Table of Contents:
  • Introduction to on-site and decentralized wastewater treatment and typical components of DEWATS systems. Discusses pre-treatment, primary treatment, secondary treatment, disinfection, reuse and recycling
  • The DEWATS decision model
  • critical inputs (source and site) and the DEWATS decision-making process
  • Characterizing the Source by determining hydraulic and organic loading
  • Identifying fluctuations in flow, anddentifying other source factors that might impact upon the technology decisions
  • Evaluating the Site: oDrawing the site plan. Includes checklists, setbacks and examples. oDetermining available area for wastewater components
  • oTesting the soils for depth, bearing capacity and permeability. oDiscusses percolation testing and soils evaluation as methods for determining permeability. oChecking the slope and drawing topography oEvaluating water resources
  • groundwater and surface water, and methods for collecting anecdotal information to determine flood plain elevations
  • oUnderstanding the local land-use issues
  • oEvaluating social issues related to the site
  • Using Collected Data for DEWATS Decision-making
