A web-based application has been developed to optimize the design of main pipe in a pressurized irrigation system, with several submains connected to it and operating simultaneously. The software uses routine procedures generally adopted in drip main design and advancements in software development methodologies to optimize the design of drip irrigation mains. The software features an easy-to-use interface which makes it easy for non-technical users to navigate the software and create main designs without needing extensive training or expertise. The design report can be downloaded in the user-required format. Additionally, the software has the capability to visually depict pressure head distribution curves, required pressure head, and ground profile in a more usable and intuitive way for designers. Pre-processing of input data for the web application is minimal. The application has undergone several tests using different sample data covering all use cases to ensure its accuracy and reliability.
