The designed system were based on Gufu Village in India. The designs consisted solar-powered pumps that draws water from a well half a kilometer outside the village and pumps it through a transmission line to the village, then through a three-tiered system of pipes to each house. Lengths of tubing at each house restricted the flow rate and ensured equity, so that no house would receive significantly more water than any other house. Past team also came up with Mathcad code that sizes a PV array and optimizes pipe and tubing sizes based on equity constraints, local weather data, desired flow rate, and system cost. At the conclusion of the semester, the teams passed on two major challenges. One is increasing system design's affordability by replacing elevated storage tank. The other is providing equitable distribution of water without meters. |
Current & Future Research
In the end of December 2013, The World Bank and Indian Government have launched $1billion rural water and sanitation project for low income states. The onset of the project signified the fundamental need for different approaches in designing water supply system for small villages.
Fall 2014 Village Supply System team is divided into three sub teams: Distribution System Design, Household Infrastructure, and Pump Design. Based on what CEE 4540 Fall 2013 teams have explored, each sub team aims to come up with more applicable village supply system that shall meet the expectation of the World Bank and the Indian government's rural water and sanitation project for low income states. In order to reflect the need of Indian villages, the team will actively have conversation with our partners in India about the growth and equity targets. Also, the team will utilize resource inventories such Google Earth to incorporate objective data of the area.
The challenges of each sub-team are presented below:
Distribution System Design:
Keeping four core standards–cost, efficiency, equity, and convenience–in mind, the Distribution System Design team will create a generalized algorithm for supplying treated ground water to each household. The team will try to ensure to devise flexible algorithm that can easily adjust to changes in population and climate. Three main components of the design shall be pipe sizes, pressure target, and flow restriction.
