Project: Aqueduct Design

We're ready to go! The Water Committee of Quebrada Mina has finished the final phase of planning and surveying, so we're ready to write proposals and look for some funds.

Over the last 13 months, the committee has been meeting with me and poco-a-poco gearing up to construct a water system that will provide for 23 families. Qda. Mina isn't far from my Calabazalian's, so it has been easy to visit them and plan out how we can bring water to this little Ngabe village.

The final surveying of the area has just taken place: several days were needed to measure everything. For instance, a full day was needed to measure the path of the water lines from the springs to the potential tank area; another day was needed for the primary main line while another was needed for the second main line branch; even more time was needed to figure out how we can get PVC tubes to run up and down and around a sizeable hill... hmmm, by now it's already December... I'm glad the survey is finally done!
(Here's the view after crossing over the hill, the "Problem Hill" that is causing us to talk about shared "plumas" for three of the nearby families. In this view, you can see a clearing in the middle ground, that's where the final house lies: down, around, and up the rise.)

There were several volunteers that stopped by to help the surveying go smoothly. Jess Mehl COS 2008 and Steve Russo G60 helped out early on and got things going (and debated with me the merits of an Abney level vs. Water level - no winner yet!). Later, Kaitlin Green joined me for a day walking with Miguel Mora and a small team, yes, still using the Water level.

Eventually I did use the Abney level to re-measure the primary main line. This was important to get an idea of how much error we are really dealing with in elevation. The large hill toward the end of one of the lines is just too high for comfort, so I was careful about the numbers.

Ultimately, I decided not to cross directly over the summit. We can reroute around the lower flank and reach the final cluster of houses but this means 3 families will need to walk 2 minutes down to a shared pluma. It will be interesting to see how they work this into their lifestyles - currently they hike 5 minutes to a "pozo" that dribbles water below a sharp, slippery drop below the homes. I hope they will see the new design as an improvement!

Thanks for providing the photographic evidence KK! These photos were taken in September '08 while the "aspirante" visited for a week. For sure, I wasn't the only one thrilled to have some one new to talk to :)
