Minister vision of Tamil Nadu 2023 aims at providing the best infrastructure services in terms of universal access to water and sanitation. The goal of an open defecation free Tamil Nadu needs to be achieved through multi-pronged strategy by organizing all stakeholders into a mass movement to root out the practice of open defecation.

Clean India is one of the dream of Mahatma Gandhi, but this dream is unfulfilled, this programs is launched to give tribute to Gandhiji and fulfil his dream - Narendra Modi.


The size of the Individual House Hold Toilet is 4.8' length x 4.8' breadth x 6.5' height with pre-cast cement roof and Cooling sheet facilities of 50mm thickness with doors and ventilation.

  • To accelerate sanitation coverage in rural areas in order to achieve the goal of open defecation free Tamil Nadu in a time bound manner.
  • To actively involve the various stakeholders such as Panchayat Raj Institution representatives, Self Help Groups, Panchayat Level Federation (PLF), field functionaries of various Government departments, etc., in the eradication of open defecation.
  • To sustain the practice of safe sanitation through continuous Behavioral Change activities.

The Individual House Hold Latrines (IHHLs)   are to be constructed with twin-leach pit models with   using the cement concrete rings inside the leach-pit as lining. These pits can also be constructed with locally available rough stones   for lining the pits so that the pit will work for longer period and serve as leach-pits for disposal of human excreta and waste water flushed from the toilet pan. The circular pits with 3 feet dia and 3 – 5 feet depth below the ground-level lined with 1.5 Crusher serves a family size of 5 – 7 members for a period of 7 – 10 years depending upon the soil strata and permeability conditions.These twin pits could be alternatively used for a period of 14 years on an average and when one pit is filled and closed for one year period, the human excreta will become totally composted ones like humus which could be used as manure for kitchen garden and in the fields as the humus content would be harmful to handle at the same time serve as the nutrient for the soil.

The toilet models we promote should be acceptable to the people socially, culturally, economically and environmentally.


SEVAI constructed 300 Individual Household Toilets. Around 1540 pupils are benefited through this project. This IHHL project has practically achieved behavioural change among target beneficiaries with adequate hygiene practice among the members of the families. As per the statement of Prime Minister, the dream of Mahatma Gandhi has been achieved.
