"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."

"Woody, Craig, and the team were great to work with and did an excellent job replacing my septic system. They were very responsive and communicated throughout the project. They were transparent about all pricing and honest. They did a great job with the install and the finish landscaping they did was more than I could have expected. I highly recommend them, they are busy for a good reason."

"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

Septic tank lids may or may not be buried in a yard. Most lids are buried at least 4 inches deep unless you have an aerobic septic system. Aerobic septic systems need frequent cleanings, about every four months, so it’s best to leave these lids aboveground for easier access. For buried lids, homeowners can use risers that make it easier to locate and access a buried septic tank lid.

There is no standard depth for burying a septic tank; they are typically buried anywhere from 4 inches to 4 feet underground. The final depth depends on several factors, including the depth of your main sewer line, the height of the bedrock, soil type, local regulations, and the property's landscape. If you plan to grow grass or plants over the tank, a depth of at least 4 to 6 inches is recommended. Deeper tanks can be more difficult to locate, but a septic professional can help find it for you.

On average, you should call a pro to pump your cesspool once per year. If you have a larger home with a lot of family members, you may need to pump more (up to six times per year). On the flip side, if you’re talking about a cesspool for a home you don’t use much or if you’re the only occupant in a home, you won’t have to pump nearly as much.

A septic tank riser features a base ring that you need to install flush to the opening of the septic tank. After thoroughly cleaning the opening of the tank, fit the base ring over the opening and use a butyl sealant rope to create an airtight seal with the tank’s rim. Cut the riser rings to the appropriate height and stack them on the base ring. Then, install the riser lid. This task might be taken on by an experienced DIYer, but you should always call a septic tank professional if you are unsure of your skills.

Well water is often assumed to be hard because of its high mineral content. Hard water can lead to mineral build-up in your pipes and appliances. You can manage hard water by installing a whole-house filter system. These systems can help extend the life of your water-reliant appliances like your hot water tank and dishwasher.
