Executive Director's Message

Japan Water Works Association (JWWA), a Public Interest
Incorporated Association, was established on May 12th, 1932
with the aim of spreading water supply in Japan and sounddevelopment of water supply technologies.
Water supply is an essential lifeline for people’s daily life as well
as social and economic activities.
Therefore, it is particularly important to provide safe and stablesupply service as well as quality water.
JWWA’s main activities include research and study of watersupply management, technologies and water quality.
JWWA also provides various service such as inspection andcertification of water supply related products to maintain stable
and safety water supply, which is indispensable for people’s
daily life.
In addition, JWWA actively lobbies and makes recommendations
to government for solving water utilities' related issues in Japan,
so as to help sastain water services toward the future.

1Background and Organization

At the time when the Federation of Water Authorities(JWWA’s predecessor) was established in 1904, Japanwas in an early stage of introducing modern water supply.
Modern water supply service was provided only in major
port cities including Yokohama (service started in 1887),
Hakodate, Nagasaki, Osaka, Tokyo, Hiroshima and Kobe.
In those days, there were growing tendency among water
utilities toward research and study of subjects related toconstruction, public hygiene and administration of watersupply, and water quality was the most critical issue.
Dr. Tinkichi Toyama (Director of Tokyo Institute of
Public Health), who advocated establishing a “standard
method of water quality examination”, called on holdinga “Consultative Meeting for Establishing a Standard
Method of Water Quality Examination” (the first meeting
was held in Tokyo), and this became the origin of JWWA.
In the second meeting held in the following year andsubsequent meeting, not only water quality but generalissues relating to water supply such as purification anddistribution engineering.
This led to the current tradition in the water-supply
utilities that all stakeholders are involved to collectively
find solutions for various issues.
As water supply started to cover cities and towns in Japanand the number of cities participating in the meeting
increased, the role of the “Federation of Water Authorities”
became important.
JWWA established on May 12th, 1932 on behalf of theFederation under the approval of the Minister of Interior.
(The body was changed to Incorporated Association in1956 and became Public Interest Incorporated Associationin 2013.)
Currently, there are seven regional branches, 46
prefectural branches as well as five branches in Hokkaido.
The secretariat consists of five departments, one regional
office, one institute and one center. JWWA is committed
to fulfilling our members’ objectives for advancing watersupply service and providing safe and sustainable watersupply for the people.

utilities, conducts research and studyof inspection service from expert
viewpoints. The committee aims toprovide optimum inspection services
by improving inspection techniqueand methods. The Inspection
Outline Task Force establishedunder the Examination Committee
discusses compliance with the“Ministry ordinance on technicalstandards of water supply facilities”
and appropriateness of inspection
methods. Five inspection offices and16 local suboffices provide efficient
inspection service.
In order to provide a safe andstable water supply for the public,
it is essential to use quality andreliable water supply equipment
and materials. Thus, third-party
performance testing of water supply
equipment and materials is becoming
more important.

Four Inspection Service

1. Performance Testing and Inspection

Products are tested at inspection
facilities based on technicalstandards and purchasers’ criteria tomaintain quality. Test items include
performance testing such as hygiene
levels and overall inspection.
2. Inspection Certification MarkThe inspection certification mark is
attached to products that are verified
for their proper performance throughproduct inspection process. The
certification mark enables purchasers
such as water supply utilities to easily
identify quality products. (See lower
right)
3. Inspection Certificates
To clearly assure that a product has
passed inspection in writing, JWWA
issues a quality conformity certificate
to the manufacturer. The manufacture
issues an inspection certificate for the
product with the quality conformity
certificate on request from watersupply utilities to prove the productquality. (See the figure below)

JWWA inspection service

4. Listing
Manufactures’ inspection facilities
and certified water supply equipments
and materials are registered with
JWWA and listed on our website.
JWWA aims to improve products
quality and to enable purchasers suchas water supply utilities to choose
quality water supply equipment andmaterials.

JIS Mark Certification Service

Quality Certification Service

Since April 1997, JWWA has been
providing third-party certification
service that verify and certify watersupply equipments with the “Ministryordinance on standards of watersupply equipment structures andmaterials (the Ministry of Health andWelfare Ordinance No. 14, March 19,1997)” specified under the Waterworks
Law.
In addition, since October 2000,
the third-party certification service
have been extended to water supply
equipments and materials and water
treatment chemicals, which are
specified in the “Ministry ordinanceon technical standards of water supply
facilities (the Ministry of Health andWelfare Ordinance No. 15, February
23, 2000)” under the Waterworks Law.
Products verified and certified by
JWWA are listed on JWWA’s website.

Third-party certification process

JWWA’s third-party certificationconsists of two process: “certification
registration” and “quality verification”.
JWWA, upon request from amanufacture or a dealer, inspects
water supply products such as service
pipes, equipments, materials andwater treatment chemicals withstandards specified by the Waterworks
Law. And conformed products areregistered on the book or website.
JWWA conducts “qualify verification”
before a certification-registeredproduct goes into the market. In
quality verification process, JWWA
checks manufacturing process of the
product. Once the product passes

quality verification, the productis registered as a JWWA certified
product.
There are two types of quality
verification process; Self-inspectionJWWA check and assess amanufacture’s quality control system.
If the system is appropriate, JWWA
approves his self-inspection as
JWWA’s quality inspection; Samplinginspection - JWWA it self sample
product for inspection.

Target Products

The following target products:① Service installation: service pipes
and fittings directly connected to the
distribution pipes (service pipes, taps,
valves, joints, water meters)② Materials: used for water
purification process (e.g. Surface
coating materials, filtering materials)③ Water treatment chemicals: (e.g.
Flocculants, powdered activatedcarbon, disinfectant)Examination Criteria

The following criteria are applied toquality verification:① Basic criteria (service pipes/watersupply equipments)
Performance standards specified by
the Ministry ordinance on standardsof water supply equipment structuresand materials② Technical criteria (water supply
materials/chemicals)
Technical standards according to
the Provision 4, Article 5 of theWaterworks Law③ Special criteria (service pipes/watersupply equipments)

In addition to the basic criteria, otherperformance standards (JWWA’ own
standards or other organizations’standards acknowledged by JWWA)

Quality Certification MarkA “quality certification mark” isattached to certified products asquality confirmation. This certification
mark enables consumers to easily
check products’ quality with standards
specified by the Waterworks Law.
Quality certification marks canbe attached by pasting stickers,
engraving, molding or printing.
Typical quality certification marks
are as follows:

GLP Accreditation Service
Water Supply GLP

Since tap water is used as drinking
water by consumers, quality testingof tap water especially requires ahigh level of reliability. To maintainreliability of water quality testing,
JWWA defined the “Guidelines for
Tap Water Quality Testing Good
Laboratory Practice” (“GLP for Water
Supply” in short) in September 2004.
This GLP for Water Supply covers
legal requirements and accreditation
standards for certified water quality
testing authorities specified by the
Ministry of Health, Labour andWelfare. In addition, while this GLP
for Water Supply conforms to ISO
9001, actual conditions of water

quality testing organizations are
considered for practical application.
In terms of water quality testing
requirements, part of ISO/IEC 17025
provisions are selected for the samepracticality.
To enable water quality testingorganizations to implement a quality
assurance system in line with the
GLP for Water Supply, JWWA has
been providing GLP accreditation
services since August 2005.

Requirements

To succeed “GLP for Water Supply”
accreditation, a water quality
testing organization needs tomeet administrative and technicalrequirements of water quality testing
specified in the GLP for Water Supply
and takes inspection by JWWA.
Administrative requirements include
establishment of a quality control
system, clarification of management
responsibilities, proper record
management and scheduled training
programs. Technical requirements
include standard work procedures
based on the applicable laws specified
by the Ministry of Health, Labour andWelfare, proper inspection facilities
suitable for water quality testing andproper management of inspection
equipment.
Accreditation objectively certifies
that an accredited water quality
testing organization performs proper
inspections under a controlled
structure and actively implements
measures for maintaining reliabilityof quality testing results.

Accreditation Status

JWWA has the “GLP for Water
Supply Service Committee” and the“GLP for Water Supply Accreditation
Committee” for maintaining
fair and independent inspection
and accreditation services. Eachinspection for accreditation by
JWWA is conducted objectively. Since
the first accreditation granted in
December 2005, 117 water quality
testing organizations including watersupply utilities and water quality
testing authorities registered underthe Article 20 of Waterworks Law
have been certified as GLP for Water
Supply accredited organizations by
the end of March 2015.
