Hilo Water Catchment Installation and Repair
Locally owned, full-service water catchment for Hilo and surrounding communities. Based in South Kona, Kona — serving all of Hawaii.
Hilo at a glance: windward Big Island, the wettest city in the US. ~130 inches of rain per year, with upper-elevation areas (Waiakea, Panaewa, Kaumana) over 150 inches. Catchment is extremely productive — most homes run 10,000–20,000 gallons of storage. Commercial-grade filtration, oversized first-flush and high-output UV are mandatory in Hilo's tropical environment.
Hilo holds the distinction of being the wettest city in the United States, receiving an average of 130 inches of rain per year — and significantly more in the upper elevations toward Waiakea and Panaewa. This extraordinary rainfall makes water catchment systems remarkably productive, but it also places extreme demands on gutters, tanks, and filtration equipment that must handle daily downpours lasting hours at a time.
In Hilo's lush windward environment, catchment systems face challenges that dry-side installers rarely encounter. Rapid algae growth, leaf debris from the dense tropical canopy, and high humidity mean that tanks without proper screening and UV treatment can quickly develop water quality issues. Pacific Blue Catchment builds Hilo systems with heavy-duty gutter guards, oversized inlet screens, and commercial-grade UV sterilization units designed for the volume of water these rooftops collect.
Many Hilo properties also contend with older galvanized or fiberglass tanks that have degraded in the constant moisture. We specialize in replacing aging systems with modern Pioneer tanks that resist the corrosion and biological growth common in Hilo's warm, wet climate. Whether you are in downtown Hilo, Keaau, or the subdivisions along the Hamakua coast, our crew delivers fast turnaround on installations and emergency repairs.

Why does Hilo's heavy rainfall require specialized catchment design?
Salt air, volcanic conditions, heavy rainfall, and remote locations — we have built and maintained catchment systems across every microclimate the islands throw at us. 15 years of local knowledge means we know what works in Hilo and what does not.
Which Hilo neighborhoods does Pacific Blue serve?
Pacific Blue installs and services Pioneer catchment systems across the Hilo bay area and out into the surrounding districts. Neighborhoods we serve regularly include downtown Hilo, Waiakea, Panaewa, Kaumana, Keaau, Hawaiian Acres, Fern Forest, the upper Hilo subdivisions toward Mauna Kea, and the Hamakua-coast properties leading north to Honokaa. Every Hilo install gets the high-rainfall package — Smart Water Saver, oversized first-flush, commercial gutter screens, 30+ mJ/cm² UV.
Permits and code: standalone catchment tanks generally don't require a Hawaii County building permit, but plumbing connection to the dwelling is permitted through the Hawaii County Department of Public Works. We handle permit coordination as part of the project.
What do Hilo homeowners ask most about catchment?
How much rainfall does Hilo get for catchment?
Hilo averages roughly 130 inches per year — the highest urban rainfall in the US. Upper Waiakea, Panaewa and Kaumana exceed 150 inches. Catchment is extremely productive; the engineering challenge is handling the volume cleanly.
What size tank is recommended for Hilo homes?
10,000–20,000 gallons covers most single-family demand. Hilo homes can run smaller than dry-side properties because the rainfall is so reliable.
Why do Hilo systems need heavy-duty filtration?
Dense tropical canopy + warm humid environment = constant organic debris and accelerated algae/biofilm growth. We spec commercial gutter screens, oversized first-flush, and 30+ mJ/cm² UV on every Hilo install.
Are old galvanized or fiberglass tanks worth keeping?
Usually no. Hilo's moisture corrodes galvanized from both sides; aging fiberglass leaches resin breakdown. Pioneer Zincalume + AQUALINER Fresh replacement is almost always the right call.
Does Hilo require permits for catchment systems?
Standalone tanks typically don't trigger a building permit, but plumbing connection is permitted through Hawaii County DPW. We handle the coordination.
