Ezy-Drain
While great advances have been made in wastewater technology, land drainage remains
reliant on traditional techniques.
Now Klargester can offer the Ezy-Drain system, a revolutionary new product that redefines
the method of dispersing water into soil.
Utilising recycled synthetics packed around sectional tubes, the Ezy-Drain
design offers a packaged solution to avoid the drawbacks of using loose quarried
aggregates. The resultant benefits are an extremely lightweight system that can
be rapidly installed without the need for specialist skills.
Applications
Treatment Plants and Septic Tanks: Ezy-Drain replaces the perforated pipework
of a 'herring-bone' drainage field. Ezy-Drain's storage and flow
charecteristics typically achieve 35% more surface area than natural aggregates,
resulting in enhanced water treatment capabilities and a reduction in long term
clogging.
Effluent Drainage: Ezy-Drain may replace traditional 'carrier' drainage
from a treatment plant to discharge point.
Seasonal Soakaways: Ezy-Drain is ideal to install as a 'seasonal soakaway'
flowing from a treatment plant. A seasonal soakaway allows infiltration of treated
effluent where ground conditions permit or transfers effluent to an alternative
discharge point when ground conditions are unfavourable.
Trench excavated to site specific requirements arisings kept for re-use.
3m Ezy-Drain sections are lightweight and easily handled.
Ezy-Drain sections are simply joined together using click fit connectors* Joints
may be protected by the optional polystyrene collars or simply backfilled with as-dug
material.
Arisings used to backfill to top of trench.
Assembled Ezy-Drain system is then rolled into the dug trench.

Benefits
Soil Porosity
To establish the overall length of a drain run required, a soil porosity test may be necessary. The following procedure should be adopted:
Repeat this exercise two more times with at least two trial holes. Calculate the average time.
By reference to the table below, the length of drain run required for various capacity tanks may be established.
Drainage field disposal should only be used on test values (Vp) between 12 and 100. Where a Vp value falls outside these limits, our technical team can advise.

The table indicates typical meterage for domestic septic tank applications, assuming a trench width of 450mm. Approximately 20% less drainage is required for Sewage Treatment Plants as treated effluent is of a higher standard. For other applications and further information, please consult Klargester.
Design The Ezy-Drain comprises of sections of twin wall perforated plastic pipe, surrounded by a synthetic aggregate, wrapped in polyethylene netting. Each 3-metre section is simply joined together by the use of click-fit connectors, protected by a preformed collar. The synthentic aggregate is manufactured from recycled expanded polystyrene, engineered to deliver optimum performance while consistently retaining its form. Delivery & Installation Ezy-Drain is entirely prefabricated and delivered in 3-metre sections directly to site. Installation can be performed by a single person without the need for aggregate, with trenches only requiring backfilling prior to immediate operation.
