Lifestraw and New Toilet Technologies
An innovative model to solve India’s Water and Sanitation Problem
Only 23% of India’s Rural population have access to Improved Sanitation
Facilities and the number is around 58% in Urban India.
About 90% of rural India has access to an Improved Water Source. The
number rises to about 97% in Urban areas.

Issues concerning Water and Sanitation in India:
1. Though a large part of the population has access to improved
water sources, majority of these sources are contaminated and
have dissolved solids greater than the WHO accepted levels of
500 milligrams per liter.
2. According to Yahoo, India alone is responsible for 60% of the
global population lacking access to basic sanitation. About half
of its 1.2 billion residents are mobile subscribers, but only 366
million people have access to toilets, noted a 2010 U.N. report.
3. A major concern is also the behavioural aspect of such issues
where villagers believe that their ancestors have been drinking
water from wells and so can they. They refuse to accept change.
The same is true in case of toilets and a large number of Indians
prefer to defecate in the open.

Lifestraw
TM
is an innovative solution to the drinking water crisis in India.
The sanitation problem can be addressed through specially designed toilets
which would require minimal water and also provide a large number of
benefits.

approach
Lifestraw is an ingenious water filter designed to purify 1000 liters of water.
It can kill 99.9999% of bacteria and 99.99% of parasites. It is designed by
Vestergaard Frandsen.
Funding on water purification projects should be done by the government
but implementation of the same should be undertaken by NGOs and VOs.
Special toilets designed by universities such as Caltech, Stanford,
Loughborough etc, can be used by the government on a large scale.
Part of the funding for these special toilets must come from the
community itself. This promotes usage as well as maintenance of these
toilets. 3
Lifestraw can help solve majority of problems related to
water borne diseases in India
• According to the WHO about 90% of rural Indians have access to an Improved
Water Source. The number rises to about 97% in urban India. Access to an
improved water source refers to the percentage of the population with
reasonable access to an adequate amount of water from an improved source,
such as a household connection, public standpipe, borehole, protected well or
spring, and rainwater collection. Unimproved sources include vendors, tanker
trucks, and unprotected wells and springs. Reasonable access is defined as the
availability of at least 20 litres a person a day from a source within one
kilometre of the dwelling.Source: eatdrinksurvive.com
• As a large number of people have access to water, we believe that the problem lies in purifying this water
to make it drinkable. We propose the use of a personal purifier such as the LIFESTRAW which can be used
to purify water without any other problems such as electricity or requirement of an operator.
• Similar devices can be developed by the IITs and can be thus provided at a lower cost.
• The benefits of the usage of such a purifier are enormous which include a reduction in water borne
diseases, clean drinking water to all, reduction in infant mortality rate etc. 4
Public-Private Partnerships are the way forward for efficient
implementation of various projects
• The Coca-Cola Company and the U.S. Agency for International
Development (USAID) have created a unique partnership to address
community water needs in developing countries around the world.
• The development projects are funded jointly by USAID and Coca-
Cola Company. Each contributing about 50% of the spending.
• The program has a reach of about 255,000 people who now have
access to clean drinking water.
• We propose a strategic alliance between government of India and cola
companies such as Coca-Cola, PepsiCo and Danone International to
implement water purifier installment and maintenance schemes.
• Reports suggest that PPP models have helped improve conditions in
Sub-Saharan countries as shown in the graph to the right.
• The maintenance of these purifiers can be taken care by either the private players or NGOs at the charge of a nominal
monthly fee required for cleaning the same and maintaining the purifier.
• Such a model has been successfully implemented in village called Chuddani where the water purifier is operated by Naandi
Foundation and has been installed by Danone International.
• Such a setup would avoid misuse of the infrastructure by villagers and also help in maintenance of these purifiers in the
long run.

Innovative smart toilets-the way forward
This toilet created by students of California Institute of Technology uses the sun to
power an electrochemical reactor. The reactor breaks down water and human
waste into fertilizer and hydrogen, which can be stored in hydrogen fuel cells as
energy. The treated water can then be reused to flush the toilet or for irrigation.
The toilet to the right was designed by Loughborough University. It produces
biological charcoal, minerals and clean water from human waste, using a
process they call “continuous hydrothermal carbonisation”. This is a kind of
high-pressure cooking followed by a drying and combustion process that ends
up producing carbonised pellets. The dried material can be used as soil
conditioner or as fuel for cooking or powering the sanitation system.

Innovative smart toilets-the way forward
This toilet designed by Eawag: Swiss Federal Institute of Aquatic Science and
Technology and EOOS of Switzerland diverts urine and recovers water for
flushing. The urine and faeces will be safely transported to a decentralized
processing centre. The water used for cleaning will be recycled by a gravity-
driven biological membrane.
Coming to our very own indigenous solutions to innovating toilets, this
toilet is a combination of a toilet and Biogas plant. The biogas plant can
satisfy the energy requirements for cooking in the family. This caters to
solve two issues at once. Sulabh International has also developed some
technology in this regard and the government of India can implement some
schemes using these affordable toilets

Why should the government spend such a large
amount of money on these innovative solutions??
• Inadequate sanitation causes India considerable economic losses, equivalent to 6.4 per cent of India’s GDP in
2006 at US$53.8 billion (Rs.2.4 trillion), according to The Economic Impacts of Inadequate Sanitation in
India, a new report from WSP.
• If the government even spent this amount of money on developing water and sanitation infrastructure in the
country, they would benefit the citizens as well as decrease spending of the government on various fronts.
• For example, the Caltech toilet creates energy and fertilizers apart from functioning as a normal toilet. Hence
farmers benefit with good organic fertilizers and also are independent in terms of energy needs. This
transforms into the government spending lesser on Fertilizer subsidies and electricity production.
• The water recycling toilets do not require a separate water source and hence the government will not have to
worry about how to bring water to these toilets. The biogas toilets help solve the problem of LPG subsidies
and also that of large spending on Kerosene.
• The implementation has to be region specific wherein the government has to use these solutions according to
the needs of the particular region. Thus the government has a dual incentive in using such schemes as they
solve the sanitation crisis and address other issues with the same.
8
Spreading the cost of infrastructure between the
users and the government – The 80-20 model
• In Ahmedabad, foundation grants to the Mahila Housing
Trust supported the provision of water, sewage, and toilet
connections for thousands of families living in 35 slums.
They adopted the model wherein 80% of the project was
publically funded and the remaining 20% was collected from
the actual users of this infrastructure.
• A few years after the facilities were constructed, customer
satisfaction surveys suggest that usage continued to be
around 80%.
• The main challenge is not only the erection of infrastructure
but also the maintenance and usage of such infrastructure.
• We propose the same model. Wherein we want the actual
users to pay a nominal sum in the construction of such
infrastructure so that they have a sense of responsibility and
at the same time try and use it more frequently.
USERS
GOVERNMENT
9
The real problem lies in changing the attitude of the
people in using the created infrastructure
• A major problem faced in implementing these schemes is
the fact that a majority of the people in India have no
qualms about drinking water directly from wells or
defecating in the open. They believe that their ancestors
have been drinking water from the same well and open
defecation is socially acceptable. Examples of the same
are cases where Sulabh Sauchalays have been converted
to grain storage centres.
• We propose that the issue can be tackled by hiring
volunteers from the rural areas. They can be provided
employment and at the same time it is easier to convey
the thought between two people who know each other.
