Irrigation is one answer, of course, but water is becoming more expensive and, in some countries, it is just not available.
A second answer is to make sure that you use a soil that is high enough in fines (clay and silt particles) that it retains sufficient moisture to keep the grass alive and healthy. Unfortunately, sold high in fines don't drain well. Additionally, some grass varieties can form a thick thatch on the surface of the soil that further prevents water from penetrating the soil. As a consequence the soil may become waterlogged even though the conventional sub-surface drains can be clear. In fact, they can sometimes be dry!
The soil on this playing field has a high proportion of fines (25-30%) and quickly becomes waterlogged after rain. Note the shallow depression containing water - this is where the conventional agricultural drain runs.
This is the same playing field in summer. The turf above the drain obviously doesn't grow as well because of the wide and deep trench filled with gravel that is required for conventional drainage. The trench required for Capiphon™ need only be 10 cm wide instead of the usual 450 mm, and can be back-filled with sandy loam or even coarse sand. The grass will grow quite happily on top.
Catering To Sensitive Areas
For very sensitive areas such as race tracks where there can be no trace of the drainage trench, very narrow (5 cm) trenching Capiphon™ system can be used to renovate sports fields and race tracks with minimal disturbance and down-time.
Capiphon drainage can be combined with a number of other elements, including carefully constructed engineered soils, to ensure year-round performance.
Serious Alternative to Ag Pipe
Ag pipe is also called aggie, agricultural pipe, ag line etc. Capiphon also out-performs slotted pipe.
