Raven CASE STUDY - Salt Gradient Solar Pond Project



Liner for Distilling Large Ponds of Brine Water to Fresh Potable Water


Site: Solar Power & Water®

Location: Wellton, AZ

Project Application: Salt Gradient Solar Pond Containment

Project Challenges
  • Sandy soil sub-grade - Dry dusty jobsite that required daily wetting and rolling
  • High temperatures - Temperatures in the region during June can reach 115° Fahrenheit
  • High winds – Large RPP panels required immediate securing following deployment and installment
  • Hot Liquid Containment – The hot brine water in the pond being distilled part of the design consideration
Project Details
  • 45 Mil black Dura-Skrim® NQ-Series Reinforced Polypropylene (RPP) – 2,750,000 Sq. Ft.
  • Manufactured By: Raven Engineered Films – Quality Prefabricated Factory Panels 220’ x 95.94’, Installation by Raven CLI Construction
  • 8 oz Nonwoven Geotextile GTEX8 material for slope underlayment – 360,000 Sq. Ft.
  • 540 Fabricated 36 Mil RPP Ballast Tubes for bench installation area
Project Overview

Fresh water supplies are a world-wide issue for many areas in relation to access and availability. Geosynthetics have long been a significant factor in environmental water containment solutions. Solar Power&Water® pond systems are designed and marketed to address fresh water shortages, agricultural drainage cleanup, and the need for low cost renewable energy. The project scope included a salt gradient solar pond containing a flexible geosynthetic liner system, and with the help of a prime mover (engine), was designed to extract power directly from the pond’s hot brine...
