Merchandise Description
S.M. Parten (2010)

Covering technical principles and practical applications, this comprehensive resource explains how to design and construct sound and sustainable decentralized wastewater systems of varying sizes and in different geophysical conditions. This book covers state-of-the-art techniques, materials, and industry practices, and provides detailed explanations for why certain approaches result in more sustainable projects. A rational approach is presented for assessing assimilative capacities of soils, and selecting methods of wastewater treatment and dispersal that make optimal use of natural treatment processes and site conditions.

In-depth design and construction information highlights nonproprietary methods proven to be very sustainable and cost effective on a long-term basis for many geographic settings. Step-by-step illustrations and project examples featuring real-world implementations of onsite wastewater systems are included in this definitive volume.

This book covers:
  • sustainability factors and planning considerations for decentralized wastewater systems,
  • project planning and site evaluation,
  • wastewater collection and conveyance methods,
  • design and installation of primary treatment units,
  • comparisons of secondary and advanced treatment methods,
  • sand filter construction,
  • subsurface flow wetland performance and construction,
  • effluent dispersal methods, and
  • design and installation of low-pressure dosed effluent dispersal systems.
412 pages, hardback.
