Water Catchment Services in Kona, Hawaii
Locally owned, full-service water catchment for Kona and surrounding communities — the rainwater catchment Big Island homeowners have trusted since 2008. Based in South Kona, serving all of Hawaii.
Kona at a glance: the leeward (dry) side of the Big Island. Annual rainfall 20–40 inches from coast to coffee belt. Elevations from sea level to 3,000+ ft. Most homes use 15,000–25,000 gallon Pioneer tanks, plus an inline pH neutralizer in vog-affected South Kona zones. Pacific Blue Catchment is based in Captain Cook — you're almost always a same-day dispatch.
Kona sits on the Big Island's dry leeward coast, where annual rainfall averages just 20 to 40 inches — coastal Kailua-Kona is on the lower end of that range, and the upper coffee belt above Holualoa, Honaunau and Captain Cook can reach 40–60 inches in good years. Porous volcanic basalt below the surface means groundwater is scarce and expensive to access through wells, making rainwater catchment not just practical but essential for hundreds of homes and farms spread across the Kona coffee belt.
From Kailua-Kona's oceanfront neighborhoods up through Holualoa, Kalaoa, and the slopes of Hualalai, every property faces the same challenge: capturing and storing the rain that does fall. Pacific Blue Catchment has been designing and installing Pioneer water tank systems throughout the Kona district for over 15 years. We understand the unique demands of volcanic soil grading, salt-air corrosion near the coast, and the importance of proper filtration in an area where roof runoff picks up volcanic particulates and coffee-farming residues.
Our Kona installations typically include oversized first-flush diverters to handle the intense but brief afternoon showers common on the leeward slopes. Many of our Kona customers combine catchment with fire protection tanks — a growing priority as dry grassland fires become more frequent in West Hawaii's arid landscape.

Why does Kona's dry climate require a specific catchment approach?
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 Kona and what does not.
Which Kona neighborhoods does Pacific Blue serve?
Pacific Blue installs and services Pioneer catchment systems across the entire Kona district — coast to mauka. Subdivisions and neighborhoods we work in regularly include Kailua-Kona, Keauhou, Kahaluu, Holualoa, Kalaoa, Hōnaunau, Captain Cook, Honalo, Kainaliu, Hualālai Estates and the slopes above the coffee belt. Vog-zone protocols (calcite neutralizer, accelerated maintenance) apply across South Kona; salt-air protocols (stainless fittings, year-7 anode inspection) apply within ~1,000 ft of the coast.
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. NFPA 22 fire-protection installations require fire-marshal review. We handle the permit coordination as part of the project.
What do Kona homeowners ask most about catchment?
How much rain does Kona actually get for catchment?
Leeward Kona averages 20–40 inches per year. Coastal Kailua-Kona is on the lower end (around 20–25); the upper coffee belt above Holualoa and Captain Cook reaches 40–60 inches. Catchment is viable across the whole district with appropriately sized storage.
What size tank is recommended for Kona homes?
Most Kona single-family installs land at 15,000–25,000 gallons. Lower-elevation or smaller-roof properties may need 25,000+; upper coffee-belt homes with reliable orographic rainfall and larger roofs sometimes get by on 12,000–15,000.
Does vog affect catchment water in Kona?
Yes, especially in South Kona, Captain Cook and Hōnaunau. Catchment water tests at pH 4.5–5.5 in active vog conditions. We install an inline calcite or magnesium-oxide neutralizer between tank and house on every vog-zone job.
Are catchment permits required in the Kona district?
Standalone tanks typically don't trigger a Hawaii County building permit, but plumbing connection is permitted through Hawaii County DPW. Fire-protection installs require fire-marshal review. We handle coordination.
Which Kona neighborhoods does Pacific Blue serve?
All of them — Kailua-Kona, Holualoa, Kalaoa, Keauhou, Kahaluu, Hōnaunau, Captain Cook, the Hualālai slopes, and the Kona coffee belt. We're based in Captain Cook so most Kona-district jobs are same-day dispatch.
