"Bill was great from the get go, he came right over and gave us solid professional advice on what we would need to do and how to go about it. Once it was determined that we would need to replace the septic tank which was an old metal tank that not only had not been used for more than 25 years, it was on the verge of completely failing. Bill took care of everything with the county board of health and the township who required a larger tank than the county. Our install turned to be a lot more work than he originally bargained for. He did not anticipate the amount of buried rock (large- boulders) in the area needed to enlarge a hole for the new 1500 gallon tank. He ultimately hauled out 5 loads of rock (boulders) and had to bring in several loads of crushed cement for fill to replace the boulders and to fill in and around the new tank, level up under and around the new lateral line to seepage pit. Bill was a total professional from start to finish, even with the set back caused by all of the stone, he was able to get right into the project and get the installation completed, since it did not require any new engineering or an expanded field he was able to get the inspection done right away which allowed us to keep the house on the market, and hopefully a new owner will be able to utilize the new system and enjoy the home for many years to come. I would highly recommend William (Bill) Farley Septic Services to anyone looking for a professional septic contractor any day of the week..."

"Scott and his sons were able to completely replace my failed septic in time for the sale of my house. It was an enormous amount of work in a very tiny space and I'm still amazed it was done so quickly. Scott updated us daily with where we were at with the process and kept on top of everything. I highly recommend Sunrise Environmental."

Septic Tanks FAQs, answered by experts

A well pressure tank is located between the well and the well pump, and it stores your water under pressure so that the well pump can eventually do its job. The well pump is activated whenever you turn a faucet on—it pulls the water from the tank into your home. Both are vital parts of a complete well water system.

While a traditional septic tank requires a leach field for wastewater disposal, it is possible to have a septic system without one. Some alternative systems, which are often used when there isn't enough space for a full-size leach field, include mound systems or sand filtration systems. In a conventional setup, the leach field is essential because it's where the wastewater goes after leaving the tank.

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.

Call a dedicated well and pump professional to install your new well pump. In some cases, plumbers may have the experience needed for the installation, but it’s always better to go with a specialized pro. Well and pump contractors have hundreds of hours of experience with all different types of wells and pumps. 

Septic tanks can clog if they aren’t pumped every few years since solid waste accumulates inside of them. Your tank might also clog if you have a habit of flushing anything other than human waste or toilet paper. Items like diapers, baby wipes, paper towels, cat litter, and personal hygiene products should never go down your pipes.
