"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."

"When they checked the outlet baffle we discovered that a portion of the concrete blocks in the wall of the septic tank had crumbled. At that point we decided entire septic system needed to be replaced. Jim & Dan did a very professional job in removing old tank, installing the new tank, and digging three new leach fields. They were careful with surrounding trees and bushes, did a good job of restoring yard and planting new grass."

Septic Tanks FAQs, answered by experts

Septic tank odors can happen because of a few different issues with your septic system, such as a full tank, clogged drains, or blocked venting systems. Not only is a smelly septic tank pretty unpleasant, but it can also pose a potential hazard to yourself and your home. Toxic fumes could be hanging around, or untreated wastewater could be harming the environment.

You can cover a septic tank riser with dirt, but it’s not always the best idea. If you have a plastic riser and you bury it, you can easily lose track of it since you won’t be able to find it with a metal detector. Make sure to clearly note where your rise is in your yard so that you’re able to access it easily the next time you or a septic pro needs it. Don’t bury the cover too deep or you could place too much stress on it and make it too difficult to access in the future.

The average cost to replace a septic tank or install a new system is typically around $7,350, with a broader average range of $5,000 to $12,000. However, total project costs can vary widely, from $5,000 to as much as $22,500. Key factors influencing the price include the size and type of the septic system, the tank material, and the size of your house.

It's important to distinguish between the cost of the tank itself and the cost of the entire system installation, which is significantly more. For the tank alone, costs vary by size:

  • A tank for a one-bedroom house typically costs $500 to $900.

  • A 1,000-gallon tank, suitable for most one- to three-bedroom homes, costs between $900 and $1,500.

  • A tank for a five- or six-bedroom home generally costs $1,200 to $1,600.

A septic tank always has some amount of liquid in it—which should usually be 8 to 12 inches from the top of the tank. If the liquid level is higher than that or is overflowing the drainage pipe that leads out to the leach field, the tank may be too full and in need of pumping.

Certain foods are easier on your septic tank than others. Septic-safe foods include yogurt, fruit, cooked veggies, and bread because these items all break down relatively easily and can pass through your system safely. Rotten tomatoes, specifically, are actually good for your septic tank because they can increase the amount of good bacteria in the system.
