Dense Plantings
Table 5-1 shows that for dense plantings, the best choices of emission devices are
Landscape Dripline, Xeri-Sprays and Xeri-Pops. Each of these choices has
advantages for certain applications, however Landscape Dripline is certainly the
most water efficient because it does not spray any water into the air.

Landscape Dripline
Inline emitter tubing is polyethylene distribution tubing with emitters pre-
installed at the factory at preset intervals. Rain Bird's Landscape Dripline goes
further than today's conventional inline tubing products because it provides
unmatched clog resistance and lowers installation costs.
* See following pages for more information on choosing an emission device.
