Boat Waste Disposal: Where Does It All Go?

where does boat waste go

Boat toilets, also known as 'heads', are an essential part of any boat, allowing people to go to the toilet when they need to, no matter where they are on the water. However, the waste from these toilets does not simply disappear. There are various types of boat toilets, each with its own way of dealing with waste. Some boats have portable toilets, while others have more permanent solutions, such as pump-out facilities that treat waste so that the water can be reused. With growing environmental awareness, composting toilets are also becoming more popular as they do not require chemicals or cause pollution.

Boat toilets are commonly known as 'heads'

When it comes to disposing of waste, it is technically allowed to dump raw sewage into the ocean once you are more than 12 miles from shore. However, it is always best to follow the laws of wherever you are. While at anchor, any waste you discharge will be pushed by waves astern of your boat. However, it is recommended to avoid discharging waste while at anchor and instead do it when you're offshore and underway.

There are various types of boat toilet, all of which work differently

The most common type of boat toilet is the "head", which is a fixed mounted toilet. However, there are also Coast Guard Certified Type I, II or III MSDs, which are not classified as heads but are also Marine Sanitation Devices (MSDs) according to the Federal Water Pollution Act. MSDs are defined as "any equipment for installation onboard a vessel that is designed to receive, retain, treat or discharge sewage, and any process to treat such sewage".

Boat toilets can be categorised as either cassette toilets or pump-out toilets. Cassette toilets have a removable waste tank and come in two basic forms: integrated (built into your boat as a permanent fixture) and freestanding. Pump-out toilets, on the other hand, require a pump-out facility to remove the waste from the boat.

Another type of boat toilet is the electric marine toilet, which is easy to use and intuitive. However, they can be unreliable, noisy and use a lot of power. They can also be challenging to use, as it is hard to know how long to press the flush button for, which can cause blockages.

A more environmentally friendly option is a composting toilet, which does not require any chemicals or cause any pollution. This type of toilet consists of two holding tanks, one for solids and one for liquids, and peat moss or sawdust is added to help the drying-out process.

Boat owners should carefully consider which type of toilet to buy for their boat. For instance, a pontoon owner might opt for a portable toilet, despite it not being a particularly nice option.

When it comes to discharging waste, it is recommended to do so when offshore and underway, following the laws of the territory in which you are located.

While at anchor, your boat will be facing bow to wind and, in theory, any waste you discharge will be pushed by waves astern of your boat. However, it is still best to avoid discharging waste while at anchor. Instead, do it when you're offshore and underway, and of course, follow the laws of wherever you are. For example, it is technically allowed to dump raw sewage into the ocean once you are more than 12 miles from shore, but this is up to the authorities of individual territories to oversee the regulations concerning their waters.
