"Steve is very knowledgeable and efficient on the installation of a new septic with pump. He cares about how he leaves the landscape when he is done and greatly improved how things were before. Not to mention the best price we received."

"John Bensavage did an excellent job of repairing my septic system which included replacing the septic tank. To gain access to the tank they had to have five trees removed. John coordinated the tree removal subcontractor as well as removing and replacing the septic tank. He also repaired the broken waste pipe leading to the septic tank. Throughout the whole process every phase of the job was performed on in a timely manner and every delivery of material arrived on site exactly when needed. John's crew was excellent as well, performing each phase efficiently and smoothly while while exercising great care to avoid damaging the adjacent structure. I enjoyed watching how smoothly they worked together. When the job was finished, they expertly restored the surrounding landscape to a condition better than it was before. John kept every promised date and time and accomplished the job exactly when he said he would. I highly recommend John H. Bensavage LLC to anyone in need of septic system repair. And John was the lowest bidder."

"The technician emptied the freezer, which was in the basement, to work on the part that needed repair. Then he neglected to put anything back into the freezer, including a turkey I had bought for Christmas and a rack of ribs. Two days after he left, I went out of town for two weeks. The turkey actually exploded and spewed its liquid all over everything, which had to be discarded. I let AHS know and they couldn't even bother to call me or follow up on this. I'm considering not renewing my contract with them because of the quality (or lack thereof) of many of the providers they send."

Septic Tanks FAQs, answered by experts

You can find your septic tank using a few different methods. For one, you can check your property records at your local municipal office. You can also inspect your yard looking for a depression, a septic tank lid, or lush septic-area vegetation which would indicate a leach field. You can also follow your pipes from the home to the yard. If you can't find your septic tank on your own, a local septic pro can help.

The best times of year to pump or empty a septic tank are spring and fall. Many professionals recommend spring because the ground has thawed, making the tank easier to access, and any snowmelt or rainfall can aid in proper drainage. Pumping before summer is also ideal to avoid conflicts with vacations or outdoor gatherings.

Fall is another great option, as contractors may be less busy than in the spring. Servicing the tank in late fall or early spring can also reduce the risk of overflow from extra precipitation during winter and spring.

While summer is a possibility, winter is generally not recommended. The ground is often frozen, which can make it difficult to access the tank, and the waste inside may also be frozen.

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.

The physical constraints of hand-drilling a well limit the depth you can achieve. Manually digging with picks and shovels may only lead to shallow wells of up to 60 feet in depth. To reach greater depths, you need more specialized equipment. The diameter of your well and the tools you’re using will determine how far down you can dig.

A cistern works by collecting rainwater from your gutters and downspouts and storing it in a holding tank. The holding tank can be installed above or below ground, and the size will depend on your household needs. The stored water can then be used for household tasks, watering your garden, and even for drinking water.
