Next week we hope to start work on the fabrication of sed tank lamella modules. Justo, one of the potential plant operators, will participate in order to become familiar with the process.

Guaimaca
Tuesday 2.03, Wil and John went to Guaimaca to better assess where the city's two treatment plants could be located. Because of the size of Guimaca and the investment involved in constructing the AguaClara plant, we think it is important to leave enough elevation between the plant and the tanks to be able to add filters in the future.
Tank #1 is partially buried in the ground, so that the maximum water level is only about 1.8 m above the surrounding ground. Building up the land about a meter, and with a 2.8 m deep plant, we think 2 m of elevation could still be left between the plant and the tank for the construction of filters.
The site at Tank #2 is more problematic. The tank is located on the point of a hill, and there is no higher ground nearby. One option would be to divert the 8" conduction line to higher ground 400m away and across the main highway. The water would then have to be piped back to the existing tank. Another option would be to build a retaining wall next to the hill and fill in the land to build the plant right next to the tank. A third option we discussed was to build a new tank on a nearby lower hill and build the plant in the location of the current tank. The current tank is only about 12 years old but was poorly built and is not in very good condition. The base and perhaps some of the walls of the current tank could be used for the treatment plant. All three of these options imply added costs, which would have to be calculated to decide which option is more practical.
We also collected the turbidity data the public works manager had been taken. It showed that both of Guimaca's sources have significant and similar turbidity, meaning that two treatment plants are necessary.
We left preliminary plans and a budget with the vice mayor and are hoping to meet with the mayor soon to discuss the possibilities of a project.
