Covers currently available advanced onsite wastewater system technologies
Presents details on two of the most commonly used advanced onsite wastewater treatment technologies - Media Filters and Aerobic Treatment Units
Explores new concepts on how onsite systems should be regulated so that professionals can select, install, and use an appropriate system
Contains information on how to fix failing septic tank systems, whether 30-plus years old or recently installed
Provides tables and computer spreadsheets to be used in calculations for selecting and approving onsite wastewater systems
Includes access to a supporting Web site that provides spreadsheets and ancillary details on projects described in the book
Drawing on the authors' combined experience of more than 30 years, Advanced Onsite Wastewater Systems Technologies explores use of these technologies on a wide-scale basis to solve the problems associated with conventional septic tank and drain field systems. The authors discuss a regulatory and management infrastructure for ensuring long-term, reliable applications of onsite systems for wastewater management. The book and its supporting web-site (www.advancedonsitesystems.com) are an information catalog for advanced onsite wastewater technologies. This combination offers tools that will help onsite wastewater professionals communicate effectively with each other and their clients, thus minimizing the confusion and misunderstandings often related to the use of advanced onsite systems.
The authors provide an overview of advanced onsite systems technologies and compare them to conventional onsite systems and centralized wastewater systems. They present key concepts for decentralized wastewater solutions and information on advanced onsite wastewater treatment and effluent dispersal technologies currently available. The book delineates a management, regulatory, and planning framework for adopting the use of advanced onsite systems technologies as alternatives to conventional septic systems and centralized collection and treatment plants. It concludes with an exploration of the future of advanced onsite systems technologies and their uses.
A toolbox for service professionals, regulators, and community planners, the book highlights objective methods to assess the performance of technologies and examples of real-world applications. The authors detail a solution-driven and performance-based regulatory framework for the use of advanced onsite systems as a true alternative to centralized collection and treatment plants and offer guidance on how to plan for future growth with such systems. They answer the age-old question of "what to do when the land doesn't perc and sewer isn't coming?"
