Molokai Water Catchment Systems
Sustainable Rainwater Systems for the Friendly Isle
Pacific Blue Catchment brings proven water catchment expertise to Molokai, the Friendly Isle. From the lush East End valleys to the dry West End plains, our Pioneer Tank systems deliver reliable water storage solutions for this rural island community. With limited county water infrastructure and dramatic rainfall variations across the island—from over 300 inches annually in East Molokai mountains to less than 20 inches on the West End—rainwater harvesting provides essential water independence for Molokai homeowners.
Molokai Water Storage for Island Self-Sufficiency
Rainwater Collection Across Diverse Climates
Molokai’s unique geography creates distinct rainfall zones requiring customized water catchment approaches. East Molokai receives abundant precipitation, with upper elevations collecting 100-300+ inches annually, while West Molokai and the Hoolehua Plains average just 20-35 inches per year. This dramatic variation makes proper system sizing critical for water security.
Pacific Blue Catchment understands Molokai’s water challenges and designs systems to maximize collection in your specific region. Our corrosion-resistant Pioneer Tanks handle the island’s varied conditions—from East End’s tropical humidity to West End’s arid climate—while providing dependable water storage year-round.
Most of Molokai’s rural areas lack county water service, with the Department of Water Supply serving limited portions of the island. Many communities rely entirely on catchment systems, wells, or trucked water for daily needs. Even where municipal water exists, service is often limited, making catchment essential for property development and agricultural use.
Molokai Water Tanks Built for Island Conditions
Premium Storage for Every Molokai Region
Our Molokai water storage systems feature advanced Zincalume steel construction engineered for rural island environments. Whether you’re in the rainforests of Halawa Valley or the dry plains of Hoolehua, our tanks withstand extreme rainfall variations, salt air, and agricultural demands while maximizing every drop.
System sizing depends on your specific location and needs, but all locations can have custom tank sizes from 3,000-200,000+ gallons:
East Molokai (Halawa, Pukoo, Waialua): 10,000-35,000 gallons
- High rainfall (100-300+ inches in mountains)
- Lush tropical environment with heavy organic debris
- Consistent precipitation supports smaller storage ratios
- Acidic water conditions require corrosion-resistant materials
Central Molokai (Kaunakakai, Kualapuu): 15,000-40,000 gallons
- Moderate rainfall (30-50 inches annually)
- Mixed residential and agricultural use
- Balanced systems for year-round reliability
- Limited county water access
West Molokai (Maunaloa, Hoolehua Plains): 20,000-65,000+ gallons
- Lowest rainfall (15-25 inches annually)
- Extended dry periods require maximum storage
- Agricultural irrigation increases capacity needs
- No county water infrastructure
Our Pioneer Tanks include built-in pre-tank filtration systems handling Molokai’s varied debris—from East End’s tropical vegetation to West End’s dust and agricultural particulates.

Advanced Filtration for Agricultural Environments
Complete Water Treatment Systems
Molokai’s rural character and agricultural heritage require specialized filtration approaches. East End properties face heavy organic matter from lush vegetation, while all areas benefit from systems designed for agricultural and household use. Our systems include:
- Multi-stage sediment filtration for organic debris and particulates
- UV sterilization systems eliminating 99.9% of bacteria
- Carbon filtration for taste enhancement
- Pre-tank mesh screening minimizing debris entry
- Corrosion-resistant materials for acidic East End water conditions
Smart monitoring systems provide real-time data on tank levels, pH balance (optimal 6.5-8.5 range), and water quality indicators, essential for rural properties without immediate service access.
Investment Value for Molokai Homeowners
Long-Term Water Independence
Water catchment delivers exceptional value for Molokai properties. With minimal county water infrastructure, catchment systems often provide the only viable water source. Trucked water costs can exceed $200-400 monthly, making catchment systems financially essential rather than optional.
For properties with well water, catchment provides crucial backup during mechanical failures or drought conditions. Many Molokai homeowners combine catchment with well systems, achieving complete water security while reducing dependence on expensive trucked water deliveries.
Initial investment in a properly sized catchment system typically pays for itself within 6-10 years through eliminated delivery costs. After payback, property owners enjoy decades of free water collection while increasing property value and agricultural productivity.
Our premium Zincalume steel Pioneer Tanks last 200% longer than standard galvanized alternatives, providing superior long-term value with minimal maintenance. The 20-year warranty ensures your investment is protected through the island’s varied climate conditions.

FAQ SECTION
Why is water catchment essential for Molokai properties? Molokai has limited county water infrastructure, with most rural areas completely unserved by municipal systems. East Molokai receives 100-300+ inches of rainfall annually while West Molokai gets only 15-25 inches, making properly sized catchment systems essential for water security. Many properties rely entirely on catchment or expensive trucked water.
What size Molokai water storage tank is right for my location? Tank sizing depends heavily on location. East End properties often need 10,000-35,000 gallons due to high rainfall, while West End and Hoolehua properties benefit from 20,000-65,000+ gallons due to arid conditions and agricultural needs. We provide free site assessments to determine optimal sizing for your specific property and water requirements.
Can Molokai water catchment systems handle the island’s extreme rainfall differences? Absolutely. Our Pioneer Tanks are engineered for Molokai’s dramatic climate variations. East End systems include enhanced filtration for heavy organic debris and corrosion-resistant materials for acidic water conditions. West End systems maximize storage capacity for extended dry periods and agricultural irrigation demands.
Does Molokai require permits for water catchment installation? Yes, Maui County requires proper permitting for tank installations on Molokai. Pacific Blue Catchment handles all permit applications, inspections, and compliance requirements, ensuring your system meets local regulations and DOH guidelines specific to rural island properties.
What maintenance do Molokai water tanks require in agricultural areas? East End systems benefit from quarterly gutter cleaning due to heavy vegetation debris. West End agricultural properties need regular dust and particulate filtration. All systems require annual filter replacements, UV lamp servicing every 12-18 months, and bi-annual tank inspections. Our Pioneer Tanks’ built-in filtration significantly reduces maintenance compared to standard systems.
