Septic Tanks questions, answered by experts

You can check your own septic tank, but take precautions. Locate the access lid, usually buried a few inches underground, and remove it carefully. Look for the sludge and scum levels, and if they’re high, that means pumping may be necessary. Check for odors, slow drains, or pooling water around the drain field, which could indicate issues. Never enter the tank, as toxic gases can be fatal. All of that being said, a professional inspection is safer and more thorough.

Your drain field or leach field should be 1 to 3 feet under the ground. It will be a little shallower than the septic tank, although it can be the same depth or slightly deeper. The proper depth of the septic tank is up to 4 feet. It’s possible that your local regulatory agency requires a certain depth for your drain field.

Deciding between an engineered septic system and a conventional one depends on property size, soil quality, local regulations, and environmental factors. If your property has limited space, poor soil, or is close to sensitive environmental features, an engineered system may be required. Professional site evaluations, considering water usage, long-term plans, and budget constraints, can help determine the appropriate choice. Consulting with a septic system professional is crucial for ensuring compliance with regulations and selecting the best system for your property's unique needs.

There are a few signs that you might notice if your drain field is bad. For starters, if you see standing water or soggy grass above your drain field, it could mean that it isn’t working correctly. Or, if your yard smells like sewage, it could also indicate that there’s a problem with your drain field. Repairing a drain field costs an average of $2,000 to $15,000.

With regular testing, treatment, and maintenance, water from a community well should be safe to drink. Unfortunately, the EPA does not regulate private wells, and contamination can happen. 

If you have doubts about the quality and safety of your drinking water, you have options for testing. You can pick up kits from your local home supply store or harvest samples and send them to a local testing facility. To get the most complete water quality testing and system diagnosis, seek a local well professional. They know what to test for and can recommend and implement a longer-lasting solution.
