What is a chemical wc?

When it comes to getting a caravan or motorhome, or planning a nature camp, a very important topic is the chemical toilet. Some caravans and motorhomes bring it as standard (Fixed Toilet) and others not as for example the custom vans (camper), so you have to get one (Portable Toilet).

If you are thinking about entering the world of camping you may not have thought of some situations (especially with children) in which you may find yourself in the middle of a trip, such as having a squeeze. You may be in the middle of nature, and you are attracted by the idea of being in contact with it, congratulations, you do not have any problem! :D. Just find a place more or less apart and a couple of leaves (or stones) to clean yourself.

On the other hand, if you are more classic and prefer to do your needs in a hygienic and neat place, you probably want to have one of these chemical toilets at your fingertips. Although another solution would be to have a plastic urinal, being able to trip over it, or worse, to put the foot in the middle of the night by an oversight, so this solution could be discarded.

In this article we are going to talk about the types of chemical Wc, its parts, components, smells and its functioning. You can also have a look at the article about the advantages and disadvantages between caravans and motorhomes.

Types of chemical wc

There are 2 types of chemical toilets.

Fixed chemical toilet: They usually have a greater capacity, of about 20 L approximately. These toilets are incorporated into the caravans/autocaravans themselves and have external access via a trapdoor (slightly larger than that of petrol) to the sewage tank and the cistern tank.

Portable chemical Wc: This toilet has a smaller capacity, about 15 L approximately. It has the utility of being portable and being able to take it where you need.

Parts of the chemical wc

Black water tank: It is the compartment where we make our needs and these are undone with the chemical product.

Tank tank: Here is deposited the pink liquid that provides good odor and disinfects (which we will discuss later) or water for what is known as “flush”.

Trampilla: It divides the cubicle of the black waters with the entrance to the same one. Serves to keep the strong odor (of chemicals) separated from the outside.

Toilet cover (Tip: open it before using, and close it after)

Capacity indicator: It can be a light or a coloured plastic that will indicate when the tank is reaching its maximum capacity.

Types of liquids

Blue liquid
Place: Black water deposit
Function: Chemical for decomposition of waste (essential)
Quantity: Normally 1 stopper for every 10 litres of water, and in summer a little more for the high temperatures (consult the product label).

Pink liquid
Place: Tank Depot
Function: Disinfects, removes lime, gives good odor to the cup and creates a sliding layer on the cup (not essential)
Quantity: Tank tank capacity

Tank emptying​

The right place to empty the tank is the chemical bathing area that you can find in campsites, camping areas and service areas. Keep in mind that for this end, it is possible that you have to respect a certain schedule to empty the tank.

It is advisable to empty the tank with gloves that protect us from the chemical elements of the blue and pink liquid. It is also not superfluous to say that going with shoes/sneakers will always be more advisable than going in flip-flops in case we have any problems with splashes.

To take the tank of our vehicle to the emptying area, it is advisable to use (many toilets and bring them from factory) a cart with wheels to make us more bearable the road with the water on our backs.

Once emptied, the tank must be filled with water (with the usual hoses in these areas) and emptied again. Repeat this process until the water comes out clean.
