Septic Tanks FAQs, 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.

You may want to increase the size of your leach field, for instance, if you add on to your home or install more bathrooms in your house. You can make your leach field larger by installing more pipes or expanding the area of the field itself. Improving the soil quality in the drain field can also make it more effective without increasing the area.

A new water well pressure tank costs $300 to $500. If you choose to hire a plumber for the job, expect labor to cost $125 to $200. If the tank is difficult to access, labor will cost more. Diaphragm and bladder well pressure tanks have similar costs. One-compartment well pressure tanks are less costly, but they have a higher chance of waterlogging. Larger pressure tanks cost more and hold more water, but they don’t increase water pressure.

Mound systems can fail if foreign objects are flushed into the septic tank, the septic tank is backed up with solid waste (sludge), if wastewater floods or seeps from the mound, or if any part of the system is clogged. To prevent this, only flush toilet paper and your normal “business” down toilets, and get a septic inspection at least yearly.

Septic distribution boxes, also called D-boxes, tend to last over 30 years if taken care of extremely well. In most cases, however, they tend to last anywhere from 15 years to 40 years. Regular cleaning and maintenance, as well as living in an area that doesn’t flood the tank or the system regularly, will all have an impact on the lifespan of the box.
