About us: Accurate Onsite LLC was founded by Bill Walker and Andy Hill when Ohio's regulations were updated in 2007 creating a need for system designers. Our backgrounds, training & experience had prepared us to provide this service. We start with the results of a soil evaluation by a certified soil scientist and turn it into a site specific septic design—all sites are unique under the new rules. We live in Wayne and Ashland counties, but we also work a few counties further out—we've had thousands of designs approved by county sanitarians in 25 different Ohio counties. Typically, we work for current & future homeowners, installers, builders, small businesses, and government entities.

Our rates are from $900 and up depending on site & distance. Calling, texting, voicemail, or email is the way we'd like to hear from you—our office is your job site! Please contact us if you have any questions, we'll answer them, discuss the process and look at your soil reports and discuss your system options—without obligation. If you need soil scientists’ contact information we can happily provide it. Please, if you don't reach us leave a message—we will get back to you quickly!
