  • Multiple-slopes may be entered for laterals, submains, and mainlines
  • Submains and mainlines may be telescoped with multiple pipe sizes
  • The Project Size is available in the Project Report and summarizes the acreage of all blocks in a project’s multi-block design
  • A diagram or image file can be added to the Customer description
  • Designs may be easily saved, exported and imported

To further streamline the drip irrigation design process, Toro has created a drip irrigation product database for Irricad Software.  The database includes the following drip irrigation products: Aqua-Traxx drip tape, Aqua-Traxx PC (pressure-compensating) drip tape, Neptune flat emitter dripline, BlueLine Classic dripline, and BlueLine PC dripline.  Click here to download Toro’s drip irrigation product database for Irricad.  Once this file has been downloaded, extract the .mdb file to your Irricad database folder and access it when designing drip tape and dripline laterals.  AquaFlow may also be used in tandem with Irricad software, and is especially valuable in accelerating the drip tape / dripline lateral selection process.

Note: In order to achieve the best possible results, we encourage that final irrigation designs be performed by an authorized dealer. To find your nearest authorized dealer, contact us at
