Why would an otherwise rational Private Developer choose to
partner with a government agency in Hawai‘i on an infrastructure
development project?
Sometimes, the Project just makes too much sense, despite all the
apparent (or perceived) obstacles – this can be a formula for a
WIN/WIN/WIN project.
WHY? – INDEED (THE
DETAILS).
 Kaua‘i Lagoons Resort and the County have long
had a Contract under which the Līhu‘e WWTP R-2
Effluent is the source for the Golf Course irrigation
water supply
 30-year Agreement executed in 2001 for up to 1.5
MGD
 The Agreement specified R-2 Effluent water quality
 Kaua‘i Lagoons Resort’s development plans
necessitated upgrading water quality to meet R-1
requirements
 The logistics and future operation considerations of
doing the Upgrades at the Līhu‘e WWTP were
quicker easier and less costly than the alternative
BENEFITS FOR THE
DEVELOPER
 No commitment of land and resources for a separate
wastewater facility, which would have been
necessary with a stand-alone “polishing plant”
 Permitting additional treatment at an existing facility
much easier than permitting a new wastewater plant
 Solids handling, filter backwash and backup or “offspec” effluent disposal issues much more
straightforward
 The improvement is considered a contribution of
wastewater treatment capacity, qualifying for an
offset of County’s “WTCA” fee for new development
($3.1 million)
 Negotiated an increased reservation of capacity
BENEFITS FOR THE COUNTY
 Upgrade to R-1 facility is consistent with County’s
strategic goals and objectives
 County CIP resources not tasked with the project
design and construction – ultimately saving money
for County and our rate-payers
 Rapid execution of the Project, compared with
typical County project execution timeframe
 Project design robust and expandable, a foundation
for expansion of R-1 system for multiple other future
users
 ENVIRONMENTAL AND SUSTAINABILITY
BENEFITS

LESSONS LEARNED/CONCLUSIONS
 This Project is a successful example of a Public –
Private Partnership. Key elements:
Well capitalized, motivated developer willing to work
positively with the community and to “run with the ball”
 County agency recognizing opportunity for mutual
benefits and to allow different style of project execution
 Assembling experienced professional team for the
Project
