Flood can result for a lot of reasons on your site, but one of the ways to prevent it is by constructing or installing drainage.
Neglecting drainage can erode the beauty of your landscape, it could lead to flooding of basements, destruction of plants ,walls and can even cause health
It is important to do your drainage before heavy rain, construct it in such a that it can be able to take water from wrong places and uses gravity to drain
it away either to the public drains or along the slope to the outside.
One way is to channel water directly from your roof with a pipe straight to the drainage which in turns directs it out in a rivulets of water.
Another drainage system is called the “dry well” by this big pits dug and filled with stones but with no drains allows the water to slowly percolates into
surrounding soil and in no time the place becomes perfectly dry.
Also permeable pavings with lines of spaces all over the pavement done in a decorative fashion can also allow water to easily drain into the surrounding soil.
From “ehow” you can also follow these instructions when you are installing your garden drains with pipes-
Installing a drainage system in your yard is a great way to fix your lawn drainage issues. You will need to have a proper drainage system to help the lawn
look better. It will aid in relieving waterlogged areas around your yard or farm field.
Things You’ll Need:
Large rocks or broken pieces of brick
Long drainage pipes
Slit drainage pipes
Step1 Create a soakaway which will accumulate water from drainage pipes. This should be situated at the lowest area of your field or garden. The soakaway must
be 3 square feet and 4- to 6-feet deep. Fill the first 2 feet of the soakaway with things like large rocks or broken pieces of brick. Then have 1/2 foot of
small rocks. Cover the last 6 inches with a layer of soil until it is level with the rest of the ground.
Step2 Use flexible and lightweight plastic drainage pipes for the drainage system. Use sand to make a small line along the area you are thinking of laying the
pipe. Dig up some turf that is 5-inches wide and 15-inches deep along the primary drainage line. It should be going at a decline from top to bottom.
Step3 Make sure the trench is working correctly by putting some water in the hole. If the water goes all the way to the bottom of the hole without stopping,
then the trench has been dug correctly. Put a layer of stones about 1-inch deep on the bottom of the trench, and put the drainage pipe on top of the stones.
Step4 Keep laying stones in the hole so it surrounds the sides and top of the drainage pipe until the trench is 4-inches deep. Cover it with the soil that was
dug out of the trench until it is level with the layer of turf.
Step5 Dig slit drainage passages for the slit drainage pipes. These passages will be 4 inches shallower than the main passage, and it will stop above the
primary drainage pipe. This will allow the water to go out of the side passage and run off into the primary drain passage and into the primary drainage pipe
and into the soakaway.
Step6 Lay the slit pipes on sand and fill in the area around the sides of the pipe. Cover the area with turf and soil.
