Vivienda de Abajo – 12 cisterns project GG1422619 & Amigas de Vivienda

Materials are being supplied by a private group calling themselves “Amigas de Vivienda”. Rotary is financing the education, training and  project management through GG1422619.

Progress at Vivienda is going well. The pilot is finished & now all wrapped up in plastic sheeting to allow the cement to cure at a slower rate which should increase its strength as well as reduce hairline cracking that sometimes takes place with ferro-cement construction. It is an experiment & I am curious to see if it works. Cisterns 2 & 3 are almost complete.

We have put several new innovations into practice with this project:

1. painted the galvanized nipples with Eco-Prim a special material that will allow the cement to adhere to the galvanized.
2. added a more “convenient” first flush mechanism that will likely result in more people using the first flush as a way to divert water from a dirty roof.
3. plan to add a cement pad under the first flush so a tambor (barrel) can be placed there to collect this water for non-cooking & non-drinking uses. The pad will also discourage erosion around the cistern.
4. produced a sizing chart so families will know how much water to divert.
5. improved the door design for ease of installation
6. added mosquito netting to the overflow pipe.
7. will put a cement pad under the spigot to improve cleanliness and reduce chances of bio-contamination.
8. wrapping the cisterns with shrinkwrap.
9. changed from 3 inch PVC to 4 inch PVC for only a $115 peso price increase. This will make gutters capable of carrying more water & make the installation more secure.

Closing Ceremony Vivienda de Abajo

Yesterday we celebrated the completion of 10 cisterns in Vivienda de Abajo. Nine cisterns were in family homes and one was at the secondary school. This is the last cistern that we plan to build in a public space until we have a program in place to ensure maintenance and proper use. The development process for building a “public” cistern that must be maintained by a group or committee is very different than the process of building privately owned cisterns.

Attending were 15 families from Vivienda that are still participating in COCIRA. These persons are involved in other CEDESA promoted projects such as backyard gardening, health clinics & home health training, and bee keeping. Overall there were about 40 persons in attendance and a wonderful lunch (especially wonderful green mole) was served. 

New members to COCIRA seeking Rotary resources were in attendance from Nombre de Dios, San Lorenzo, Boca de Canada and Ex-Hacienda de Pena Blanca.

Chela, Mayra, Saul and Mago were representing CEDESA. Lee Carter was there from Rotary San Miguel Midday. As this was Saul’s last official day as a CEDESA promotor, he cut the inaugural ribbon.

It is interesting to see how some projects go better than others, but I still am not sure how to predict a project’s outcome. This project is one of the best we have had during this grant. All of the cisterns are well constructed, connected and in good service. On the other hand, we still need to go back and do remedial work on about one-half of the cisterns in Banda. I will be talking with CEDESA about sending a technical representative to Banda in the next several weeks to finish up that project so that we finish there with 100% of the collection systems functional and collecting the summer rains. We have determined that having a good and responsible albanil (experienced construction worker) as a part of the work group is very important.
