We had a 50 year old concrete septic tank and the top collapsed. The local public health department and the Ohio EPA determined which type of tank was needed to replace the old system. Our home is situated above a steep slope with limited access to the back of the property where the tank had to be located. There were some other physical-location factors that made the installation difficult. Bedrock Earthworks LLC was chosen because they were on the public health department's list of approved installers, and they gave a reasonable bid to install the very expensive tank. The new tank was ordered and when it came in, the installers arrived when they said they would. The old tank was pumped out, collapsed and filled in. They installed everything in a short time. The health department came out and approved the installation. We worked with Bobby at Bedrock Earthworks LLC and he was knowledgeable and helpful. They were extremely efficient and professional. We would highly recommend Bedrock Earthworks LLC. read more
