How To Install Drainage Systems

Creating a nice lawn is not just about planting Bermuda grass and watering them so they will become carpet-like. A proper drainage system must be in place before planting the greens for the lawn to look better, longer. It will also save you time, money and effort from repairing your lawn when pools of water start forming in obscure areas of your lawn, due to the absence of a drainage system. So take these tips on how to install a drainage system in your lawn:

Plan the route of your drainage system. It is best to put your ideas on paper. Plan where to lay the pipes. It is recommended to lay out the pipes in a loop so water will flow the other way if there is a problem in one area, and will not clog the pipes. Coordinate the layout of the pipes with your preferred lawn design, so if you plan to place some structures, these should not obstruct the drainage system. It is also a rule of thumb to create a soak way where water from the pipes accumulates. The soak way should be located at the lowest point in the lawn so all the water will run smoothly through the pipes and will not clog or accumulate elsewhere.

Select the right materials. There are different kinds of pipes available, and choosing the best one will depend on the kind of soil in your yard and the kind of plants that will grow around it. There are pipes that are prone to root intrusions; these are usually the flexible perforated and non perforated pipes. The preferred type is the ADS solid pipes, which will not need too much maintenance and replacement. Also choose the right sizes for the pipes and connectors, which will depend on how large the lawn is and how much volume of water will pass through.

Prepare the lawn. Dig the trenches in the lawn as planned, and once the lay out has been completely dug, test if water will flow smoothly up to the soak way. Otherwise, make the adjustments on the diggings until water flows smoothly. As a rule of thumb, there should be a 3 inch fall for every 100 feet of run, or a slope of 1/400. Dig the soak way 4 to 6 feet deep and 3 square feet wide. This will be filled with large rocks first, then with smaller rocks, and  the top most layer with soil until it is in the same level as the rest of the lawn. For the pipes, place small rocks in the trenches where the pipes will be laid.

Do the proper installation of pipes. Lay down the pipes on the trenches, making sure that the connectors are properly sealed. Test again by running some water through the pipes. If everything is working, you may now cover the pipes with turf and soil.

Place markers on your drainage system.  For maintenance purposes, it is best to know the exact location of the pipes, so place markers like bricks or odd colored rocks on the route of the pipes. This can add up as a design on your lawn.
