Our code sizes a PV array and optimizes pipe and tubing sizes based on equity constraints, local weather data, desired flow rate, and system cost.
Household Infrastructure Subteam:
This semester, goals of the house hold infrastructure sub team include designing a household water storage tank, including a float valve and a flow restriction valve to ensure equitable distribution of water. Additionally this team will be designing a tap or faucet system for individual house holds that minimizes water contamination, the spread of waste and encourages sanitary habits. This team will also consider the design of a sink or water catch system for recycling and disposing of grey water.
In future semesters, this team could include anything from redesign of the toilet (use less or no water) to design of a greywater treatment system that will allow households to repurpose their wastewater safely. The code will also need to be modified to account for growth and variability, ensuring that the system can adapt to any rural village.
Pump Design Subteam:
This section works on how to modify and improves upon the ideas and models already in place for design of pumps in villages for the Fall 2014 Semester. Specific goals for these pumps include: having single electric pumps that send water to the town and lifts water from the well at ground level to an AguaClara facility/distribution system, deliberating types of pumps and pressure requirements for equal distribution, balancing cost and efficiency of pumps, and evaluating the different options for the design of the photovoltaic and pump system.
Among the different designs for the photovoltaic and pump system, this section will be looking at two main options. The first option will be to divide the power between the two pumps, create a simple control system for easily maintenance, and to design the photovoltaic system to be able to handle cloudy, winter days. The second option to be looked into will be to divert all the power to the first pump on cloudy days and to allow the control system to automatically divert all of the power to the well pump when the chlorine contact tank isn't full—thereby allowing the second option to be more easily implemented.
