"I was very pleased with the people I worked with to complete this project. I had an issue with my septic pipes and JCB informed me of the best way to address it, gave me a very reasonable estimate and stuck to it, even though they had to do more than they anticipated, including drilling through my foundation. I would highly recommend this service!!"

"I had a wonderful experience with Delfino construction. They have completely transformed my house and property with a new drainage system and sump pump rendering my basement to be DRY! Also a new septic tank and leech field along with beautiful rock walls and U shaped driveway. The knowledge and attention to detail made our whole experience very comforting we couldn’t be happier with the turnout. Thankyou so much!"

Septic Tanks questions, 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.

While you can drain water softener backwash into a septic tank, doing so may cause several problems. One problem is that increased sodium chloride levels from water softener backwash can kill septic tank bacteria, decreasing the effectiveness of this wastewater treatment system. Another issue is that large calcium deposits can eventually stop up the drain field and lead to poor drainage. 

You can add three rotten tomatoes or 1/4 ounce of yeast to your septic tank to speed up the decomposition of sludge. You can add the tomatoes by way of your garbage disposal and the yeast by way of your toilet. You can do either of these additives once every three months as needed.

Options include submersible, jet, and centrifugal pumps. Choose based on water needs and well depth.

Your septic tank naturally contains the beneficial bacteria it needs to function, so you typically don't need to add more. However, if you wish to replenish the bacteria, you can use natural methods. For example, you can add three overripe tomatoes to your garbage disposal or flush 1/4 ounce of active yeast down the toilet every three months. While store-bought septic enzymes and chemicals are available, many experts consider them unnecessary and potentially harmful. The most effective way to maintain a healthy bacteria population is to avoid using chemical drain cleaners, which can kill the good bacteria in your system.
