SOARES, Sérgio R. A.; BERNARDES, Ricardo S.  and  CORDEIRO NETTO, Oscar de M.. Relationship between water supply, sanitation, public health, and environment: elements for the formulation of a sanitary infrastructure planning model. Cad. Saúde Pública [online]. 2002, vol.18, n.6, pp.1713-1724. ISSN 1678-4464.

The understanding of sanitation infrastructure, public health, and environmental relations is a fundamental assumption for planning sanitation infrastructure in urban areas. This article thus suggests elements for developing a planning model for sanitation infrastructure. The authors performed a historical survey of environmental and public health issues related to the sector, an analysis of the conceptual frameworks involving public health and sanitation systems, and a systematization of the various effects that water supply and sanitation have on public health and the environment. Evaluation of these effects should guarantee the correct analysis of possible alternatives, deal with environmental and public health objectives (the main purpose of sanitation infrastructure), and provide the most reasonable indication of actions. The suggested systematization of the sanitation systems effects in each step of their implementation is an advance considering the association between the fundamental elements for formulating a planning model for sanitation infrastructure.
