Pumps and Well Service Water Treatment and in-depth trouble shooting. Often Beyond Pumps can solve problems other companies cannot. Beyond Pumps also has emergency generator services. Our team has licensed electricians, a civil engineer, water treatment operators, and years of experience in well work.

"We were having a lot of air in our well system. Causing the water to spit and sputter when we turned on the tap inside. They came out quickly and fixed the problem. It’s been a couple weeks now and it’s been so nice not having to go manually purge the air from our tank! Kind and courteous and highly recommend them. We are having them come back to install a water treatment light into our system next."

Excavating questions, answered by experts

Trenches are 12 to 24 inches deep and 8 inches wide. However, the right depth for your trench will depend on the nature of your project. For example, if you’re digging a trench as part of a French drain installation, it should be 18 inches deep. An excavation professional can explain how deep your trench should be.

Septic tanks are typically buried between four inches and four feet deep, depending on the property, the soil, and the size of the tank. When the septic tank is buried on the deeper end of this range, it may be harder for you to locate it on your own with a soil probe or just by observing the yard for signs of the tank. However, if you have trouble finding the septic tank, a pro will be happy to help you.

Most residential basements are 8 to 10 feet deep. You can dig deeper depending on building codes, but it does become more difficult. You’ll likely need to install stronger foundation walls and additional supports to handle the increased load. Depending on the water table, you may also need a water management system. Clay soil can support a deeper foundation than sandy soil. A structural engineer will be able to tell you the maximum, feasible depth.

Digging out a basement takes anywhere from a few days to a few months. Most projects take at least two to five weeks, but it could take several months if you encounter obstacles. This project takes longer if you need to brace or raise your home before the excavation. Digging out a basement in new construction can take as little as three days.

Yes, professional installations include trenching or borehole drilling required for ground loops.
