How does Capiphon™ perform?

Better in all Respects

Capiphon™ begins to drain sooner and continues to drain water long after slotted pipe ceases, even draining below the level of the outlet (zero head - from left to right on the graphs).

This effect is even more pronounced when in the soil. The soil, itself, is the limiting factor in flow rate.  Because Capiphon™ uses capillary action, it is in dynamic equilibrium with the moisture in the soil. Water moves into the belt as soon as the soil reaches saturation and is held within them by surface tension. 

When the belt is on a slope (1-2%) or when the water in the soil reaches a critical head in the soil, the water in the grooves begins to flow, The movement of the capillary straw within the grooves creates a negative pressure that draws water in from the soil. 

This siphoning effect continues to drain the soil for as long as there is an effective capillary straw within the soil.  Capiphon™ literally sucks water up from the soil and siphons it off to waste or storage.  It draws water up through the pores in the soil by capillary action or “wicking”.  

       

The Capiphon will continue to drain when the belt is on a slight slope, or where there is a “tail” of the belt to create a head.  It will continue to drain, pulling water up from at least 5 cm below the belt in sandy loam soils; more in clays.

For this reason, water continues to flow for longer. Other systems relying solely on gravity, stop flowing when (or before) the head reaches zero. Capiphon™ continues to        draw water up against gravity due to the syphonic action.  Capiphon™ works with the soil particles so that flow rates are higher than flow rates than they are for slotted pipe, especially at lower head pressures.

The overall effect is that Capiphon removes 3-4 times more water per square metre than conventional drainage – and at lower cost!

          

 

Capillary and Syphonic Power Increase Efficiency

The theoretical flow rate due to gravity alone can be calculated from the permeability of the soil and the belt area. Capillary and syphonic power increase the flow rate by more than 3 times that of gravity alone in a sandy soil, and more than 30 times in clay soils!

 

Capiphon begins to flow sooner, flows for longer, and moves more water than other systems.
