Water by-passing drain fixed by a 1" trench intercept drain
Bathgate Golf Club
Issue: A drainline is in situ just off the green, however during periods of heavy rain, surface water was running down a slope onto the green, by-passing the drain. This wetness was causing the turf on the green to deteriorate.
Solution: The FR1 trencher was used to dig a shallow 1” wide trench to form an intercept drain and link the surface to the drain below, allowing the surface run-off to effectively fall into the slit rather than onto the playing surface. This process yielded positive results from a trial carried out by ForthRoots with the STRI, notably a significant increase in surface firmness. This process will require to be repeated over the winter to prevent the trench closing over but in the spring time when the weather becomes drier, the greenkeeper can to allow it to heal.
Results: The head greenkeeper, Robert Burns, appreciates the importance of limiting the total amount of water an area is exposed to and believes this process to be a quick and efficient way of limiting the volume of water hitting the green, by minimising surface run off.
Dr. Christian Spring (STRI) says:
"On all assessment dates, plots where 1” sand slits were installed, irrespective of whether a sump box was fitted or the turf Gradened, had significantly lower soil water contents, in comparison to the untreated turf."

A Problem We've Solved
Existing drainage failing due to slow water movement caused by the distance from problem area to main drain.
Solution: Use ForthRoots FR1 4" blade to install drainage pipe or capillary flow drainage materials, providing secondary drainage which can be linked to main drains.
