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
