His ancestors were all millers; his great-grandfather erected in 1902 the first hydroelectric power plant on the Große Mühl river, which still stands and operates to this day.

Joachim Eckl's views on the art and culture are therefore strongly influenced by the close connection of the humanity with the mysticism of the water.

In 1997, together with the German artist Klaus Rinke, Joachim Eckl started a series of collaborations, with the most prominent opus being the design of the Pro Kaufland Shopping Mall in Linz.

[10] In July 2017 the exhibition "Bleaching Time" for the Textile Center of Haslach[11] and in September 2017 "River Talks" in the Chapel on OK-Platz in Linz took place.

[13] The Lentos Art Museum in Linz helped to organize this project by Joachim Eckl, with a total of 60 teams each drawing 1,000 liters of water from the Danube, which were combined in containers, in order to create a unique sculpture that would display the amount of water that flows through the human body during the whole average human life span.

[14] Joachim Eckl has created the permanent art installation "Landing spot for arrivals" at the entrance of the hotel and restaurant Mühltalhof,[15] which is located on the banks of the Grosse Mühl and is known for the "Mühlviertler" natural kitchen on the haute cuisine level.
