  • Homepage | The Water Research Foundation
    In the United States alone, billions of gallons of water are treated each day at water resource recovery facilities Once the water is clean, a different challenge remains: determining what to do with the solids that are removed during the treatment process The resulting mixture is often a unique semi-solid blend of organic and inorganic materials, trace elements, chemicals, and even
  • 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
  • WERF CRTC Protocols for Evaluating Secondary Clarifier Performance
    Synthesizes a decade of research on secondary clarifiers Will develop guidelines that treatment facilities can use to evaluate and improve performance Cost savings will be realized through improved efficiency in downstream processes Originally funded as WERF project 00-CTS-1
  • Methods for Wastewater Characterization in Activated Sludge Modeling . . .
    This manual is for users of activated sludge models It provides information on the best methods to measure the wastewater characteristics and kinetic stoichiometric parameters used in activated sludge models The report also provides guidance and examples of how to incorporate these activated sludge models into computer simulations of treatment plant design and operation Applying the methods
  • BMP SELECT Model Version 2. 0 and Users Guide
    SELECT output includes annual pollutant loads discharged to the receiving water, pollutant load frequency curves with uncertainty estimates, and applies WERF’s whole life cost model to enable estimates of system cost
  • Stormwater Thermal Enrichment in Urban Watersheds
    Mounting evidence suggests that stormwater mitigation and treatment approaches targeting only pollutant loading and flow moderation in urbanized, coldwater habitats are not sufficient to achieve overall desired water quality benefits Temperature, as one of the key environmental variables controlling aquatic biota, must also be considered in stormwater management planning where urban runoff is
  • User’s Guide to the WERF BMP Toolkit Framework Version 2. 1
    Stormwater and watershed managers must develop the most cost-effective watershed management plans to reduce specific pollutants to receiving waters in a world of uncertainty about BMP effectiveness and compliance with complex regulations Framework 2 1 links BMP performance for specific pollutants and flow to receiving water loadings, impacts and water quality objectives to improve selection
  • Modeling Guidance for Developing Site-Specific Nutrient Goals
    This research report presents guidance and tools for the use of models to set waterbody-specific nutrient goals, including Numeric Nutrient Criteria (NNC) and allowable nutrient loadings The developed Nutrient Modeling Toolbox contains 30 models capable of quantifying the relationship between nutrient loads and their impacts in terms of water quality or ecological response indicators As of
  • BMP and LID Whole Life Cost Models: Version 2. 0
    A set of spreadsheet tools help users identify and combine capital costs and ongoing maintenance expenditures in order to estimate whole life costs for stormwater management The models provide a framework for calculating capital and long-term maintenance costs of individual best management practices and low impact development techniques Models are included for: retention ponds, extended
  • Institutional Issues for One Water Management
    Governance, regulations, finance, and culture are often cited as barriers to achieving integrated water management and innovation in water technologies This study sought to define those barriers Three in-depth case studies and 25 snapshot case studies provide practical examples of how agencies and communities worked through institutional barriers so they could practice a more integrated and
