"Leo went out of his way to meet my concerns about cost, collaboration with my neighbor, and how the fence would look. He submitted multiple bids giving me options as to how to do it and at what cost. He tailored his approach to my needs. His team was easy to work with. The team worked quickly, efficiently, and throughly. The fence looks great!"

Septic Tanks questions, answered by experts

A septic tank is an underground container that collects and holds wastewater until it’s sufficiently filtered and broken down. It treats wastewater by separating waste so the leftover liquid can travel into the drainfield where the soil and gravel eventually filter and purify it. This process naturally eliminates bacteria, viruses, and other contaminants.

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.

There are many potential causes of low well water pressure. The most common include sediment buildup, leaking pipes, a failing well pump, or a cracked pressure tank. 

On average, you should call a pro to pump your cesspool once per year. If you have a larger home with a lot of family members, you may need to pump more (up to six times per year). On the flip side, if you’re talking about a cesspool for a home you don’t use much or if you’re the only occupant in a home, you won’t have to pump nearly as much.

Depending on the size and location of your septic tank repair job, you may want to let the septic pros finish before tackling other backyard work. However, in some cases, it’s not a bad idea to coordinate between your providers if the timing’s right and your septic repair pro says it’s safe to do so. For instance, if the septic repair work is happening in the fall, you might want to take advantage of the opportunity to prepare your backyard landscaping for winter , or in spring, start mulching the garden beds.
