Septic Tanks questions, answered by experts

Rainwater doesn't have a direct impact on the amount of water in your well. Instead, the majority of rain runs off into other bodies of water such as streams, rivers, and lakes. These bodies of water may sometimes function as the area’s reservoir and create aquifers, which then help to replenish your well.

Yes. A septic tank riser is meant to replace a septic tank cover—concrete, metal, fiberglass, or otherwise—while still allowing easy access to the opening of the tank. Just as you would need to be mindful of the septic tank lid when it comes to mowing the lawn or other yard usage, you’ll have to be cautious not to damage or otherwise disrupt the septic tank riser.

Some of the signs that could mean your water is contaminated, such as cloudiness or bubbliness, could also be non-problems that don’t affect your water’s potability. However, if your water smells or tastes strange, it’s a good idea to stop drinking it and test it immediately. If your well water is contaminated, the best way to discover that is to test it.

How often you need to pump your tank depends on the size of your tank and how many people live in your home. The average recommended frequency is every three to five years. However, your tank may need more or less frequent pumpings than that. For example, a single person with a 1,000-gallon septic tank may only need to pump it every nine to 12 years, while a five-person family with the same sized tank may need to pump it every two to four years.

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.
