DIY In-Ground Drainage System

A good in-ground drainage system allows you to ensure that your home is drained and your soggy backyard remains dry at all times. You can put an end to all the water issues in your home by having a good in-ground drainage system. You do not even need to spend excessively by hiring an expert because, with the right knowledge, this is what you can do for yourself. 

This will be a long-lasting and permanent solution for your flooded yard. This is a step-by-step guide on how you can go about the installation. It takes a lot of digging to get this done properly but once you get it done perfectly, your drainage problems are over. 

Materials Needed

  • Ample supply of crushed rock
  • Y-fittings
  • Drain tubing
  • Stakes
  • Drain cover
  • Landscape fabric
  • Dry well
  • Fabric sock

Tools Needed

The following are needed for your DIY in-ground drainage project: 

  • Garden rake
  • Line level
  • Chisel point bar
  • Level
  • Hammer
  • Cordless drill
  • Utility knife
  • Spade
  • Wheelbarrow
  • Tape measure

Basic Steps

  • Dig a trench: Commence by digging a deep trench that will house the drain tile.
  • Installation of dry well: The water is going to be drained into the dry well.
  • Tube connection: The tube directs water to the dry well and if you are one of the homeowners battling one water problem or the other in their backyards, you will have to either dispose of your property or you get to face the issue and tackle it. A good number of wet yards can be drained without issues and it is very rare for you to have water problems that cannot be handled. But in most instances, it is not something that you cannot sort on your own. 

Knowing the Origin of the Problem

In a lot of cases, it can be quite easy to locate where the water is oozing from. It can be a slope close to your building, a depression on your property which leads to pooling of water, or too much roof water draining close to the foundation. You are also able to handle little foundation drainage problems by ensuring that the soil is sloping away from the home building. 

Gutters that have also been installed correctly, fitted with a good downspout that empties away from the foundation, are excellent choices. 

Reach Out Before Digging

Just like with any other yard project that needs digging, you must locate the areas where television cables, telephone, and electrical lines alongside gas pipes are located. You should call the local utilities to get the needed details. 

The location of the gas pipes and the underground cables can determine the way you are going to route your drains. You may also want to think of a different route or do a temporary disconnection of the utility until you can finish the job. 

Step-By-Step Process

  1. Commence Digging: You have to dig a very big hole and one that has the depth that can take both your dry well and the overflow tube. Scoop out virtually all the dirt but let there be some amount so that you will use in the refilling of the hole. 
  2. Do Digging of a Connecting Trench: You should dig the trench to such a depth that it will be able to drain in a downhill direction from the section of the dry well. You will also make use of a minimum of three inches of the crushed rock to include the lower portion of the trench so water can be absorbed. 
  3. Installation of the Dry Well: You commence the installation with the preparation of the dry well by removing the drainage ports in the sections of the dry well. Do a scoring within the proximity of the knockout hole using a utility knife and then you strike using a hammer. 
  4. Get the Dry Well Fixed: Do assembling of the dry well after the perforations have been done on the sides. Follow this with screwing of the upper portion of the dry well to the lateral walls using two-inch stainless steel screws. 
  5. Fix the Dry Well in Place: Put the dry well inside the hole once you are done wrapping the sides using landscape fabric. To fix the fabric beneath the dry well top cover, do loosening of the screws, push about 2.5 centimeters of fabric beneath the cover then do a retightening of the screws. A four-inch drain tube with perforations is linked to the side of the dry well as it will assist in draining off and percolation of the overflow water. 
  6. Connection of the Drain Tube: Use the line level to do a measurement of the trench depth. The farther you are from the well, the more the depth that will be needed. Do an adjustment of the gravel in the lower portion of the trench as need be. 
  7. Enclose the Tube Using Fabric: Enclose the tubes using fabric sock but let there be about five centimeters at the ends for an overlap with the other section of the tubing. The fabric is going to remove all the soil particles and this will stop the tube from becoming clogged with sludge. 
  8. Ensure the Tube Slopes for Water Drainage: Recheck the drainage to ensure that there is the proper sloping for the tubing. Modify the base of gravel as needed. Do overlapping of the sock ends after you do the connection. 
  9. Do Connection of Downspouts and Drain Line: Link the downspout tube with the principal drain line. Make use of a Y-fitting to do the connection. Place the sock on the connection. Immediately the tubing is fixed, enclose it with a minimum of three inches of gravel. Use landscape fabric to enclose the gravel and let the topsoil cover the trench. 
  10. Fix a Cover at the Tube End: Fix a drain cover towards the tube end so that it can keep the insects out. There should be a rock bed to stop erosion. A Y-fitting should be done in the area where the tubing traverses the gutter downspout. Drainage of the roof water from the gutter should be straight into the principal drainage line. After all the installation of the drainage system has been done, use many inches of rock to enclose the tube.
