The answer to 'how to install drainage system' is to create a well-designed drainage system to effectively manage water runoff and prevent flooding or pooling around your home. This typically involves digging trenches, installing drainage pipes, and connecting them to a suitable outlet like a storm sewer or dry well.
Start by assessing the problem areas around your property where water tends to accumulate. Mark the locations and plan the layout of your drainage system accordingly. Dig trenches at a slight slope leading to the outlet, install perforated drainage pipes, and cover them with gravel or crushed stone. Make sure the outlet is positioned away from your home's foundation. Finally, connect the pipes to the main drainage system and test the flow.
