Customers say: True professional

"Paul and his team (Tom, Miguel, and Jason) were all very personable, knowledgeable, and efficient. Paul saved us from what could have been a long and perilous sewer permitting and installation process and instead designed a simple, effective in-ground septic system. Tom and his crew did the installation expertly and quickly, and brought us in under budget. They even spread the extra stone from the job on our stone driveway! It was a pleasure to work with everyone involved."

"The job which was complicated replacing 2 Old Cesspools with tanks and a drain field. They gave me a date months out but showed up as scheduled. They handled all the permit work and left me with a freshly seeded lawn that came up great. This is a family business generations old. I was very pleased with a job well done. Highly recommended !"

"RCM came to reconstruct our draining system, as well as remove an oil tank from our front lawn. The draining system along side of our home was done very efficiently and so far has been operating beautifully. The oil tank in our front lawn was a lot more work than anticipated. To our surprise, the tank was larger than expected but Bob and his team adapted to the situation and took care of what needed to be done. Overall, Bob is very skilled in his line of work, and he and his team have done a great job with all of the work they’ve done for us. Would hire again!"

Septic Tanks FAQs, answered by experts

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.

Talking with a septic pro before planting trees near your tank is best to ensure the roots won’t interfere with your septic system. However, there is an easy way to figure out where to plant a tree—but you’ll need to know how tall it can get when it’s fully grown. For instance, if the tree can reach 50 feet, plant it at least 50 feet from your septic system.

Saving money on property taxes and having direct control over your waste system are both pros when buying a house with a septic tank. However, it’s easier on the house and the yard if a home can be hooked up to a municipal system, which is why septic tanks are best for homes where that isn’t an option. Expensive repairs, potential odor issues, and regular maintenance are all cons of septic systems. 

The efficacy of a drain field depends on a wide variety of factors, though a well-maintained one can last as long as 40 or 50 years. Of the different types of septic tanks on the market, concrete and plastic tanks tend to last the longest—upwards of 40 years if they’re pumped regularly—while steel tanks have a tendency to rust over time and may need to be replaced after 15 or 20 years.

They can if they’re not installed correctly or if the caps or covers were dislodged by a lawn mower or other yard equipment. This is why it pays to hire a reputable septic tank company that’s experienced in septic tank installation and maintenance. You should also check caps and covers often to see that they’re in place and take measures to tighten or secure them, provided it is safe to do so.
