Abstract
Most of urban water infrastructure around the world were built several decades ago and nowadays they are deteriorated. So, the assets that constitute these infrastructures need to be rehabilitated. Since most of the assets are buried, water utilities face the challenge of deciding how, where and when to rehabilitate. Condition assessment is a vital component on plan rehabilitation actions and is mostly based on the data collected from the managed networks. This collected data need to be put together in order to be transformed into useful information. Nonetheless, the large amount of assets and data involved makes data and information management a challenging task for water utilities, especially in those with as lower digital maturity level. This paper highlights the importance of data and information systems' management for urban water infrastructure condition assessment based on the authors' experience.
Highlights
Urban water infrastructures are constituted by a large variety of physical assets
Condition assessment may be defined as the identification of the likelihood that an asset will continue to perform its required function (AWWA, 2019) and is an essential part of any urban water infrastructure asset management (IAM) process
In a Portuguese R&D project, five water utilities have defined a set of 16 performance indicators (Table 1) aiming the assessment and prioritization of water supply systems (WSS) or district metering areas (DMA) for rehabilitation
Summary
Urban water infrastructures are constituted by a large variety of physical assets (e.g., tanks, pumps, pipes). This paper highlights the importance of data and information systems’ management for the urban water infrastructure condition assessment based on the authors’ experience obtained from some Portuguese R&D projects. These projects aimed to develop a platform to assist small and medium sized water utilities with low digitalization maturity level to integrate data from their different existing information systems to assess the condition of their water distribution systems
