The present disclosure provides formulation. The formulation contains a high density polyethylene composition containing (i) a high molecular weight component including an ethylene/a-olefin copolymer, the high molecular weight component having a density from 0.924 to 0.930 g/cc and a high load melt index (121) from 0.3 to 0.9 g/10 min; and (ii) a low molecular weight component including an ethylene-based polymer selected from the group consisting of an ethylene homopolymer and an ethylene/a-olefin copolymer. The high density polyethylene composition has (a) a density from 0.950 to 0.956 g/cc; (b) a high load melt index (121) from 15 to 28 g/10 min; (c) an 121/12 of at least 85; (d) a notched constant tensile load failure time at 35% yield stress of greater than 90 hours; and (e) an environmental stress crack resistance (ESCR) F0 value, according to ASTM D1693-condition B (100% IGEPAL), of greater than 2,000 hours.

Various systems, methods and apparatus for locating emitters embedded in tubing are disclosed herein, as well as forming outlets in said tubing and confirming the placement accuracy of such outlets. In one form, an emitter locator is disclosed having: a housing defining a generally enclosed space and having an inlet located in a first side of the housing and an outlet located in a second side of the housing positioned opposite the inlet; a cutter positioned within the generally enclosed space between the inlet and outlet; a first optical instrument located proximate the inlet; a second optical instrument located proximate the outlet; and a controller connected to the cutter and first and second optical instruments, the controller configured to detect a tubing target area desired for placement of an outlet opening in tubing that passes through the inlet and cut the tubing target area to form the outlet opening therein.

The present invention is a system for treating land, either to reclaim or optimize the land. Embedded subsurface pipes deliver water to the land. The water may be loaded with soil-treating additives. As water streams from the pipes, it treats the land before passing into a drainage ditch around the periphery of the land. The water is removed from the ditch and recycled, removing contaminants (in reclamation operations) or adding more additives (in optimization operations), before returning to the pipes for another round of treatment, if necessary.
