The first open-air public urinal in San Francisco has been unveiled in the city's Delores Park.

The concrete circular urinal was opened in the latest move to combat the destructive scourge of public urination in the city.

And although it is in the open air, it does afford users some privacy as a screen protects the front of the urinal and it is surrounded by plants.

It has been described as a welcome addition to the park, which only had three toilets, leading to many people relieving themselves in bushes and on buildings.

Delores Park now has 27 toilets along with the urinal thanks to more than $20million in renovations.

They were the park's first upgrades in 60 years and the San Francisco Recreation and Park Department say they are unaware of any other cities with a public urinal.

Spokesman Sarah Madland said: 'Dolores Park has seen an exponential increase in the number of visitors: On a sunny Saturday, it can host between 7,000 and 10,000 people.

'One of the goals of the renovation was to address the littering and public urination issues that were rampant at the park.'

San Francisco has a long, sometimes creative, history of dealing with public urination. In 2002, the city increased the possible fine for the crime up to $500, but that did little to deter it.

Last summer, the city painted nearly 30 walls with a repellent paint that makes urine spray back on the offender.

Solar-powered toilets roll through city streets several afternoons a week. And city crews have inspected 10,000 light posts to make sure they won't fall over from erosion.

That comes after a three-story-tall light post corroded by a likely mix of human and dog urine, and weighed down by a large banner, toppled.

They clean and restock supplies and make sure people don't use drugs or sleep inside the restrooms.
