"Designed and installed new septic. Job was challenging (water table, very rocky digging). Did an excellent job, and worked with me to use rocks and boulders dug up to finish grading/landscaping nicely. Very happy with work."

"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 FAQs, answered by experts

The disadvantages of having a well include more maintenance, like annual testing and inspections, and high up-front costs to drill a well. Well water is also vulnerable to contamination, which is why keeping up with testing is important if you own a well. When it comes to well water versus city water, well water does offer more independence and is a reliable water source.

Several signs can indicate a faulty well pump pressure switch. These include your pump running continuously, the pump not turning on at all, or a sudden and complete loss of water. Other symptoms are weak water pressure or an erratic, unpredictable water flow from your fixtures. If you notice these issues, the pressure switch may be the cause. Testing the switch can help diagnose the problem. A faulty switch will likely need to be repaired or replaced. If the issue is more complex, it's best to consult a professional well technician to ensure your water supply is restored correctly.

A septic tank riser should extend to just above the ground level or slightly above it. The exact height can vary depending on local regulations and personal preferences, but a common guideline is to have the riser's top flush with or no more than a few inches above the surrounding ground. This height allows for easy access to the septic tank without creating a tripping hazard or obstructing mowing and landscaping activities. It's essential to ensure that the riser lid is easily visible and accessible for regular maintenance and inspection while being mindful of safety and aesthetics.

Your septic tank naturally contains the good bacteria it needs, so you typically don't have to add more as the system produces them on its own. However, if you wish to replenish the bacteria, you can use natural methods. For example, you can add three rotten 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 additives are unnecessary and may even harm your system. The most effective way to maintain a healthy bacterial balance is to avoid using chemical drain cleaners, which can kill the beneficial bacteria in your tank.

The average cost to replace a septic tank or install a new system is typically around $7,350, with a broader average range of $5,000 to $12,000. However, total project costs can vary widely, from $5,000 to as much as $22,500. Key factors influencing the price include the size and type of the septic system, the tank material, and the size of your house.

It's important to distinguish between the cost of the tank itself and the cost of the entire system installation, which is significantly more. For the tank alone, costs vary by size:

  • A tank for a one-bedroom house typically costs $500 to $900.

  • A 1,000-gallon tank, suitable for most one- to three-bedroom homes, costs between $900 and $1,500.

  • A tank for a five- or six-bedroom home generally costs $1,200 to $1,600.
