Overview
SIST ISO 24516-1:2026 provides comprehensive guidelines for the management of assets in drinking water distribution networks. Published by the Slovenian Institute for Standardization (SIST), the standard is equivalent to ISO 24516-1:2016. This document targets the strategic, tactical, and operational levels of asset management within water supply and wastewater systems, specifically focusing on the network assets owned or operated by drinking water utilities. Its primary goal is to help organizations maintain the value of existing infrastructure, ensure long-term sustainability, and deliver reliable, high-quality drinking water services.
The standard is broadly applicable to organizations and utilities of all sizes involved in the operation and management of drinking water distribution systems. It emphasizes the importance of systematic and efficient management to safeguard public health, respond to changing requirements, and meet customer expectations for service quality and reliability.
Key Topics
SIST ISO 24516-1:2026 covers a broad range of practical topics and approaches, including:
- Asset Management Principles: Outlines the objectives, requirements, and general principles to guide the asset management process for water networks.
- Strategic, Tactical, and Operational Planning: Provides examples and methods for developing plans at each management level for sustainable infrastructure.
- Data Collection and Analysis: Discusses processes for collecting and analyzing inventory, condition, failure, and performance data to support evidence-based decision-making.
- Asset Condition Assessment: Focuses on assessing the hydraulic, structural, and operational performance of distribution network assets.
- Investigation and Inspection: Details methodologies for conducting investigations and inspections to inform maintenance priorities.
- Maintenance and Rehabilitation: Recommends best practices for maintenance, repair, and rehabilitation planning, including life-cycle cost considerations.
- Performance Monitoring: Advises on setting and monitoring performance indicators aligned with regulatory requirements and customer needs.
- Risk Management: Introduces approaches to assess and manage risks associated with asset failure, including methods for prioritizing critical investments.
Applications
Implementing SIST ISO 24516-1:2026 offers significant advantages for water utilities and organizations managing drinking water distribution networks:
- Lifecycle Asset Value Preservation: The guidelines support maintaining and maximizing the value and longevity of infrastructure assets through proactive asset management.
- Risk-Based Decision-Making: Utilities can systematically identify and address risks, minimizing disruptions and costly emergency repairs.
- Consistent Service Delivery: By following established asset management good practices, organizations ensure high reliability and quality of water supply, meeting both regular and emergency demands.
- Regulatory Compliance: The standard helps ensure adherence to national and international requirements regarding public health, safety, and environmental protection.
- Resource Optimization: It provides a structured approach to prioritize investments, optimize maintenance schedules, and enhance cost-effectiveness.
- Scalable Application: Guidance is applicable to utilities of any size, allowing for tailored implementation based on organizational capacity and complexity.
