"We couldn't be happier with the work they did for us! He completed our septic system, leach field, and slab preparation, but went above and beyond what we expected. Our property was very rough, full of rocks, stumps, brush, and bushes. He took the time to remove stumps and rocks, used the excavator (very skilled) to smooth out the entire property, built a beautiful rock wall using rocks dug from the property, and seeded and hayed the area. The transformation is incredible! Everything looks so nice, and we couldn't be more pleased with how our property turned out. It's not often you find someone who takes so much pride in their work and goes the extra mile to make sure everything looks great. We highly recommend him and would absolutely hire him again."

"great, Derick was very communicative, kept me informed all through the project and gave me cost estimates as the project grew in scope. I needed semi-emergency work on my septic system and responded right away and fixed the problem."

"The gas company came in to replace a meter.  They found that the vinyl siding company we used in the past had cut and covered the safety valve.  The one night that it's super cold out, the gas company had to shut off our gas (heat)!! I called Richard at 9:00pm.  He got back to me first thing in the morning and had his crew take care of it by 7:30am.  They are really THE BEST!!  The gas company is here now and hopefully we'll have heat soon."

Septic Tanks FAQs, answered by experts

The best bacteria to add to a septic tank is anaerobic bacteria, which doesn't use oxygen to break down solid waste. Because there is less oxygen in a septic tank, anaerobic bacteria can decompose sludge in a sealed environment. On the other hand, aerobic bacteria need oxygen and are prevalent in the leach or drain field of a septic system.

You can add three rotten tomatoes or 1/4 ounce of yeast to your septic tank to speed up the decomposition of sludge. You can add the tomatoes by way of your garbage disposal and the yeast by way of your toilet. You can do either of these additives once every three months as needed.

Digging a well can cost between $20 and $25,000, depending on your needs. If you’re looking to dig a well yourself, all you need is a shovel. If you’re looking to have a well drilled by a professional, you can expect to pay around $15 to $30 per foot. The total cost of drilling a well will average to $5,500.

The smallest septic system available for purchase typically includes a 750-gallon tank. However, the smallest size you can legally install is determined by local regulations, and many areas require a minimum capacity of 1,000 gallons. The cost to install a small septic system generally ranges from $2,910 to $13,900. Before proceeding, it is essential to check with your local health department or consult a local septic professional to confirm the minimum legal requirements in your area.

While abandoning a tank without treating it and following strict rules is illegal, there are several other ways to dispose of an old septic tank. One standard method is to pump out and crush the tank where it rests and bury it in the soil. Another is to remove it and transport it to a landfill. Finally, if abandonment is the best option, your contractor must pump out the tank and fill it with inert material, such as sand or concrete, depending on local regulations.
