Identificação e priorização dos fatores críticos de sucesso na implantação de fábrica digital

A Digital Factory is a concept which improves the collaboration among product development processes. Despite the benefits brought by this concept, failures may occur in its implementation. This paper aims to present the Critical Success Factors in the implementation of a Digital Factory project in a Brazilian company. These factors were identified by an exploratory survey on the implementation of Enterprise Resource Planning and Product Lifecycle Management among other systems. Following this identification, the factors were prioritized using the Delphi Method and the Analytic Hierarchy Process; this evaluation was carried out by professionals from enterprises which implement Digital Factory projects, in Brazil and abroad. Nine factors were identified. The five main priorities were: Continuous Support and Commitment from Top Management; Comprehensive Business Reengineering; Skilled and Experienced Partners; Participation and Commitment of Users; and Appropriate Role of the Project Manager.

Optimization of Large-Scale Hydrothermal System Operation

This paper presents the development of a mathematical model to optimize the management and operation of the Brazilian hydrothermal system. The system consists of a large set of individual hydropower plants and a set of aggregated thermal plants. The energy generated in the system is interconnected by a transmission network so it can be transmitted to centers of consumption throughout the country. The optimization model offered is capable of handling different types of constraints, such as interbasin water transfers, water supply for various purposes, and environmental requirements. Its overall objective is to produce energy to meet the country's demand at a minimum cost. Called HIDROTERM, the model integrates a database with basic hydrological and technical information to run the optimization model, and provides an interface to manage the input and output data. The optimization model uses the General Algebraic Modeling System (GAMS) package and can invoke different linear as well as nonlinear programming solvers. The optimization model was applied to the Brazilian hydrothermal system, one of the largest in the world. The system is divided into four subsystems with 127 active hydropower plants. Preliminary results under different scenarios of inflow, demand, and installed capacity demonstrate the efficiency and utility of the model. From this and other case studies in Brazil, the results indicate that the methodology developed is suitable to different applications, such as planning operation, capacity expansion, and operational rule studies, and trade-off analysis among multiple water users.

Hybrid Water Demand Forecasting Model Associating Artificial Neural Network with Fourier Series

This paper addressed the problem of water-demand forecasting for real-time operation of water supply systems. The present study was conducted to identify the best fit model using hourly consumption data from the water supply system of Araraquara, Sa approximate to o Paulo, Brazil. Artificial neural networks (ANNs) were used in view of their enhanced capability to match or even improve on the regression model forecasts. The ANNs used were the multilayer perceptron with the back-propagation algorithm (MLP-BP), the dynamic neural network (DAN2), and two hybrid ANNs. The hybrid models used the error produced by the Fourier series forecasting as input to the MLP-BP and DAN2, called ANN-H and DAN2-H, respectively. The tested inputs for the neural network were selected literature and correlation analysis. The results from the hybrid models were promising, DAN2 performing better than the tested MLP-BP models. DAN2-H, identified as the best model, produced a mean absolute error (MAE) of 3.3 L/s and 2.8 L/s for training and test set, respectively, for the prediction of the next hour, which represented about 12% of the average consumption. The best forecasting model for the next 24 hours was again DAN2-H, which outperformed other compared models, and produced a MAE of 3.1 L/s and 3.0 L/s for training and test set respectively, which represented about 12% of average consumption.

Meta-models, environment and layers: agent-oriented engineering of complex systems

Traditional software engineering approaches and metaphors fall short when applied to areas of growing relevance such as electronic commerce, enterprise resource planning, and mobile computing: such areas, in fact, generally call for open architectures that may evolve dynamically over time so as to accommodate new components and meet new requirements. This is probably one of the main reasons that the agent metaphor and the agent-oriented paradigm are gaining momentum in these areas. This thesis deals with the engineering of complex software systems in terms of the agent paradigm. This paradigm is based on the notions of agent and systems of interacting agents as fundamental abstractions for designing, developing and managing at runtime typically distributed software systems. However, today the engineer often works with technologies that do not support the abstractions used in the design of the systems. For this reason the research on methodologies becomes the basic point in the scientific activity. Currently most agent-oriented methodologies are supported by small teams of academic researchers, and as a result, most of them are in an early stage and still in the first context of mostly \academic" approaches for agent-oriented systems development. Moreover, such methodologies are not well documented and very often defined and presented only by focusing on specific aspects of the methodology. The role played by meta- models becomes fundamental for comparing and evaluating the methodologies. In fact a meta-model specifies the concepts, rules and relationships used to define methodologies. Although it is possible to describe a methodology without an explicit meta-model, formalising the underpinning ideas of the methodology in question is valuable when checking its consistency or planning extensions or modifications. A good meta-model must address all the different aspects of a methodology, i.e. the process to be followed, the work products to be generated and those responsible for making all this happen. In turn, specifying the work products that must be developed implies dening the basic modelling building blocks from which they are built. As a building block, the agent abstraction alone is not enough to fully model all the aspects related to multi-agent systems in a natural way. In particular, different perspectives exist on the role that environment plays within agent systems: however, it is clear at least that all non-agent elements of a multi-agent system are typically considered to be part of the multi-agent system environment. The key role of environment as a first-class abstraction in the engineering of multi-agent system is today generally acknowledged in the multi-agent system community, so environment should be explicitly accounted for in the engineering of multi-agent system, working as a new design dimension for agent-oriented methodologies. At least two main ingredients shape the environment: environment abstractions - entities of the environment encapsulating some functions -, and topology abstractions - entities of environment that represent the (either logical or physical) spatial structure. In addition, the engineering of non-trivial multi-agent systems requires principles and mechanisms for supporting the management of the system representation complexity. These principles lead to the adoption of a multi-layered description, which could be used by designers to provide different levels of abstraction over multi-agent systems. The research in these fields has lead to the formulation of a new version of the SODA methodology where environment abstractions and layering principles are exploited for en- gineering multi-agent systems.

New water use efficiency strategies to cope with climate change

Crop water requirements are important elements for food production, especially in arid and semiarid regions. These regions are experience increasing population growth and less water for agriculture, which amplifies the need for more efficient irrigation. Improved water use efficiency is needed to produce more food while conserving water as a limited natural resource. Evaporation (E) from bare soil and Transpiration (T) from plants is considered a critical part of the global water cycle and, in recent decades, climate change could lead to increased E and T. Because energy is required to break hydrogen bonds and vaporize water, water and energy balances are closely connected. The soil water balance is also linked with water vapour losses to evapotranspiration (ET) that are dependent mainly on energy balance at the Earth’s surface. This work addresses the role of evapotranspiration for water use efficiency by developing a mathematical model that improves the accuracy of crop evapotranspiration calculation; accounting for the effects of weather conditions, e.g., wind speed and humidity, on crop coefficients, which relates crop evapotranspiration to reference evapotranspiration. The ability to partition ET into Evaporation and Transpiration components will help irrigation managers to find ways to improve water use efficiency by decreasing the ratio of evaporation to transpiration. The developed crop coefficient model will improve both irrigation scheduling and water resources planning in response to future climate change, which can improve world food production and water use efficiency in agriculture.

Robust estimates of climate-induced hydrological change in a temperate mountainous region

A sustainable water resources management depends on sound information about the impacts of climate change. This information is, however, not easily derived because natural runoff variability interferes with the climate change signal. This study presents a procedure that leads to robust estimates of magnitude and Time Of Emergence (TOE) of climate-induced hydrological change that also account for the natural variability contained in the time series. Firstly, natural variability of 189 mesoscale catchments in Switzerland is sampled for 10 ENSEMBLES scenarios for the control (1984–2005) and two scenario periods (near future: 2025–2046, far future: 2074–2095) applying a bootstrap procedure. Then, the sampling distributions of mean monthly runoff are tested for significant differences with the Wilcoxon-Mann–Whitney test and for effect size with Cliff’s delta d. Finally, the TOE of a climate change induced hydrological change is determined when at least eight out of the ten hydrological projections significantly differ from natural variability. The results show that the TOE occurs in the near future period except for high-elevated catchments in late summer. The significant hydrological projections in the near future correspond, however, to only minor runoff changes. In the far future, hydrological change is statistically significant and runoff changes are substantial. Temperature change is the most important factor determining hydrological change in this mountainous region. Therefore, hydrological change depends strongly on a catchment’s mean elevation. Considering that the hydrological changes are predicted to be robust in the near future highlights the importance of accounting for these changes in water resources planning.

Plan de manejo de la costa de Río Negro : observatorio del ecosistema litoral y monitoreo de la biodiversidad

La Provincia de Río Negro, a través de su Constitución y de leyes específicas, adhiere “a los principios que sustentan el desarrollo sustentable de conformidad con la Carta de Naciones Unidas." En la costa marítima de Río Negro existen poblaciones relativamente densas y en aumento básicamente por la inmigración en busca de nuevos horizontes laborales. Los conflictos ambientales que se presentan son comunes a otras zonas costeras: contaminación de las aguas costeras por insuficiente o falta de servicios de tratamiento de aguas residuales, modificación, para desarrollo urbano, industrial y comercial, de hábitats críticos para el sostenimiento de pesquerías, vida silvestre, desarrollo de infraestructura costera inapropiada o mal diseñada que favorece procesos erosivos acelerados y/o interrumpen procesos ecológicos básicos, ocupación espacial desordenada que impide el acceso público a playas y otros terrenos públicos, manejo inapropiado de desechos sólidos, incumplimiento de la legislación en la zona costera; generación de conflictos intersectoriales, desarrollo desordenado de infraestructura con altos costos socioeconómicos, crecimiento de la frontera agropecuaria, deterioro de los suelos (sobrepastoreo, desertificación), introducción de especies exóticas, etc. En Río Negro se han relevado, aunque a diferente escala y muchas veces en forma discontinua, la mayor parte de los ambientes costeros considerados de mayor interés desde el punto de vista ecológico y/o productivo. Ejemplo de productos de estos estudios son las Areas Naturales Protegidas de Punta Bermeja, Caleta de Loros, Bahía de San Antonio, Complejo Islote Lobos y Puerto Lobos, así como la Reserva Pesquera Golfo San Matías. Sin embargo, la información se halla dispersa, por lo que la mayor parte de las veces no se puede contar con un panorama actualizado y globalizador que permita la toma de decisión en forma ágil y un real manejo de las especies y/o de su ambiente. Por ello se considera necesario g enerar un Plan de Manejo de la Costa Marítima de Río Negro, esto es, una clasificación del territorio de acuerdo a su grado de sensibilidad ecológica, expresado en unidades cartográficas ambientales, y estableciendo pautas de manejo para las mismas. Se optó por un Sistema de Inventario y Planificación de Recursos, adaptado a un método de Planificación Participativa en el que se involucra en forma directa, a través de encuentros y talleres, a los diferentes estamentos provinciales, municipales, centros de investigación, organizaciones no gubernamentales ambientalistas, organizaciones intermedias, especialistas. Para la Evaluación de los Elementos e identificación de Zonas de Mayor Sensibilidad Ecológica se utilizó un Método de Evaluación de Riesgos que permite cartografiar grado de Amenazas, Vulnerabilidad y Riesgo.

Images of a groundwater flow system in Nicaragua

Conceptualization of groundwater flow systems is necessary for water resources planning. Geophysical, hydrochemical and isotopic characterization methods were used to investigate the groundwater flow system of a multi-layer fractured sedimentary aquifer along the coastline in Southwestern Nicaragua. A geologic survey was performed along the 46 km2 catchment. Electrical resistivity tomography (ERT) was applied along a 4.4 km transect parallel to the main river channel to identify fractures and determine aquifer geometry. Additionally, three cross sections in the lower catchment and two in hillslopes of the upper part of the catchment were surveyed using ERT. Stable water isotopes, chloride and silica were analyzed for springs, river, wells and piezometers samples during the dry and wet season of 2012. Indication of moisture recycling was found although the identification of the source areas needs further investigation. The upper-middle catchment area is formed by fractured shale/limestone on top of compact sandstone. The lower catchment area is comprised of an alluvial unit of about 15 m thickness overlaying a fractured shale unit. Two major groundwater flow systems were identified: one deep in the shale unit, recharged in the upper-middle catchment area; and one shallow, flowing in the alluvium unit and recharged locally in the lower catchment area. Recharged precipitation displaces older groundwater along the catchment, in a piston flow mechanism. Geophysical methods in combination with hydrochemical and isotopic tracers provide information over different scales and resolutions, which allow an integrated analysis of groundwater flow systems. This approach provides integrated surface and subsurface information where remoteness, accessibility, and costs prohibit installation of groundwater monitoring networks.

Modelling uncertainty of flood quantile estimation at ungauged sites by Bayesian networks

Prediction at ungauged sites is essential for water resources planning and management. Ungauged sites have no observations about the magnitude of floods, but some site and basin characteristics are known. Regression models relate physiographic and climatic basin characteristics to flood quantiles, which can be estimated from observed data at gauged sites. However, these models assume linear relationships between variables Prediction intervals are estimated by the variance of the residuals in the estimated model. Furthermore, the effect of the uncertainties in the explanatory variables on the dependent variable cannot be assessed. This paper presents a methodology to propagate the uncertainties that arise in the process of predicting flood quantiles at ungauged basins by a regression model. In addition, Bayesian networks were explored as a feasible tool for predicting flood quantiles at ungauged sites. Bayesian networks benefit from taking into account uncertainties thanks to their probabilistic nature. They are able to capture non-linear relationships between variables and they give a probability distribution of discharges as result. The methodology was applied to a case study in the Tagus basin in Spain.

Simulación de seguimiento de blancos en sistemas radar. Parte 2

El proyecto consiste en el diseño y estudio de un software cuyas prestaciones estén orientadas a gestionar una simulación de un sistema de radar. El prototipo de este entorno de simulación se ha realizado en el lenguaje Matlab debido a que inicialmente se considera el más adecuado para el tratamiento de las señales que los sistemas de radar manejan para realizar sus cálculos. Se ha escogido como modelo el software desarrollado por la compañía SAP para gestionar los E.R.P.s de grandes empresas. El motivo es que es un software cuyo diseño y funcionalidad es especialmente adecuado para la gestión ordenada de una cantidad grande de datos diversos de forma integrada. Diseñar e implementar el propio entorno es una tarea de enorme complejidad y que requerirá el esfuerzo de una cantidad importante de personas; por lo que este proyecto se ha limitado, a un prototipo básico con una serie de características mínimas; así como a indicar y dejar preparado el camino por el que deberán transcurrir las futuras agregaciones de funcionalidad o mejoras. Funcionalmente, esto es, independientemente de la implementación específica con la que se construya el entorno de simulación, se ha considerado dividir las características y prestaciones ofrecidas por el sistema en bloques. Estos bloques agruparán los componentes relacionados con un aspecto específico de la simulación, por ejemplo, el bloque 1, es el asignado a todo lo relacionado con el blanco a detectar. El usuario del entorno de simulación interactuará con el sistema ejecutando lo que se llaman transacciones, que son agrupaciones lógicas de datos a introducir/consultar en el sistema relacionados y que se pueden ejecutar de forma independiente. Un ejemplo de transacción es la que permite mantener una trayectoria de un blanco junto con sus parámetros, pero también puede ser una transacción la aplicación que permite por ejemplo, gestionar los usuarios con acceso al entorno. Es decir, las transacciones son el componente mínimo a partir del cual el usuario puede interactuar con el sistema. La interfaz gráfica que se le ofrecerá al usuario, está basada en modos, que se pueden considerar “ventanas” independientes entre sí dentro de las cuáles el usuario ejecuta sus transacciones. El usuario podrá trabajar con cuantos modos en paralelo desee y cambiar según desee entre ellos. La programación del software se ha realizado utilizando la metodología de orientación a objetos y se ha intentado maximizar la reutilización del código así como la configurabilidad de su funcionalidad. Una característica importante que se ha incorporado para garantizar la integridad de los datos es un diccionario sintáctico. Para permitir la persistencia de los datos entre sesiones del usuario se ha implementado una base de datos virtual (que se prevé se reemplace por una real), que permite manejar, tablas, campos clave, etc. con el fin de guardar todos los datos del entorno, tanto los de configuración que solo serían responsabilidad de los administradores/desarrolladores como los datos maestros y transaccionales que serían gestionados por los usuarios finales del entorno de simulación. ABSTRACT. This end-of-degree project comprises the design, study and implementation of a software based application able to simulate the various aspects and performance of a radar system. A blueprint for this application has been constructed upon the Matlab programming language. This is due to the fact that initially it was thought to be the one most suitable to the complex signals radar systems usually process; but it has proven to be less than adequate for all the other core processes the simulation environment must provide users with. The software’s design has been based on another existing software which is the one developed by the SAP company for managing enterprises, a software categorized (and considered the paradigm of) as E.R.P. software (E.R.P. stands for Enterprise Resource Planning). This software has been selected as a model because is very well suited (its basic features) for working in an orderly fashion with a pretty good quantity of data of very diverse characteristics, and for doing it in a way which protects the integrity of the data. To design and construct the simulation environment with all its potential features is a pretty hard task and requires a great amount of effort and work to be dedicated to its accomplishment. Due to this, the scope of this end-of-degree project has been focused to design and construct a very basic prototype with minimal features, but which way future developments and upgrades to the systems features should go has also been pointed. In a purely functional approach, i.e. disregarding completely the specific implementation which accomplishes the simulation features, the different parts or aspects of the simulation system have been divided and classified into blocks. The blocks will gather together and comprise the various components related with a specific aspect of the simulation landscape, for example, block number one will be the one dealing with all the features related to the radars system target. The user interaction with the system will be based on the execution of so called transactions, which essentially consist on bunches of information which logically belong together and can thus be managed together. A good example, could be a transaction which permits to maintain a series of specifications for target’s paths; but it could also be something completely unrelated with the radar system itself as for example, the management of the users who can access the system. Transactions will be thus the minimum unit of interaction of users with the system. The graphic interface provided to the user will be mode based, which can be considered something akin to a set of independent windows which are able on their own to sustain the execution of an independent transaction. The user ideally should be able to work with as many modes simultaneously as he wants to, switching his focus between them at will. The approach to the software construction has been based on the object based paradigm. An effort has been made to maximize the code’s reutilization and also in maximizing its customizing, i.e., same sets of code able to perform different tasks based on configuration data. An important feature incorporated to the software has been a data dictionary (a syntactic one) which helps guarantee data integrity. Another important feature that allow to maintain data persistency between user sessions, is a virtual relational data base (which should in future times become a real data base) which allows to store data in tables. The data store in this tables comprises both the system’s configuration data (which administrators and developers will maintain) and also master and transactional data whose maintenance will be the end users task.

Estudio de los criterios de calidad, expectativas y satisfacción de los usuarios de las cartas de servicio de la Administración General del Estado aplicados al sector marítimo. Análisis de las necesidades de desarrollo de futuro

La aproximación de las organizaciones a la mejora de sus procesos ha venido por distintos caminos. Muchas Administraciones Públicas se acercaron a este universo a través del modelo EFQM de calidad y excelencia que surgió en la década de los 80 y que sirvió como referente en el ámbito de la Unión Europea como vía de autoevaluación y determinación de procesos de mejora continua. Está basado en la identificación de los puntos fuertes y débiles aplicados a diferentes ámbitos de la organización, siendo éstos el punto de partida para el proceso de mejora continua. Se trata de un modelo en el que puedes decir que estás en calidad aunque tu puntuación sea muy pequeña, por lo que, por imagen, muchas empresas públicas empezaron a implantarlo. La empresa privada sin embargo se decantó por los sistemas de calidad basados en normas ISO. En estos sistemas has de tener un nivel mínimo para poder exhibir una certificación o acreditación del sistema de calidad. La más extendida es la ISO 9001:2008 ya que es válida para todo tipo de empresa. Este sistema se centra en la satisfacción del cliente y está basada en gran medida en el PDCA, acrónimo de Plan, Do, Check, Act (Planificar, Hacer, Verificar y Actuar). Al tratarse de sistemas documentados, pasados los años se llega a la misma conclusión, aquellas empresas que simplemente tienen un certificado colgado en la pared y que arreglan los papeles antes de la auditoría no tienen nada que aporte valor añadido a la empresa y se autoengañan. La potencia de todo sistema de gestión de calidad reside en aprovechar el potencial de sus recursos humanos dirigiendo los recursos de la empresa de forma eficiente y haciendo participe de los objetivos de la organización a su personal para que se impliquen y sepan que se espera de cada uno. La formación de ingeniero siempre nos hace ser críticos con los modelos existentes y tratar de buscar caminos alternativos que sean más eficientes. Para ello es necesario tener un conocimiento muy preciso de la organización. Por ello, después de más de cinco años trabajando en la Organización, desempeñando diversos cometidos, analizando diferentes esferas de actuación y tras estudiar informes de diferentes organizaciones que supervisan el funcionamiento de la empresa me di cuenta que la Dirección General de la Marina Mercante podía cambiar de forma de actuar para modernizarse y ser más transparente, eficaz y eficiente. Esta tesis versa sobre la posibilidad de implantar un nuevo servicio en la Dirección General de la Marina Mercante que le permita mejorar su competitividad a nivel mundial, como estado de abanderamiento, y que, dentro de nuestras fronteras, haga que sus servicios se reorienten aprovechando el conocimiento de su personal, teniendo en cuenta las necesidades de sus usuarios y los recursos de la Organización. Las cartas de servicio permiten acercar al ciudadano al funcionamiento de la organización. Le informa de las condiciones en las que se presta el servicio, los compromisos de la empresa y la forma en la que puede participar para mejorarlos, entre otros. Por otra parte, la empresa no necesita previamente tener ningún sistema de calidad implantado, aunque, como veremos en el capítulo tres y cuatro siempre ayuda a la hora de tener sistemas de aseguramiento implantados. En el capítulo seis se detallan los objetivos que se lograrían con la implantación de las cartas de servicio en la DGMM y en el capítulo siete se discuten dichos resultados y conclusiones. ABSTRACT Different ways have been used by organizations to approach process improvement. Many Public Administrations chose quality and excellence EFQM model for that approachment. This quality program began in 80 decade and that it was the Europe Unión reference to continuous improvement autoevaluation and determination. It is based on strong and weak points of different organization fields, and they are considered as starting point for continuous improvement. This model allows enterprises to say that they are working on a quality scheme even though their score is very little, and this was why a lot of Public Administrations began using it. Nevertheless private enterprises chose quality management systems based on ISO standards. In these systems there is a threshold you must have to be able to have a certification or an accreditation of quality management system. ISO 9001:2008 is the standard most used because of it can be applied to a great range of enterprises. This system is focused on customer satisfaction and it is based on PDCA, Plan, Do, Check, Act. All these systems are documented ones, so once time goes by the same conclusion is reached: enterprises that have the certificate hung on the wall and that papers are fixed for audits have nothing that give them added value and they self-delusion. Quality management system power is related to the usage of human resources potential to lead enterprise resources efficiently and to make them participate in organization objectives. Naval architect training makes them to be critic with existing models and to try to find alternative ways to be more efficient. To achieve this goal, a precise knowledge of the organization is needed. That is the reason why, after five years in quality related issues in the Organization, in different chores, analyzing our scope and reports of organizations that supervise our operation, I realized that Merchant Marine Directorate could change the way of operation to modernize and be more transparent, efficient and effective. This thesis is about the possibility of implantation of a new service in Merchant Marine Directorate that will make it possible to improve their worldwide competitiveness as Flag State, and that to reorient all services taking into account citizens needs and Organization resources. Citizen’s charters able approachment to organization operation. It gives the following information: which are terms in which service is given, enterprise compromises, ways in which citizen can collaborate to improve them, and etc. Additionally, no quality management system is needed to be implemented. Although we’ll see in chapter three and four that having it is of great help. In chapter six are detailed goals achieved if citizen’s charters are implemented in Merchant Marine Directorate, and in chapter seven conclusions and results are discussed.

Avaliação da quantidade e qualidade dos recursos hídricos superficiais da bacia hidrográfica do rio Sapucaí-Mirim (SP) através do simulador computacional Mike Basin

Fundamental a vida e ao desenvolvimento de qualquer sociedade, a água é um bem precioso e limitado que está se esgotando e sendo motivo de preocupação mundial. O desperdício, a distribuição desigual, o aumento do consumo e a degradação da qualidade da água são motivos que a tornaram escassa e trouxeram à tona a importância do planejamento e gerenciamento dos recursos hídricos. Frente a esta situação, este trabalho buscou avaliar a disponibilidade hídrica quantitativa e qualitativa da bacia hidrográfica do rio Sapucaí-Mirim, SP. Através da aplicação do simulador hidrológico MIKE BASIN, foi analisado o desempenho do sistema de recursos hídricos, o conflito existente entre os usos múltiplos e a concentração dos parâmetros OD e DBO nas águas do rio que recebe efluentes domésticos, muitos deles sem nenhum tratamento. Apesar da quantidade de água ser suficiente para atender às demandas, o estudo mostra que a geração de energia elétrica está comprometida e a água está se esgotando qualitativamente, evidenciando a necessidade e urgência de se implantar estações de tratamento de esgoto.
