"Lonnie and his crew were wonderful to work with and extremely helpful. I needed to get my tiny house situated and get it hooked into another septic system from the main house on the property. We also needed to get hooked into the water of the main house. He worked well with me and the septic design engineer. Most importantly he explained everything to me as I had no idea of the process we needed to follow. He was always pleasant to deal with and flexible. He had to dig up big portions of the yard to do this and he came back to spread grass seed on all the areas that were bare dirt from the project. It blended in so well that nobody can tell the yard had been so torn up two months ago! His quote was very reasonable, and he stuck to it despite having to do a few extra things that were not in the original plan. I HIGHLY RECOMMEND Lonnie and his workers. He has integrity, is a hard worker, and does a great job."

"The process was quick and easy. I just provided a water sample. It was determined that I had high levels of chlorine in our drinking water.

"I had a GREAT experience with Corey (who did the actual work) as well as everybody who worked to schedule his visit. I appreciated being given the option to hold off 'til Monday and avoid a weekend upcharge. Service was exactly as quoted and is just the going rate. They stayed in contact through the whole process. I also learned a thing or two from Corey (avoid antimicrobial soaps) and have re-committed to minimizing garbage-disposal usage. I pre-cleaned the mess in my basement and Corey left it just as he found it."

Septic Tanks questions, answered by experts

For homes with a septic tank, harsh chemicals like those found in drain cleaner or bleach aren’t recommended. Some chemical drain cleaners can disrupt the balance of bacteria in the septic tank or damage your pipes. For homes with a septic tank, you can choose drain cleaners specifically formulated for use with septic tanks or go with a drain snake. When in doubt, make sure you know who to call for a clogged drain. 

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.

The disadvantages of having a well include more maintenance, like annual testing and inspections, and high up-front costs to drill a well. Well water is also vulnerable to contamination, which is why keeping up with testing is important if you own a well. When it comes to well water versus city water, well water does offer more independence and is a reliable water source.

The best way to keep a septic tank clean is to hire a local septic tank cleaner to inspect and pump the septic tank every three to five years. Be sure to only flush human waste and toilet paper down the toilet, and don’t pour grease, oil, fats, coffee grounds, or food scraps into your drains.

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.
