Q: Can you park on top of a septic field?

• <div><p>You should never park or drive on top of a septic field. Vehicles can weigh upwards of two tons, and this weight can put a lot of pressure on the leach lines in the drain field. Too much pressure on your leach lines may cause them to warp, crack, or completely burst. This is an expensive and very avoidable problem.</p></div>

Q: What is a good perc rate for a septic system?

• <div><p>Perc rates vary dramatically, and a good perc rate could be anything from 5 minutes per inch of drainage to 60 minutes per inch. The lower the number, the faster your system will drain and the more effective it will be. A 60-minute-per-inch drain rate is the highest number considered to be good, or even allowable, draining.</p></div>

Q: Are there always two lids on a septic tank?

• <div><p>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 <a href="https://www.angi.com/articles/how-long-do-septic-tanks-last.htm">septic tanks last</a> 20 to 40 years, if yours only has one lid, it may be time for a replacement. </p></div>

Septic Tanks questions, answered by experts

Ensuring you have adequate space for your engineered septic system is crucial. You’ll need to reserve approximately 900 square feet for a three-bedroom home’s system. However, the type of soil you have, soil absorption rate, the size of your home, climate, and local zoning code will impact the actual amount of space you need.

You should never park or drive on top of a septic field. Vehicles can weigh upwards of two tons, and this weight can put a lot of pressure on the leach lines in the drain field. Too much pressure on your leach lines may cause them to warp, crack, or completely burst. This is an expensive and very avoidable problem.

Perc rates vary dramatically, and a good perc rate could be anything from 5 minutes per inch of drainage to 60 minutes per inch. The lower the number, the faster your system will drain and the more effective it will be. A 60-minute-per-inch drain rate is the highest number considered to be good, or even allowable, draining.

When considering the price of drilling a well, factor in how much you’ll save in water costs per year. The average family of four uses 100 gallons of water per person per day in the U.S. With a private water well, you can save hundreds each year.

Wells are also environmentally friendly. You don’t need to worry about drinking water treated with chemicals. Talk to at least three well pump contractors in your area. They’ll be able to tell you more about your options, give you different quotes, and discuss the biggest concerns.

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.
