In Wädenswil there is the Rietliau sewage treatment plant, which purifies the water for the municipality of Wädenswil. It was put into operation in 1947 and has since been renovated again in 2005. The treatment plant is one of the medium-sized ones in the canton of Zurich, with a population equivalent of 44,000. The purified water flows back into Lake Zurich. There is a small recycling station for glass, plastic, etc. right in front of the treatment plant.

Gas heating systems have been around for a very long time and have been used for years. Natural gas is often used.
As soon as a building is too cold, this is reported to the boilers. There, gas burns. This produces heat, which is then transferred to the radiators with water. The radiators warm the rooms and then the cold water flows back and it is heated again.
Our Working Hypothesis
We think people want to have more green places in the cities but they dont have the time or knowledge to make it happen.
I couldnt find anything yet
I heard in the radio that the people in the cities wish more green places and bring back some life. (Like animals and flowers)
At the interview our hypothesis got confirmed.
The Apprentice said, that people actually dont do urban gardening, if they dont have time or the green thumb.

In Process...
Imagination
- People already doing some Urban Gardening without knowing.
- We want to show people how they can do their part and let them know a bit more
- bring back more green space to the cities
- spread the knowledge we gain out of this project
- motivate people to do some gardening with easy steps
Expetations
- I think it will be hard to do an interview on the street. It could be a struggle that people take their time and maybe the weather isnt good as well.
- For the Interview in the shop it could be difficult to find a shop were they are open to help or find a shop which has time for us.
- The survey could be a success. I know a lot of people also around the world, so we will be able to see different views all over the world to this topic.
- I can imagine that our plan might not work out and we spontaneously change our plans.
in progress
There are so many different problems, if we think about the environment and there are big inventions, when it comes to technology.
- But how can we help?
- how can we reduce our water?
- what can we do to renew energy, save and use it again?
- are we locally using renewable energy? Or don’t? How can we change it?
- can we plants trees?
- saving water is such a good thing we don’t even realize how much water we use and waste.
