"Vic and his crew are very professional and Vic explained all of the problems that he encountered while installing a new septic system. They cleaned up the area when they finished and graded the soil and put down grass seed and straw. I highly recommended them!!!!"

"I contacted Great Bear through Angie's List and they were very responsive. Calling them to set an appointment was a little bit more difficult - but maybe because I called early. I called again and got through and made an appointment. Due to a backup in appointments, they were unable to come the first time around, but said they would come the next morning. They came on time then and discounted the rate since they were unable to make it the previous day. I wasn't there in person, but my husband dealt with Mike the owner and said he was friendly, professional and put the dirt with grass back over the hole (which the previous septic company we dealt with had not even tried to fix). Will definitely hire again in the future."

Septic Tanks FAQs, answered by experts

There are three layers of wastewater in a septic tank: scum (solid waste that floats to the top of the wastewater), liquid (the relatively clean liquid wastewater in between the two other layers), and sludge (solid waste that falls to the bottom of the wastewater). The buildup of sludge is one of the main reasons septic tanks need to be pumped. If the tank is more than 1/3 of the way full with a combination of sludge and scum, it’s time to call a pro for pumping.

Many variables, such as home size, type of engineered system, the material used, soil conditions, and water usage, dictate how long your system will last. On average, most homeowners find that their system lasts 15 to 20 years, though it’s not unheard of for them to last up to 40 years with annual and preventative septic maintenance.

The best way to keep a septic tank clean is to hire a local septic tank cleaner to inspect and pump the septic tank every three to five years. Be sure to only flush human waste and toilet paper down the toilet, and don’t pour grease, oil, fats, coffee grounds, or food scraps into your drains.

To keep your septic tank healthy, be careful of what you flush and be conservative with water usage, as even flushing too much water down the drain can throw off the septic system’s delicate balance. Never flush anything but human waste and toilet paper down your toilet, and be sure to have the tank inspected and pumped every two to five years, depending on the size of your household and your water usage.

Ensuring you have adequate space for your engineered septic system is crucial. You’ll need to reserve approximately 900 square feet for a three-bedroom home’s system. However, the type of soil you have, soil absorption rate, the size of your home, climate, and local zoning code will impact the actual amount of space you need.
