Drainage Characteristics of Capiphon Belt and Pipe - Some Comparisons with slotted pipe with sock - 1116 KB

Paper presented to the International Commission on Irrigation & Drainage (Adelaide June 2012): Initial studies showed that Capiphon drainage technology out performs slotted pipe with sock (Drain Coil) in soil. It also had a higher flow-rate in free water at low hydraulic head. In soil when flooded, Capiphon commenced flow before, and continued to drain long after Drain Coil had ceased. Its capillary and syphonic action resulted in drawing water upwards, pulling the water table down to at least....

Capiphon Technical Features & Performance - 480 KB

Product Capiphon™ is a drainage material made from a special formulation of PVC that remains flexible and is long lasting. Capiphon™ has a series of grooves running down its length. The grooves are omega shaped with an internal diameter of one millimetre. The opening to the grooves is approximately 0.3 mm.

Capiphon Flow Rates - 438 KB

Flow rates quoted for agricultural (slotted) pipe are the capacity of the pipe to move water that
enters it. There is no direct performance standard for sub-surface drainage, however the minimum
requirement for the Australian Standard AS2439.1 for clear water opening is 1,500mm2/m. Capiphon’s
clear water opening (20,000mm2/m for 10cm belt) clearly exceeds that.

How to Use Capiphon as an Intercept Drain - 1992 KB

How to … Use Capiphon as an Intercept Drain The naming of drains is a difficult matter! There are many slight variations and some differences geographically. An intercept drain is simply a drain designed to intercept water flowing across the surface.

How to Use Capiphon behind a retaining or basement wall - 703 KB

A basement wall and a retaining wall are essentially the same except that the risk and cost of failure is much higher with a basement. Basement walls need to be drained properly to protect the building not only from leaks but from moisture (rising damp) seeping through the wall and damaging the interior. The exterior of the wall needs to be properly damp-proofed, starting with keeping water away from the wall itself.

Enhanced Biofilter Treatment of Stormwater by Optimizing the Residence Time (Redahegn Sileshi, Rober) - 317 KB

This paper describes the initial tests investigating the basic hydraulic properties and the clogging potential of Capiphon. A pilot-scale biofilter using a trough 3m long and 0.6 x 0.6m in cross section was used to test the variables affecting the drainage characteristics of Capiphon as an underdrain material (such as length, slope, hydraulic head, and type of sand media).

Examining the Clogging Potential of Underdrain Material for Stormwater Biofilter (Redahegn Sileshi) - 465 KB

The tests were conducted using two different species of green algal that were encouraged to grow in the biofilter device for several weeks before draining. The results indicated that the biofouling had only a small effect on the discharge rates, even though the algal growth was extensive

What Sand to Use? A Simple Permeability Test - 297 KB

What is “coarse sand”? There are different types of sand and they vary in their drainage performance. Table 1 has some of the Universal Soil Classification System (USCS) classifications with their permeability. The higher the permeability, the better the drainage. Here is a quick and simple test you can use to get the right sand for the job.

Serious Alternative to Ag Pipe

Ag pipe is also called aggie, agricultural pipe, ag line etc. Capiphon also out-performs slotted pipe.
