Bio toilets use bacteria developed by Defence Research & Development Organization to digest the fecal matter and convert it into odourless fertile water, methane and carbon dioxide. The technology is self-sustaining: the anaerobic bacteria will survive and grow without oxygen inside the bio-tank and does not require replenishment.

Benefits of Bio-Toilets

Environment Friendly as it does not pollute land or air.

Improves aesthetics and does not produce any foul smell.

Uses Nature's products to save earth of tonnes of waste.

Water positive solution as no water is wasted on cleaning as in Open Defecation.

Need for sewerage system requiring land and connections is avoided.

Bio tanks are virtually maintenance free.

The bio-gas and reed water can be reused thereby saving energy.

Ground water quality remains uncontaminated.

Space saving: Area occupied by 1 septic tank equals 3 Bio tanks.

Health and Hygiene:

—		Prevents water borne diseases like Viral Gastroenteritis, Typhoid, cholera, jaundice
—		Prevents mosquito borne diseases like Malaria, Chicken Gunia, Dengue etc.

Simple design and easy retro fitment in existing toilets.

Prevents damage to Railway track, keeps platforms free from foul smell and saves money on corrosion repairs.

UNDP has estimated that every dollar spent on water and sanitation generates a return of 8 dollars in reduced health costs and increased productivity.

Installation of Bio Toilets is beneficial virtually under all conditions and circumstances.

WATER

		Water can be used as self sustaining irrigation source

		By adding a reed bed, water can be recycled and used for further purposes.

METHANE

Based on the usage of the bio toilet, the methane produced can be used to generate electricity and for cooking purposes

PROCESS OF DEGRADATION

		The Tank of Bio toilets is a cylindrical/ rectangular structure with the provision of inlet for human waste and out let for Bio gas and water.

		Night soil degradation occurs through microbial reaction which converts it into bio gas and odorless water.

		The gaseous effluent (methane) is either continuously let off to the atmosphere or can be collected to be used for various energy intensive activities like cooking, water and room heating.

		The Water so discharged can be used as liquid fertilizer for horticulture, agriculture or gardening. As this water does not have smell or any harmful content. If we pass this water through reed bed the water can be recycled for flushing.

BIO TOILETS vs PIT TOILETS

FEATURES	BIO TOILETS	SOAK PIT/ LEACH PIT TOILETS
Structure & Functioning	Bio Digester Tank is cylindrical or rectangular in shape and is made of FRP, steel or civil construction and is charged with bacteria inoculums upto 30% of its volume. In any case, it is always leak proof and air tight, so that only treated water comes out of it and nothing comes out without treatment.	Leach Pit/ Soak Pit does not have any external treatment process for digesting the pathogen of human excreta before dischrging the water to the soil. This contaminates the soil and thereby underground drinking water.
How It Works?	Anaerobic Bacteria - digests the human excreta and converts that into odorless and pathogen free fertile water & bio-gas.	Soak Pits have no technology and allows the untreated water to get absorbed in the soil.
Waste Discharge	Useful for Plants and can be used as fertilizer as the same is odourless.	Highly contagious and causes diarrhoea, cholera type diseases and has bad odour.
Usages	Any where, where there is no sever connection and waste required to be disposed off in eco friendly manner, for example, household, exhibition and marriage grounds, market place, place of worship, near the river banks, bus stations and railway platforms, highways, schools, dharmshalas, guest houses, group housing societies and so on.	Remote and public areas installation shall require frequent excavation of collected sludge which may not be possible to manage by state agencies and shall require huge recurring cost, therefore cannot be installed any where.
Space Required & Size of Tank	1/6th of septic tank or soak pit as there is no accumulation of sludge, because the same is constantly being converted to fertile odorless water and methane and the excess water is continously being diposed off.	Septic Tank or Soak Pit are designed in such a manner that it gets filled up within a specified period for specified capacity and then the same is to be desludged which is not a healthy process and involves recurring cost.

ECO-FRIENDLY BIO TOILETS

Anaerobic microbial consortium developed by acclimatization/ enrichment of microbes at low temperature and bio-augmentation with critical group of bacteria.

Fermentation container made of mild steel/ SS/ FRP/ bricks.

The dimensions and internal design varies with number of users, water availability and geo-climatic conditions.

SPECIAL FEATURES

		Choice of material for fabrication/ construction.

		Affordable.

		Organic pollution reduced by 99%.

		Pathogen inactivation by 99%.

		Viability in all geoclimatic conditions prevalent in the country.

		Effluent is free from odour and is safe for environmental discharge.

		Permits toilet cleaning agents.

		Easy to transport and install.

Inspite of government providing 93.5 million toilets during last one decade large number of these toilet still remain unused due to cultural, religious and social reasons and myths prevalent. It only shows that merely providing toilet is not the solution. Lessons will have to be learned from success stories of Bangladesh and other third world countries. Myths on Open Defecation will need to be broken, sanitation behavior will need to be addressed and a demand will have to be generated from the community through education and community awareness programs. Education and communication programs will be launched with the help of other NGOs and willing partners and as a part of Corporate Social Responsibility mission. Some of the proposed such programs are as under:

शौच जीवन का सबसे बड़ा सच

Defecation is the greatest truth of life

हम होंगे कामयाब

We will succeed

जैव शौचालय - देश की ज़रूरत और हमारी इज़्ज़त

Bio Toilet - The country's need and our honor

बापू का सम्मान - ग्राम जागरूकता अभियान

Bapu's honor - Village awareness campaign

जानोगे तभी तो मानोगे - गरिमा के साथ जीवन

Only when you know, you will believe - life with dignity

प्रत्येक घर के लिए जैव शौचालय

Bio Toilet for each home

हमारी गरिमा, हमारा भारत - (पर्यटन, स्वच्छ गंगा, तीर्थ मार्ग)

Our Dignity, Our India - (Tourism, Clean Ganga, Pilgrim Routes)

Suvidha Bio Foundation will undertake:

		Community welfare projects.

		Special projects to build Bio Toilets for women

		Projects for conversion of existing Conventional Toilets into Bio Toilets

		Projects to provide Bio Toilets in rural and urban areas.

		Corporates will be assisted in their Corporate Social Responsibility (CSR) mission programs.

		Projects entrusted by Govt agencies will be executed to achieve the objectives of the Foundation towards a dignified life.

Each program will be monitored and evaluated for impact analysis in accordance with our objectives.
