Environmental assessment for wastewater reclamation and reuse projects

Abstract

The purpose of an environmental review and assessment is to incorporate environmental considerations into the planning process. Prior to the selection of a specific project alternative, a thorough and unbiased analysis of the environmental impacts of every reasonable project alternative should be made. It is intended that environmental concerns be considered on an equal basis with engineering feasibility, economics, and social considerations in wastewater reclamation and reuse. This paper discusses the “procedural” and “substantive” provisions of environmental law in the United States; National Environmental Policy Act (NEPA), and more specifically the law in California; California Environmental Quality Act (CEQA). The procedural aspects require the preparation of an environmental document such as an environmental impact statement (EIS) or an environmental impact report (EIR) and the substantive provisions require mitigation of harmful environmental impacts. Suggested outlines of the content of an EIS and an EIR are provided. Specific impacts associated with wastewater reclamation projects such as groundwater impacts and growth inducing impacts are discussed. This paper is intended to be a useful tool for the planning of any wastewater reclamation and reuse project. Two examples are given for this purpose.
