Contracting of works for the construction of a new well for the supply of drinking water in the center of Alàs

The drilling is planned to be done with a rotopercussion system at a depth of 120 meters: - first 10 meters drilling with a diameter of 312mm and steel tubing with a diameter of 260mm and a thickness of 6mm. - The next 110 meters of drilling with a diameter of 250mm with a steel tube with a diameter of 210mm and a thickness of 5mm (the last 18 meters will be with a slotted tube for filtering the water). A 15 m gravity ring foundation will be made. It is also planned to clean the well with compressed air. The next step will be the capacity of the well for 24 hours, for this a team will be used with the capacity to push 10 m3/ha 120 m, with control of flows and levels. It is also planned to control the recovery of the well and execute the corresponding final report. Once the well has been measured and having verified that the flow obtained is sufficient for the flow demand, a complete analysis of the extracted water will be carried out, according to the specifications of RD 3/2023, of January 10, which establishes the technical and sanitary criteria for the quality of drinking water, its control and supply. In the upper part of the well, a box with internal dimensions of 1m x 2m will be placed, raised 1m from the ground, which will also house the electrical panel of the pump and the remote control box. This casket will be placed on a reinforced concrete slab of 3m x 2m and 0.25m thick. A well protection perimeter of 8.4 x 7.4 m is planned.
