A series of visualizations were created for two companies. They both specialize in wastewater treatment systems.

One company is a municipal wastewater treatment plant, and the other company is a maker of biological water treatment fields with the help of the root system of the common reed. 

The municipal plant wanted to educate the residents about their activity in the municipality and to raise awareness about the importance of drinking water.

The other company wanted new visualizations to attract new clients to the company. They were targeting the homeowners. The graphics needed to be less technical and more approachable to the end-user - the family.

Both projects began similarly. We got together in person, and they showed me a former scheme they had of their processing plant. They described how the systems work and wanted an improved representation of how wastewater enters into the system, goes through various stages, and finally comes out as clean water into nature's water sources.

I started the task by drawing out the schemes with a pencil. It helped me get the idea out and determine approximate proportions and distances between objects on the paper.

Then I quickly painted over to see which colors would be appropriate and see the general feel and direction of the illustration. I then sent the sketches for evaluation if they have all the elements needed and if the graphic direction is OK. After confirmation, I made 3d models and positioned them in orthographic view to make it look more technical.

I rendered the model in white color and continued my work in Photoshop where I added all the textures and colors. I chose this route instead of adding textures in the 3d model because I intended to give the scheme more of a handmade feel.

After a couple of revisions, the work was finished and was published in a booklet which was not part of my assignment.
