"I just pay $75 you never know who's going to come out. They do everything electrical. Just about everything is covered except the septic tank. I had an air conditioner replaced. It went great, all I had to do was pay for the freon. He didn't charge e more than what was needed."

Septic Tanks questions, answered by experts

The main difference between a mound septic system and a conventional one is that the drain field in a mound system is built up into a mound composed of sand and gravel to increase the filtration time the wastewater sees before it is returned to the aquifer. There’s also a significant cost difference, with mound systems typically costing far more than standard septic systems.

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.

You may notice a septic smell in your yard after it rains if groundwater is entering your septic tank and causing it to overflow. If you experience septic odors after rainfall, contact a licensed plumber. They can construct a drain to redirect rainwater away from your septic tank. 

There are many reasons you may want to extend the depth of an existing well or drill a new, deeper well on your property. A deeper well can tap cleaner water sources—shallow water may contain more contaminants. With a deeper well, you’ll also have an easier time reaching the water table depth (the level at which underground water is found) and can get past tricky soil conditions. 

Plus, if your local building code requires a minimum well depth for safety and environmental standards, you’ll meet the code by digging a deeper well in the first place.

A septic smell may be harmful because sewer gas is dangerous depending on the exposure amount and length of time. Sewer gas is made up of multiple gases, including hydrogen sulfide, methane, ammonia, and carbon dioxide. Some of these gases, like hydrogen sulfide and ammonia, are toxic to humans and can be fatal in high concentrations or long exposures.
