There are a few things you'll need to know before you start: the size of your catch basin, the size of your pipe, and the depth of your hole. You'll also need to know how much water you're expecting to collect.Once you have those measurements, here's what you do: dig a hole that is twice as wide and twice as deep as your catch basin. The bottom of the hole should be sloped so that water runs towards the center. Once the hole is dug, place your catch basin in the center and surround it with rocks or bricks so that it doesn't move.

There are a few things to consider when building dry well drainage: the size of the hole, the material you'll use to line the hole, and how you'll construct the drainage system.The size of the hole will depend on how much water you need to drain. The lining of the hole is important because it helps prevent soil from entering into the well and clogging up the system. You can use a variety of materials for this, such as concrete, bricks, or stones. Finally, you'll need to create a system that will transport water from the well to a designated area where it can be drained away. This could involve installing piping or using a pump to move water out of the well.
