A lapeta pipe is a flexible, lightweight, flat tube made from high-density polyethylene (HDPE) plastic, primarily used in agriculture for water conveyance, particularly in areas with uneven terrain, as it can be easily laid out and transported due to its flat design; essentially a "lay flat" irrigation pipe that can be rolled up for storage and is commonly used for delivering water to crops in farms through sprinkler systems.

It's offered in a wide range of diameters with integral welded connectors which ensure a leak-proof connection. 

It's proven to reduce the overall material and labor costs of an entire irrigation system.
