Brackish Stream Treatment Plan

Possum Engineering presents a comprehensive treatment plan for a brackish stream in a backyard setting. The project, led by Josh Ogle, Meg Przybyla, Kyle Smith, and Alex Stodtmeister, includes GPS mapping, water quality analysis, and capacity assessments. Various options were explored, including heat exchange systems and water purification methods, with estimated costs and returns on investment discussed. Final recommendations prioritize a ground heat exchange system to enhance sustainability while reducing energy costs effectively.

  1. Brackish Stream Treatment Plan Possum Engineering: Josh Ogle Meg Przybyla Kyle Smith Alex Stodtmeister 12 April 2013

  2. Problem • Brackish Stream running backyard • Desire to “go green” and make use of stream • Possum Engineering chosen to explore the option and choose the most viable option Possum Engineering

  3. Field Work • GPS Mapping of Dr. Chandler’s Property • Water Quality Analysis • Water Capacity Analysis Possum Engineering

  4. Field Work - GPS Mapping Possum Engineering

  5. Results - GPS Mapping Possum Engineering

  6. Field Work - Water Quality Analysis Possum Engineering

  7. Field Work - Water Quality Analysis • On-site analysis with water quality sondes • Dissolved oxygen, specific conductivity, temperature, pH, chlorophyll • Samples taken for further testing at BYU • Total solids, total suspended & volatile solids • Chemical oxygen demand • Metal concentrations Possum Engineering

  8. Results – On-site Analysis Possum Engineering

  9. Results – Solids and COD Possum Engineering

  10. Results - ICP Possum Engineering

  11. Results – Water Chemistry Possum Engineering

  12. Slingshot Option • 264.2 gallons of water/day Cost - $100,000 Possum Engineering

  13. Heat Exchange Option • 15,000 linear feet of pipe lay coiled 10 feet underground in horizontal slinky loop • Paxman Heating installed Dr. Astle’s system Cost - $20,000 ROI - $1,200/year (Cutting Power Bill by 42-50%) Possum Engineering

  14. Water Purification Option COST ≈ $500 COST ≈ $14,250 COST ≈ $250 Total Cost ≈ $15,500 ROI ≈ $420/year (If 50% of monthly water use provided by RO System) Possum Engineering

  15. Legal Constraints • After receiving all Water Users' Claims, the State Engineer then prepares a proposed determination of water rights of all water users in the drainage or sub-drainage that is served on water users and filed in court Possum Engineering

  16. Final Recommendation • Ground Heat Exchange System Benefits: • Cut Power Bill in half Investment Cost: • $20,000 Return on Investment: • $1,200 per year • Pay for itself in 16 years Possum Engineering

  17. Acknowledgements • Dr. Mike Chandler • Dr. Gus Williams • Dr. Jim Nelson • Dr. Wood Miller • Dr. Craig Astle • Craig Hammer • Paxman Heating • Jay Sandberg, P.E. • Phil Stewart • Zola Adjei Possum Engineering
