I'm desperately trying to find a supplier that carries the NDS EZ-Flow Drainage tubes:

I've called and emailed every supplier I know of, and no one seems to be able to help me. Anyone know where to find this product?

Associated Marketing is an NDS supplier in Philadelphia and they stock EZ Flow. Check with you local NDS rep for a supplier near you.

The NDS EZ FLow product is a great, gravel-less drainage system with many applications. Go to www.ndspro.com for more information on this product and where to get it.

How wide of a trench do you need to install the easy flow

Depending on the size of pipe and styrene aggregate, you will be at 7", 10" or 15" wide minimums. That will also correspond to depth, plus a typical 6" backfill. The 4" pipe encased in the 10" aggregate has been a good choice for swale and perimeter drainage applications.

I'm not convinced this product saves anything. We install a LOT of French drains. Typically about 4" wide trench. So the EZ Flow stuff would save us from having to haul in gravel and line the trench with landscape fabric. But as wide as it is, it would also mean we have to excavate and haul away a LOT more dirt than we normally would. So I think that's a loss, overall. I'd rather haul in wheelbarrows of new, clean drain rock than haul away more loads of soppy wet clay soil. I just can't see how this product saves me time or money overall.

Jim I agree, the goal today with issues in runoff and the need to conserve our ground water we as landscapers need to be installing drainage systems that catch water before they go into our community’s water supply or local bodies of water. I as well always use French drains and now rain gardens to manage drainage issues and unwanted run-off.

We used a knockoff fo the ez flow in aprogect last month. I noticed this thread looked it up thought it could work well for what we needed.
The back yard of the house we were working on is mid hill of a 4 house line and a 3-4 house area drains right through the back yard and accross into the woods. Horrible design by the developers. There was a river flowing during and amount of rain. So we build somewhat of a catch basin on the property line and that dropped down into 2 10 in ez flows that then ran underground and daylighted into the woods. Overall the product worked, and was easy to install (we had a excavator on site). The bad was it was hard to find (Twin Cities, MN) and the cost was very high for a 4inch drain tile wrapped in packing peanuts.
Overall I am undecided if I would use it again.

Well, we went through some certification classes today with NDS and got an opportunity to go over all of their products again. When we got to the EZ Flow, I stopped the presentation (it was a presentation just for our company) and started asking a lot of questions. Because, like I said above, I'm not real convinced this product saves me anything.

But as I started to understand the product better, my opinion started to change a little. I now feel there are some nice applications for this product.

For instance, installed underneath a lawn (especially in series, ever 5' or so) as a subsurface interceptor drain, I think would be a great application for relieving water saturation in soggy lawns. It would be done like this;

Another good application would be in French Drains. I am not quite as excited about using them in this capacity (in lieu of drain rock and pipe) because of the additional excavation and soil that would have to be removed. But, the good benefit of this product over using drain rock or river rock is that it increases the flow rate of water through it by 35%.

There are also some additional applications that are interesting. For instance, for use behind segmental retaining walls, instead of carting in gravel for drainage. Definitely big labor savings there.

Jim, I figured you would find enlightenment with additional research. I like to use the EZ Flow as a capture drain in swales and other low lying areas, and pipe it into a Flo-well or the "milk crates" Eco-Rain. http://www.ecorain.com/paginas/proyects.html

The EZ Flow captures and transports a great amount of water, easily and efficiently. As for the size of the excavation, sometime the 7" diameter product is sufficient, but the extra soil moved out for the 10" product eliminates the drainage issue, and around here, the soil is very valuable.

There are a myriad of products available in drainage, and most excel in a specific area, but are often marketed in too broad of an application. That NDS course is an excellent learning and potential profitable venture for anyone that works the soil. When approaching a property for any type of outdoor work, cutting, planting or building, soil and drainage should be on everyone's list to identify, work with, or correct.
