Overview
ISO/TR 24589-1:2024 - Examples of good practice for the management of assets of water supply and wastewater systems - Part 1: Water supply - is a Technical Report (first edition) that provides selected, practical examples to support implementation of the ISO 24516 asset management guidelines for drinking water supply systems. Intended as a companion to ISO 24516-1 and ISO 24516-2, this document focuses on operational and technical good practices that help utilities realize value from existing assets across strategic, tactical and operational plans. Annex A provides a recapitulative summary of the examples covered.
Key Topics
The report organizes practical examples and tools under clear technical themes:
- Principal aspects - objectives, strategies and process structure tailored to waterworks, distribution networks and multi-site utilities (Clauses 4.1–4.3).
- Investigation methods - non‑destructive pipe condition assessment, HDPE considerations, hydraulic performance checks, and storage tank visual inspection techniques (Clause 5).
- Assessment tools - degradation and service‑life modelling, maturity assessment of operations, criticality analyses for networks and treatment plants (FMECA examples), and multicriteria likelihood-of-failure evaluations (Clause 6).
- Implementation - prioritization approaches, sustainable field works and CAPEX optimisation tools for renewals (Clauses 7 and 9).
- Operation & Maintenance (O&M) - planned leakage prevention, flushing, on‑call service structures, energy monitoring/optimisation, monitoring and control, and civil structure maintenance (Clause 8).
Practical applications
ISO/TR 24589-1:2024 is practical and actionable for:
- Water utilities seeking to improve asset management of pipes, storage tanks and treatment assets.
- Asset managers and engineers implementing condition‑based maintenance, criticality ranking and rehabilitation planning.
- Consultants and solution vendors developing inspection, hydraulic modelling and prioritization tools.
- Regulators and planners wanting consistent examples of sustainable renewal, leakage management and energy optimisation.
Practical outputs include improved prioritization of renewals, reduced lifecycle costs, better risk‑based decision making, and demonstrable alignment with ISO 24516 asset management guidelines.
