Abstract

Most of the urban water infrastructure around the world was built several decades ago and nowadays they are deteriorated. As such, the assets that constitute these infrastructures need to be updated or replaced. Since most of the assets are buried, water utilities face the challenge of deciding where, when, and how to update or replace those assets. Condition assessment is a vital component of any planned update and replacement activities and is mostly based on the data collected from the managed networks. This collected data needs to be organized and managed 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 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' experiences.

Keywords: condition assessment, data, information systems, management, urban water infrastructure

Introduction

Urban water infrastructures are constituted by a large variety of physical assets (e.g., tanks, pumps, pipes). These assets deteriorate due to their natural aging and non-controlled processes (e.g., pipe's poor production quality, external actions such as excavation) and, as a result, need to be updated or replaced (i.e., "rehabilitated) to improve the assets' condition to its “as-new” condition if practicable.[1][2] By extension, it is vital to then assess the physical condition and functionality of urban water infrastructures in order to estimate the remaining service life and asset value.[3] Since urban water infrastructure assets are mostly buried, the assessment of their condition must be based on reliable pre-acquired information.

Over the past few decades, water utilities have made significant investments in implementing different information systems to address the increasing complexity of the daily control, operation, management, and planning of their systems.[4] Data is usually collected, stored, managed, and analyzed using various information systems, which are often dispersed across different divisions of a water utility. In particular, the activity of condition assessment is data intensive and uses a plethora of information systems.[5]

This paper highlights the importance of data and information systems management for urban water infrastructure condition assessment based on the authors' experiences obtained from some Portuguese R&D projects. These projects aimed to develop a platform to assist small- and medium-sized water utilities with their low digitalization maturity level to better integrate data from their different existing information systems to assess the condition of their water distribution systems.

Urban water infrastructure condition assessment

"Condition assessment" may be defined as the identification of the likelihood that an asset will continue to perform its required function[6] and is an essential part of any urban water infrastructure asset management (IAM) processes and methodologies.[2][7][8][9][10][11][12][13][14] Further, ISO 55000 defines "asset management" as a coordinated activity carried by an organization to realize value from its assets involving a balancing of costs, risks, opportunities, and performance benefits.[15] As such, we can say that condition assessment may involve risk, performance, and cost methodologies.

The most common risk management frameworks used are in accordance with the reference standards AS/NZS 4360:2004[16] and ISO 31000:2018.[17] The frameworks address topics such as:

  • risk assessment, the processes of risk identification, risk analysis, and risk evaluation[18];
  • performance assessment system, a set of data, calculations, performance metrics, and contextual information that allow the evaluation and reporting of the performance of a single asset, a whole infrastructure, a provided service, or a utility[19][7]; and
  • cost assessment, which evaluates the deterioration of an infrastructure and the quantification of the investment needed for its rehabilitation, as well as the total cost for comparison of different alternatives of rehabilitation actions.

In 2020 research published by Carriço et al.[20], five Portuguese water utilities defined a set of 16 performance indicators (Table 1) aimed towards the assessment and prioritization of water supply systems (WSS) or district metering areas (DMA) for rehabilitation. These performance indicators were regarded as having the utmost importance and were implemented in a platform allowing its calculation after the integration of the required data.[20]
