"The service technician was 2 hours late and his price was $1900, I decided to get a second quote and I am so glad I did. I got the same job done with better tank and filter for $1100. My advice is get a second quote if you have time, I saved $800 by using another company."

"I hired them because they said they could pump my septic AND snake my drain. They did pump my tank very nicely, they were available when I needed them, and they were able to identify a problem immediately. However, what they meant by snaking the drain is that they could send another person out for an additional fee to snake the drain. I was also only quoted for the pumping and not the snaking so I ended up paying double what I thought I was going to pay. I also found out AFTER the first payment/job that they had a military discount so that was a little disappointing, but I am very grateful that it was applied to the second payment/job."

Septic Tanks questions, answered by experts

The ideal depth of a septic drain field is 18 to 36 inches below the surface. The trenches must be deep enough to allow proper wastewater distribution and filtration while remaining shallow enough for oxygen to reach the soil, promoting bacterial activity that helps break down contaminants. In areas with high groundwater or poor drainage, shallower systems like mound drain fields may be required.

A septic tank lid is often 1 foot underground, but it could be just 4 inches from the surface or 4 feet deep. For septic tank lids that are closer to the surface, you’ll have an easier time locating them just by looking for signs in the yard or using a metal probe. But for septic tanks that are buried deeper underground, you’ll need to hire a pro with specialized equipment to track down the lid without risk of damaging utility lines.

A septic tank riser features a base ring that you need to install flush to the opening of the septic tank. After thoroughly cleaning the opening of the tank, fit the base ring over the opening and use a butyl sealant rope to create an airtight seal with the tank’s rim. Cut the riser rings to the appropriate height and stack them on the base ring. Then, install the riser lid. This task might be taken on by an experienced DIYer, but you should always call a septic tank professional if you are unsure of your skills.

The price you’ll pay for service from a septic tank company will depend on the specific service you need. Here are some common services, along with average pricing:

  • Anaerobic septic system installation: $3,000–$8,000

  • Aerobic septic system installation: $10,000–$20,000

  • Septic tank pumping: $250–$550

  • Percolation test: $700–$2,000

  • Leach field installation: $2,000–$10,000

These numbers vary based on your septic system size, property layout, and more, so the best way to get an accurate estimate is to contact a septic tank professional for a custom quote.

Ideally, you should conduct a mechanical inspection and a bacterial or well water inspection yearly. While you might be able to push it off to every other year, it’s best to have peace of mind, especially when it comes to something that you use so frequently. 

If you experience repeated gastrointestinal illness in the household, it's important to test the well water more regularly for quality and cleanliness to check for bacteria.
