"I had my sewer hooked up from the septic to the city sewer. I got quotes from 5 different contractors and Anthony gave my the best quote by far. His team came to my house and in less than a day the job was done. I was very pleased with the job they did and would highly recommend them to anyone."

"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!"

"The guys from Dennis Diffley assessed the cause of the issue right away, went above and beyond in helping me locate where the plumbing clean out was located (I purchased my home with a finished basement), and educated me through every step of the process to help me prevent the problem for the future. Given how they needed to snake through the main line of the plumbing, they worked about as quickly as could be expected, and cleaned up after themselves. Their price came in a couple hundred dollars less than a larger competitor. These guys were great!"

Septic Tanks FAQs, answered by experts

You should never park or drive on top of a septic field. Vehicles can weigh upwards of two tons, and this weight can put a lot of pressure on the leach lines in the drain field. Too much pressure on your leach lines may cause them to warp, crack, or completely burst. This is an expensive and very avoidable problem.

There are three layers of wastewater in a septic tank: scum (solid waste that floats to the top of the wastewater), liquid (the relatively clean liquid wastewater in between the two other layers), and sludge (solid waste that falls to the bottom of the wastewater). The buildup of sludge is one of the main reasons septic tanks need to be pumped. If the tank is more than 1/3 of the way full with a combination of sludge and scum, it’s time to call a pro for pumping.

Yes, shower water goes into the septic tank. Shower water is a type of greywater, and in fact, all water used in a home with a septic system—including water from sinks, toilets, the dishwasher, and the washing machine—drains into the tank. When shower water enters the tank, debris like soap and hair travels with it. The solid debris sinks to the bottom to become sludge, while soap residue joins the scum layer at the top. The remaining water is treated in the tank before moving to the drain field for further treatment and dispersal. It is important to avoid putting oil or harsh chemicals down any drain, as they can cause clogs or disrupt the beneficial bacteria required for proper wastewater management in the septic system.

Schedule annual inspections, monitor water pressure, and address minor issues promptly to avoid major repairs.

Drain fields often include three to five trenches that are 18 to 24 inches deep. The pipes connecting the drain field to the septic tank will be placed between 12 and 18 inches deep, and the field as a whole will be about 100 feet long.
