![enter image description here][1] **Important stocks and flow in my neighbourhood:** * Food supply. * Supply of high quality water. * Supply of electricity. * Transportation. * Temporarily: Material flows and stocks during the work on the new drainage infrastructure in my neighbourhood. **Description of several stocks and flows:** * Food: Supermarket is just 200 meters away from my home. Every day in the morning there are transports with products to the supermarket, the flow. From the numberplates you can see these are international transports. Products can stay several days or weeks as stock in the supermarket and eventually find their way to the locals in a radius of about 5 kms, the flow. *Water: High quality water is one of the most important things in the city. There can be a flow from the stock to the user to be used immediately (cooking, washing, drinking) or a flow to a smaller in-house storage tank, to be heated and used as warm water stock. The first stock is the reservoir at the plant just outside the city, it flows through underground pipes to the city into the homes, there it could be used or be stored, when used it will flow through the sewer system back to the plant to be purified. *Transport: The local parkinggarage or the public parking lot is the stock, from which people leave in the morning to work and come back in the evening, the flows. There is not enough parking space. *Temporary Materials: A new drainage systems is being installed in my neighbourhood. On the **picture** you can see the preparation of a material stock for the work. The flow of drainpipes, concrete, sand and gravel comes in from the factories all over the country and will be stored untill used for the work. **Some future possible changes in stocks and flows:** *Food: Instead of international products put a new concept in place of local products. This will keep transport costs low with a smaller carbon footprint and stumulate local economy. A change in flows. *Water: In the Netherlands, in my city and in my neighbourhood is an abundance of rainwater. A solution could be the construction of local storage in undergound tanks for this railwater which can be used when drinking-quality water is not necessary, like for flushing the toilet. This will reduce the flow of high quality drinking water from the plant and make the system more sustainable. Less energy, less Co2. *Transportation: in the evening the flow of cars returns to the neighbourhood, stock is piling up, there is just not enough parking space. The government tried to get more peaple into the public transport, but did not succeed, so a bigger central parking garage is needed. The only available spot is under the green heart of this neighbourhood. Making room for a bigger stock. [1]: https://edxuploads.s3.amazonaws.com/14176353609058236.jpg
