SeaLand^® Holding Tank Systems (HTS)

Complete, reliable holding tank systems for use with VacuFlush® or other marine toilets.

Virtually any boat with room for a holding tank can now incorporate the advantages of Dometic’s premium-quality Holding Tank Systems.

Leak-proof Design

Top-mounted hose connections eliminate standing liquid in discharge hose, preventing odor permeation through hose.

Odor-free, Highly Durable Tank

100% virgin polyethylene resin with extra-heavy wall thickness prevents odor permeation and resists corrosion.

Implosion Protected

TankSaver® vacuum relief valve prevents damage from dockside pumps that use very high levels of vacuum.

ISO/USCG Compliant

SeaLand holding tanks fully comply with the ISO 8099:2000(E) standard and applicable U.S. Coast Guard requirements.
