  • Homepage | The Water Research Foundation
    Climate change is altering our natural hydrologic cycle, creating uncertainty when it comes to the quality and quantity of water sources WRF’s research on climate change covers the key areas of climate risk assessment, climate adaptation, and mitigation strategies Because the first step in preparing for climate change is understanding the potential and variable impacts these changes can
  • Sustainable Infrastructure Management Program Learning Environment . . .
    The Water Research Foundation, in collaboration with the Water Environment Research Foundation (WERF), has expanded the web-based knowledge management system originally built for wastewater utilities (called SIMPLE: Sustainable Infrastructure Management Program Learning Environment) to include information for drinking water utilities
  • Condition Assessment Strategies and Protocols for Water and Wastewater . . .
    Provides utilities with information on how to effectively use condition assessment tools and techniques to improve both long-term planning and day-to-day management of assets The report is structured for two distinct audiences: (1) Utility planning managers who want to embark upon cost-effective condition and performance assessment programs to support long-term planning decisions, and (2
