Waste Holding System

Type III MSD: ZDS-10

A Type-III MSD may be used aboard any vessel regardless of size or geographic location. The system receives waste from one or more toilets and retains it for disposal at a dockside or marina pump-out facility, or the contents may be pumped directly overboard where legal to do so.

Available in many sizes and shapes, but stocked in standard sizes, GROCO’s Type-III MSD system comes complete with a TLM series level monitor and a powerful (17 GPM) macerator/discharge pump located inside the tank.

ZDS Models include SweetTank™, which keeps the holding tank odor-free at all times, without the use of chemicals or filters. SweetTank can be added to older ZDS Models.

All tanks include an oversized vent to aid with high-capacity dockside pump-out.

IMPORTANT NOTE: It is illegal to discharge untreated waste directly overboard in most places. Consult local regulations before doing so. Discharge restrictions change with geographic location.
