This is a taboo subject but many researches have shown that urine is a very good plant fertilizer. If the subject is putting you off, continue to use your Solar-Dripper only with tap water, rainwater or commercial fertilizers.
But the information is free: your urine is good for your plants.
Urine is composed of 95% water with 2% urea containing nitrogen, then phosphorus, potassium, magnesium and many essential minerals for plants. The urine is odorless and sterile at first. We all produce 100 to 400 ml of urine about 5 times a day. At home it “disappears” with a flush of 8 to 15 liters of drinkable water and mixes with the rest to form smelly toxic sludge to treat.
This sanitary method alone uses about 18 cubic meters of water per year per inhabitant and it costs us € 72 / year in Annecy (€ 3.96 / cubic meter of water). Collectively in Annecy this represents more than 3.6 million cubic meters of water is the equivalent of about 14 cm of water taken from the lake. The bill for the 200,000 inhabitants is about 15 million € just for our urine.
> Special invitations to math teachers to check these calculations according to the types WC and to adjust to your local cost of drinkable water.
But taken separately initially, its agricultural use is common in Africa and India because it creates a free fertilizer, the 95% of water is valued and it avoids pollution and sanitary treatment of urine. Many green gardeners already do this near you by applying certain precautions.
Otherwise you can pay to buy an equivalent commercial fertilizer and pay also to treat your urine.
With the recent drought we decided to continue our experiments because the first tests were very conclusive just like in Africa. This technique of agricultural valorization in fertilizer is applicable also in Annecy, Geneva, Paris, NY, Monaco, Nevada, Moscow or Doubai. For many people, it seems foolish to mix the urine with the … and detergents to then treat (or not) the mains drainage. Not only are we wasting drinking water, but it is inappropriate because sanitation is more effective in the soil than in the water.
Without this “all in the sewer” method, the Seine would be swimmable in a short time and free of coliforms.
Fifty years after the fist man step on the moon, this major step for humanity is still not accomplished.
Apart from hippos, other terrestrial mammals do their thing on the ground and would never think of mixing urine and … in a pipe by creating ammonia odors. Even animals spontaneously give a paw to bury their material with leaves. Manure has been used for millennia by farmers because it produces beautiful vegetables.
Why not trying to use urine to fertilize your roses ?
Climate change exposes us to severe droughts or floods, and it is best to find solutions before the sewerage causes again more disasters. Yes it happened in Montreal, near Paris, In Marseille ou event in Annecy a magnificent green city.
The Solar-Dripper is more resistant to clogging than conventional drip systems. It permits biofilms and impurities of more than 2 mm to pass. You can use this precision dripper for fertilizer application in your plants or to use unfiltered rainwater. In addition the mixture is directed to 15 cm in the soil by the cone which protects the leaves and the fruits of a possible contact.
There is no health fear if you do it yourself with your plants.
This fertilizer application located deeply in the ground with the Solar-Dripper makes it more efficient than a surface application. It also reduces and eliminate odor emanation.
Make your free Eco-Fertilizer :
1- Get Solar-Dripper if you do not already have it. In Switzerland the Solar-Dripper is already in all Migros stores.
2- Urinate in a 1 L bottles with a wide opening of 38 mm or more. For the ladies, a “piss-upright” can facilitate the collection; some models are designed to directly fill a bottle with a 28 mm neck. Resourceful women will undoubtedly find the technical solutions. Scoop: this device called Lapee is available.
3- Add water to obtain a mixture of about 25 % urine. The rinsing water for your hands can be recovered also in the bottle. We tested mixtures between 10 to 100% of urine content without clogging problem or intoxication of the plant. According to a specialist engineer, Mr Renaud De Looze author of this book, a mixt of about 5 % or 1/20 is ideal in continuous use.
4- Put this solution in the bottle of Solar-Dripper filled between 50 % and 75 %. Apply as a normal watering. On corn, for example, a Solar-Dripper can be used on 4 plants and can receive 4 to 8 applications of urine in the season alternately with watering. For tomatoes, one intake per month is appropriate.

Let your friends know the results on twitter and help us to promote this eco awarness idea.
The results of this method have been convincing. Houseplants are greener and brighter. Flowering is enhanced, The corn grew very well and was D E L I C I O U S. You can use it at home, on the balcony and in your garden. It’s simple, free and odourless. As an ecological bonus, you save about 10 L of drinking water and recover the 95% water content in the urine. Start with flowers or trees if you worry about comestible plants.
Of corse, the idea is not to over-fertilise with free or commercial products and this procedure is to be used occasionally and not on a single place.
This example of useful recovery is a good news and much more appropriate than to collect toxic sludge and to return it (treated or not) in the rivers or in the sea. In addition to this proven method, you can also pour urine directly into your compost or in the bushes or the forests in complete eco-confidence during your walks. Using modern dry toilets is a more natural, appropriate treatment and deserves more development. It is much better than intoxicating the amphibians and making rivers prohibited for swimming . Endocrine disruptors or possible diseases are better neutralized by microorganisms in the soil than spread in the water.
In short, there are many solutions to use to convert a sanitary problem in a natural ressource.
By buying your Solar-Dripper, you use the latest R&D to preserve nature.
