"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

Septic systems typically require servicing every 3-5 years, but frequency varies according to household size and tank capacity.

Your septic tank naturally contains the good bacteria it needs, so you typically don't have to add more as the system produces them on its own. However, if you wish to replenish the bacteria, you can use natural methods. For example, you can add three rotten tomatoes to your garbage disposal or flush 1/4 ounce of active yeast down the toilet every three months. While store-bought septic enzymes and chemicals are available, many additives are unnecessary and may even harm your system. The most effective way to maintain a healthy bacterial balance is to avoid using chemical drain cleaners, which can kill the beneficial bacteria in your tank.

Septic tanks and cesspits are both types of sewage and wastewater systems, but they differ in key ways. The main difference between the two systems is that septic tanks separate sewage from wastewater and allow the latter to flow into a drainage field to filter and disperse into the soil. Cesspits don’t have outlets and instead, store sewage until it needs to be pumped by a professional.

You only need to pump the septic tank. The leach field allows the liquid and waste to naturally seep into the ground, so there’s no need to pump the leach field. You should call a local septic tank pumping service to remove the materials from the tank every three to five years. Without pumping the septic tank occasionally, solids could flow into the leach field pipes and clog them.

Yes, shower water goes into the septic tank. Shower water is a type of greywater, and in fact, all water used in a home with a septic system—including water from sinks, toilets, the dishwasher, and the washing machine—drains into the tank. When shower water enters the tank, debris like soap and hair travels with it. The solid debris sinks to the bottom to become sludge, while soap residue joins the scum layer at the top. The remaining water is treated in the tank before moving to the drain field for further treatment and dispersal. It is important to avoid putting oil or harsh chemicals down any drain, as they can cause clogs or disrupt the beneficial bacteria required for proper wastewater management in the septic system.
