ALWASAIL WS-PDI combines the efficiency of surface drip irrigation with the flexibility of center pivot and linear move irrigation systems. While conventional center pivot and linear move irrigation water application packages are efficient and provide many different options for distributing water, WS-PDI technology provides increased system application efficiency through precision drip irrigation with the slow methodical release of water and nutrients directly to the soil area for optimal plant growth.
WS-PDI COMPONENTS
Based on the application, tall or short crop, the WS-PDI system components are blank polyethylene tubing, Thabit PC pressure-compensating heavy-wall dripline, and attachment fittings.
PRESSURE COMPENSATING (PC)
Thabit emitters incorporate a silicone membrane, which enables the delivery of precise and equal amounts of water over a broad pressure range.
Laser Welding Technology
This welding method prevents leaks in the event of extremely high pressures or in the event of the opening of the emitter during installation and/or retraction of the dripline in the field.
Drain (D) and Non-Drain (ND) Options
ND emitters eliminate drainage and refill effect, improving efficiency in pulse irrigation. In order to achieve the ND function, Thabit emitter opens at 0.40 bar and closes at 0.25 bar.
Anti-Siphon (AS) Options
The Anti-Siphon (AS) system is a specially designed mechanism that prevents suction of dirt and impurities into the emitter. The AS feature enables Techno PC Emitter to be installed underground (SDI), perfectly maintaining its irrigation characteristics and multi-year durability.
WS-PDI MANIFOLD
• Polyethylene tubing made from the highest quality linear low-density resins, UV and acid-resistant (black color).
• Pre-assembled fittings at 50, 55, 75, and 100 cm spacing.
• Tee fitting features one-piece construction for strength and durability, fits securely, and withstands heat, direct sun, and chemicals (brown color).

HOW DOES IT WORK?
WS-PDI consists of ALWASAIL’s Thabit PC dripline, which is attached to the end of a center pivot or linear move irrigation system’s rigid or flexible drop and/or a manifold (recommended) — whichever method is best for the crop being irrigated. The dripline is dragged through the crop by the center pivot or linear move system. As the dripline is pulled behind the system, the emitters deliver a uniform water pattern across the entire irrigated area. The water is applied directly to the soil surface, significantly reducing inefficiencies due to surface area and wind drift. This allows deeper percolation to the plant’s root zone.
DripNet PC dripline has pressure-compensating emitters welded to the internal wall of the dripline every 16 cm. These driplines are spaced at 50, 55, 75, and 100 cm between lateral lines depending on the soil type and the crop.
WS-PDI ADVANTAGES
- Potential for 20-30% water savings.
- Can be used on either tall or short crops.
- Significantly reduces evaporation and eliminates wind drift.
- Reduces and/or eliminates wheel track issues.
- Soil stays moist without crusting while soil compaction is reduced or eliminated.
- Increases soil moisture resulting in more water banked into the soil profile.
- Reduces plugged and frozen nozzles during winter watering.
SHORT CROP APPLICATIONS
Unique WS-PDI manifold system attaches directly to the pivot’s rigid or flexible drop for successful irrigation of crops such as soybeans, wheat, potatoes, onions, and alfalfa.
TALL CROP APPLICATIONS
WS-PDI dripline
(Thabit PC) attaches directly to the pivot’s rigid or flexible drop for successful irrigation of crops such as corn and small grains.
