The cost of building and maintaining a reservoir can vary significantly based on factors like size, location, purpose, and environmental considerations. Initial construction costs can be substantial, encompassing expenses for land acquisition, engineering, infrastructure like dams and outlet structures, and environmental assessments. Ongoing maintenance costs include monitoring water quality, safety inspections, and addressing infrastructure wear and tear.
Environmental mitigation and rehabilitation efforts can also contribute to the overall expense. The cost of reservoir maintenance is influenced by its intended purpose, its surrounding environment, and the need for upgrades or repairs over time. As such, costs can range from millions to billions of dollars for large-scale reservoir projects.
