Introduction • Water supply system • Nong Pit, Thailand • Data Analysis • Design Options • • • Gravity Fed System Turbine/Pump Distribution System
Problem • During Dry Season, Inadequate Water Supply • February - April • 760 People, 216 Households • Water Source Location
Initial Data • Surveying data from assessment trip • Lengths of trails = 1881 meters • Change in elevations = 2. 51 meters • Cross sections of stream • Volume = 64. 56 m 3 • Factor of Safety of 0. 2
Calculations
Calculations • Cross Sectional Area • Determination of Flow at elevations

Future Design • Centrifugal Pumps • Different Horsepower • Pump Head Curves (PHC) • Compare SHC and PHC • Find operating point • • Flow: time to fill tanks Energy: amount added
Future Design • Turbine • Determine energy generated using waterfall • Choose Pump • Turbine energy • Energy needed to power pump • Energy added to the system time to fill tanks
Design Option: Distribution System
Specifications • Water. Sense Lavatory Faucet Based on EPA product industry and ASME • Maximum • • 0. 000095 m 3/s 0. 0853 kg/m 2 Minimum • • 0. 00005 m 3/s 0. 02844 kg/m 2
Future Design
Future Design • Types of Systems • Looped System • • • Lower Velocity, lower Head Loss, greater Capacity More costly Branched System • • Faster Velocity, greater Head Loss, reduced Capacity Lower costs
Future Design • Layout of Village • Assumed • Rough sketch from Thailand • Pipe Sizes • Each outlet meets flow and pressure requirements • Systems must have internally consistent distribution of flows • Flow entering must equal flow exiting
Budget • Fundraising • SBA: $600 • Applebees: $200 • T-Shirt: $400 • Flower Sale: $1, 000+ • Estimated Spending • Pipes • Tanks • Turbine/Pump • Travel
Timeline
Conclusion • Village with Insufficient Water Supply • Analyzed Data for 3 Designs Gravity Fed System • Turbine/Pump • Distribution to Village • • Proposed Implementation Summer 2012
