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 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.
