In a lecture I heard recently, Leigh Jerrard of the Greywater Corp mentioned an intriguing product from Australia: a dripline compatible with greywater. Now, if you tried to push gunky greywater through conventional dripline it would clog in seconds. According to the manufacturer, Netafim Tiran Greywater Dripline gets around this problem because,
Each dripper has its own mini filter. When a contaminant attempts to enter the emmitter, it is rejected by the emitter and simply remains in the tube. The irrigation system should be flushed once a year, however anecdotal evidence indicates that flushing may only be required every 5 years.
100 meters of Netafim costs 100 Australian dollars excluding tax, or about .30 USD a foot. Not a bad price if it performs as advertised.
Some quick Googling failed to turn up a US distributor. Root Simple reader Rachel wrote to point out Netafim’s distributor locatoer: http://www.netafimusa.com/wastewater/support/locator.
To use Netafim you need to add a filter as you do with every drip system. I could see this product working nicely with Art Ludwig’s Laundry to Landscape system.
If any of you have worked with Netafim, leave a comment.
