"Couldn't be happier with the service we've been receiving from Great Bear Septic over the years. They are professional, take the time to answer our questions, and are unfailingly cheerful. They are a pleasure to work with. When we first purchased our home ten years ago, we had Earthcare take a look at our system. They tried to talk us into a $20,000+ replacement of our system. Something didn't seem quite right, so on the recommendation of friends, we reached out to Great Bear. Ten years later, with regular pumping from Great Bear, system still works great. In addition to all their other fine qualities, the team at Great Bear is trustworthy! Could not ask for more."

"Pumped out septic tank. Everything from scheduling to the actual pumping went well. The driver/worker was very knowledgeable about keeping a healthy supply of bacteria and enzymes in the tank."

"As a real estate owner/broker and homeowner. Billy does all of our septic inspections and necessary repairs for my real estate agency and its clients. His thoroughness and attention to detail are outstanding. I am confident when I recommend him to my clients. He has even performed his services on my property, installing a septic tank and fields. The septic tank was under a manicured landscaped area with pavers, stone walls, and steps between my house and garage, with very limited access. He actually built a ramp for the machines to traverse the stone wall to access the site. Removed the old septic tank, installed the new one, and put everything (including plants he had to remove) back in the same place. I can't believe it looked like it never happened. I recommend Billy to everyone I encounter who needs septic or drainage work."

Septic Tanks FAQs, answered by experts

French drains, sump pumps, and exterior waterproofing systems are common options. Choose one that best suits your property’s needs.

Common signs that a septic tank is full include plumbing issues, odors, and changes in your yard. You may notice wastewater or sewage backing up into your home's drains, or that sinks, tubs, and toilets are draining slowly. Gurgling or bubbling sounds from the pipes are also a key indicator. Outside, you might smell foul sewage odors around your house or the septic tank area. Look for pooling water, spongy soil, or a marshy environment around the drain field. Another tell-tale sign is a patch of grass over the septic system that is suddenly lusher and greener than the rest of your lawn. If you notice any of these signs, you should contact a septic professional for an inspection and pumping.

Wells typically replenish at a rate of about five gallons per minute, but several variables can influence how quickly they refill. A deep well will take more time to replenish than a shallow one. The replenishment rate can be slowed by issues such as leaks, damage, a faulty well pump, or a clogged well screen. Other factors, such as the surrounding geology, regular precipitation, and proper maintenance, also affect the recovery rate.

Yes! Toilet paper can be flushed if you use a septic tank. While unique toilet papers designed to be used with septic tanks are available, many people have no problem flushing regular toilet paper with a septic tank, so long as you don’t flush too much toilet paper all at once. Do not flush any type of baby wipes or bathroom wipes, even if they say “flushable.”

The bacteria already present in your septic system should be enough to break down solids in a properly maintained septic tank. However, if you’re in a DIY mood, you can try adding (well-mashed) rotten tomatoes to help the good bacteria fulfill their duty. Just make sure you give them a couple hours to work after flushing them down.
