"Thomas was very responsive and courteous. He showed up bright and early on Monday, as promised. He reached out to coordinate with the previous pro who had identified the issue but did not have the equipment to clear the blockage. Thomas found our septic tank which had not been opened the entire 25 years we've own the house. He quickly removed the blockage and resolved our issue pumping sewage up to the septic tank from the fish house. I will certainly call him first next time we have a problem."

"I found Caldwell Septic and Drains on Angi. He got in touch with me the day I posted my inquiry, and we quickly scheduled time for him to come out. We had two lines from our bathroom clogged and Zach came out and fixed both quickly. He explained what he needed to do and was professional. He then explained the invoice to me and thanked me for my business. I’d definitely recommend Caldwell Septic and Drains and will be using them in the future."

Septic Tanks questions, answered by experts

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.

There are a variety of different types of septic systems that can work in your home—such as conventional anaerobic systems, chamber systems, drip distribution systems and mound septic systems. All of them work using natural processes to break down solid waste and effectively treat wastewater without needing to be connected to a city sewer system. Which type of septic system you need will depend on characteristics of your property like how high the bedrock is or groundwater table is. Different types of systems come at different costs to install.

A household of four can easily fill a 1,000-gallon septic tank within a week. It may be 10 to 14 days for smaller households. But the reason why you don't need weekly pumping is because the tank's contents eventually reach the overflow pipe. They flow down this pipe to the absorption area whenever water is used in your home. The tank keeps working at this full level until it's pumped again.

Talking with a septic pro before planting trees near your tank is best to ensure the roots won’t interfere with your septic system. However, there is an easy way to figure out where to plant a tree—but you’ll need to know how tall it can get when it’s fully grown. For instance, if the tree can reach 50 feet, plant it at least 50 feet from your septic system.

Conventional anaerobic septic systems are the most cost-effective and least expensive type, with installation costs typically ranging from $3,000 to $8,000. For comparison, sand filter systems cost between $7,000 and $18,000, while mound systems are the most expensive at $10,000 to $20,000. Several factors influence the final price. The tank material is a key consideration; plastic tanks are the most budget-friendly option, starting around $2,900, but concrete and fiberglass tanks offer greater durability and longer life spans at a higher cost. The size of the tank also affects the price. For example, a 1,000-gallon tank costs between $900 and $1,500, whereas a larger 1,500-gallon tank costs $1,500 to $2,500.
