About Us

Parjana was born in Detroit, Michigan in 2012. The company came alive to commercialize the Parjana system, first installed in 1997. Over a decade of monitoring, testing, and data review have provided the knowledge to make significant improvements to this amazing technology.

In the summer of 2024, Parjana Engineering proudly introduced IRIS. This new product design increases system infiltration rates by 15%, reduces materials and waste, and speeds up installation time over the Parjana system. These improvements not only enhance the performance of the system, but also decrease the carbon and ecological footprint making it an even more sustainable solution to water management problems.

 

Our Detroit-based team was originally drawn to the field of water management and to using groundbreaking technology by the water quality and water availability challenges happening in our home State of Michigan. Parjana Engineering is a data-driven company that has been monitoring projects for over a decade.
