The equipment includes awater source connected by means of a water line with flexibleperforated popelines and a pressure adjuster connected to theinlet of the water line, and at the outlet - to the flexibleperforated water pipeline by a pipe connection to flexible waterpipeline. The individual flexible water pipelines are connected bymeans of unions to flexible water pipelines, and stoppers (10) arefitted to part of the holes of the flexible perforated waterlines.Adjuster (3) is housed by an external cylinder (13) with an inlet(14) and outlet (15) pipe. The cylinder (13) contains a spillway(16) centrally fitted, ending by an elbow (17) which is extendedoutward as a side outlet pipe (18).
