Professional Independence.  Shared Standards.  Elevated Industry Leadership.
​Uncle Tilo’s Clean Water LLC (UTCW) is expanding its statewide network of UTCW Water Partners to meet the growing demand for qualified, accredited rainwater catchment professionals across Hawai‘i.

UTCW Water Partners are independent business owners—not employees or contractors of UTCW—who choose to align with UTCW through professional listing and education standards. This model strengthens the credibility of individual businesses while raising the bar for the entire rainwater catchment industry in Hawai‘i.

Who UTCW Water Partners Are
UTCW Water Partners are:

• Independent businesses operating under their own Hawai‘i State business license
• Professionally listed on the UTCW website as qualified Rainwater Catchment Professionals
• Committed to education, health awareness, and recognized industry standards

This affiliation allows homeowners, real estate professionals, and communities to easily identify trusted, ARCSA-accredited professionals in one centralized, reliable location.

Who We Are Looking For
We are seeking established professionals who take clean water seriously and want to be part of a statewide effort to improve water quality outcomes for those on catchment systems.
Ideal UTCW Water Partners include:

• Licensed Plumbers operating in the State of Hawai‘i
• ARCSA-Accredited Professionals
  (Intro to Rainwater Harvesting required; advanced coursework encouraged)
• Professionals actively working toward ARCSA accreditation
• Field technicians with experience in:
  • Rainwater catchment systems
  • Water treatment and filtration
  • Pumps, pressure tanks, and plumbing infrastructure
  • System evaluations, maintenance, and troubleshooting

Equally important are professionalism and character. UTCW Water Partners are expected to communicate clearly, act ethically, and respect the health implications tied to water quality.

What UTCW Water Partners Do
Depending on individual qualifications and services offered, UTCW Water Partners may provide:

• Catchment system evaluations and maintenance
• Water testing and system diagnostics
• Filtration and treatment installations
• Support for homeowners managing private water systems
• Field services related to real estate transactions involving catchment systems
• Catchment Inspection Reports (CIRs), where qualified

All listed professionals are expected to align their work with ARCSA/ASPE/ANSI Standard guidelines and best practices for rainwater harvesting systems.

Why Be Listed as a UTCW Water Partner
UTCW Water Partners choose to advertise their services on the UTCW website because it is recognized as a trusted education and resource platform for rainwater catchment in Hawai‘i.

Benefits of being listed include:

• Visibility on a respected, award-winning local website
• Association with a brand known for education and integrity
• Connection to a growing audience of informed homeowners and real estate professionals
• Alignment with recognized standards and continuing education
• Participation in elevating Hawai‘i’s rainwater catchment industry as a whole

This model preserves professional independence while fostering shared standards, accountability, and credibility.

Training, Accreditation, and Expectations
ARCSA accreditation is strongly preferred and, in many cases, required for listing.
UTCW Water Partners are expected to:

• Maintain current ARCSA accreditation or actively pursue it
• Keep their Hawai‘i business registration in good standing
• Stay informed through continuing education
• Represent the profession—and the UTCW platform—with integrity

This opportunity is not entry-level. It is intended for professionals who are serious about specialization, education, and leadership in the field of rainwater harvesting.

What This Opportunity Is Not
Becoming a UTCW Water Partner is not:

• Employment with UTCW
• Casual or short-term work
• A sales-only opportunity
• A fit for individuals unwilling to follow established standards

This is a professional affiliation built on trust, education, and responsibility.

How to Express Interest
If you are a licensed plumber, ARCSA-accredited professional, or actively pursuing accreditation—and you want your business listed among Hawai‘i’s trusted rainwater catchment professionals—we invite you to start a conversation.
