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.

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.

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.

Cost 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. A price quote was also obtained for the needed pipe sizes. All the cost breakdowns can be seen in the following tables: Pipe Size Price from Xerxes 6 inch $ inch $ inch$58.81
