Old Pinery Camp Water Distribution System

Senior Capstone


Problem

Problem

  • 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.


Tank design

Tank Design

  • 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.


Pipe design

Pipe Design

  • 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.


Final flowrates

Final Flowrates


Water treatment design

Water Treatment Design

  • 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.

    • ASOLITAX sc Turbidity Analyzer with a sc200 controller.

  • 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.


Cost analysis

CostAnalysis

  • 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:


Total cost

Total Cost

  • Two 25,000 gallon tanks at: $39,981.00

  • UV Filter at:$300.00

  • 6 inch pipe (1200 ft.):$5007.00

  • 4 inch pipe ( 4900 ft.):$9530.50

  • 3 inch pipe (50 ft.):$58.81

  • Total Cost Estimate:$94,858.31


Additional recommendations

Additional Recommendations

  • Consider eliminating station 1. The pressures are lower than the 40 psi needed per Utah State Standards and the water spout appears to be removed from the rest of the campsite.

  • Spring loaded faucet heads. This would help to conserve water. The tanks are designed to be able to sustain the camp for the whole summer but during years of low rainfall and streamflowthere could be problems if water is wasted.


Final design

Final Design

  • Two 25,000 gallon tanks that could be placed side by side.

  • 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.

  • UV water treatment and monitor that sends periodic updates about the treatment of the water.
