What People Are Saying

“We had Indigo Water Group administer an in-person class at our facility on microbiology, microscopy, and process control. The curriculum that was put together was immensely informative and has greatly helped improve our knowledge base to create better protocols and procedures. Being on-site, the training was even tailored to the specific processes of the attendees, making the content as relevant as possible. I cannot recommend Indigo highly enough.”

“Today I passed my Ohio Class 1 operator’s exam. Your courses were a tremendous help. It made the theory and maintenance portion a lot easier. It covered a lot of equipment that my plant doesn’t have and that I have never actually seen in person. I also scored well on the math portion thanks to your strategies and practice problems. I will definitely recommend your courses to anyone looking get their license.”

I have taken many of your wastewater classes. Your program is outstanding!  I have learned so much from you over the years

I am a student in water wastewater technology.  I have bought CD’s and searched the Internet for help solving water math problems.  Your site was over-the- top excellent!  Most sites do not use conversion units which makes the math difficult to understand. I wanted to let you know how much I appreciate your work.

I would just like to take a few moments of your time to thank you for putting those “big books of water and wastewater” on line. I am currently studying for my level 2 and hopefully then my level 1 later this year. I had been looking for something like these books – something that explains math in plain English. I’ve passed them out to anyone who was interested here at the wastewater treatment plant and everyone was quite impressed. So once again, a big THANK YOU!!!!
