Agriworks Mobile Irrigation Systems
Agriworks Mobile Irrigation Systems (AMIS) is a mobile irrigation system for smallholder farmers.
Agriworks Mobile Irrigation Systems (AMIS) are mobile, modular systems capable of irrigating 1 – 6 acres of land. The system can be shared by more than one farmer, and customers can spread the cost while still being able to irrigate commercial-sized plots. Two base systems and three different AMIS attachments are offered to meet specific smallholder needs. There are three basic systems: AMIS-Foundation, AMIS-extra and AMIS-50. Each system can be combined with either of these three components: the AMIS-MVUA KALI (rain gun), AMIS-DRIP (drip irrigation kit), and AMIS-IMPACT (sprinklers). The systems are designed to ride on the back of a motorcycle or cart and can deliver water up to 200 meters+ from a water source.
Less than $800 per hectare with Agriworks Mobile Irrigation
Goal 2: Aims to improve food security by allowing farmers to irrigate more land, ultimately allowing them to harvest more crops.
The system is oriented towards small farm holders, 1-6 farmers can share the cost of a system which moves from farm to farm.
Agriworks Uganda manufactures these systems on a per-order basis.
Interested buyers can request a demonstration of the AMIS systems. If they decide to purchase, Agriworks Uganda sells on a ‘lease-to-own’ basis.
Description of the pump type
Land size irrigation capacity, measured in acres
The amount of water discharged, measured in liters per minute
Maximum length of pipe from pump to the raised tank, measured in meters
The amount of pressure required to pump water, measured in MPa
The maximum length of pipe from the water source, measured in meters
Type of energy used to power the pump
Maximum power requirement, measured in watts
Maximum motor current, measured in amperes
Power required to run the pump, measured in voltage
Since the product is modular there are different system configurations. The AMIS-FOUNDATION is the most basic and affordable of the Agriworks systems and can hold up to 160 meters of pipe. Based on this frame, the customer can add on different units:
1)Rain gun sprinkler – Uses a booster pump mounted on a modified motorcycle to irrigate up to 6 acres.
2)Impact Sprinklers – Uses rapid-connect pipes and 4 low-pressure sprinklers to irrigate up to 4 acres
3)Drip Kit – The AMIS-frame Connects to 1/8 to 1 acre drip kits installed in the field (up to 8 kits per day).
The AMIS-50 is a more powerful system that utilizes a higher pressure pump and can also hold up to 160 meters of pipe. If purchased as a standalone system, it comes with 100 meters of pipe and a rain gun.
Both the AMIS-FOUNDATION and AMIS-50 can be operated by a single person, are capable of irrigating up to 2 acres per day, and include a tool kit to make small repairs. Once a customer has the AMIS-FOUNDATION or they can upgrade to other AMIS products.
The AMIS-MVUA KALI is the most powerful AMIS system. It uses the AMIS-FOUNDATION, combined with a booster pump powered by a 125 cc motorcycle (included). This system requires two people to operate and can irrigate land over 100-200 meters from a water source (depending on terrain).
The AMIS-IMPACT is designed to operate with low pressure using small impact sprinklers. This system can irrigate up to 1.5 acres per day and reach plots 110-170 meters from a water source.
The AMIS-DRIP is for farmers wanting the precision and efficiency drip irrigation offers. Water is delivered by the AMIS-FOUNDATION to a 1/4 acre plot, which can be expanded up to 4.5 acres. Farmers can also purchase their own drip-irrigation system and power it with the AMIS-FOUNDATION.

Unknown. The longevity of the system mainly depends on the pumps used to operate the different systems.
Irrigation of 1 to 6 acres per day depending on systems used.
Rain gun sprinkler (AMIS Mvua-Kali) – Uses a booster pump mounted on a modified motorcycle to irrigate up to 6 acres.
Impact Sprinklers (AMIS–Impact) – Uses rapid-connect pipes and 4 low-pressure sprinklers to irrigate up to 4 acres
Drip Kit (AMIS Drip’) – The AMIS-frame Connects to 1/8 to 1 acre drip kits installed in the field (up to 8 kits per day).
Universtiy of California, Davis’s D-Lab has worked extensively with Agirworks Uganda and has tested the AMIS systems and provided recommendations for improvements.
Mounting a system on the back of a motorcycle poses some safety concerns, but no safety assessments have been made thus far.
The additional components include the AMIS Mvua-Kali, the AMIS Impact, and AMIS Drip. The AMIS Mvua-Kali is a rain gun attachment for up to 6 acres. AMIS Impact is a smaller sprinkler for uneven and odd shaped plots. Lastly, the AMIS Drip is a drip irrigation set for highly efficient irrigation.
