Old Pinery Water Distribution System

Old Pinery Water Distribution System JAKEngineering Water Treatment Design Pipe Design Andrew Gwynn Jasmyn Harper Kyle Sumsion • The water will be treated by the system before being stored in the tank. • Two different water treatment options were considered, UV and RO. • Because of the remote location of the camp a monitor will also be set up that records and sends periodic updates about the water treatment and current conditions of the water. • The final design of the treatment system consists of a UV water treatment and monitor that sends periodic updates about the treatment of the water. Task • The existing water distribution system at the Old Pinery Camp has failed and needs to be re-designed. • The tank size needs to be increased so that the camp has sufficient water to last throughout the summer. • The piping will be changed from PVC to Polyethylene. • A new water treatment system will be installed so that the water can be treated before it is stored. Cost Analysis Tank Design/Analysis • Two different manufacturers were considered for the tank design, Darco and Xerxes. A cost analysis of both designs showed that Darco was a better option. • UV was also a much better option with regards to price than RO. • Both comparisons can be seen in the following tables: • Calculated the total length of pipe needed for the system based off of AutoCAD drawings that were provided by the church. • Used Bernoulli’s equation along with Darcy-Weisbach to calculate the losses and velocities in each segment of pipe. • Analyzed a total of four variations of pipe sizing to determine which design was optimal and would result in the necessary flowrates and pressures at the various water spouts. • The final design consisted of 6” polyethylene piping for the upper section, 4” polyethylene piping for the sections after the pipe change, and one small segment of 3” pipe just before the pipe change. • Per Utah State standards, camps must have 20 gallons of water/person/day along with 10 gallons/person/day in storage. • It was assumed that only 200 people would be in the camp at any given time. • Based off of the demands and the streamflow data that was available it was concluded that 50,000 gallons was needed as storage to start the summer. • The final design consisted of two 25,000 gallon tanks that could be placed side by side.
