AquaFlow 4.1 – Drip Irrigation Design Software

AquaFlow drip irrigation design program

Welcome to AquaFlow!

AquaFlow is Toro’s FREE drip irrigation design software that provides irrigation designers with a state-of-the-art tool to configure drip irrigation systems for optimum performance.

AquaFlow 4.1’s latest desktop platform upgrade provides faster performance and a smaller local installation than previous versions, as well browser compatibility improvements.  In addition, AquaFlow 4.1 helps users remain within Toro emission device operating specifications.

AquaFlow is now also available as a tablet app for both Apple and Android tablet devices. The AquaFlow app is an innovative solution that greatly simplifies the drip irrigation design process and improves accessibility to otherwise complicated drip irrigation design information.

AquaFlow App for Tablets - Drip Irrigation Design Mobile App

The all-new AquaFlow app for tablets creates a more powerful and convenient user experience, as it’s fully integrated across all software platforms – from tablet to desktop. Users can quickly and easily choose laterals and submains, and instantly view results in tables, graphs and a visually friendly, color-coded uniformity map. AquaFlow even allows users to weigh various design options with one-click, to easily compare one lateral choice versus another.


AquaFlow drip irrigation design software can be accessed and used online or downloaded to your computer or tablet device for offline use. To become a registered user, visit the AquaFlow home page, accept the User Agreement, and fill all the fields in the Registration Form.


AquaFlow’s tablet app can be downloaded onto your Apple or Android tablet device from the Apple or Google storefronts.

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, FlowControl drip tape including the newest 0.13 gph flow rate, 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
