               Engineering as a tool for improving human habitat (Int. J. Management and Decision Making,
               2009) – Quote: The concept of Slum Networking proposes comprehensive water
               and environmental sanitation infrastructure as the central and catalytic
               leverage for holistic development. At costs less than the conventional ‘slum’
               solutions, it tries to penetrate a high quality urban infrastructure net deeply
               into the slums to assimilate them into the city rather than lock them in as
               disadvantaged islands.

     Appropriate Design Standards and Construction Specifications for Tertiary Sewerage Systems
     [Faisalabad, Pakistan] (GHK, 2002) − in this publication settled sewerage is
      recommended: “Solids traps and interceptor tanks on household connections
      are therefore an integral component of the recommended design for tertiary
      sewerage systems” (pdf page 28) − interceptor tank design is given on pdf
      pages 41−43.

     (Foundation for Greentech Environmental Systems, 2008) − reported costs are one third
     of those for conventional sewerage.
     Note: simplified and settled sewerage are at least mentioned in the Indian 
     Sewerage and Sewage Treatment Manual (2nd ed., Ministry of Urban Develop-
