Re: Self Sustained eToilet for households/ Urban-semi urban Public/ Community Sanitation (Eram Scientific, India)

Eram Scientific @Reinvent The Toilet Fair-New Delhi, India 2014

Eram Scientific unveiled the first-ever eToilet Imperial Model during the Reinvent The Toilet Fair held in New Delhi, India on 21st & 22nd March 2014. Along with this, eToilet School Model and General Public Model served as frontend systems for the treatment units of Duke University and CALTECH. Eram Scientific Solutions’ project was one of the 50 exhibits displayed during the two-day fair.

The Reinvent the Toilet Fair: India aims to stimulate discussion and spur partnerships to improve global sanitation and bring affordable sanitation solutions to people who need it most. The fair is also an opportunity to recognize India’s leadership and commitment to improving child health and fostering innovative solutions to persistent development challenges. The fair is also supported by the Indian Ministry of Housing and Urban Poverty Alleviation and Ministry of Urban Development.

The Imperial Model offers salient features like:

• Coin/Card based Access Control
• Self-washing & Cleaning Mechanisms
• Sensor-enabled water conservation
• Automatic Seat Sterilization
• Vacuum Flushing Mechanisms
• Air-conditioned Interiors
• Stainless Steel Built-up
• Touch-free Switches
• European Styled Squatting Pan
• Automatic Urinal and
• Sensor-enabled Wash Basin

ESS is now developing eToilets that are self-sustainable and Nutrient-Energy-Water recovering and which meets international standards. ESS is collaborating with other grantees of the Bill and Melinda Gates Foundation for recovering water, energy, fertilizers or a combination of one or more of them through suitable sewage management solutions. It is expected that these projects would ultimately make eToilets self-sufficient in water and energy requirements.

Re: Self Sustained eToilet for households/ Urban-semi urban Public/ Community Sanitation (Eram Scientific, India)

Thank you Joe.

We indeed recognize this as a great challenge and are extremely honoured to be selected. We propose to develop, prototype and do a field trial of a cost effective eToilet model in a specified user community and integrate with the NEWgen reactor developed by University of South Florida (see: forum.susana.org/forum/categories/98-res...-now-in-kerala-india). We are extremely glad to collaborate with the team of Dr. Daniel Yeh, who is currently visiting us in Kerala for initial discussions and site surveys for carrying out the field trial. He has held a fruitful discussion with our R&D team.

Through this project, we propose to demonstrate a cost effective eToilet (we definitely would like to retain the self cleaning capabilities of the eToilet)design and develop using current and or alternate materials without comprising on the ruggedness and sturdiness of the structure, develop the prototype and go to the actual user site with the NEWgen integrated. The value which the NEWgen is expected to bring in is in terms of generating the water and energy required for running the eToilet. We expect that this project would prove as a scalable technology for replication across India. Both the teams at Eram Scientific and @USF share the vision and we look forward to this great opportunity.

Warm Regards,
Bincy

Re: Self Sustained eToilet for households/ Urban-semi urban Public/ Community Sanitation (Eram Scientific, India)

Dear all,

For those of you who are interested in the research project of Bincy on those etoilets in India ("Research on Self Sustained eToilet for households/ Urban-semi urban Public/ Community Sanitation"), I am giving you below a summary of what was in the expert chat about her project (the expert chat was mentioned here: forum.susana.org/forum/categories/139-ge...te-sept-12-2013#5624)

Bincy's part stats at 30:30 into the recording, i.e. here:



Unfortunately, there was a problem with synchronising her voice with her slides during her presentation. But you can view her presentation here (nice, colourful photos!):

At 33:06 into the recording, the short question session starts:



Nelson asked her if she could explain more about the self sterilisation, self-cleaning mechanism.

Answer by Bincy: It is all entirely sensor-based. The sensor picks up when someone enters or leaves the toilet. After the user has exited the room, the toilet flushes by itself (in case the user forgot to flush, I presume). If the user was on the toilet for longer than 3 minutes, more flushing water is used than if it was less than 3 minutes (assuming that more than 3 minutes means the user defecated; less than 3 minutes: it is assumed the user only urinated).

Also, the toilets are squatting type toilets, which means they are level on the ground. As the toilets do get muddy and dirty from people's shoes, there is a floor cleaning mechanism that comes on after 5-10 users (I wonder: does this generate perhaps an unnecessarily large amount of wastewater?).

Arno also asked if the toilets are connected to the internet and continuously monitored on-line?

Bincy said: yes.

Arno pointed out that these are the first toilets worldwide wtih real time functional data. (I wonder: is the performance of the wastewater treatment then also monitored as closely and available online?).

Arno also pointed out later in the summary that Bincy's toilets were generating money through advertising on the outside of the toilets. (I wonder: is this amount significant? What fraction of the O&M costs could the income from the advertising cover?)

Re: Self Sustained eToilet for households/ Urban-semi urban Public/ Community Sanitation (Eram Scientific, India)

Dear Bincy

Thank you very much for your participating in this interesting expert chat. (for more information on the expert chat, see here: forum.susana.org/forum/categories/139-ge...nment-institute#5638)

Unfortunately not all of your presentation could be recorded, but as I have been present and based on your presentation I do have a few further questions.

I understood (and please correct me if I am wrong) that the toilets are "self-sustained" and that "there was no inlet nor outlet". Well, there must be at least a inlet: without pee and poo it wouldn't be a toilet, its it? :-)
However, I tried to find out what is exactly meant with this and found at the end of the presentation only "Toilets which are self-sustainable, creating its own energy and water for its functioning and also powering the external environment."
So I went back to your initial post (forum.susana.org/forum/categories/105-pr...cientific-india#3663) and found out that they are actually either connected to the existing water supply and drainage system or to a biomembrane reactor.

This sounds similar to the concept of the blue diversion toilet presented by Tove.
-> Can you also give us some further indications on what type of treatment and recycling technologies your are using?

Best regards

Re: Self Sustained eToilet for households/ Urban-semi urban Public/ Community Sanitation (Eram Scientific, India)

eToilets in newfangled stainless steel outfit:

It has long plagued the minds, and bladders, of people of Pollachi: where is the closest public toilet, and what squalid horrors will confront the user on arrival? But when nature calls, the Town of Pollachi listened and responded by initiating eToilet implementation in their region. The new version of eToilets – Stainless Steel Model (SS Model) has been launched in two locations in Pollachi, a small but very happening town in Tamil Nadu State, India. The eToilets have been installed in two locations at Pollachi viz; Round Road Park and Government Girls Higher Secondary School. These toilets will be a welcome relief to both the visitors to the park and the girl students in schools.

The eToilet SS Model has been redesigned to form a sleek, compact and attractive sanitation infrastructure. With a built space requirement of less than 25 square feet, the new eToilet model offers several unique features like highly durable enclosure, built with steel, sleek and innovative design, user friendly interfaces, sensor-based functionalities, environment friendly sewage treatment and remote management capabilities. eToilet has also integrated technology to ensure cleanliness and hygiene and conserve water and power usage. Eco-friendly sewage management is made possible through the integration of Anapackage, an anaerobic sewage treatment system.

The support rendered by the Pollachi Municipality was instrumental on the successful implementation of eToilets here. Another 4 eToilets are in the pipeline for Visakhapatnam, often called “The Jewel of the East Coast”, located in the State of Andhra Pradesh, India.

Re: India's First Connected eToilet Infrastructure

Information on the availability of public toilets is quite relevant to serve the citizens. Recognizing the need for providing safe and clean public sanitation amenities and disseminating information, several countries have come up with innovative sanitation solutions such as Australian National Public Toilet Map, Great British Public Toilet Map, to name a few. These information resources are of immense benefit to the public and travellers as well as to the highly vulnerable sections like the aged, women and children. Contextualizing the emerging need for a similar solution in India, Eram Scientific Solutions has developed and implemented India's First Connected eToilet Infrastructure to revamp the sanitation landscape of the Country as a whole.

Re: Self Sustained eToilet for households/ Urban-semi urban Public/ Community Sanitation (Eram Scientific, India)

Hi Kevin,
The doc. potty project was highly informative and insightful. Thank you for that.We could relate to a number of issues you have listed in the document especially w.r.t the design and O&M.

I am also happy to share the link to our websites which provides more details about our project.
www.eramscientific.com, www.delightbharath.com

I have also seen that you are engaging caretakers from the communities for managing the toilets. Recently we have launched an entrepreneur model in public sanitation called eToilet eShop (eTeS ) Project. Here, an entrepreneur from a marginalised community will be provided with an eToilet and an electronically operated Shop in an urban location. There will be part-funding/soft loan by the local body. This ensures that the entrepreneur gets ample income from e-toilet as well as from sale of goods. Considering the plight of street vendors in India, we are trying to link our business model with the street vendor community as well. In Kerala though we are working on a high end model for urban public models, we are exploring how a customised rural entrepreneur model can be implemented with Kudumbasree a strong self-help group movement based in Kerala. A pilot launch was carried out in Kozhikode corporation last week. Pls. see the link below.

Re: Self Sustained eToilet for households/ Urban-semi urban Public/ Community Sanitation (Eram Scientific, India)

Hi Bincy!

Oh yes, we can most assuredly relate to these; we've faced the same in varying degrees while working in Bhubaneswar and Cuttack.

Issues A and C are somewhat related in my mind. One aspect of our project that has been both extremely helpful and rewarding has been our community engagement activities. During the initial design process we conducted a lot of user-experience and feedback sessions to gain an understanding of not only how residents used facilities, but also what they wanted to see in a sanitation facility. We then tried our best to incorporate as many of their insights into the architectural designs to further the project's mandate to ensure the facilities we're building aren't just functional, but valued and "wanted". I imagine engagement sessions like these would help familiarize both users and investors while also making them feel like they're "part of the process". Granted, this requires engaging with both user sets early on in the design process. That said, post-design outreach, especially in an educational capacity, would seem beneficial.

Point B is a challenge close to our hearts, unfortunately. We're working in urban slums and face the same spatial constraint challenges. Identifying sites seemed to be just the initial challenge, though, as we also faced an uphill climb when it came to sorting out ownership details. For us, the only option was to curate a list of about 3 times as many sites as we needed to build on and go to the local municipal corporations to verify which ones were viable options for us. Thankfully, both BMC and CMC are partners on the project, which helped in the process, but it still took a great deal of research and site visits before we got a finalized list. I fear there's no other option but to cast a wide net and hope for the best with this!

Point D is also an issue that we had, thankfully, identified early on, during research for the Potty Project (pottyproject.in). This malfeasance was actually a chief concern for us during the design phase. We're fortunate enough to have caretakers at our facilities, and designed their space to ensure maximum visibility in hopes that this will drastically reduce theft and vandalism. I'm not sure what can be done in instances where there is minimal supervision.

Sorry, as I re-read this I realize that I've not given much insight into addressing these challenges other than to say I feel your pain!

Do you have a blog or website for the project? We've been fairly active in documenting our learnings along the way. If you're interested, you can check us out at ProjectSammaan.com.

Keep up the great work!

Re: Self Sustained eToilet for households/ Urban-semi urban Public/ Community Sanitation (Eram Scientific, India)

Hi Kevin,
sure. there were multiple challenges we faced at the field. Some of the most common challenges are
a. Getting the concept of electronics in public toilets among the buyer group was a huge challenge during our initial two years. We had demonstrated the product among different decision makers and authorities and had piloted it for a reasonable time for obtaining user feedback
b. Availability of suitable space for installation. As we started with Kerala, which is the most densely populated state in India, we found that availability of space is the most difficult challenge. Though e-toilet require less than 50 sq. ft. locating and allotting suitable space for installation took longer time tan expected in many of our installations

c. Resistance from local residence. Again due to the high density of population, in some cases, e-toilet initially faced resistance from local shops, residents , with a perception that it will produce bad odour and pollute their surroundings. But in the last 50 installations there were no such instances reported, from which we infer that due to greater awareness about e-toilet and due to its pro-environment functionalities , public resistance is weaning away.

d. Vandalism and theft; There were many incidents where the components of e-toilet like the health faucet, some of the sensors were regularly stolen, very sooner after a fresh replacement. But now such incidents are coming down due to grater awareness of the people and we have anti theft alerts inside the toilets.

Apart from these there were cases of non-availability of electricity or water connection, which caused delay in installation. Now we have obtained priority for obtaining connections since e-toilet being public service infrastructure installed by local authorities for the citizens.

As we progress, we face new challenges and roadblocks, but those have helped us a lot on improvising our product, its functionalities, our business models and our service methodologies.

I am sure you must also be facing similar issues at field. Would like to hear from you on how you tackle those.Our experience sharing would help both of us and other currently working in this sector.

Thank you !
Bincy

Re: Self Sustained eToilet for households/ Urban-semi urban Public/ Community Sanitation (Eram Scientific, India)

Hi Bincy,

I was very interested reading about your project, especially given the low per-use cost incurred by the communities that house them. Though this is a very vague question, I was wondering if you'd share some of the challenges you and your team have faced along the way. It'd be interesting to hear about the hurdles you've had to overcome to implement this.


Cheers and keep up the great work!
