About Drip Irrigation Index
Drip Irrigation Index is an English-language reference for choosing and comparing drip irrigation equipment. It is published by Qualitora LLC.
How we compare tape
We start with the exact model code and identify the manufacturer’s document and revision. We retain the pressure attached to flow and the slope and uniformity attached to row length. If a figure can only be found for a product family, we identify that family.
Manufacturer data and seller listings are cited separately. When they give different figures, we display the difference and the conditions each source supplies.
The index covers selected US-market models from Rivulis, Toro, Netafim and Irritec. Each model page links to the relevant manufacturer documents, including their revision and the date checked. Model listings describe published configurations. Confirm current availability with the supplier.
Browse the tape index or download the specifications and source URLs (CSV).
How we calculate flow
The calculator uses published nominal rates or a rate you enter. It estimates demand for the total length of tape at that rate. For layout and fitting decisions, check the tape and fitting manufacturers’ documentation and measure your system while it runs.
See the method in the Rivulis and Toro comparison.
Privacy and contact
Calculator inputs and changes to the index filters stay in your browser. A model search from the home page is included in the index URL. Cloudflare serves these pages and processes connection data to deliver and secure the site. See the Cloudflare Privacy Policy for details about its services.
When a page links to a retailer, the link passes through a short redirect on this site that counts the click. The count records the retailer, the page the click came from and the country of the request. It stores no IP address and sets no cookie.
No retailer pays Drip Irrigation Index for these links today. Each page that carries retailer links says whether one of them pays. Kits are listed by price, lowest first, whether or not a link pays.
