What Is the Big Deal with Flushing Toilet Paper?

 Toilet paper is generally made of either paper or a combination of paper and cardboard. Toilet paper is specifically designed to wipe away solid waste and clean your delicate areas. Toilet paper dissolves in water and can often be flushed. This requires an advanced system of drains and wastewater processing facilities though.

These wastewater processing facilities make sure that the dirty water doesn’t get in the local rivers as this can cause a lot of problems. If these facilities have to process toilet paper as well, they have to be more advanced and this requires a big investment. 

 Not every country or city has this advanced system. This might be because the country is quite large or because they decided to invest the funds somewhere else.  

In some areas of the world, the width of the drains is not big enough and toilet paper would clog them. Wastewater would back up and make the toilet overflow.

This can result in wastewater all over the house. Next to bad smells, it also results in a dirty house. When those pieces of toilet paper break down, they create a very thick, sludgy substance that winds up jamming your household pipes and the local sewage systems. When these materials enter the sewer system, they cause major problems. 

In some instances it can be removed by flushing a lot but this is not always the case. A plumber will have to come out to clear the drains with a water jetter or an auger. This costs quite a lot of money. If there is a big clog, it might be needed to dig up the drain and open it up. 

This is a lot of work and can result in a big expense. This is why restaurants and hotels in Lisbon are warning you that it isn’t allowed to flush toilet paper. You might get in trouble if they catch you doing it anyway.
