The old man was well ahead of his time in more ways than one! He had installed dry sanitation systems in his hermitage. He was an advocate of sanitation systems that do not use copious quantities of water to transport pee and poo. None of the old man’s disciples who formed government truly understood his maverick ideas…be it on sanitation or on education! Anyway, we will speak on the old man’s ideas on education elsewhere. Regarding sanitation, let us read one of the pieces that the old man wrote on 13th September 1925, which appeared under the title ‘Our Dirty Ways’ in Navajivan
- Both excretory functions should be performed only at fixed places.
- To pass urine anywhere in a street, at any place not meant for the purpose should be regarded an offence.
- After passing urine at any selected place, one should cover up the spot well with dry earth.
- Lavatories should be kept very clean. Even the part through which the water flows should be kept clean. Our lavatories bring our civilization into discredit; they violate the rules of hygiene.
- All the night-soil should be removed to fields.
“. . . If my suggestion is followed, no one would need to remove night-soil, the air would not become polluted and villages would remain very clean.”
Cut to 1947!
Probably the most damaging non-indigenous concept that we adopted unthinkingly is one of water-based sanitation systems. Both versions of “drop and store” and “flush and forget” sanitation systems have caused irreparable damage. Improper disposal of feces and wastewater has led to pollution of our waterbodies. Pathogens from the waste pollute our water and food and eventually pollute our own bodies. When 80% of the diseases in India are a result of improper sanitation, much more than one’s own health is affected. Specifically, 73 million working days are lost annually due to sicknesses caused by unsafe water and lack of sanitation. The economy of India as a whole is impacted since people must pay for visits to the health centre and on occasion lose their jobs because of an inability to go to work.
So, is there a magic wand? The old man, we all know we are talking about MKG, would have wanted each one of us to use the magic wand! Had he lived few more years, the next contest he would have announced would have been on a toilet system. But of course, for the old man liberty meant universal responsibility!
If you are a bit tired by now and are looking for some semblance of a technology solution, the good news is many attempts have been made and continue to be made to develop sustainable sanitation systems. The main objective of a sustainable sanitation system would be to protect and promote human health by providing a clean environment and breaking the cycle of disease. In order to be sustainable, a sanitation system has to not only be economically viable, socially acceptable, technically and institutionally appropriate, it should also protect the environment and conserve natural resources.
Here are some sustainability criteria:
- Health and Hygiene:includes the risk of exposure to pathogens and hazardous substances that could affect public health at all points of the sanitation system from the toilet via the collection and treatment system to the point of reuse or disposal and downstream populations. This topic also covers aspects such as hygiene, nutrition and improvement of livelihood achieved by the application of a certain sanitation system, as well as downstream effects.
- Environment and Natural Resources:involves the required energy, water and other natural resources for construction, operation and maintenance of the system, as well as the potential emissions to the environment resulting from its use. It also includes the degree of recycling and reuse practiced and the effects of these (e.g. reusing wastewater; returning nutrients and organic material to agriculture), and the protection of other non-renewable resources, e.g. through the production of renewable energies (such as biogas).
- Technology and Operation:incorporates the functionality and the ease with which the entire system including the collection, transport, treatment and reuse and/or final disposal can be constructed, operated and monitored by the local community and/or the technical teams of the local utilities. Furthermore, the robustness of the system, its vulnerability towards power cuts, water shortages, floods, earthquakes etc. and the flexibility and adaptability of its technical elements to the existing infrastructure and to demographic and socio-economic developments are important aspects.
- Financial and Economic Issues:relate to the capacity of households and communities to pay for sanitation, including the construction, operation, maintenance and necessary reinvestments in the system. Besides the evaluation of these direct costs, the external costs and indirect benefits from recycled products (soil conditioner, fertiliser, energy and reclaimed water) have to be taken into account. External costs include environmental pollution and health hazards, while benefits include increased agricultural productivity and subsistence economy, employment creation, improved health and reduced environmental risks.
- Socio-cultural and institutional aspects:the criteria in this category refer to the socio-cultural acceptance and appropriateness of the system, convenience, system perceptions, gender issues and impacts on human dignity, the contribution to food security, compliance with the legal framework and stable and efficient institutional settings.
The old man would have concurred with these principles. Ok! So, what kind of products at household level and systems at city level come about by using these principles? Well, let us begin with products. In different contexts, the products would be different.
In the urban institutional context, one product from the sustainable sanitation movement is the “waterless urinal”. The waterless urinal is a product which saves between 40,000 to 75,000 litres of freshwater per urinal seat per year. In this context, IIT Delhi has taken a lead and converted about 100 urinals in the academic complex to waterless urinals. The conversion of existing urinals to waterless urinals has been carried out by Ekam Eco Solutions – an IIT Delhi based startup company. To know more about Ekam Eco Solutions, look up www.ekamecosolutions.com
In the rural household context, there is the “urine diversion dry toilet” which opens up the possibility of treating pee and poo as resources! The yellow line output “pee” could be used as liquid fertilizer – rich as it is in nitrogen and phosphorous and the brown line output “poo” gets composted – so as to ensure pathogen destruction before being used as soil conditioner.
- Globally, India has the largest number of people, more than 620 million still defecating in the open. About half the population of India use toilets.
- India, at the current rate of progress will only achieve the sanitation target of MDG 7–c in 2054.
Applying sustainable sanitation at city scale, one begins to study nutrient cycles – Phosphorous and Nitrogen recycling. City scale sustainability requires adoption of closed loop approaches – in which the phosphorous and nitrogen which came from the farm and fish, through the food into our bodies, return to those very ecosystems. A global research coordination network by name Phosphorous RCN is researching into global P cycle to better understand P sustainability by recycling Phosphorous effectively and also by enhancing its use efficiency.
What can you do to promote sustainable sanitation? You can join UNICEF’s digitally led campaign to campaign for open defecation free India “Take Poo to the Loo”. But why this campaign? Because, daily 620 million Indians are defecating in the open. That’s half the population dumping over 65 million kilos of poo out there every day. If this poo continues to be let loose on us, there will be no escaping the stench of life threatening infections, diseases and epidemics. Log on to the website www.poo2loo.com and take a pledge to campaign for eliminating open defecation.

Are Waterbodies the poor man’s sewage sinks? And are the city’s poor doomed to live in areas prone to chronic sanitation, drainage and water logging problems?
The results of a GIS mapping based study done by FORCE and funded by GIZ as a part of its ICPP program, certainly seems to say so. This study was done to explore the linkages between water bodies in Delhi and resettlement colonies.
In terms of the status of sanitation in resettlement colonies, the study echoed the observations often voiced by Non-profits – that those are not substantially better than the conditions in unauthorized slums. The alarming fact revealed by the study is that prima facie, it seems that the poor sanitation condition has a far more basic genesis than was earlier assumed.
So far, social workers have assumed that the poor sanitation conditions are only because of a lack of co-ordination between the multiple authorities involved in rehabilitation of the poor. Delhi has a unique problem in this respect owing to the duality in its governance by both the central and state governments. Our detailed case studies verified this fact but also revealed another shocking fact.
Our detailed case studies revealed that it took a minimum of 10 years and upto 26 years from the time of construction to bring sewer lines into a resettlement colony! Organized garbage disposal systems seemed to be last on the priority list of the planners since it is not present even after 26 years in some areas. This means that for atleast 10 years, the residents of a resettlement colony live without any access to sewage and garbage disposal systems.
The resultant unscientific, unplanned and unhygienic coping up methods followed by residents are largely responsible for the horrible state of sanitation in these areas.
The most critical revelation of our study was, however, was that the Resettlement colonies were doomed to be plagued by sanitation problems from the day they were conceptualized. The reason is that there seems to be a clear tendency of Resettlements to be located within the core catchment of one or more water bodies.
In 90% cases, water bodies are located either within the boundaries of the resettlements or within a 1.5 km buffer zone. Thus, the land selected for the resettlements was topographically placed in a depressed zone. As a result there was an inherent tendency of the area to be waterlogged – an observation that was verified by the interviews conducted with residents of those areas. More importantly, the negative slope would make it difficult or very expensive to link the area’s internal sewerage and drainage with the peripheral trunk lines.
The fact that after 1990, there seems to be a clear trend towards locating the resettlements in the northern peripheral wards of Delhi, further writes the obituary of sanitation. Being the outermost, least developed parts of Delhi, there are no sewer trunk lines or garbage disposal points in the vicinity of any of the new resettlements. Hence, even if internal sewer lines are laid, there is no planned outfall for the sewage. The high water table in these areas makes the situation worse, as it not only makes sewage disposal difficult but also makes the groundwater more susceptible to contamination due to sewage seeping from internal drains and water bodies.
Thus the study unfolded a dual tragedy – the institutionalization of the neglect of Water Bodies and the neglect of the poor. It has shown a deliberate act of the government in choosing to make resettlement colonies within the core catchments of water bodies. Not only is this disastrous in terms of sanitation provisions for the resettlements, it sounds the death knell for water bodies too.
The key conclusion that emerges from this study is that, water bodies are playing the role of sanitation waste sinks even for planned resettlement colonies. In view of this and the fact that the choice of location makes the resettlements vulnerable to failure of sanitation systems, the policies governing Resettlement Planning need to be re-examined.

It feels wonderful to be a sanitation practitioner and expert, living in a time and in a country where sanitation is almost on the verge of becoming a national obsession in both policy talks and programme implementation. This has been triggered by the launching of Swachh Bharat Mission (SBM) from the ramparts of Red Fort by Honourable Prime Minister of India Sri Narendra Modi.
SBM, the newest version in the not so long history of sanitation programmes in India, encompassed urban areas in its mission, increased the sanitation financing and linked open defecation free concepts on behaviour change with an unprecedented construction drive of individual household sanitation facilities across the country.
However, in spite of this much needed and renewed obsession with sanitation, there is hardly any paradigm shift or conscious efforts to re- engineer the sanitation programme in rural and urban India against the backdrop of our centuries old track record of dodging the issue. My thought on the main pillars of this process of re- engineering sanitation in India are based in breaking some key myths related to the sanitation programme in India. These are outlined below.
Myth # 1 – the cost of a sustainable household Toilet is Rs. 12000 as per incentive offered under SBM (Rural)
Perhaps this is the biggest myth among implementing organizations for both states and people. SBM offers an incentive for household toilet construction not a subsidy-. The results of this myth have been devastating to the sanitation sector. Consider this. Many implementing organizations in states and therefore people in rural areas have this notion that they have to construct a toilet in 12000 odd rupees received by government – means they trust that Rs. 12000 is the cost of a sustainable toilet in their household across a diverse and vast country like India.
Even a novice civil engineer will tell you that the cost of a sustainable household toilet will vary from place to place and will require some greater co-financing by the household as per their aspiration level, choice of material for construction and technology (e.g. Septic tank, twin pits, bio toilets etc.) and add on features such as storage tank, hand washing facilities etc. Therefore, it is important to take the message to the implementers of SBM and people that adherence to technical design and drawings of different kinds of sanitation systems for toilet construction and co- financing is key to sustainable sanitation, no matter what it costs. Based on their affordability and preferences, the household can choose a toilet design based on available on-site or off- site technologies in the area.
Year after year , there is increasing demands from state governments to the central government to increase the subsidy ( oops .. incentive) from Rs.12000 to up to Rs.25000 based on the understanding of state governments of what it costs to construct an household toilet ( latrine cum bathroom with hand washing facilities ). Obviously, state government’s want 100% of the cost of Individual household toilets to be subsidized. But there is a catch here. Catch number 1 is that the sense of ownership of a toilet which is completely constructed using government’s incentive is less therefore it is more unlikely to be used by all family members. Catch number 2 is the Community led Total Sanitation Approaches (CLTS) which triggers people’s action to become opendefecation free communities and has been widely used by developmental agencies in India for promotion of SBM. Prompting complete financial dependency for the construction of household toilets on government agencies (100% subsidy for cost of toilet approach) dismantles the very basic premise of CLTS- that people and communities can take charge to go for open defecation free using appropriate sanitation options ensuring sustained behaviour change based on community pressure. As a result, what we see of CLTS in India is a tool for Information, Education and Communication (IEC) rather than a tool for triggering community action in many cases.
Myth # 2 – The cost of sustainable sanitation is high and therefore this is a low priority among rural and urban poor.
Nothing can be as far from the truth as this notion. But this premise suits everyone and therefore it prevails as a deep rooted myth. So much so that even the poor have started believing in the status quo on sanitation. However, the good news is that it makes sense to invest in a sustainable household toilet by rural and urban poor. Consider economic benefits from sustainable household sanitation. If you explain to an ordinary citizen thatIndia loses 6% of its GDP due to lack of adequate sanitation, the likeliness that this resonates with them is bleak except for being informed of some interestingeconomic data. However when you explain toa family of 5 persons that by not having a household toilet,their family is losing out annually an amount of Rs. 10250 /- approximately on health expenditurewhich could be easily saved, There is a high chance that that you get an affirmative nod, listening ears and engaging minds.
Figure-1: Loss due to inadequate sanitation
Most of the estimates say that a sustainable and aspirational individual household toilet (a latrine cum bathroom with handwashing facility) is achievable within Rs.15000 to Rs.30000 per unit (connection to sewerage /Twin Pit/ Septic Tank with seepage pit /Bio Tanks with Seepage pits). However, the incentive to the eligible beneficiaries under SBM urban remains limited to Rs. 12000/ per household in rural areas and Rs. 8000 to Rs. 13000 per household in urban areas in many states.
The argument that needs to be taken to the people is that it makes perfect economic sense to invest in a sustainable and aspirational toilet even if they have to co- finance the cost by an additional amount required to construct a sustainable and aspirational toilet, as the benefit cost ratio (estimated to be 7.7 in case of SE Asia as per one of the studies) of construction of sustainable and improved toilet is too high to ignore. With MFIs getting increasingly involved for soft loans for sanitation financing by household and Corporate Social Responsibility (CSR) funds being increasingly committed to support SBM, the time could not have been better to break this myth. In turn, to help people with getting access to their aspirational and sustainable toilet and access to sanitation financing. This indeed will ensure to plug the leakages between toilet construction and its usages and also increase the life of a toilet to live its full design year at least, if not more.
Myth # 3 – Of technological puzzles , perceptions and realities
There are a number of myths associated with sanitation technologies being implemented under SBM (Rural) and SBM (urban). How often do we hear that on-site is better than off -site sanitation solutions in the Indian context? You may also hear of the poor quality of Septic Tanks being constructed and therefore surrounding pollution. How often do we attribute governance/management/planning failures to technological failures, for example the. performance of Sewerage Networks and Sewerage Treatment Plants.
The point here is that the implementation of SBM will need all the technologies that are available and probably many more for sustainable sanitation solutions which are context specific, affordable and require minimum operation and maintenance interventions or costs. However, there are no silver bullets here because each of the technology needs to be managed. These myths related to technological puzzles, perception and scientific realities can be overcome by bringing in this knowledge and expertise within the domain of each household in a language which can be best understood by them. The best suited for the role of scientific communicators can be school and college children and therefore it is important to make this simplified technological knowledge on sanitation as part of curriculum and discussions in the schools and colleges of India.

India has a serious sanitation challenge; around 60 per cent of the worlds open defecation takes place in India. Even today, only around 28,000 gram panchayats out of 2.5 lakh in India have achieved the Nirmal Gram (open defecation free village) status. Poor sanitation causes health hazards including diarrhoea, particularly in children under 5 years of age, malnutrition and deficiencies in physical development and cognitive ability.
We have to work with children and communities to realise their right to clean and adequate qualities of drinking water, sanitation and hygiene since they have direct bearing on the right to life and dignity. Lack of these entitlements and services in the communities put children at risk of disease and mortality. When access to water is difficult or schools are without toilets, many children (especially girls) face increased burdens on their time and risks to their learning and safety. Lack of Operation and Maintenance (O&M) funds and dedicated workers for toilet block maintenance results in slip back. Poor and marginalised families who are living with income poverty find it challenging to pay for these services hence the emphasis is on invoking the responsibility of the government for its provision.
We have to address the issues of poor sanitation, which seep into every aspect of life – health, nutrition, development, economy, dignity and empowerment. It perpetuates an intergenerational cycle of poverty and deprivation. To meet the country’s sanitation and hygiene challenge there is an urgent need to focus on triggering the demand for improved sanitation facilities, ensuring their quality, use and maintenance. This is achieved by creating a culture of “social sanctions” that challenges the acceptance of open defecation once and for all. Making this happen requires substantial resource and time investment to inculcate a lasting change in behaviour and adoption of key hygiene practices at the community and household level.

Leave No One Behind is a call to listen and learn by putting people in the centre, asking them what they need and valuing the one in everyone. It is based on the belief that human beings come in different shapes and sizes and a single solution cannot meet their diverse needs. WASH services are mostly designed to meet the needs of the mainstream, dominant community. But what happens to those that are traditionally left behind … the last mile … adolescents, pregnant women, the elderly, people with disabilities, migrant workers, rag pickers, transgender people? How do they take care of their daily sanitation and hygiene needs? What are their challenges and aspirations? Do they have insights and suggestions to improve sanitation services?
The Kathmandu Declaration from the fifth South Asian inter-ministerial conference on sanitation (SACOSAN V) recognized the importance of “addressing diversity in service provision for infants, children, youth, adolescent girls, women, people with disabilities, chronically ill and elderly in rural area and people affected by poverty…” and committed to significant direct participation of these groups in SACOSAN VI, Dhaka and systematically thereafter. (Commitment X)
As part of the preparation for SACOSAN VI in Dhaka, the Freshwater Action Network South Asia (FANSA) and Water Supply and Sanitation Collaborative Council (WSSCC) organized a consultative process with marginalized groups in South Asia to listen to their sanitation and hygiene needs, challenges, hopes and aspirations, as well as their suggestions for improvement. Over 2700 adolescents, women, elderly people, persons with disabilities, sanitation workers, rag pickers and transgender people participated in 55 consultations organized with the support of 70 local partners across Afghanistan, Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan and Sri Lanka. Read the Leave No One Behind report for the key findings and watch the film to hear interviews with participants.
Across these 8 countries, this was the first time many of these groups were being consulted on their sanitation and hygiene needs, challenges and aspirations.
Here is what some of them said …
“My daughter does not go to school when she is menstruating because she is embarrassed and feels that the male teachers may not understand her. There is no counseling for girls in school to explain how to manage menstruation hygienically. Girls tend to change their sanitary materials infrequently because they are not aware of the risks and due to economic reasons. Some of them use the same cloth for one and a half days!” – Adiba Qureshi, Afghanistan
“Once I fell on my back while going to the toilet behind my house and dislocated my back bone. I have had pain ever since. Now, I tie a cloth around me and pass urine standing like a man does. What else can I do?”- 80-year old Yellemma ,Warangal, Telengana, India.
“I need a bathroom which has support I can hold on to, otherwise I will lose my balance. A one-inch wall will easily collapse if I fall on it. That is why I want a bathroom to suit my need.” – Suman, a wheel chair user, Ranchi, Jharkhand, India
“As part of our work we sweep, pick up garbage, clean drains and pick up dead animals. The dead animals smell real bad. We don’t get a mask, gloves or shoes to cover ourselves. If people can’t bear the dirty smell, imagine what we have to bear while picking up a dead dog.” – Shankar Mukhi, Sanitation worker, Saraikela, Jharkhand, India
“We do not know which washroom to go to – ladies’ or gents’? The moment we visit the ladies’ toilets, women are either scared or make fun of us. When we go to the men’s toilet, we are assaulted. I am now scared and avoid using public toilets.” – Jaya, Transwoman, Bangladesh
So, is it just a question of more taps and toilets? Would infrastructure alone help to change mindsets and eradicate stigma and discrimination that prevent transgender people, like Jaya, from using public toilets or adolescent girls like Adiba’s daughter from going to school when she has her periods?
In January 2016, twelve community representatives who had been a part of the consultative process participated in a plenary session at SACOSAN VI, Dhaka. They eloquently shared the sanitation and hygiene challenges and aspirations of their constituencies with the audience of Ministers and key decision makers of participating governments, practitioners, academics, civil society and private sector agencies. The Dhaka Declaration is a testimony to the influence this session had on policy makers.
The Leave No One Behind consultation process is an important, first step towards addressing equity and inclusion in sanitation and hygiene. However, we need to continue and deepen this process by creating more platforms for constructive dialogue, so that duty bearers can listen to the needs and aspirations of marginalized groups and include them in the design, delivery and management of sanitation services.
For, unless we put the last mile first and listen, they will continue to be left behind.

The Swachh Vidyalaya Initiative taken up since August 2014 by the Ministry of Human Resources Development under the government’s Swachh Bharat Mission (SBM) has aimed at providing toilets, for both girls and boys, in schools that don’t have these facilities. It also aims at making defunct school toilets functional. Further, the initiative emphasizes the need to have strong demand / behavior change campaigns to inculcate safe sanitation among children, and through them their parents and families – to consistently use toilets and not practice open defecation, maintain their toilets and also instill strong habits around hand washing.
While no comprehensive assessment of this programme is available so far, construction achievement figures are available and are being tracked from across the country. While the news around construction of toilets is encouraging, the larger issues around usability, availability of water, etc. are still far from satisfactorily being addressed.
It has been assessed in the latest Swachhta Status report that 4.17 lakh toilets were constructed in 2.61 lakh schools and the target has been achieved. Of this number, only twelve corporate houses have constructed 3,466 toilets. .
Ground reports from various areas including states in the North East and East point out that a majority of toilets in water stressed regions are yet to be handed over to school authorities, since no adequate provision for water supply has been made. This seems to be a major challenge and needs to be addressed. Water experts say integrated water resources management is key to solve this crisis.
