Moeller Water & Waste Tanks
When it comes to reliable marine water and waste containment, Moeller's tanks are constructed from linear low density polyethylene (LLDPE), which offers higher tensile strength and greater impact- and puncture-resistance than many other plastics. This advanced material selection ensures that whether you're storing freshwater for extended cruising or managing waste in compliance with federal regulations, your onboard systems can withstand the demanding marine environment season after season.
Each Moeller water tank is manufactured at their factory in Sparta, TN, using resin that meets FDA specifications for polymers used in contact with food, ensuring safe, odor-free water. This commitment to quality construction means boaters can trust their freshwater supply remains clean and potable throughout long voyages. The same engineering rigor applied to Moeller's industry-leading fuel systems translates directly to their water and waste tank offerings, bringing over 25 years of rotational molding expertise to every product.
For waste containment, Moeller designs tanks to meet Federal Regulation 33CFR159, which incorporates EPA standards for water pollution control. This regulatory compliance is essential for boaters navigating protected waters or operating in jurisdictions with strict environmental requirements. The durable LLDPE construction resists degradation from chemicals commonly found in marine sanitation systems, while the precision molding process ensures leak-free performance and proper integration with pumps, vents, and deck fittings.
Moeller Marine utilizes rotational molding, blow molding, foaming and assembly processes to create custom-engineered marine products that stand out for their industry-leading quality, outstanding reliability and durability. This manufacturing versatility means that whether you need a compact freshwater tank for a center console or a larger holding tank for a cruising yacht, Moeller can deliver solutions optimized for your vessel's layout and capacity requirements. The rotational molding process produces seamless, one-piece construction without welds or joints that could become weak points over time.
Beyond standard configurations, Moeller offers custom tank design services for boat builders and serious refitters who need tanks shaped to fit unusual spaces or specific installation requirements. This flexibility, combined with the same material quality and regulatory compliance found in off-the-shelf products, makes Moeller a preferred partner for both production boat manufacturers and individual boat owners seeking reliable water and waste management solutions that will perform reliably for years to come.
