Drip Tip:  Dripline Layout for Slopes 

In this Drip Tip, we will cover design tips when using XF Dripline on slopes. An increasing number of municipalities are restricting the use of sprays or overhead irrigation on slopes. Dripline can be successfully used in these areas to eliminate erosion and runoff.

XFD On-Surface or XFS Subsurface Dripline 
Use these tips when using XFD On-Surface or XFS Subsurface Dripline to ensure the landscape is receiving enough water at the highest point and not too much at the lowest point.

• The design of the dripline system should account for slopes on the site since runoff may occur at low points.
• Slopes less than 3% do not require special design considerations.
• Slopes greater than 3% should increase the dripline spacing by 25% in the bottom 1/3 of the zone.
• Dripline should run perpendicular (across) the slope when possible.
• With steep sloping landscapes, water movement within the soil can be significant.
• The area at the bottom 1/3 of the slope should be controlled as a separate zone.
• Dripline lateral should run perpendicular (across) the slope whenever possible.

You can find answers to many of your dripline questions, including helpful formulas, application rates, and calculation examples, in the XF Series Dripline - Design, Installation and Maintenance Guide.
