After talking to Dave about your system, you sent me all the pages of info and tech data to give to my county health dept. I was oked to use your system due to property has a creek running thru it and not enough property to run a conventional septic leachfield. System was easy to install and when we had it approved by the county they came and certified it. They were amazed at how well it air-rated the septic system(which was installed in original tank). also imoressed with biobruch and filter system. Thank you for saving me around 15000 dollars to install what their original engineer designed for the property. Great service answered our questions as we were installing the system and great follow up. will recommend to anybody and my contractor was also impressed and will be calling you for kits at his next jobs. thanks so much, Jeff Treadwell
