Avaliação da perda de arrecadação pela não prestação do serviço de abastecimento público de água em edifícios residenciais

The service provider asks for billing when the residential building uses its own water supply system. Thus, the objective of the work is to quantify the revenue losses (R$) that the Pará Sanitation Company (COSANPA) suffers for not supplying the 24 residential buildings located in the area in the third sector, located in the municipality of Belém in the State of Pará. A document consultation was carried out on the volumes of water consumed and billed in 25 residential buildings with water supply from the Pará Sanitation Company (COSANPA) to then estimate the values (volume and possible billing in reais) in residential buildings that use own source of water supply in the area of Cosanpa’s third water supply sector. The data collection source was entirely from the integrated sanitation service management system (Gsan). The Research was developed in three stages. The first stage consisted of identifying the residential buildings that use Cosanpa’s water and identifying the residential buildings that do not use Cosanpa’s water. The second stage consisted of collecting and systematizing water consumption information for the two groups of selected buildings (buildings supplied by COSANPA and buildings supplied with their own system). The third and last consisted of the comparative analysis of noncollection (monetary R$) in residential buildings not supplied with water by COSANPA, based on the premise of collection of residential buildings served by the Pará Sanitation Company (COSANPA). It was verified that the company failed to collect BRL 3,142,281.65 (three million, one hundred and forty-two thousand, two hundred and eighty-one reais and sixty-five cents) in five years, which represents 45.97% of the amount collected by the buildings supplied by the company

Determinação de custo de referência para elaboração de projetos e obras de rede coletora de esgoto sanitário
(Universidade Federal do Pará, 2023-01-26) COSTA, Magaly Santos Pinheiro; PEREIRA, José Almir Rodrigues; http://lattes.cnpq.br/9918600634569244
With the unavailability of financial resources and the high cost of implementing conventional sanitary sewage systems of the absolute separator type, regions with disorderly occupation and, often, subject to unfavorable topographical situations, end up not being contemplated with basic sanitary sewage services. Complementarily, this issue is accentuated by the lack of local references regarding the costs of implementing sanitary sewage collection networks in Pará, as well as parameters for the conception and elaboration of projects in the state context. In this sense, it is necessary that the typology of the sewage network to be implemented in each location be carefully planned, bearing in mind the particularities of each area, as well as the technical criteria to be adopted in the project. Considering the problem addressed, the objective of the present research was to establish values, expressed in R$/m of COSANPA's sanitary sewage collection network project, for analysis and identification of the budget worksheet items referring to the collection network and household connections, being updated the costs in the spreadsheet for the base date October 2022. In the first stage, the projects and works of the sewage collection network were surveyed in the COSANPA and SEDOP database, from this survey, the projects were selected for the preparation of the Technical Sheet, containing the main information on the sanitary sewage system. In the second stage, from the budgets of each project, the construction values practiced in projects and works of sanitary sewage collection network under the management of COSANPA and SEDOP were identified, then the budgets were analyzed and the values for the same were updated. base date (October 2022), using the National Civil Construction Index – INCC of the Getúlio Vargas Foundation – FGV. In the third stage, the values of the sewage collection network of each project were compared. In the fourth stage, a range of values for the construction of a sewage collection network was presented, expressed in R$/meter of network. This range of costs will make it possible to determine a regional reference indicator regarding the implementation cost per meter of the sanitary sewage collection network, allowing its application in studies, reports and regional projects for the collection network; contributing with Specialized Consultancies, with Higher Education Institutions and with the Public Power, with actions that culminate in the increase of sewage coverage in the Metropolitan Region of Belém.
