"Replaced leech field- he did an excellent job removing my old leech field and replacing it with a better system. From the time I entered the job in homeadvisor (approx 8am) I was called back before noon. We scheduled a site review later that day. From the time I selected Roadway, there was constant progress. Even when the permits were in progress, they were in constant contact to let me know what was going on. When the permits were in order, they worked nonstop until the job was done. Their work was excellent, prompt and neat. Highly recommend."

Septic Tanks questions, answered by experts

The ideal depth of a septic drain field is 18 to 36 inches below the surface. The trenches must be deep enough to allow proper wastewater distribution and filtration while remaining shallow enough for oxygen to reach the soil, promoting bacterial activity that helps break down contaminants. In areas with high groundwater or poor drainage, shallower systems like mound drain fields may be required.

Most shallow residential wells are somewhere between 25 and 50 feet deep. They are among the simplest well systems. Deeper wells usually involve drilling to a much greater depth. Water wells for household use are typically 100 to 500 feet deep, depending on local groundwater conditions. Some may be up to 1,000 feet deep or more. 

The lifespan of your well casing depends mainly on the material it’s made from. Stainless steel and galvanized steel casings are designed to withstand the pressures and environment of deep-water wells but are susceptible to corrosion. Most steel casings last from 20 to 35 years, on average. PVC casing is highly durable and, if used correctly, can last up to 50 years.

Several warning signs can indicate current or future issues with your well pressure tank. If you notice inconsistent water pressure, water spitting from your faucets, clicking sounds, or electricity bill spikes without other obvious causes, it may be time to get your pressure tank and well system looked at by a professional.

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.
