Lack of proper drainage is the main reason for the death of many gardens. This is because standing water leads to diseased or root decayed plants, ruined turf, foul smell, insects etc and ultimately leads to the death of the plants in the garden. Installing proper drainage helps to solve this problem.
Installing drainage is a moderately challenging work that demands hard work.
- Identify the spot in the garden which is at a lower elevation than the remaining areas and through which water can drain out easily. In this low spot a dry well or storm drain or drainage ditch can be set up.
- Calculate the distance between the drainage area and the low spot and buy perforated pipes having a diameter of 4 inch made either of white PVC or black ADS. If drainage channels can be installed in a complete loop around the house then water will flow from one way or other to the drainage ditch. The channel can be driven through the edges of the pitch and then through the low spots in the garden which can be then directed to the dry well or drainage ditch.
- Excavate the layout area of drainage channels at 12 inches wide and 18 inches deep and with a slope towards the drainage ditch. Try to manage the slope at a rate of 6 inch per 100 feet and test the slope with stakes. Pound two stakes on the both ends of the drainage channel and tie a string tightly on them. Proceed the digging process and while digging measure the depth accurately by measuring it down from the string.
- Once the slope becomes accurate then line 3 inches of crushed stone or gravel in the trench and lay the perforated pipes and fasten the joints with tee or Y connectors or other appropriate fittings. Thereafter use agriculture fabric to cover the pipe which helps to prevent the clogging of the perforations. Then add 6 inches of stone on the sides and on top of the pipe and cover with soil.
- This helps to drain the excess water in the land to the drainage ditch. While making the drainage ensures that you are not disturbing your neighbour or it is not causing any adverse effect on your neighbour’s land. If there are any such problems then find out whether there is any storm sewer near your place and if so get permission from the local authority and connect the end of your drain to the storm sewer.
