"I was selling a 71 year old home and the inspection revealed a failing septic system. I had called another company as well as Bob snd had opted to use the other company which was local in Merrimack. Sadly I was told it would be 6 to 8 weeks. I could not wait that long since the house needed to be sold before winter. I called Bob and he began the same day! He explained he was also an engineer and could do the required septic design himself. He was able to have the entire job done in 2 weeks and we had a contract to sell before he finished. He was a delight to work with and I woukd recommend this company without any hesitation."

Septic Tanks questions, answered by experts

Installation necessitates professional expertise due to complexity and to ensure safety when handling waste.

The best bacteria to add to a septic tank is anaerobic bacteria, which doesn't use oxygen to break down solid waste. Because there is less oxygen in a septic tank, anaerobic bacteria can decompose sludge in a sealed environment. On the other hand, aerobic bacteria need oxygen and are prevalent in the leach or drain field of a septic system.

Septic tanks aren’t bad for the environment as long as they receive proper maintenance and attention. This means staying up-to-date with professional septic system inspections and septic tank pumping. Without regular maintenance, parts of the septic system could break or stop working, potentially letting harmful waste into the soil and groundwater.

Getting well water tested costs $100 to $350 if done by a pro. You can also buy DIY test kits for $20 to $100, but professional tests are more reliable. You can get a comprehensive well inspection, which includes advanced water testing, for $700 to $750, which you should do yearly anyway.

You can add three rotten tomatoes or 1/4 ounce of yeast to your septic tank to speed up the decomposition of sludge. You can add the tomatoes by way of your garbage disposal and the yeast by way of your toilet. You can do either of these additives once every three months as needed.
