This document provides an overview of the course "Environmental Engineering- I" as taught at Mumbai University. It covers 6 main topics: 1) Water Supply and Distribution, 2) Water Quality, 3) Water Treatment Processes, 4) Building Water Supply and Sanitary Fixtures, 5) Rainwater Harvesting, and 6) Air Pollution and Noise Pollution. The water treatment process section describes various steps like aeration, sedimentation, coagulation, flocculation, filtration, softening, and disinfection. The document concludes by outlining the course outcomes which are to understand water supply systems, water quality analysis, water treatment plant design, building water systems, and contributing solutions to environmental issues.
