Systematic project planning and appraisal BambrahGurmeet K. 2018 This paper outlines a version of the systematic approach to project planning (SAPP) adapted for water supply projects. An extension of environmental impact analysis, SAPP is a flexible investment planning tool, incorporating global and human contexts, while being comprehensive, multi-disciplinary, integrated and interactive. Based on previous work (Ref 1) by the author, this methodology recognises that sustainable human development is only possible through appropriate planning and investment. A case study based on a major water supply project is used to illustrate the practical application of SAPP.
