"Scott Nelson was very prompt and responded to my situation quickly as I was in a bit of a panic. There was a hole developing under a sidewalk at the side of my house. He explained that it was an old redwood septic tank and he could fill it in properly and replace the pavers. He did all the work the very next day."

Septic Tanks FAQs, answered by experts

Trenches are typically 12 to 24 inches deep and 8 inches wide. However, the required depth depends on the specific project and local ordinances. For example, a French drain may need to be 18 inches deep, while a water pipe might require a depth of 24 inches and a drainage pipe 36 inches. Your city or county may have specific regulations, so it's wise to consult with an excavation professional to determine the correct depth for your project.

A mound septic system, when properly maintained, can last between 20 and 25 years on average—though some last longer or malfunction sooner than that. The most important part of maintenance is getting an annual inspection of the vital parts of the system to ensure they’re in proper working order and not too backed up with sewage.

Never use Drano on blocked toilets. You can end up with a ghastly leak because the chemicals eat away at the glue that holds pipes together just as effectively as they do with clogs. Drano is known for being particularly rough on toilets, which is why some plumbers actually dislike the product. 

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.

While abandoning a tank without treating it and following strict rules is illegal, there are several other ways to dispose of an old septic tank. One standard method is to pump out and crush the tank where it rests and bury it in the soil. Another is to remove it and transport it to a landfill. Finally, if abandonment is the best option, your contractor must pump out the tank and fill it with inert material, such as sand or concrete, depending on local regulations.
