On December 28, 2019, the seismic sequence to the South-Southwest of Puerto Rico began with a magnitude 4.7 Mw tremor, and what is considered the main event of this sequence occurred on January 7, 2020, a magnitude 6.4 Mw tremor, with epicenter 12.7 km south of Guayanilla. This strong tremor with a depth of 7 km, had a maximum intensity of VIII in Guánica and caused considerable damage throughout Puerto Rico. Since then, this area has remained active, registering over 16,000 tremors until August 2021. Among the damages caused by said telluric movements is a landslide due to a fault in the slope where the Monte Pelao Tank is, in the community of Alturas de Belgica in Guánica. This project has the objective of establishing a cost estimate for the demolition works of the existing tank and the construction of a new tank and pumping station for the supply of drinking water to the families of the mentioned sector. Key terms—construction estimate, water tank, earthquake, takeoff.
