Water Catchment Kauai North Shore, Hawaii
Locally owned, full-service water catchment for Hanalei, Princeville, Kilauea, Anini, and surrounding North Shore Kauai communities. Based in South Kona — serving all of Hawaii.
Kauai's North Shore — Hanalei, Princeville, Kilauea, Anini Beach, Wainiha, Haena, and the coastal stretch through Moloaa — is one of the most photographed coastlines in the world, and the property values here reflect it. Multi-million-dollar estates sit on lots that range from a quarter-acre Hanalei valley parcel to twenty-acre cliff-side ag lots in Kilauea, and the homeowner base is heavily weighted toward second-home owners, vacation-rental operators, and full-time residents who relocated from the mainland to be here. Many of these properties are off the Kauai County water main entirely — served either by well or by catchment — and the ones on county supply still benefit from catchment as a backup against pressure failures and main breaks in remote areas.
Annual rainfall on the North Shore ranges from about 70 inches in coastal Princeville to over 200 inches inland of Hanalei, with Mt. Waialeʻaleʻa (roughly 8 miles south) historically the wettest spot on earth at over 400 inches a year. That abundance is the easy part — what makes Kauai North Shore catchment design demanding is the combination of salt-air corrosion within a mile of the coast, the heavy organic load from dense mango, monkeypod, and albizia canopy, and the structural-design requirements imposed by exposure to north-swell winter storms and the occasional tropical system. Tanks here typically sit in the 8,000 to 20,000 gallon range because the year-round rain means storage capacity is not the constraint — water quality and corrosion resistance are.
For trophy-property catchment, the specifications we recommend on the North Shore go further than any other region we serve. Pioneer XL galvanized steel tanks with the AQUALINER Fresh NSF-61 antimicrobial liner — the same liner specified for high-end potable-water installations in commercial applications — are the standard, paired with V-LOCK panel construction rated for hurricane wind loads. Stainless steel fittings replace standard galvanized hardware on every property within a mile of the coast because salt air will pull rust through galvanized fittings within five to seven years. The 20-year Pioneer warranty applies here as everywhere else, but on properties where the homeowner reasonably expects 30+ years of service from the infrastructure, the warranty is the floor rather than the ceiling — these systems are routinely still performing well into year 25.

Location FAQ
Do you serve Kauai's North Shore for water catchment?

Is catchment common on Kauai's North Shore?
Yes — many North Shore properties are off the Kauai County water main entirely, served by well or catchment, and even properties on county supply use catchment as a backup against the area's occasional pressure failures and main breaks. The 70-to-200-inch annual rainfall makes the North Shore the most productive catchment environment in Hawaii.
What tank size do most Kauai North Shore properties need?
Most North Shore Kauai installations run 8,000 to 20,000 gallons. The year-round rainfall means storage capacity is not the constraint — water quality and corrosion resistance are. Smaller tanks are common because tanks refill rapidly; larger tanks are reserved for irrigation-heavy properties and full-residence sole-source applications.
Why do North Shore Kauai installs use stainless fittings?
Salt air within a mile of the coast — and the North Shore puts most properties inside that radius — corrodes galvanized fittings within 5 to 7 years. We replace every galvanized fitting with marine-grade stainless on coastal North Shore properties, which is the standard premium specification for trophy properties in this market.
How much does a water catchment system cost on Kauai's North Shore?
A complete Kauai North Shore system typically runs $16,000 to $34,000 depending on tank size, filtration tier, stainless-fitting upgrade, and Nawiliwili-to-Princeville freight cost. Trophy properties with hurricane-rated tank specs and dedicated fire-protection storage can run higher. Written quote after a free site survey.
