2. Description of the ISO 24512:2007 Standard
Formal Title: “ISO 24512:2007 Activities relating to drinking
water and wastewater services – Guidelines for the management
of drinking water utilities and for the assessment of drinking
water services”
In 2007, to promote increased consumer confidence in the water management
sector, the International Standards Organisation, issued its first ever standard on the
best practise in the management of drinking water utilities.
The document forms part of a suite of standards created in 2007, the others are;
ISO 24510: 2007 Activities relating to drinking water and wastewater services –
Guidelines for the assessment and for the improvement of the service to users
ISO 24511: 2007 Activities relating to drinking water and wastewater services –
Guidelines for the management of wastewater utilities and for the assessment of
wastewater
services.

ISO 24512:2007 is based upon a “plan-do-check-act” model. An essential element
of this approach is the establishment of core objectives that embrace;
A. Protection of public health
B. Meeting users needs and expectations
C. Service Provisions under normal and emergency conditions
D. Sustainability of the water utility
E. Promotion of sustainable community development
F. Protection of the environment
Compliance with these objectives is achieved through establishing clear
management and operational procedures and mechanisms for the review of
performance (i.e. metrics).

What Prompted Limerick County Council to initiate this Project.
1. There was a strong established management system in place.
2. In Limerick County Councils Corporate Plan 2009-2014 , objective number
one under the Water Services heading is “To ensure that the people of County
Limerick have access to potable water, and to benchmark public water supplies
against international standards”.
3. Limerick County Council recognised that the root cause of most water quality
and water supply incidents worldwide is management system failures which can
be controlled through improved design, system controls and operational systems
management.

The main improvements undertaken to comply with the standard were;
A. Establishment of Objectives and Metrics for Assessment of Compliance
B. All hazards with regard to;
• Food Safety
• Quality
• Environmental
• Occupational Health And Safety
were identified, they were then Risk Assessed and Control Measures were developed
(including Critical Control Points)
C. Standard Operating Procedures and Work instructions were developed for all processes
D. Administration Procedures were developed for maintenance, servicing, calibration, records,
meetings and other items.

Physical improvements to the Plant to attain the
Standard
The Plant was physically improved by;
A. Implementing the Control Measures as identified in the
Risk Assessment Process
B. Implementing the 5S Standard
What is 5S?
5S is a system of work organisation originally developed
in Japan based around housekeeping principles.
A close translation of the five stages in the housekeeping
approach is;
1. Sort
2. Set in order
3. Shine
4. Standardise
5. Sustain

4. Benefits in Achieving this Standard
1. Sense of Security for the Public
2. The Standard Formalises Good Management Practises
3. Water Safety Plans
4. Continual Improvement & Investment into the Plant
5. Inward Investment to the Area

Adoption of new CEN Standard for Drinking Water
EN 15975:2013 – Security of Drinking Water Supply, Guidelines for Risk
and Crisis Management
The European Commission (EC) requested the
European Committee for Standardization (CEN) to
develop standards in the area of “Security and the
Citizen” for drinking water supplies
Out of this, the following documents were developed;
• EN 15975-1 deals with Crisis Response
Follows the Drinking Water Incident Response
Plan approach (DWIRP)
• EN 15975-2 deals with Risk Management
• Follows the Water Safety Plan approach
• EN 15975-2 has been submitted to CEN
members for formal vote
• NSAI has indicated that it will vote “yes” to
acceptance as a European Standard

Risk Assessment Process for EN 15975-2
EN 15975-2 : Risk Crisis and Management describes a set of risk assessment
procedures to try to ensure a stable and secure drinking water supply
Covers from source to point of use
Process involves;
• Identify hazards
• Assess the risk
• Select control measures
• Verify the risk management approach
• Improve the integrity of the supply system
If control measures fail or are overwhelmed, processes developed for crisis
management (Part 1) would be employed
Section 4 of the EN 15975-2 standard outlines its Risk Assessment Methodology
• Consistent and systematic to allow for analysis and comparison of risks
• Interdisciplinary team & external experts if necessary
• Decision support tool for the Water Suppliers business planning process

Stakeholders involved
• Multi-barrier principle
• All players to cooperate
• Achieve targets of safe
and secure water

Benefits of Standard EN 15975-2
• Risk Assessment is focused on all phases of entire water supply chain (from
source to tap)
• The Standard is a risk management strategy in all aspects of the WSA’s
operations
• Contributes to meeting water suppliers legal requirement to “ensure” water is
safe and secure
• Supports the holistic approach of the WHO Water Safety Plans
• Supports the EPAs WSP Advice Note No. 8
EPA developing a WSP web-based tool which will mirror the requirements of the
Standard
