Deep Root Watering (DRW) System is a 75mm diameter, double wall coil pipe with corrugated outer wall to deep water tree roots. The internal volume is 26L throughout and allows controlled percolation throughout the entire root zone over a 24 hour period.

Installation Instructions

1.  Excavate  a   1,2(w)  x  1,2m(l)  x  1m(d)  treehole  for  100L-500L  trees;  1,6(w)  x  1,6m(l)  x  1m(d)  hole  for  1000L  trees.
2.  Backfill the treehole with  300mm of  topsoil/Zeoplant blend. For  a  1m3  tree hole,  mix  30kg  of  Zeoplant into backfill  (See  www.zeoplant.co.za).
3.  Slide  DRW  system  into  the  hole.
4. The  DRW  system  rest  on  300mm  topsoil/Zeoplant  blend.
5. Place  tree  into  the  center  of  the  unit  and  treehole.
6. Fill treehole gradually with  balance of  topsoil/Zeoplant blend and  spread  strings throughout as  filling progresses.
7. Only  the  water  inlet  to  be  visible  above  ground  after  filling.
8. Fill  pipe  with  water  to  the  brim  every  second  day.
9. Ensure  that  sliding  cap  is  closed  when  not  in  use  to  prevent  undesired  objects  entering  the  pipe.
