"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

You should never park or drive on top of a septic field. Vehicles can weigh upwards of two tons, and this weight can put a lot of pressure on the leach lines in the drain field. Too much pressure on your leach lines may cause them to warp, crack, or completely burst. This is an expensive and very avoidable problem.

With regular testing, treatment, and maintenance, water from a community well should be safe to drink. Unfortunately, the EPA does not regulate private wells, and contamination can happen. 

If you have doubts about the quality and safety of your drinking water, you have options for testing. You can pick up kits from your local home supply store or harvest samples and send them to a local testing facility. To get the most complete water quality testing and system diagnosis, seek a local well professional. They know what to test for and can recommend and implement a longer-lasting solution.

You can put yogurt in your septic tank, but it will not increase the bacteria in your septic tank. In other words, it won't harm your tank, but it won't get rid of a septic smell or boost the performance of your septic system. While yogurt contains helpful bacteria, you would need to buy an extraordinary amount of yogurt to make any difference. Adding yogurt is not a helpful or cost-effective strategy.

The water refills in a well through gravity that draws water from the water table to fill the vertical hole. The pump brings the fresh water through a pressure tank and to the pipes in your house. The well continues to refill indefinitely as long as you don’t use more water than the well is producing.

While not strictly necessary for your septic system to operate, septic tank risers are a highly beneficial and wise choice for homeowners. They provide easy access to your tank, which makes regular maintenance, inspections, and addressing issues significantly easier and less labor-intensive. By eliminating the need for repeated excavation to locate the tank, risers can save you money, labor, and energy in the long run. This easy access allows you to proactively manage your septic system, addressing potential problems before they become costly and ensuring the system's longevity. Additionally, some local regulations may require risers, and installing them can help you avoid potential fines or penalties.
