WaterSense® Specification for Irrigation System
Installation and Maintenance Certification Programs
1.0 Scope and Objective
This specification establishes criteria for the labeling of certification programs for irrigation
system installation and maintenance professionals under the U.S. Environmental Protection
Agency's (EPA's) WaterSense program. It applies to certification of 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 installation and maintenance
professionals who demonstrate the ability to apply water efficiency concepts as a fundamental
component of their practice.
This specification should be read in concert with the WaterSense Professional Certification
Program Labeling System, which includes requirements that all programs shall meet.
2.0	Criteria for WaterSense Labeling
To be labeled under the WaterSense program, a certification program shall meet the following
criteria:
2.1	Experiential Requirement
The certification shall require that the applicant have a minimum of one year of
demonstrated experience in the field of irrigation system 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 shall establish the standard of proof for the experiential
requirement.
2.2	Exam Requirement
The certification shall include a requirement for the successful completion of an exam or
series of exams that encompass the content and passing-score requirements outlined
below. The exam process may include a written component, field component, or
combination of the two.
2.2.1 Exam Content
The exam process should be structured so that passing practitioners shall 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 earning the WaterSense
label):
• Knowledge of system components, system design layout, and
equipment specifications, particularly as they pertain to distribution
uniformity and system efficiency.

Water Sense
•	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 U.S.
Occupational Health and Safety Administration guidelines, electrical and
plumbing codes, and when local and state regulations supersede
federal regulations.
•	Recent innovations and technological developments, including
WaterSense labeled technologies.
2.2.2 Exam Passing Score
The passing score on an exam shall provide an objective level of assurance that
the concepts listed above are understood and can be applied by the practitioner.
2.3 Renewal Process
The certification shall have a renewal process with a set period for validity and specific
requirements for maintenance of proficiency as outlined in this section.
2.3.1	Expiration
An individual's certification shall be renewed at least once every two years, or
more frequently as established by the oversight committee.
2.3.2	Maintained Proficiency
The renewal process shall require the submission of documentation that the
practitioner has maintained proficiency in the subject matter (e.g., continuing
education units). The professional certifying organization (PCO) shall
demonstrate that a minimum of 50 percent of proficiency requirements are
related to water-efficient concepts in the field of irrigation (see Section 4.0). The
oversight committee shall establish valid documentation requirements of
maintained proficiency. The PCO shall either request submission of this
documentation or have an auditing process in place to ensure individuals are
completing their maintained proficiency requirements.
3.0 Effective Date
This specification is effective as of July 24, 2014.

4.0 Definitions
Independent Oversight Committee: A committee established by the PCO that supervises the
certification program while exercising independent, professional judgment. This committee shall
act as a governing body for the certification program and be responsible for establishing policies
and requirements. It shall be composed of at least three professionals who are recognized for
their expertise in the relevant professional field. No more than one-third of the positions may be
held by employees of the PCO.
Irrigation System Installation and Maintenance Professional: An individual who installs new
irrigation systems and/or repairs and maintains existing irrigation systems.
Water-Efficient Concepts: Any concept directly related to best practices in the field of irrigation
that promotes more efficient use of water outdoors. These include, but are not limited to smart
scheduling technologies for irrigation systems, irrigation scheduling based on water budget
techniques, drip irrigation, plant water demand, rainwater harvesting, and low impact
development. The following concepts are examples of those that shall not be considered as
water-efficient concepts: electrical systems, renewable energy, business practices, marketing,
or nutrient/pesticide management.
