About Sanitation Systems

We design, sell, and install the most reliable and odor free systems possible. We can spec a system for a small runabout with a simple head to a sophisticated waste treatment system on a multi passenger vessel. The most important element of the system is how the system is plumbed. If a sanitation system is plumbed improperly then toilets will fail, clogging and odors will become a problem. Our philosophy is simple; eliminate standing waste everywhere in the system.

Sanitation systems must move the waste efficiently from the toilet to the point where the waste leaves the boat or problems will occur sooner rather than later. We recommend that all toilets be plumbed directly to a holding tank with no vented loops or valves in the line. Ocean going vessels should have a waste pump and a deck discharge fitting. Vessels on inland waters can skip the pump if the vessel never has a chance of seeing the ocean. The deck discharge and the overboard pump should each have their own dip tube (or pick up tube) in the waste tank, once again no T’s or three way valves should be in either of these lines. Direct connections make installing and operating the system very simple. We’ve seen countless times where the valve positions have been confused, and have lead to clogging and overfilling the waste tank. These are problems that NO ONE wants to fix.

See our Holding Tank schematic

We use dip tubes (pick-up tubes) instead of a fitting located at the bottom of the tank. Dip tubes eliminate having standing waste accumulate in the discharge line as the tank fills. Dip tubes maximize the volume by emptying the tank with very little residual waste left in the bottom; this ensures constant flow through the system.

The waste pump should be at the highest point in the overboard discharge line, this allows any residual waste in the lines to drain back into the tank or overboard through the seacock when the pump stops running. We meet the U.S.C.G. regulations by using a key switch for the waste pump. The Coast Guard requires that a sanitation system be secured while a vessel is less than three miles offshore, we meet this requirement by using a key switch on our waste pump. This allows the operator of the vessel to “lock” the system from discharging overboard.

Any toilet will perform to its maximum capability if the waste handling part of the system is set up as described as above. We can supply all the components of a good functional waste system from toilet to seacock including the expertise.
