"I cannot put into words how thankful I am to have hired Delfino (Robert & Ariana) to level a section of my yard and add a gravel pad for a shed being built. They are super responsive, friendly, and more than fair. Saying I have a complicated yard is an understatement. I’ve had ridiculous quotes in the past and some who have told me what I needed was impossible. Delfino proved them wrong….and for much less money! They even surprised me with doing some work on my (also impossible) driveway at no extra cost because they had enough extra in materials. If you’re looking for kindness, fairness, and honesty..do yourself a favor and hire this incredible family business. You’ll be so thankful you did!! Thank you so much Robert & Ariana Delfino ❤️"

"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."

From a very young age, John Lemme grew up next door to his grandfather's well business. He began working for the family business in 1987 and continually learned from his grandfather. He decided after 30 years in the family business, to open his own well and water service company, J Lemme Well and Water Systems. He is by far, the most sought after well/water diagnosis expert, in Rhode Island. We offer well water pump and tank install, filtration systems, well drilling and so much more. No water? 24/7 service phone, please call 401-385-3330.

"After 2 1/2 years of not being able to secure a contractor willing to excavate or property we found Joe who told us, "No problem when do you want to start?" After receiving Joes quote we asked if he could build us a wall also. Joe stuck with us even after we were satisfied with the excavation. He encouraged to order gravel late on a Friday to finish up the site."

"Very pleased. Carlos was very respectful. He did not rush us while we prepared the grave. I would recommend him to all my friends. I posted this in on my Facebook and his as well. Our pony was 32 years old so she had been in our family since my kids were little so this was such a sad day. Carlos showed so much care and kindness."

Septic Tanks questions, answered by experts

Watch for slow drainage, pooling water in the yard, or unpleasant odors inside or outside. Addressing these issues timely avoids significant disruptions or costs.

Although cesspits may be necessary depending on your main sewage system access or nearby soil quality, they carry a few drawbacks. Cesspools require regular emptying and have relatively high maintenance and pumping costs. Certain areas also disallow the use of cesspools and may require you to cover the cost of existing cesspools to be converted into septic tanks.

Leach lines are commonly made of PVC pipe, and they’re placed into trenches filled with gravel and sand, which help treat the wastewater. The PVC pipes are perforated, or drilled with small holes, so the wastewater can drain out of the pipes and into the surrounding material, which eventually leads to the aquifer.

The best bacteria to add to a septic tank is anaerobic bacteria, which doesn't use oxygen to break down solid waste. Because there is less oxygen in a septic tank, anaerobic bacteria can decompose sludge in a sealed environment. On the other hand, aerobic bacteria need oxygen and are prevalent in the leach or drain field of a septic system.

Most deep wells can be expected to last somewhere between 30 and 50 years. This assumes that the well and all of its components are properly maintained on a regular basis. During this time, it is unlikely that modern deep wells will run dry over the course of their typical lifespan. That is one of the biggest benefits of digging a deeper well.
