EPA Specification for WaterSense Labeling of Certification Programs for
AA/3tCTScnSC Irrigation System Installation and Maintenance Professionals
Specification for WaterSense Labeling of Certification Programs for
Irrigation System Installation and Maintenance Professionals
1.0 Scope and Objective
This specification establishes criteria for the labeling of certification programs for irrigation
system installation and maintenance professionals under EPA's WaterSense Program. It
applies to irrigation professionals who install new irrigation systems and/or repair and maintain
existing irrigation systems. The purpose of the label is to identify programs that certify irrigation
system installation and maintenance practitioners with demonstrated ability to apply water
efficiency concepts in their practice. An irrigation practitioner who holds a WaterSense labeled
certification should be capable of installing and maintaining irrigation systems with water
efficiency being a fundamental component of their practice.
2.0 Criteria for WaterSense Labeling
To be labeled under EPA's WaterSense Program, the certification program must meet the
following criteria:
2.1 Independent Oversight Committee
The certification process provided by an organization must be supervised by an
independent oversight committee. The oversight committee must be established by the
organization and be composed of at least three professionals who are recognized for their
expertise in the irrigation field. Employees of the certifying organization must hold no
more than one third of the oversight committee positions. The committee must be able to
exercise independent judgment and oversight to ensure the integrity of the certification
process.
2.2 Experiential Requirement
The certification must require that the applicant have a minimum of one year of
demonstrated experience in the field of irrigation installation and maintenance. In addition,
the professional must provide evidence of a working understanding of system
components, and the ability to disassemble, repair, and assemble system components.
The oversight committee must establish the documentation required to demonstrate the
experiential requirement has been met.
2.3 Exam Requirement
The certification must include a requirement for the successful completion of an exam or
series of exams. The exam process may include a written component, a field component,
or a combination of the two. Exam procedures must be established or approved by the
oversight committee.

2.3.1 Exam Content
The exam process should be structured so that passing practitioners must have
demonstrated proficient applied knowledge in the following subject areas and
their relationship to water efficiency (note: exam content is not limited to these
subject areas as they are provided as a minimum for recognition by
WaterSense):
• Knowledge of system components, system design layout and
equipment specifications particularly as they pertain to distribution
uniformity and system efficiency
• System maintenance
• Soil/water/plant relationships
• Precipitation rates and irrigation scheduling
• Impact of site conditions on equipment choice
• System hydraulics
• System pumps
• System pressure
• Equipment commissioning
• Blueprint reading and interpretation
• Awareness of other aspects of good practice, such as OSHA, and
electrical and plumbing codes, as well as the knowledge of when local
and state regulations supersede federal regulations.
• Recent innovations and technology developments
Specific exam questions should be established or approved by the oversight
committee.
2.3.2 Exam Passing Score
The oversight committee should establish the passing score. The passing score
on an exam must provide an objective level of assurance that the concepts listed
above are understood and can be applied by the practitioner.
2.3.3 Quality Assurance/Quality Control
The exam process must include the following QA/QC elements:
• The technical content of exam questions should be established or
approved by, and periodically reviewed by the oversight committee to
ensure that the exam meets the requirements specified in Section
2.3.1. In addition, an independent academic institution or professional
testing organization must review the exam questions to ensure that
they accurately test the subject material. The exam review process
should be conducted at least once every two years or every 1000
exams, which ever occurs first.
Version 1.0 2 October 20, 2006

• Exams must be administered by an independent academic institute, a
professional testing organization, professional test administrator, or an
irrigation professional certified in the subject matter.
• Exams must be graded by an independent academic institute,
professional testing organization, professional test administrator, or a
certified irrigation professional not involved in the training or proctoring
of the practitioner being examined.
• The security and integrity of the test questions and test processes
must be protected at all times.
2.4 Renewal Process
The certification must have a renewal process with a set periodicity.
2.4.1 Expiration
A certification must be renewed at least once every two years, or more frequently
as established by the oversight committee.
2.4.2 Maintained Proficiency
One aspect of the renewal process must require the submission of
documentation that the practitioner has maintained proficiency in the subject
matter (e.g. continuing education units). Documentation of maintained
proficiency must include evidence of the professional's ongoing application of
water efficient concepts in their area of certification. The oversight committee
should establish valid documentation requirements of maintained proficiency.
The certifying organization must either request submission of this documentation
or have an auditing process in place to ensure individuals are completing their
maintained proficiency requirements.
3.0 Application for the WaterSense Label
The organization seeking the label must submit an application to EPA's WaterSense Program
for review. The label will be granted upon the approval of an organization's application by
WaterSense staff. The application should document that the organization's certification process
meets the criteria listed in Section 2.0. The application must include the following materials:
3.1 Letter of Intent
The letter of intent serves to introduce the organization's certification program and should
include a background section that describes their certification and reason for seeking the
label under EPA's WaterSense Program. The letter should include a statement attesting
to the validity of information submitted, and be signed by the chairman of the oversight
committee responsible for the certification program and an officer of the organization.
