Irrigation and drainage preparation involves assessing the property and creating a system to provide plants with the right amount of water while preventing excess runoff and erosion. Benefits of preparing an irrigation and drainage system include: water conservation, reduced costs, increased plant health, and reduced risk of flooding. Without proper irrigation and drainage, a landscape can become waterlogged, which can lead to plant death and increased maintenance costs.

Another benefit of preparing irrigation and drainage is that it can improve the aesthetics of the landscape. It can help to prevent waterlogging, which can cause unsightly mud and puddles. It can also help to direct water to certain areas, creating ponds, streams, or other water features. Proper drainage can also reduce the risk of mosquito breeding grounds, which can be a problem in some areas.
