Performance Solution

   •   The design has considered site and soil conditions and has also been discussed with the
       landowner.

   •   Irrigation area has been designed using correct DIR.

   •   The spray from the sprinklers shall not exceed 500mm in height, 2000mm in dia. (1m
       throw) and be heavy droplet in nature that prevents misting and drift. Control valves may be
       needed to adjust the flow and pressure to achieve this.

   •   All pipework and materials used are to be new, meet relevant standards and be fit for use.

   •   Category 4 soils or better will assist in even distribution of treated effluent.
