Should You Pump A Dry Well

How To Install French Drain to Dry Well Discharge

You dont need to pump or empty a dry well as it will not fill up. The holes born around the well will eliminate the water into the ground over time. The gravel added to the lining helps this process, allowing the water to filter into the soil. This water will then be added to the soil as groundwater which is totally harmless.

Dig The Hole And Trench

Coming out from the downspout, at least 10 feet from the foundation , dig a hole about 4 feet deep and wide. With a long-handled shovel, tunnel under the sidewalk and dig a trench 1 foot deep and 6 inches wide that slopes gradually toward the hole. Shovel the soil onto a tarp. Save the sod to patch over the hole.

Tip #: Consider A Dry Well At The End Of Your Drain

You can end your French drain in several ways. Many people, especially those living in warmer environments, end their French drains by passing their piping above the ground somewhere downhill from their homes.

Those living in colder climates, however, prefer installing a dry wellinstead. Typically filled with gravel, a dry well is a large water reservoir thats dug beneath the frost line. This is where your French drain will drain into.

A dry well helps dissipate the water into the ground without the water ever rising above the frost line. It should be at least 20 feet away from your foundation.

How To Build A French Drain With Dry Well

A French drain is a trench filled with gravel or rock or containing a perforated pipe that redirects surface water and groundwater away from an area. A French drain can have perforated hollow pipes along the bottom to quickly vent water that seeps down through the upper gravel or rock.

French drains are primarily used to prevent ground and surface water from penetrating or damaging building foundations. Alternatively, French drains may be used to distribute water, such as a septic drain field at the outlet of a typical septic tank sewage treatment system. French drains are also used behind retaining walls to relieve ground water pressure.

How To Build A Dry Well

Most dry wells are pits filled with gravel and debris. Because they are filled pits, there isnt a lot of reserved room for water. So more often than not, the pits are quite large. But another way around this is via a chamber.

This chamber, or tank, can be buried under the ground with holes poked in it to create a porous wall. When you build a dry well like this, the water has more time and space to escape so it can handle more torrential weather.

Because the wells are buried and the land is solid above them, you can build them almost anywhere. They wont be noticed nor take up land space. Here is a great way to build your own dry well in your yard.

Add An Underground Drainage Pipe

One of the best ways to get rid of water from a low spot is to simply drain it away through an underground drainage pipe. For this to work, you need an area to discharge the water thats lower than the inlet. The underground drainage pipe should slope downhill at least 1/8 in. per foot. If you had a discharge outlet 100 ft. from the inlet, it would have to be about 1 ft. lower.

To create the drain, youll have to dig a gradually sloping trench from the source to the outlet. Then bury a plastic catch basin at the source and connect it to the discharge with PVC drainpipe. This system has a few advantages over a French drain . Since the pipe is solid, and not perforated, theres no need to provide gravel for drainage along the length of the drainpipe. Also, smooth-wall pipe drains water quickly, and if it gets clogged, you can use a drain snake to clean it out.

What Is The Purpose Of A Dry Well

Dry Well or Sump Pump, Which Works Better with French Drain – DIY

A dry well is designed to receive water from a drainage system and disperse it below ground. All drainage systems have to end somewhere. If you cant drain your water into a storm drain or dont want to direct runoff into a pond or water garden, a dry well is the perfect choice. Think of it as a method for taking runoff water and filtering it into the soil deep beneath the surface of your yard.

  • A dry well receives water from a drainage system, such as gutter downspouts, drainage ditches, or a French drain.
  • Dry wells receive runoff water from a drainage system and distribute the water underground.
  • Dry wells do not do well at collecting runoff on their owna drainage pipe or system must direct water to the dry well.
  • A dry well eliminates the need for terminating a drain aboveground, where drain water can cause flooding and erosion.

In many regions, its illegal or impractical to channel runoff water into municipal storm drains. Rather than channeling the water from your downspouts out into your yard, where they can flood your lawn, a dry well allows you to get rid of that water underground.

The Benefits Of A French Drain

If you have a wet basement or standing water in your yard, you may be wondering if a French drain is the right solution for you. But what exactly is a French drain? And how does it differ from a dry well?

A French drain is a sloped trench that is filled with gravel or other porous material. The trench directs water away from your home or other problem areas. French drains are most commonly used to prevent basement flooding or to reduce the amount of water in your yard.

Dry wells are also used to redirect water away from your home, but they work differently than French drains. Dry wells are typically deep, cylindrical pits that are filled with gravel or other permeable material. Water enters the dry well through holes in the sides or bottom of the structure and then seeps into the ground, where it is naturally filtered and absorbed.

Both French drains and dry wells can be effective solutions for redirecting water away from your home, but there are some key differences between the two:

  • French drains are sloped, while dry wells are typically deep pits.
  • French drains rely on gravity to pull water through the system, while dry wells allow water to enter through holes in the side or bottom of the structure.
  • French drains use gravel or porous material to filter water, while dry wells rely on natural filtration through the ground.

  • Filter out the leaves and sediment before the water reaches the dry well by placing gutter guards or screens on the roof downspouts.
  • Try to avoid debris of trees from falling in the flow paths.
  • Repair any damages in the gutters or downspouts.

    Tip #: Place French Drain Below The Frost Line

    A properly installed French drain will begin at the depth of the base of the perimeter beam and is installed with a 1% minimum slope . This is usually below the frost line.

    Generally, those placed below the frost line tend to provide year-round performance, especially in cold regions. They work in all seasons and usually dont suffer from issues such as frozen obstructions caused by the freeze-thaw cycle.

    Insulate Above The Frost Line

    While the majority of your French drains piping system will be buried below the frost line, any of the vertical maintenance spouts and parts of the final drainage system may include some piping thats left above the frost line.

    What Are The Risks

    One common risk when dealing with a dry well is when the rainfall becomes too heavy for the dry well to handle. This water displacement system can become easily overwhelmed by storms and heavy rainfall and clogged due to branches and debris entering the dry well system. To prevent this, you can have your dry well cleaned regularly and cleared from debris. When a problem this severe happens, it can treat the flooding of your entire property, causing additional damage and repair costs.

    Dry wells have been known as an effective way to drain stormwater by transferring it to underground water, although some risks can appear when the rainfall is contaminated. Dry wells are an excellent way to recharge the local groundwater supplies. Still, the groundwater can quickly become contaminated when certain substances or illegal surface spills find their way into the dry well. You can monitor this by correctly installing a dry well and using appropriate pretreatment.

    • The stormwater runoff can contaminate the underground water

    A dry well does not need to be pumped or emptied. Its not a solid tank that fills up and requires emptying. Remember, the simplest dry wells are just a hole in the ground filled with large gravel. This gravel material helps the hole retain its shape and allows the water to filter down into the dry well, where it will then leach into the surrounding soil as groundwater.

    Dry Well Vs French Drain: What Are The Major Differences

    Proper drainage can protect your yard and home from soil erosion and eventually foundation damage. There are several ways to steer rainwater away from your home, but dry wells and French drains are the most popular. So, what is the difference between a dry well and a French drain?

    Dry wells collect rainwater in your yard, but they only work well if you have good soil drainage. French drains direct water towards a trench at the lowest point of your yard via a perforated pipe. They both prevent soil erosion, but French drains are more effective and they can increase home value.

    Its important to have good drainage in your yard because it can save you thousands of dollars in foundation and basement repairs. Sump pumps are an effective alternative to dry wells and French drains, but they can be expensive because they require electricity. Follow along as we compare dry wells and French drains so you can decide whats best for your home.

    Install A Dry Well At The End Of Your Cold

    While most French drains run downhill behind a home, this may not work as well in areas prone to freezing. If youre planning on installing a French drain in your South Hills home, consider installing a dry well at the end of your drainage system. A dry well is a large hole placed below the frost line where water can collect and have enough time to dissipate into the ground before freezing.

    For additional security, you can install a perforated metal drum inside the dry well to not only help the water seep into the earth, but to prevent any dirt clogging the dry well.

    Why Do Dry Wells Fail

    Dry wells are reliable but they can fail due to debris and clogs. They are vulnerable to clogs because they are always exposed to the elements and everything in your yard. This includes dirt, grass, dust, rocks, and pebbles.

    You can stop your dry well from failing if you keep a close eye on it so that it doesnt get clogged. The only way to be sure that your dry well is clogged is to pump it. Pump the water out and examine the dry well to see what is causing the clog.

    This sounds like a lot of work, but its much better than having to excavate it when its too late. You must excavate your dry well if its completely clogged, so its ideal to observe it when you notice problems.

    It is important to be responsible for the runoff water collected from your drainage system. A dry well is a great finishing touch for a French drain as it drains the drain underground where it cannot cause flooding or provide a breeding ground for insects.

    To use these methods yourself, follow these steps:

  • Dig a drainage ditch at a slope of 2 inches per 10 feet. Install a french drain in the drainage ditch using garden fabric, gravel, and a perforated pipe.
  • Where the drainage ditch ends, dig a dry well. A dry well may be a hole 4 feet in diameter and 4 feet deep.
  • Fill the hole with garden gravel or install this dry fountain tank and surround it with landscape gravel.
  • Point the end of the drain hose toward the center of the drying pit. Cover the drying pit with grass.
