This document outlines a presentation for a gravity fed water system project. It includes an introduction to the project components, rationale, objectives to map the area and propose a water supply network. Methodologies included desk studies, literature review, and field work like leveling, traverse, and tacheometry. Outcomes were the spring discharge rate and an L-profile graph of the source to distribution tank elevation. A Gantt chart scheduled the works over 12 weeks. The project concluded by developing surveying skills and providing future benefits to the community's water supply.
