"I was given a very reasonable price for the pumping of my 1500 gallon septic tank, after my last septic guy increased his price by quite a bit. They were very professional and flexible with scheduling, which was fantastic. Saul came out on a Saturday, and even cleared out the foliage over my septic tank lid without charge. I will be using them again in the future for sure."

"DDC was hired to clear and grade a building site. Exceeded my expectations. Was on time and done before schedule. After building was erected the team was back to finish grade, seed and straw, and repair rock lane. Would and have recommended DDC for any earth moving job."

"Excellent response. Pipe disconnect found immediately. Just needed gluing. The technician quickly explained and stated cost would be $89.00. I was SO relieved and happy. This company (unlike last one used which Angie's List rated as #1) included dispatch fee in price since repair was done during 1st visit. No hidden costs. No lies @ discounts."

"Bucky is the absolute best! I called a few other businesses to install my septic tank but he was by far the most professional, prompt, and genuine that I could find out there. As a bonus, he was very reasonable on price also! On a scale of 1 to 5, this man is a 10! Thanks again for the Yeoman's work!"

"Nathan was awesome to work with. I hired him to just certify my septic system on a new home that I bought, instead I had to have my whole septic moved and replaced! He did it in a timely fashion as much as he could with Inspections and rain delays. Good thing I didnt move in the house yet. I will definitely recommend Eagle and Son Septic Services."

"James provided the service on our call. He was very professional and polite. An earlier call went longer than expected and he called to let us know when we could expect him. The quality of his work was excellent. Everything looked great, works great weeks later and he cleaned up afterward. His pricing was fair and I have no complaints given the final product. I can highly recommend Skyes Plumbing if you want prompt and professional service."

Septic Tanks FAQs, answered by experts

Several things can ruin a septic tank over time, including dumping harsh chemicals (like bleach and ammonia), pesticides, and paint thinners down your drain because they can kill the bacteria in your septic tank. You should also make sure to only flush waste and toilet paper in your toilet—otherwise, you could clog your system.

You may want to increase the size of your leach field, for instance, if you add on to your home or install more bathrooms in your house. You can make your leach field larger by installing more pipes or expanding the area of the field itself. Improving the soil quality in the drain field can also make it more effective without increasing the area.

The main difference between a mound septic system and a conventional one is that the drain field in a mound system is built up into a mound composed of sand and gravel to increase the filtration time the wastewater sees before it is returned to the aquifer. There’s also a significant cost difference, with mound systems typically costing far more than standard septic systems.

Drilled wells have a pipe sticking up that’s covered in a plastic or metal casing. On the other hand, a dug well will look like a big hole in the ground and is more similar to what you’d see in a fantasy or Western movie. If you want to be sure, contact the city for documentation on your property’s construction and excavation history. 

Septic tanks aren’t bad for the environment as long as they receive proper maintenance and attention. This means staying up-to-date with professional septic system inspections and septic tank pumping. Without regular maintenance, parts of the septic system could break or stop working, potentially letting harmful waste into the soil and groundwater.
