Only in the USA! (or … so what about rat’s piss?)


Some eight million gallons of treated drinking water – yes, you read it right eight million gallons – have been flushed down the drain in the US state of Oregon after a man urinated into a reservoir. Was it really necessary to empty an entire reservoir because eight fluid ounces of urine?

“Nobody wants to drink pee, and I don’t want to deal with the 100 people who would be unhappy that I’m serving them pee in their water.” said David Shaff, a water bureau official in Oregon’s biggest city Portland, after flushing away 32 million litres of water, whilst completely ignoring the fact that fish and animals are continually peeing into the reservoir. Mr. Shaff clearly shuns human piss in preference to that of bears or beavers. Mr. Shaff and his colleagues took the draconian action after security cameras caught a twenty-one year-old man urinating into an uncovered reservoir. The water had already been purified and was to go directly to homes, which only serves to make the decision to empty it even more curious as passing birds doubtless poop in the water too. (birds don’t urinate).

But such a situation would never arise in the UK, for instance, because while most people think of reservoirs as outdoor lakes which are lovely to walk the dog around, all of the reservoirs containing treated water are covered. While public health experts in the US said the urine in the reservoir was so diluted that it posed little health risk, the Oregon water chiefs did not want to take any chances. Plus, the cameras also showed something, as yet unidentified, being thrown into the water.

Toxicologist Prof Alan Boobis is “flabbergasted” by what he says is a complete overreaction. “In a healthy person, urine is sterile. It’s something we can say with confidence – it’s not going to have any impact on anyone whatsoever.” He says even if chemicals were in the urine, they would not be in large enough quantities to cause damage. “We are exposed to chemicals all the time but the intake is already below a level that’s going to cause harm. Urine contains a whole range of substances that the body has no need for. It might contain chemicals that are potentially harmful but the levels are going to be very low when expelled by the body, and even lower when diluted by water.”

Prof Boobis, from Imperial College London, made the observation that the reservoir would already have contained fish and animal urine. “The water was treated, so some bacterial agent was already killing things,” he said “If someone urinates in a swimming pool, it doesn’t become a problem, and that is a much smaller body of water.”

Thames Water, the UK’s largest water and sewerage company, says all of its treated water reservoirs are covered to protect water quality, and the water is treated to stringent UK and European quality standards. Sue Pennison, from the Drinking Water Inspectorate, says that since 1990, it has not been permitted in law for a treated water reservoir in the UK to be open to the elements. “This is in order to protect supplies from contamination from many hazards, of which this example (human) is just one,” she adds. She says reservoirs containing treated water are emptied for inspection and cleaning every 10 to 15 years.

The urine donator in the Oregon case said he had been out drinking with friends and thought the reservoir was a sewage treatment plant.
