Sani-Loo® Holding Tanks are made to fit your boat and your particular needs.
Holding Tanks.
Sani-Loo® Holding Tanks are custom-made to suit you vessel and to complement the Onboard Sewage Treatment System.
They can be fabricated to your specifications using a range of materials, including stainless steel. Please discuss your needs with your representative.
A Sani-Loo® Level Control Switch (HTLS) is recommended. When used with the Sani-Loo® Control Box, it will automatically shut down the toilet when the holding tank is full, preventing sewage from being pumped out the vent.

The Sani-Loo® Level Control Switch can also be supplied to fit existing installations.
