According to the municipality, the objective is to obtain “contributions for the harmonisation of the city's nightlife”, to try to stop the phenomenon of drinking in public spaces, to control the sale of drinks and to reduce noise at night.
One of the measures of the amendment to the regulation is the use of hydrophobic paint, which protects walls and property by repelling urine against the offender.
The initiative had already been introduced by the Porto Chamber before the pandemic began, but in order not to contribute to the spread of Covid-19, it was suspended.
Contrary to what would be expected, the informal gatherings of groups drinking in public spaces intensified during the pandemic. With bars and clubs closed, drinks continued to be sold over the counter and one of the side effects of this was public urination.
Ana Cláudia Almeida, director of Movida, explained the measure of hydrophobic paint to the council at the last Executive meeting. Its application “will be reinforced”, as it is seen as one of the most effective solutions, according to a report by Jornal de Notícias.
The paint is already used in several European cities, to defend urban heritage, and repels urine against the offender, who is left with wet trousers and shoes. It also allows the sites to be easily cleaned by the municipality.

Well, what a shame for human beings to urinate outside in public. But the amount of dogs urine in my neighbourhood dwarfs the amount of dog urine that my neighbours allow their dogs to pee on our building walls....But I guess this is different:)?

or electrically charge the walls and video the results!

Speaking of sanitation, it seems our tax money might be better spent attending to the dog owners who do not clean up the city sidewalks after their dogs defecate. It's an obstacle course in downtown Porto.

More accessible public toilets might be better idea

generally there appears to be, football exempt, a progress deficit. instead of sanitation being a 'friendly appreciated' service they should jump straight to 'pay to pee' and plastic bag dog loo's' and see it as tourism business investment. perhaps a trip to york castle museum with its 'authentic' victorian clean streets would be helpful?

This sounds disgusting. Would be nice if a law was implemented that required people to pick up there dogs poop or be fined a large amount. It’s absolutely disgusting how people are too lazy and disgusting to pick up there dogs poop. Says a lot about a person that just lets there dog poop anywhere and not pick it up. You should not have a dog if you don’t want to pick up poop.

I think this is a great idea, men shouldn't be urinating in public streets in the first place, that's disgusting. As for dogs urinating, well that's what dogs are supposed to to. I do agree that dog owners should and must pick up their dog's poop. Pooper Scooper law is in most countries and it could easily be made law in Portugal too.

Another total waste of tax payers' money. Educating the population would be much better - and getting rid of all the stray animals roaming the streets and pooing all over. Time for the Portuguese to start obeying laws and keeping streets clean - and that includes not trashing, not littering and picking up their dogs' poo. There is NO excuse except laziness and being filthy people.

I wouldn't be surprised if the young American students lead the way in public drinking and urinating. They are champions at this kind of behavior.

My wife and I are currently holidaying in Porto for 1 week. The amount of night-time antisocial behaviour is very disappointing. There are groups of young people wandering up and down our street shouting and yelling all night long. It's impossible to get a good night's sleep.
Disappointed tourists from Northern Ireland.
