Water scarcity has become a major problem for sustainable development. Water scarcity is not only affected by hydroclimatic conditions that result in the amount of freshwater availability, but also by industrial demand for water, as well as socioeconomic factors and government policies. With the global drive towards the transition of renewable energies, such as solar, over those that use fossil fuels, it is necessary to study how, when and how much of the water resource these new forms of energy generation use and how they reuse it, especially in areas with deficits hydric. For this reason, the concern is generated to review the photovoltaic projects in Chile and their commitments acquired in relation to the consumption and reuse of water, the fulfillment of these commitments and/or the degree of supervision of the environmental authority (SMA) with the objective of certifying the adequate treatment, management and disposal of the wastewater generated in the construction stage of solar plants in the north and center of the country, as they are areas with significant water scarcity. In addition, on the one hand, to review current Chilean regulations and analyze their effectiveness and relevance to the topics covered in this paper; and on the other, to study the technologies used around wastewater treatment plants, their advantages, and disadvantages, and how to manage the reuse of wastewater in various areas that could be of great contribution. To carry out the study, the EIA/DIA of 25 photovoltaic projects were reviewed, with significant energy production (<100 [MW]), located in communes in the north and center of Chile, through the SEA virtual platform. This study was carried out through a database with parameters such as daily, monthly, and total water consumption [m3], construction period, energy produced, among others; reported by the projects. The IFA of the SMA was reviewed through the SNIFA platform of the projects under study. The study made it possible to establish that there are no inspections by the authority or information that allows knowing the level of compliance of the projects in terms of the management of wastewater generated during their construction stage, which would reflect a null interest of the Chilean institutionality for the destination of the water resources of the projects, a critical situation given the evident water scarcity that the country and the world are experiencing in these times. On the other hand, analyzing the regulations and the bibliographic review of scientific articles, it was concluded that the existence of state-of-the-art technology to treat wastewater, as well as regulations that do not restrict reuse, are factors that would contribute to a conscious and responsible implementation of the resource and would contribute to reducing the water deficit in areas that urgently require water policies in the short and medium term....

An environmental management system (EMS) is a tool that allows a company to determine, control, and prevent the environmental impacts generated by its operation, complying with both legal requirements and the needs of top management and stakeholders. The case study for this project corresponds to the company "plastic and metal recovery plant", which currently has a sanitary resolution authorizing the handling of non-hazardous waste, allowing the recycling of plastic and metal packaging that do not present hazardous characteristics through reconditioning or crushing for revaluation. However, there is a need to expand the activity for the handling of hazardous waste, which will generate wastewater that must undergo prior treatment before being discharged into the sewer. The general objective of the degree seminar was to develop an Environmental Management System (EMS) for a "plastic recovery plant" company. To achieve this objective, specific objectives were identified, which included compliance with current Chilean regulations, taking into account the chemical nature of the packaging and the company's activity, as well as conducting a diagnosis through a matrix of legal requirements, and a survey and analysis of the characteristics of the packaging. With this information, procedures for storage, handling, and revaluation of the packaging were proposed, and a proposal was generated for the implementation of a packaging washing plant that would allow the treatment of wastewater. The work carried out made it possible to determine that the EMS of the "plastic recovery plant" company must implement at least 134 legal requirements corresponding to the 8 regulations reviewed, ranging from labor regulations to the processing of sanitary authorizations for its operation....
