Eight Cisterns in Eight Weeks | Salitrillo Cistern Project

Wrapping Up   - 22nd Sept 2016

The cistern project in Salitrillo is well and truly underway. The Pilot cistern at the home of Señora Cecilia Luna Rosas is finished except for a curing period to set the concrete. 

Meanwhile the second cistern of eight which make up the first phase of the Salitrillo project is just about ready for its “gorro” or roof. At this point, the build team of seven women and two men are on their own except for weekly visits from Señor Abel, the technical advisor from CEDESA.

This year the Rotary San Miguel Midday Club working with the Rotary Action Group for Water and Sanitation (WASRAG) introduced an innovation in the cistern construction process: plastic wrap! 

As with any ferro-cement structure, cement must be allowed to cure slowly to prevent cracking and to attain its maximum structural strength. Normally ferro-cement structures are “watered”, sprayed down with water on a daily basis, for a period of days or weeks to make sure that the cement sets up slowly and remains crack-free. 

Needless to say this involves both careful attention to the watering schedule and the use of water which is then wasted. 

Hence, the use of plastic wrap. By wrapping the entire structure in a double layer of industrial sized plastic wrap (think kitchen plastic wrap on a grand scale), the cisterns wall and roof can undergo a slow curing period with much less care and feeding, and with virtually no wasted water.

Though it may seem modest, it’s important to place Salitrillo’s cistern project in perspective. The eight Salitrillo cisterns are among a total of 819 cisterns constructed since 2008. Each cistern collects 12,000 liters of rainwater when full. If you do the math, CEDESA and COCIRA, Project Beneficiaries and Rotary San Miguel Midday have created an amazing above ground reservoir capable of holding a whopping 9,828,000 liters of potable water storage. 

Think about that for a minute. 10 million liters is approximately 3 million gallons or roughly four Olympic sized swimming pools of water captured each year for the drinking and cooking needs of people living within the area of the Independencia aquifer.

When the current Global Grant is completed in the spring of 2017, a total of 1,092 cisterns will have been built representing an investment of over $10,000,000 pesos ($550,000 USD). Total rainwater collection capacity will top 13 million liters. And the geographic area serviced by the combined Rotary projects will include the communities surrounding San Miguel de Allende, San Diego de la Union, Dolores Hidalgo and San Luis de la Paz.

Ready for a Top Hat: Salitrillo Cistern Project

Day Three - 16th September 2016

It’s been two days since my last visit and I can’t believe the progress the build team has made. Not only has the concrete base of the cistern been set, but the walls of the cistern are up, and the metal work for the “gorro” or cap is laid out on the ground.

At this stage, you can see just how massive the finished cistern will be. Four workers are busy inside the cylinder applying the next-to-last coat of concrete. 

Cement is applied first in one direction (horizontal), then after a short period for layer-one cement to set up, a second layer is overlaid in the opposite direction (vertical). 

The bidirectional application makes for tough and water-tight walls. I am amazed to learn that, when full, the walls flex. Okay, the walls don’t actually bulge, but the ferro-cement expands dynamically under the weight of the water.

The “masa” or concrete mud for the gorro is mixed at a ratio of four parts cement to one-part sand, and significantly stiffer than the walls because the wet mix is applied directly to the metal mesh without the aid of plywood backing.

The gorro is equipped with an access door to permit maintenance on the interior of the cistern. 

And the exterior of the cistern is fitted with a clever, but commonsense water level gauge. A clear plastic hose will be connected between the water spigot at the bottom of the cistern and a narrow diameter pipe protruding from the top of the cistern. As the interior water level is drawn down, there is a corresponding drop in the water level in the transparent hose.

Recommended cistern maintenance consists of two primary elements: 1) yearly brushing of interior walls, and 2) if the catchment roof surface is of any material other than concrete or tin, then it must be repainted annually. 

Next stop, the final finish work.

Launched! Salitrillo Cistern Project

Day One - 13th September 2016

When Lee Carter and I arrive, the Salitrillo cistern build team had already laid out a base layer of chicken wire. As a first-time visitor to a cistern pilot, I’m excited to learn the basics of ferro-cement cistern construction.

Once completed, the cistern will hold 12,000 liters, harvesting enough water during one rainy season to serve all of the potable water needs, both drinking and cooking, for a family of 6-8 for a year.

It turns out that the metal structural elements of the cistern walls form a kind of layer cake—a layer of chicken wire folded over a layer of heavy-gauge iron mesh, then covered with a second layer of chicken wire all woven neatly together. Or rather, a layer cake that rolls up into a cylinder to create the walls of the cistern which are then set on a concrete base and lined with a temporary barrier of bendy plywood designed to support the application of an exterior coat of concrete until it dries.

Members of the community are hard at work weaving the chicken wire together under the watchful eye of Señor Abel, a technical expert from CEDESA in charge of teaching community members the basics of cistern construction. 

What stands out for me right away is the ratio of women to men in the work group: most of the team consists of women. And it’s obvious, that the team is already a well-oiled machine. Tasks are carried out with little discussion and a light-hearted atmosphere prevails.

This Salitrillo Pilot is cistern number 48 out of 319 cisterns funded by the Rotary Club’s recent Global Grant (GG1524911) and implemented in collaboration with CEDESA and COCIRA. 

It’s the first cistern for this little community of just 52 families. A total of eight cisterns are planned for Salitrillo. Once the core group is trained, they will cooperate to assist their neighbors with subsequent cisterns. Señor Abel from CEDESA will then make weekly visits to monitor progress and ensure quality-control.

Nombre de Dios Cistern Project Completion Celebration – August 13, 2016

Approximately 50 people - friends & neighbors - came together today to celebrate the completion of the last of five cisterns. 

The night was full of rain & the road there was sometimes good & sometimes a muddy slip-sliding mess, but a 90 minute drive got us there. The day was overcast with a breeze & chairs were set up in a large circle under a large Mesquite tree. The view to the west to get to Guanajuato was beautiful. Everything green from recent rains. The cisterns already had 2 feet of water.

After thanks to the people coming, CEDESA, COCIRA, & Rotary Club Midday, the people all held hands & gave (one at a time) thanks. Some took longer but you were allowed to pass the “prayer” to the next person. 

The nice thing about travelling is seeing how people are the same but different. This prayer circle was a perfect example. They all held hands left under and right over. After “prayer” we all went to three cisterns close by & had ribbon cutting with the owners. 

One elderly woman, instead of materials for a cistern, received a tinaco (large plastic container) because she would not be able to do the work of building a cistern. 

Lunch was a potluck type where all families come together with rice, tortilla, mole, beans, macaroni & ham, beef, horchata (a rice drink with cinnamon), & pineapple water.

Lee Carter, Nate Fultz, Beatriz Salcedo from Rotary attended as did Carla Cadena, intern/administrator of GG1524911.

Project Update July 23, 2016

The project (1624911) has been moving along at break neck speed!

We have now presented the education program 3 times: Boca de la Cañada, Charco de Araujo, La Colorada. 

This week I went with Ceci (CEDESA) to observe the final day of the program in La Colorada. Universally the beneficiaries are finding the program both helpful & also very fun. A number of people told me that they thought spending three days in water education was going to be boring & too much time. However, after experiencing the program, they are all very excited & relate that they understand much better now the water problems of the region & why the cisterns are so important. 

We are administering a Pre-education questionnaire & a Post-education questionnaire so that we can measure the success of the education program. I look forward to reporting those results at a later date.

We have cisterns under construction in Charco de Araujo (14 cisterns & 3 tinacos), La Colorada (24), & Boca de la Cañada (21) now. 

We have used all of the special caliber chicken wire from our vendor, Hierro Comercial, & are now waiting for it to be re-stocked. It is a special factory order & will take from four to six weeks to be restocked. This is OK as we are at a point that we need to review our progress to date & take care of many details. 

We hope to have the final version of the Water Education Manual finished & ready to go to the printer late next week. We are moving forward on the second draft of the Cistern Construction & Maintenance Manual next week. 

We still have not found a suitable truck for CEDESA & without it, getting CEDESA promotors & technicians to the project sites has been a challenge. With this respite in construction, I hope we can get these important details completed in the next few weeks. 

Next Thursday we will have a planning meeting at CEDESA to reschedule the project details & resolve questions about the next phases of the project.

Lee Carter - Rotary San Miguel Midday

Charco de Araujo, San Diego de la Union June 21 to June 23, 2016

After many meetings & lots of hard work on the part of CEDESA, COCIRA, UCCANG & Rotary under the guiding hands of Wendy Coulson; our expert in curriculum & adult teaching methods, the first five modules of the education program were presented in Charco de Araujo. 

The program is very hands-on & participatory so it is much more than just a presentation.

There was much enthusiasm among the participants with several persons proclaiming that EVERY person in the community should have an opportunity to learn all of this!

Overall, we are very pleased. We are now teaching at Boca de la Cañada in San Miguel & next week Wendy & I will meet to review & talk about revisions to the curriculum & also the manual which is in its "almost final draft" form. 

I will let the photos tell the story. Enjoy - Lee

A Day at CEDESA

May 19, 2016

Yesterday, after going to Nombre de Dios with Chela and Abel, we returned to CEDESA for additional planning of our new global grant (GG1524911) for 319 more water harvesting cisterns in San Miguel, Dolores Hidalgo, San Diego de la Union & San Luis de la Paz. 

Present were Chela, Abel, Meche, Benigno, and Ceci.

We reviewed first the progress on the new education program & the principal objectives of that program. Meche has been working hard with Wendy Coulson to develop the program & didactic materials to go with that. We all agreed that in a nutshell our goals are to have people fully understand

1.       the reason for cisterns is lack of an improved water source or having water that is terribly contaminated with fluoride and arsenic.

2.      the cistern water is free from those poisons & they should never drink water from wells.

3.        they can improve their water & health even more by integrating disinfection steps to improve the cistern water & avoid any potential biological contamination &

4.       have people learn how to self-construct their water harvesting system & maintain it to get maximum benefit from it.

Those are our primary objectives for this project &grant. However we also will be using this opportunity to continue to develop the communities' capacity to work together to analyze their problems & seek solutions (resources). 

We'd like to build on this opportunity so that they can take advantage of other opportunities such as backyard gardens, natural medicine, beekeeping, & other eco-technologies such as gray water filtering & the eco-cina stoves. We'd like the cistern projects to continue to be the first step in the long process of community empowerment.

The education program is ready now to “beta test” in the first communities. We are going to start in Boca de la Cañada (San Miguel) in two weeks & then in Las Claveles (Dolores) after that. 

We will present the didactic materials in the “final draft” format & then make adjustments before going to press & printing enough materials to carry us through the project.

Everyone in the communities are enthusiastic & champing at the bit to get started. They all want to work through the summer rainy season in order to be able to harvest at least a little rain before the dry weather returns in the fall. 

CEDESA is going to work up a draft schedule next week so we can plan out each mini-project. They are talking about doing as many as four different communities per month. Yikes, that is going to be a lot of work for all of us!

As we worked through potential pitfalls & bottlenecks in this ambitious program, we realized that we would need another technician in addition to Benigno & Abel to be able to do the site visits in each community during the construction process. 

A great solution was devised that will also allow us to continue to develop our youth program in the process. We will select a young person in each community where we are working to become an expert in construction & maintenance of the systems. This person will do the project monitoring throughout the construction process & will be report & consult with Abel &/or Benigno as the mini-project proceeds. Instead of having a once a week visit from the technician, we will have someone there overseeing the construction on a daily basis as each group builds cisterns at each home. 

Once the project is complete we will be leaving behind “a community expert” who can continue to monitor cisterns & even assist in repairs as needed. We already have a budget for an albanil for the pilot week. Since each group is now obligated to provide an albanil throughout the mini-project including the pilot cistern week, those funds can be used as a stipend for developing our new community expert. CEDESA will be responsible for handling the payment process.

We also reviewed the financial resources available in the grant so that we could come up with a simplified billing plan. When we combine our organization budget with our education teaching budget, we have 2,400 pesos for Pre-Pilot expenses. For the Pilot stage of the project we have $4,750 in funds available. And for post-project monitoring & evaluation we have 900 pesos available. 

We budgeted for 11 mini-projects as we were developing the project but as the number of cisterns grew the number of mini-projects is likely to be 15 to 18 … thank heavens for our contingency budget!

CEDESA is to be responsible for tracking certain costs/expenses each month & reporting them to Rotary for reimbursement. They need to record all KM driven in CEDESA vehicles in executing the projects to be reimbursed @ 3.5 pesos / KM. They also need to keep all tickets from using public transportation so that can be reimbursed as well up to a total of $9000 for the project. We will also be providing an $800 peso phone allowance per month to be split up between the various promotors & technicians.

Equipment: We need to get the new vehicle as soon as possible. Rotary has $5,000 dollars to contribute to that. CEDESA has 30,000 pesos set aside as well. We are going to purchase one “very good” vehicle that will last many years into the future for project monitoring. We are going to invest about 10,000 pesos of that money in upgrading an existing vehicle. Even with two new vehicles in play, transportation will still be a headache for CEDESA. 

The electrode in the fluoride testing laboratory has failed & we are looking into replacing that. Initial quotations that Meche got are expensive … about US$1,500. We had not counted on needing this within the time frame of this grant. We will probably reduce our “tools” budget to get this back on-line &I will try to see if we can find outside resources to help cover this unexpected expense.

We are working to be able to get the communities on the edges of San Diego de la Union & San Luis de la Paz involved in this grant. To do so, the two “subgroups” will have to work under UCCANG. 

UCCANG is responsible for carrying out several functions … community selection, receiving solicitudes & for providing monitoring and evaluation for six months after the construction phase. Integrating them into UCCANG does not seem to be a problem. The two subgroups are SECOPA (Servicios Comunitarios de Pozos Ademada – San Diego Union) and CUVA (Comunidades Unidas Para La Vida y Agua – San Jose Iturbide).

Recently a well in the San Jose Iturbide area, in the community of La Cantera, was discovered to have radioactivity in the water. There has been a high rate of documented child leukemia in that town as well. Dr. Ortega of UNAM is studying the problem to determine if this is an isolated instance of industrial contamination or if it is going to be as a result of the ever-challenging problems we are facing in the aquifer. There are 120 affected families & the government is, of course, denying that there is a problem.
