"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 FAQs, answered by experts

Conventional anaerobic septic systems are the most cost-effective and least expensive type, with installation costs typically ranging from $3,000 to $8,000. For comparison, sand filter systems cost between $7,000 and $18,000, while mound systems are the most expensive at $10,000 to $20,000. Several factors influence the final price. The tank material is a key consideration; plastic tanks are the most budget-friendly option, starting around $2,900, but concrete and fiberglass tanks offer greater durability and longer life spans at a higher cost. The size of the tank also affects the price. For example, a 1,000-gallon tank costs between $900 and $1,500, whereas a larger 1,500-gallon tank costs $1,500 to $2,500.

A septic tank is an underground container that collects and holds wastewater until it’s sufficiently filtered and broken down. It treats wastewater by separating waste so the leftover liquid can travel into the drainfield where the soil and gravel eventually filter and purify it. This process naturally eliminates bacteria, viruses, and other contaminants.

Because well water is not artificially filtered or pre-treated, it may contain contaminants. As a result, it’s possible for well water to damage pipes based on what is in the water. Well water can be corrosive, slowly rusting and dissolving pipes, fixtures, and fittings. The corrosion can affect the taste and quality of the drinking water that comes out of the taps in your home. 

The smallest septic system available for purchase typically includes a 750-gallon tank. However, the smallest size you can legally install is determined by local regulations, and many areas require a minimum capacity of 1,000 gallons. The cost to install a small septic system generally ranges from $2,910 to $13,900. Before proceeding, it is essential to check with your local health department or consult a local septic professional to confirm the minimum legal requirements in your area.

Baking soda does very little to nothing for a septic tank, but it can help unclog a drain or clean out a garbage disposal. Rotten tomatoes and yeast are the best ways to increase the bacteria in your septic tank naturally. You can add these to your system once every three months.
