"I hired Bill Farley to construct a new septic seepage field and upgrade my current septic tank. The job also required cutting down and removing a forest from the site and demolishing and removing a large storage shed. He was knowledgable, competent, honest and did a good job in spite of complications. Thinking about it afterward, it was not only having the job done right, but having someone you could trust and knowing that he job would be done right and not having to worry or check up. My only critisism would be that he is not up-to-date with electronic communication. But then neither am I."

Customers say: Quality work

"We hired Michael Lacken to replace our aging septic. From the first meeting it was very clear they are absolutely a cut above standard contractors. We have a difficult lot which is both small and shallow, which required a very specific type of system to meet township and state regulations, and Michael's team were able to deliver. The whole process has been smooth from start to finish; communication with their team is excellent, the septic has been installed with no hidden fees or costs to us, and they have been very thorough in making sure we are happy with the results. I would recommend this company 100% ."

Septic Tanks FAQs, answered by experts

If there’s a problem with your sewage system, you might notice water pooling on the ground around the tank, which could indicate an overflow. Clogged and sluggish drains or foul smells coming from your plumbing are also signs that there might be a blockage in your septic system.

The average cost to replace a septic tank or install a new system is typically around $7,350, with a broader average range of $5,000 to $12,000. However, total project costs can vary widely, from $5,000 to as much as $22,500. Key factors influencing the price include the size and type of the septic system, the tank material, and the size of your house.

It's important to distinguish between the cost of the tank itself and the cost of the entire system installation, which is significantly more. For the tank alone, costs vary by size:

  • A tank for a one-bedroom house typically costs $500 to $900.

  • A 1,000-gallon tank, suitable for most one- to three-bedroom homes, costs between $900 and $1,500.

  • A tank for a five- or six-bedroom home generally costs $1,200 to $1,600.

With regular testing, treatment, and maintenance, water from a community well should be safe to drink. Unfortunately, the EPA does not regulate private wells, and contamination can happen. 

If you have doubts about the quality and safety of your drinking water, you have options for testing. You can pick up kits from your local home supply store or harvest samples and send them to a local testing facility. To get the most complete water quality testing and system diagnosis, seek a local well professional. They know what to test for and can recommend and implement a longer-lasting solution.

Modern septic tanks have two lids: one that covers the inlet where wastewater flows into the tank and one that covers the outlet where the treated water flows out to the drain field. However, older septic tanks installed before 1975 may have only one lid. Because septic tanks last 20 to 40 years, if yours only has one lid, it may be time for a replacement.

Depending on local conditions, a deep well may be a better choice than a shallow well. Deeper well depth accesses groundwater that has been naturally filtered through many layers of soil and rock. This reduces surface contaminants and may offer cleaner water, but deep wells cost more money to build and maintain. The water may be harder and have higher radioactivity, too.
