The proper operation of a water supply system (WSS) requires constant investment. The priority is to provide residents with high quality potable water, in the required quantity and pressure, in accordance with the applicable regulations. The paper presents an assessment of the potential inherent operational risk of a WSS in support of the risk-based investment management process. It is of high importance to invest in the operational safety as it concerns both producers and consumers. The investment engenders additional costs that should partially be supported by the consumers. Thus, the paper presents a methodology to analyse consumers’ readiness to accept water supply services’ additional costs. The proposed methods may underpin a comprehensive program for risk-based investment management and operational decision-making. The case study and the approach in this article concern one particular regional WSS, based on information collected from water consumers. The assessment suggests a willingness to tolerate additional costs in view of enhancing the performance of the water supply services.

Initiated by a case study to assess the effectiveness of the modernisation actions undertaken in a water supply system, some R&D activities were conducted to construct a global predictive model, based on the available operational failure and recovery data. The available operational data, regarding the water supply system, are the pipes’ diameter, failure modes, materials, functional conditions, seasonality, and the number of failures and time-to-recover intervals. The operational data are provided by the water company responsible of the supply system. A predictive global model is proposed based on the output of the operational data statistical assessment. It should assess the expected effectiveness of decisions taken in support of the modernisation and the extension plan.

O Projeto Cisternas nas Escolas objetiva o fornecimento de água para as escolas rurais do Semiárido, utilizando ações estruturais mediante concepção de cisternas como tecnologia social para armazenamento de água pluvial, e ações não estruturais por meio de práticas educativas contextualizadas. Este trabalho objetiva apresentar um pioneiro diagnóstico da infraestrutura dos serviços de abastecimento de água as escolas rurais em que foram implantadas cisternas do Programa Cisternas nas Escolas na Microrregião Serrana dos Quilombos, no estado de Alagoas, especificamente no município de Santana do Mundaú, utilizando-se como metodologia a pesquisa exploratória e qualitativa, com emprego de entrevista semiestruturada e não estruturada, além do uso de questionário, fichas-relatório e registros fotográficos. Das cisternas implantadas nas escolas, apenas uma está sendo parcialmente utilizada. Estão todas elas totalmente desprovidas de acompanhamento técnico, sendo possível perceber a falta de interesse do executivo municipal na promoção da manutenção desses equipamentos. São fundamentais ações que elevem o empoderamento social a essas construções.  Cistern in Schools Program: case study in the mountainous microregion of quilombos in the state of Alagoas, Brazil The reality of many rural schools in the public system presents a still worrying scenario regarding access to water. The Cisterns in Schools Project aims to provide water for rural schools in the Semi-Arid and priority areas located in indigenous villages and quilombola communities, using structural actions through the design of cisterns as social technology for rainwater storage, and non-structural actions through contextualized educational practices. The work aims to present a pioneering diagnosis of the infrastructure of water supply services to rural schools in which cisterns of the Cisterns in Schools Program were implemented in the mountainous dos Quilombos Microregion in the state of Alagoas, specifically in the municipality of Santana do Mandau. The methodology was based on exploratory and qualitative research using semi-structured and unstructured interviews, using a questionnaire, report cards and photographic records. Of the cisterns installed in schools, only one is being partially used. They are all totally devoid of technical monitoring, being possible to perceive the lack of interest of the municipal executive in promoting the maintenance of this equipment.
