    Got a client who owns a hotel. Has a narrow strip of turf in between breezeway and parking lot. He's asked us to install irrigation, new soil and new turf. I was thinking of using Netafim Drip lines under the turf instead of sprays to keep water off the walk way, and in turn, reduce his liability in case of someone "slipping and falling" on a wet sidewalk. Has anyone here ever done subsurface irrigation under turf with drip line? Any input would be appreciated!
     
  2. Hey fellow TX I know the TAMU irrigation school was doing a study but I can't seem to locate it. Try contacting or hunting through this link.

    My 2 cents? If you can put it down on level stable uniformly packed soil prior to adding soil and sod it can work assuming you space properly etc. Stagger the drippers in a triangular pattern. If you trench it in the water is going to flow along the ditch line and not uniformly. The netafim site has great info as well. Multicycling is very important as well to get the water to spread laterally and not just go down. This is not purely a design thing as some would want to believe. It takes 1/3 experience 1/3 common sense and 1/3 design inmo.

    Make absolutely certain you have a signed "No Aerating!" agreement if you use sub-surface drip.

    If installed properly, at the right depth, and with proper back filling, the lawn can be aerated. I have a handful of sub-surface systems that we maintain and some of them get aerated. It's all in the execution of installation. As with any system. Heck I've repaired laterals and mainlines for traditional systems that were hit be an aerator.

    It would depend on the soil. I see lawns where the grass roots aren't anywhere near as deep as aerating tines penetrate.

    That's why the best execution for installing subsurface, it to remove 6"-10" of existing soil, and fill back in with good soil.

    Nice work if you can get it. I don't want to see the "builder's system" version of sub-surface drip.

    Unfortunately, I have. I do also have 2 systems that cannot be aerated due to lack of proper installation. But everything else on the systems is hacked as well.
