Making a pico-hydro electric system

AIDG’s Technology R&D Program is pleased to present a new series of technical documents that have been produced during various projects we have worked on in the last 5 years. During the first 3 years of the program, the documentation was produced in a haphazard way, but around the beginning of 2008 we realized that that wasn’t going to provide a good base for future work the way that more systematic documentation could. Since that point, we have tried to document projects more thoroughly as they are ongoing, so that the information isn’t lost and we and others can build on the work that has been done. During the last year, we have been extremely lucky to have intern Ben Dana undertake the arduous task of pulling together information from many of the previous projects and put into one place.

In presenting these documents, we would like to accomplish two things. First, we would like to provide anyone who is interested the opportunity to learn from our mistakes and our successes, to see a bit of the process we have gone through in different development projects, and apply those lessons to their own projects. Second, we would like to tap into the worldwide appropriate technology community and stimulate further development of the technologies we have worked with.

We’re still developing a plan for how to best stimulate this type of development. In the next few months, we hope to pursue alliances and implement tools to allow the information to spread as far as possible, to encourage people to do further work, and to provide a forum for discussion of that work and presentation of results. In the meanwhile, we’d like to present several documents, and we invite everyone to comment on them, on anything and everything that comes to mind. We’re looking for feedback on format, appearance, the type and quantity of information that the documents contain, and anything else.

    AIDG Haiti Update: Structural Assessments and Masons Trainings

    School Collapse at the Petite Ecole Francaise in Cap Haitien, Haiti
    School Collapse at the Petite Ecole Francaise in Cap Haitien, Haiti

    I got the call in the morning on Feb 16. Edline Estimable, our bookkeeper in Haiti, was in shock, utterly distraught. An elementary school down the street from our office in Cap Hatien had just collapsed just days after schools reopened. Several of her friends’ children attended the Petite Ecole Francaise. Already wrung out by the events of Jan 12, she couldn’t bare to say it or even think it, but she knew deep down that some of her friends’ kids had been hurt if not killed. But what happened? There had been a lot of rain in Cap that was for sure, but there hadn’t a new earthquake, not even the mildest tremor in Haiti’s 2nd largest city (100+ km away from the capital Port-au-Prince). It turns out it was a mud and rockslide. The school abutted too close to a rocky hillside. The rains had softened the earth; boulders and mud slipped and slalomed down, crashing through the school’s roof. Four 8-10 year old children died — 3 girls and a boy. Edline knew 2 of them. 8 others were wounded.

    Jessica Lozier, our interim Haiti Program Manager, had just picked up our 3rd team of structural engineers from the Cap airport when the accident happened. This had been a week of horrors for Jess. A few days before she had been in Port-au-Prince and had witnessed a horrific hit-and-run. She and our colleagues at SOIL helped bring the injured pedestrians to the nearest hospital. Now in Cap, she was helping pull out some of the hurt children as well as translate for foreign doctors who had been volunteering in country.

    <a href="

    “>From the Miami Herald:

    “It was madness,” said Jess Lozier, coordinator for Appropriate Infrastructure Development Group, who arrived at the scene an hour after the accident. Lozier’s group works to provide sanitation, electricity and clean water to developing countries.
    Haitian National Police officers and doctors from the group Help Haiti Heal scrambled to dig surviving children from the rubble, as did U.S. Army troops. It was not known how many other children were in the classroom at the time.
    “The director of the school said all the other kids were accounted for,” Lozier said.

    In the aftermath of this accident, schools reclosed. The 7.0 earthquake in Pap had shown that schools were some of the least seismically resistant buildings in the city. Parents all over the country were already very much afraid and now this.

    What’s wrong with the current building techniques used in Haiti?

    While the school tragedy in Cap was not related the earthquakes per se, it further underscored the shoddy construction of buildings all over the country, not just in the metro Port-au-Prince area.

    Andre Filiatrault, director of the Multidisciplinary Center for Earthquake Engineering Research (MCEER) who led our 1st team of earthquake engineers in January, lists the following issues as primary problems:

    • Unreinforced masonry structures
    • Lack of symmetry
    • Lack of transverse reinforcement
    • Poor quality of concrete
    • Reinforcing bars without ribs
    • Quality of construction
    • Lack of building codes

    In an interview with NPR, Craig Totten from KPFF who we have been working closely with, had this to say:

    [W]hat he and [Darlene] Clovis have seen, in building after building, is soft mortar, poorly mixed concrete and rickety columns. The cinderblocks are made from material so grainy that it peels away with your fingernails.

    What is AIDG doing?

    If you’ve been following this blog, you know that we’ve been working with groups like MCEER, KPFF Consulting Engineers and the Association of Haitian American Engineers of New York to perform structural assessments of standing and partially collapsed buildings for the government, the UN, NGOs and the community.

    To date we’ve reviewed over 1250 structures. For our small staff, this has been a monumental undertaking. The team on the ground now in Haiti hasn’t had much of a break timewise or emotionally.

    In the weeks after the earthquake, it was clear that homeowners, business owners, private citizens, and masons needed more than just reviews. If they were going to prevent the countless needless tragedies, they needed information on how to build back better. We know that most of the damaged and destroyed homes will be rebuilt by private citizens and local contractors out of masonry, concrete and steel. Without access to information on better building techniques, the same deadly mistakes that brought down houses in the quake will be made. So in partnership with Architecture for Humanity and KPFF, we’ve begun to retrain masons in Port-au-Prince, Léogâne and Jacmel in confined masonry techniques. The same techniques have been used in Chile to make buildings there resistant to earthquakes 700 times stronger than the one seen in Port-au-Prince. Here I must commend the leadership of Craig Totten, a principal at KPFF who got the partners at his firm to commit to sending a rotating roster of their engineers to Haiti to continue doing assessments. He’s also recruited masons in the Portland area to work with us to perform trainings of masons.

    Craig McMurtrie from ABC Australia accompanied the team (Craig Totten, Shawn Anderson, Darlene Clovis, Clem Fleck and Robert Miller from Portland based Fleck Masonry and AIDG’s Adajah Codio) on a mason’s training in Jacmel and filed this story:


    Duration: 5 minutes 58 seconds

    To date we have trained approximately 560 masons. Our initial goal with this project is 3000 over 10 months. At the rate that we’re going now, we think we can bump that number up to 10,000, but it all depends on funding. We need $190,000 – $250,000 to hit that goal.

    In terms of curriculum we’re using a translated version of “Construction and maintenance of masonry houses” by Pontificia Universidad Católica del Perú and SENCICO, originally edited by Marcial Blondet. The translation was crowdsourced by volunteers from Haiti Rewired, a project of WIRED.com. The April 12, 2010 Kreyol version can be found here. Graphics are currently being upgraded to better reflect the building styles in Haiti.

    Video: Viva Rio's public toilet biogas plant


    Duration: 2 minutes 34 seconds

    08 December 2009 – UN MINUSTAH: The “biodigestor” – a pilot project in a poor neighborhood in Port-au-Prince is making methane gas for electricity, using human waste from public toilets. If successful, the project would provide an alternative, green fuel to wood charcoal, and could help the country overcome its massive environmental problems linked to deforestation.
    One poor neighborhood in Haitis capital, Port-au-Prince, is the scene of a new pilot project that will provide new sources of energy, and improve basic sanitation on the streets.

    The project starts with some public toilets. Here, for the price of about a penny (US$0.01) residents have the chance to clean up, and use the bathroom. In most Haitian cities, people dont have access to running water. So modern toilets are a real luxury. Particularly when they are open to the public.

    SOUNDBITE (Creole) Aline Saint-Fort, Public Bathroom Attendant:
    Other public toilets are no where near as clean. And they are expensive. In most places in the city you pay five or even ten cents to use the bathroom thats ten times what we charge.

    With the capacity to take one thousand users a day, the project hopes to improve sanitation. But the real benefit is a by-product produced in the yard outside. Engineers with Viva Rio, the Brazilian NGO that runs the project, built this large underground reaction tank called a biodigestor. Inside it are bacteria that are transforming human waste into methane gas a biofuel that can be used as a powerful, and virtually free, source of energy.

    SOUNDBITE (Portuguese) Valmir FACHINI, Project Coordinator, Viva Rio:
    The way it works is simple. The waste comes from the toilets, and gets dumped into the reaction tank. This starts the fermentation process, the produces bio-gas. The gas crosses a column of water, and comes to rest at the top of the tank. This bio-gas can be used for cooking and electricity.

    The fermentation inside the bio-digestor also enriches the roots of the surrounding foliage, which act as a filter for liquid waste.

    SOUNDBITE (Portuguese) Valmir FACHINI, Project Coordinator, Viva Rio:
    This reactor has a capacity to produce fifty cubic meters of biogas per day. This will generate 3000 watts of electricity per twenty four hours.

    Biogas is cheap and easy to produce. If the project is replicated, it could give Haitians green alternatives to charcoal fuel. This would combat deforestation the underlying cause of the countrys massive environmental problems.

    And thats not all. Filtered water coming out of the bio-digestor is rich in nutrients and can support many forms of plant and animal life. Ducks feed on insect larvae. And fish prosper here. With proper care this pond will become a fishery, creating food and jobs in the neighborhood.

    SOUNDBITE (Portuguese) Valmir FACHINI, Project Coordinator, Viva Rio:
    Here in these tanks, the water comes rich with nutrients. The sunlight permits the production of algae. And the algae are the primary food source for fish.
    So one pilot project in Port-au-Prince is helping an underserved neighborhood to produce green energy and improve sanitation at the same time.
