Village Supply System - Distribution Subteam – Fall 2014

Maria Veronica Cordova, Tianchen Yu

Abstract:

The Team Village Supply has three sub teams working on the photovoltaic pump, distribution and household design. The Village Supply­Distribution System Subteam has worked based on last semesters code 2canzzzz’ and improved it so that it has more accurate final results and it can be set continuous, meaning that this code can be updated with any characteristics of other villages. The overall design of the subteam consist in the network of pipes that distribute water coming from the tank to every house in the village. The new code has taken into account the flow variation into each tier of pipes, and thus the result in the sizing of the pipes has changed significantly. As a result we obtain the critical path and the correspondent head loss through the pipes, considering major and minor losses and differences in height elevations. The cost of the total network design including pipes and tees has been calculated with updated costs for the optimal solution.

Distribution System Contamination Prevention, Fall 2014

Alicia Peters, Chen Weier, David Gold, Lucia Garcia-Iturri Gallego

Abstract

Contamination of treated water in the distribution system has the potential to negate the improvements to water quality provided by an AguaClara plant. Intermittent distribution systems may create the conditions for the mechanisms which cause this contamination to occur. The most likely mechanisms of distribution system contamination are pipeline intrusion, cross contamination and inadequate household storage. Through proper operator training, effective regulation and installation of secure storage facilities and backflow prevention valves, these mechanisms can be prevented and safe water delivered to all AguaClara households.
