"We recently had this company replace our original 1000 gallon septic tank with a 1500 gallon upgrade, along with an additional drain field line and they did a great job. If you want people who are skilled, hardworking and honest to handle your project, then I recommend that you give NC Septic & Pump your consideration. Their communication is excellent and they are very easy and pleasant to work with."

"He over charged me. I paid 1500.00 for my septic tank to be cleaned out and rejuvenated it, as he called it. He quoted over the phone 400.00, so I expected to pay 600.00. When he got here he started to tell me about an easier way to find my septic tank for next time. He was going to add risers for me. He said the price of that was 2800.00 I was like I ca not afford that, so maybe another time. He told me he would charge me 1500,00 to do the whole job. He said he would give me a first responders discount, I told him I work in the Emergency Department at a hospital, plus I was still in my uniform when I met him, I had just gotten off of work. He said that he counts that as a first responder. Then, he said he would give me a first time customers discount and the total went from 2800.00 to 1500.00 but I had a water line directly over the tank and he could not do the risers, but he still charged me 1500.00. I felt like I was ripped off! It had to be cleaned out and I just wanted to get it done so that I could shower and go to sleep. He came out on a Monday morning a little after 9am. It was not a holiday or weekend. He did not do any extra work that would have cost 1500.00. I was confused and just paid him. Even though I felt like he was ripping me off. He did clean out all the materials inside of my septic tank. He was friendly and explained how the septic tank worked. I still feel like I triple paid for a job."

Septic Tanks FAQs, answered by experts

The size of your septic tank plays a role in determining the proper size of the drain or leach field. As a general rule, you should have 1 square foot of drain field size per gallon of septic tank capacity. However, you could install a leach field that’s as much as 2.5 square feet per gallon of septic tank capacity. Most professionals determine the right septic tank size and drain field size by the number of bedrooms in the house. A three-bedroom house needs a minimum 1,000-gallon septic tank, for example.

Most professionals recommend that a deep well pump shouldn’t run more than 10 hours consecutively before cycling off. Overworking the well pump beyond the recommended amount can prematurely wear out your pump and burn out the motor, which means replacing it more often than you otherwise should need to. Your well pump should also come with the manufacturer’s use and maintenance recommendations that are specific to the model.

Permits command adherence to health and environmental standards, with submission crucial for new system installations or extensive modifications.

Depending on local conditions, a deep well may be a better choice than a shallow well. Deeper well depth accesses groundwater that has been naturally filtered through many layers of soil and rock. This reduces surface contaminants and may offer cleaner water, but deep wells cost more money to build and maintain. The water may be harder and have higher radioactivity, too. 

The ideal depth of a septic drain field is 18 to 36 inches below the surface. The trenches must be deep enough to allow proper wastewater distribution and filtration while remaining shallow enough for oxygen to reach the soil, promoting bacterial activity that helps break down contaminants. In areas with high groundwater or poor drainage, shallower systems like mound drain fields may be required.
