Cuatro Comunidades

Tuesday 2.10, we finalized all the measurements in the sedimentation tanks and discussed the floc weir. We gave measurements for the plaques that will control the flow into the sedimentation tanks coming from the channel. We also decided where the pipes coming from the entrance tank would lead into the bathroom.
The molds for the 'plaque supports' which refer to the lining on the bottom of the sedimentation tanks which support the plaques and also serve to drain the tanks have been completed. Below is a picture of the 'plaque supports.'

Wednesday 2.11 and Thursday 2.12 Antonio worked with Gustavo and Justo, two potential operators from the community to assemble the lamella in the sedimentation tanks. We decided for the next plant it might be worth the cost to have the lamella cut professionally to have a more elegant looking final product.

Friday 2.13 eight plaques were complete that we tested inside the sedimentation tanks to finalize the dimensions of the floc weir. We decided to extend the pipe for draining the sedimentation tank to begin at the same point where the floc weir hits the bottom of the sedimentation tank. We will then condition the pipe (with heat) to fit underneath the supports for the plaques. Since the plaque supports form a rectangular shape with the bottom of the tanks, we will need to condition the circular pipe to fit inside.

A top view of the channel which drains into the sedimentation tanks can be seen below.

Next week they will be working on making the 'drain channel' - where the flocculation and sedimentation tanks drain into. You can see below all the pipes that drain into the tank. The sedimentation tank has three pipes: to clean off the surface of the sed tanks, to drain the floc blanket, and to drain the entire tank.

Documentation of AguaClara Performance

On Friday 2.13. John and Tamar worked on the documentation study. We hope to have Arturo and Jacobo revise the study to then formalize another meeting with SANAA.

CCC Study

On Tuesday 2.13 we met with Lizera Polanco Barahona, Mirna Argueta and Oscar Membreno of SANAA to discuss the terms of the CCC study. SANAA agreed to provide the technicians to monitor the CCC's in the communities that we will use for the study. SANAA has chosen 5 communities for the study (3 that will have the CCC installed, and 2 that will serve as a contol) in an area that SANAA currently has budgeting for.
Antonio will give an introduction to the study next Monday 2.23 to SANAA technicians and a more formal presentation on how the CCC's operate on 3.2.09. Antonio will make the contacts with the Junta's of these communities to evaluate their interest in this project. The Junta will be responsible for monitoring the pH, turbidity and chlorine residual.

Publicity

John and Tamar worked on making a general presentation about the AguaClara plants to be used to send to other NGO's and organizations that are currently working in the water sector.
