The increasing demand for water from various sectors such as industry, domestic, agriculture has led to an increase in the need for investment to develop water resources infrastructure, particularly dams. The dam is one of the infrastructures that have a long service life. It requires proper management to maximize its use which is also comparable to the costs incurred. The Life Cycle Cost (LCC) method is one method that can be used to estimate the cost during the operation of the dam. It considers the financial costs at different life cycle stages, including capital costs, costs of operational, maintenance costs, replacement and rehabilitation costs, demolition, and residual costs. Life Cycle Costing is an inseparable part of decisions about financially expensive investments. LCC works by calculating the life cycle length, future costs, discount rate, and inflation. This study aims to define the integration of the life cycle costs and the management of dam assets. The author used a literature review method from 28 compatible literature. By applying LCC to the dam, the cost of each stage of the dam’s service life can be determined to obtain economic financing.
