Beyond water trucking - HWT options
Olivier Mills
Cher tous,
Suite à la note sur le HWT sous-groupe, je voudrais vous faire connaitre les activités de quelques organisations travaillant dans le domaine du traitement d’eau à domicile (TED, HWT en anglais).
CAWST forme et soutient techniquement des organisations (locales et internationales) en Haïti sur le traitement d’eau a domicile depuis plus de 7 ans.
Une technologie qui s’est rapidement étendu est le filtre biosable dont plus de 20,000 (100,000+ personnes) sont utilises actuellement.
Bien qu’ils ne soient pas adéquats pour des situations d’urgence, ces filtres ont fait leur preuve depuis plus de 8 ans en Haiti (voir etude d’evaluation si joint) dans les contextes rural et urbains. Il existe également de nombreux entrepreneurs locaux dans le pays, capable de produire ces filtres.
Un aspect important dans la stratégie de traitement d’eau est le traitement contre les protozoan oocysts dont le cryptosporidia (fort présent a Port-au-Prince) éliminé par filtration et contre lequel la chloration n’est pas très effective. Dans le contexte de mis en place dans les ménages ruraux le filtre reviens environ a $35-55 (tous les couts indirect et de suivi compris), il n’y a aucun cout d’opération et maintenance et a une duré de vie de plus de 20 ans.
Sinon, voici également quelques fiches techniques pouvant faciliter la discussion initiale du sous-groupe HWT, sur d’autres technologies :

Voici la liste des organisations compétant dans le filtre biosable, en Haiti :

*** The English version ****
Dear all,
Following the email on the Household Water Treatment (HWT) sub-group, I would like to put you in touch with a few organizations working in the area of HWT in Haiti.
CAWST has provided training and continuous follow-up support on HWT to local and international organizations and agencies in Haiti for the past 7 years.
The biosand filter is one of the technologies that has gained significant interest from many organizations and donors.. We have estimated over 20,000 filters (100,000+ people) currently use them all over Haiti, mostly in homes, but also schools and clinics.
The biosand filter is not suitable for onset emergency settings, but has proven itself in the past 8 years (see previously attached or here online) in both rural and urbain settings. There are also many local micro-entrepreneurs in the country capable of producing these filters.
One aspect that should be considered in a HWT strategy is the treatment against protozoan oocysts (such as cryptosporidium – which, I heard, was in PaP) which can be illuminated by proper filtration but not by standard chlorination.
In the rural household context, the filters cost about $35-55 (all overhead and follow-up costs included). There is no operation or maintenance costs.. The expected lifetime of the filter is 20 years.. (the oldest operating ones I have seen so far is 8 years).
Here are some technical factsheets or some HWT technologies which could also help in the initial discussion of the HWT sub-group:

Here is a list of ‘competent’ organizations in Haiti (on the biosand filter):
PAIDEH (Thomas Saint-Louis, Directeur des Operations) – Artibonite, Nord, Nord-Ouest - pai...@hotmail.com
ACTED (Fanny Decroux, Country Director) – travaillant avec PAIDEH - fanny.d...@acted.org
Pure Water for Haiti (Jean Succar, Executive Director) – Cite Soleil - jean....@purewaterfortheworld.org
Clean Water for Haiti (Chris Rollings, Executive Director) – St Marc, Artibonite : chrisr...@chrisrolling.com
Other organisations who had implemented filters in Haiti – currently or in the past (qualite not verified by CAWST) :
Do not hesitate to contact me for more information.
I will next be in Haiti from the 18th mai to 9th Juin.
Kind regards,
Olivier
