A lateral pipe (dripline) is the final irrigation line that delivers water directly from the submain to the plant root zone through built-in emitters. It ensures controlled, uniform, and efficient water application in drip irrigation systems.
Product Description
Full Description:
A lateral pipe, commonly called a dripline, is the final water distribution component in a drip irrigation system. It receives water from the submain pipeline and delivers it directly to the plant root zone through built-in emitters or drippers installed at regular spacing along the pipe.
The main function of the lateral pipe is to ensure precise, uniform, and controlled water application to crops. Unlike mainlines and submains that transport water over longer distances, the lateral pipe operates at field level and is responsible for the actual irrigation of plants.
Lateral pipes are typically made from flexible low-density polyethylene (LDPE) or similar materials designed for field installation. They are laid along crop rows either on the soil surface or slightly buried, depending on the irrigation design and farming practice.
Inside the pipe, emitters regulate water discharge at low flow rates (commonly 1.6 L/h, 2 L/h, or 4 L/h), ensuring slow and efficient water delivery directly to the soil. This reduces water loss through evaporation, runoff, and deep percolation, making drip irrigation one of the most efficient irrigation methods.
Proper design of lateral pipes is essential for uniform irrigation. Factors such as pipe diameter, emitter spacing, line length, pressure, slope, and water quality all affect performance. If the lateral is too long or poorly designed, pressure loss can cause uneven water distribution along the row.
Lateral pipes are widely used in vegetable farming, orchards, vineyards, greenhouses, nurseries, and row crop agriculture. They are especially important in precision agriculture systems where water and fertilizer (fertigation) must be applied accurately to each plant.
Before installation, users should confirm specifications such as pipe diameter (16 mm, 20 mm, etc.), emitter flow rate, spacing, wall thickness, pressure rating, UV resistance, and compatibility with submain connectors and field conditions.
