Our Septic Drain Field had failed in two spots last year. Unsure how to payoff the cost of a new septic system ($17,000 - $20,000) At age 72 and knew nothing about my septic system, I began educating myself online about Septic Systems. I spotted Aero-Stream's advertisement in a side window and studied it several times. I also had several knowledgeable guys watch the video and they agreed with me that "it made sense!" We bought it, installed it and where nasty, stinky muddy areas in my yard were is now covered with new grass. And best part was the cost ... everything was less that $1,700. Thank you Aero-Stream for a wonderful affordable "fix" and for the best customer service I've ever received. I will e-mail Before & After pictures to Bob.
