Unless you’re looking for an excuse to see your plumber more often, you’re going to need a drainage system. The purpose of a drainage system is to displace water away from your home or building to a safer place where it won’t do any damage. The rainier it is in your area, the more important it is to have a quality drainage system in place. Proper systems will make sure you never have standing water around your house. Puddles and pools of water near your foundation can change the composition of the soil, and they can attract bugs and other pests. They’ll even ruin your landscape design by drowning your garden.
