The purpose of this document is to provide improvement proposals to avoid seepage in the Coltani - Tacna dam by analyzing the technical record of the project, which is currently paralyzed. These will be carried out through the implementation of an impermeable wall made up of Secant Piles, which is a technique used in earth dams to face this kind of civil engineering problems. The research will be divided into strategic sections for global understanding, maintaining an order of information. First, general concepts such as the types of earth dams, their main elements, technical requirements, main faults, soil improvement techniques, seepage, among others, will be defined. Subsequently, the general and specific characteristics, both geological and geotechnical, of the project land will be detailed, compiling the necessary information from the soil study. Then, a seepage analysis will be carried out, using the SLIDE program, analyzing the behavior of the water flow and response flows of the dam in its initial condition, that is, without the implementation of the screen wall. Once this behavior has been analyzed, the Maximum Permissible Seepage Flow will be obtained, whose value will serve as the basis for the different proposals to be considered. The variations of the alternatives for seepage control will be based on two different diameters (1.3 and 1.5m) of Secant Piles with 3 different possible locations, according to the dam (start, center and end), with depths between 10 - 59m. Afterwards, the construction process of the technique will be analyzed, the comparison in economic terms by the execution cost and the plans and diagrams of the respective proposals to be considered will be presented. Finally, the alternative that presents the greatest potential based on constructability and cost will be chosen to be implemented as a solution for water seepage in the Coltani dam.
