"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."

Septic Tanks FAQs, answered by experts

Several warning signs can indicate current or future issues with your well pressure tank. If you notice inconsistent water pressure, water spitting from your faucets, clicking sounds, or electricity bill spikes without other obvious causes, it may be time to get your pressure tank and well system looked at by a professional.

Septic tanks come in multiple shapes, sizes, and materials. However, they’re often round or rectangular in shape and made from concrete, fiberglass, or plastic. There’s a range of septic tank sizes, with the average model measuring 30 to 40 square feet and holding 1,000 to 1,500 gallons of waste.

Both materials are suitable for septic tanks, but concrete usually lasts longer than plastic. If you’re buying a new tank, the prices are similar for plastic ($500 to $2,500) and concrete ($700 to $2,000). However, there’s a notable difference in repair prices, with plastic tank repair costs ranging from $150 to $2,000, while concrete repairs are between $700 and $5,000.

A septic alarm can sound different depending on your system, but often, it’s a loud, repetitive beeping noise or a steady, high-pitched noise. It may also be a loud buzzing noise. To confirm the noise is your septic alarm, check your alarm box for a red light. You can also silence your alarm with a red button or switch on the box. Look for something that says “Test” or “Mute.”

A septic tank is an underground container that collects and holds wastewater until it’s sufficiently filtered and broken down. It treats wastewater by separating waste so the leftover liquid can travel into the drainfield where the soil and gravel eventually filter and purify it. This process naturally eliminates bacteria, viruses, and other contaminants.
