Diagnosis of the public water supply in the city of Maringa, PR and its relation to the concept of smart cities

With the development of cities in a more integrated and innovative management for urban sectors, the smart cities emerge, usually incorporating this evolution using the Information and Communication Technology (ICT), necessitating investments in technology and innovation in the public policies. In light of this context, the purpose of this paper was to carry out the diagnosis of the city of Maringa concerning innovation and the use of ICT in the potable water public supply sector. It was conducted interviews with the responsible for the concessionaire of the water supply in Maringa (SANEPAR), and also document evaluations. The results attest to the development of a project elaborated by SANEPAR in partnership with Parana Meteorologic System (SIMEPAR), with the intention of a more intelligent water supply system, that allows the prediction of possible floods in the water catchment plant by heavy rainfall. Thus, it can be concluded that there is the intention of implementing smart technologies, beginning with the protection to the catchment of the water, that can be extended to the operation of the whole water supply system of the municipality of Maringa

Modelagem computacional da rede de drenagem urbana usando alternativas LID em uma sub-bacia na cidade de Maringá, Paraná, Brasil

With urbanization development, inundations and urban floods become more frequent. In the city of Maringa, Parana, this type of event is often observed in some specific dense urban locations, resulted by intense rainfall. In this context, the objective of this paper is to perform a computational modelling in the urban drainage network, most specifically in the sub-basin defined by the intersection of avenues Guaiapo and Palmares, in the city of Maringa, Parana, considering the current situation and with the application of Low Impact Development (LID) compensatory techniques. In this regard, the computational program SewerGEMS® was used to develop the scenarios simulations. The results shown that the actual network is undersized (Scenario 01), and it is proposed the adoption of LID compensatory measures (Scenarios 02, 03 and 04). The computational modelling in the elaboration of the scenarios was effective and it may support the municipal urban management with the implementation of an adequate and efficient system of stormwater management.Com o avanço da urbanização, tornam-se frequentes os problemas de alagamentos, inundações e enchentes urbanas. Na cidade de Maringá, Paraná, constatam-se alagamentos frequentes, decorrentes de chuvas intensas, em pontos específicos densamente urbanizadas. Neste contexto, o objetivo desse trabalho é elaborar cenários de um trecho da rede de drenagem urbana, mais especificamente no ponto de cruzamento entre as avenidas Guaiapó e dos Palmares, localizado na cidade de Maringá, Paraná: com a situação atual e utilizando técnicas compensatórias de Low Impact Development (LID). Para isso, foi utilizado o programa computacional SewerGEMS® a fim de realizar as simulações dos cenários propostos. Os resultados mostraram que a rede atual no trecho considerado está subdimensionada (Cenário 1) e uma das soluções propostas é a adoção de técnicas compensatórias LID para construção dos Cenários 2, 3 e 4. Conclui-se que a modelagem computacional para a elaboração de cenários mostrou-se efetiva e pode ser uma grande aliada para fornecer subsídios para a gestão municipal urbana, auxiliando na implementação de um manejo de águas urbanas adequado e eficiente.
