John traveled to Mercedes last week to follow up on the installation of chlorine flow controllers there. Together with several APP technicians and an engineer, we installed three flow controllers. After these installations, the APP technicians in Mercedes are well prepared to continue installing controllers on their own. We also visited Limoncito and Miraflores, two commnuities where Antonio and Tamar had installed flow controllers in August. Miraflores had run out of chlorine and was in the process of buying more. In Limoncito, the flow controller was functioning and there was 1.0 mg/L of chlorine residual in the distribution tank. The doser hose was partially clogged with chlorine sediment, reducing the flow from the controller. We suggested that the opperator clean the hose with vinegar.

John left 10 more flow control modules, to be installed in other communities. We still need to provide the community with 3 more, but will be unable to do so until we find connectors that don't leak. The municipality is purchasing the flow controllers for about $45 each from APP with funds from the project DESCEAS.
