Moeller 28-Gallon Marine Waste / Holding Tank
A federally compliant marine sanitation holding tank built for boats where space is at a premium but capacity still matters. The Moeller 28-gallon tank is engineered to meet all federal material and pressure specifications for marine sanitation devices (MSD), with a nominal wall thickness of 0.30" (7.6 mm) specifically designed to contain odors that would otherwise permeate through thinner-walled tanks. It’s a straightforward, durable solution for boats that need a properly spec’d holding tank without the complexity of a full MSD system.

- 28-gallon capacity — suited to mid-size cruising and offshore boats
- Meets all federal material and pressure specifications for marine sanitation tanks
- 0.30" (7.6 mm) nominal wall thickness for effective odor containment
- Durable construction built for long-term marine installation
Compatible Applications
- Marine holding tank (MSD) installations on powerboats and sailboats
- Cruisers and offshore vessels requiring federally compliant waste storage
- Replacement holding tank for boats in the 25–40 ft range
- Installations where odor control and wall thickness are a priority
Parts Desk Insights
The 28-gallon size is a practical fit for mid-size cruising boats — large enough for extended offshore passages or weekend liveaboard use, compact enough to fit in most bilge or under-berth spaces. To complete a full holding tank system, you’ll need a macerator pump for pump-out: the SHURflo 3200-001 12V Marine Macerator Pump, Jabsco 12V Self-Priming Macerator Pump, and Johnson Pump 12V Macerator Pump are all compatible options. For a complete integrated MSD solution, the Jabsco Type III MSD Waste Management System includes both a holding tank and macerator in one package.
