USGA Putting Green Construction Recommendations - Drainage

Subsurface drainage systems quickly remove excess water from putting greens. Place main drain pipes along the lines of maximum fall. Extend lateral drain pipes, spaced not more than 15 feet apart, to the putting green perimeter. All drain pipes should have a minimum continuous slope of 0.5 percent. Install perimeter drains immediately adjacent the cavity wall in low-lying areas.
