The Business of Mobile Irrigation

By Abraham Salomon, Founder, Agriworks Uganda

Abraham Salomon participated in the 2014 International Development Design Summit in Arusha, Tanzania and is an active member of the International Development Innovation Network.

There is a large gap in the market for irrigation technologies serving smallholder farmers. Between treadle pumps and large commercial systems, farmers are left without easy, affordable irrigation solutions.

Agriworks Uganda is a startup company, developing innovative technologies for smallholder farmers. The business conducts research & development (R&D) targeting this market, and develops low-cost sales models to reach them.

Our product line addresses a large gap in the market for irrigation products suitable for smallholders. Competing products for our customer segment do not meet the needs of our clients. These options can be classified into low-cost manual systems, and high-cost fixed systems. The low-cost manual systems are well known, as treadle pumps, bicycle powered pumps, and manually-filled drip bucket-kits. Although the capital cost of these is significantly lower than our offerings, they are in a much lower power class and cannot irrigate commercially viable acreages. These systems require extremely large amounts of labor to operate and are feasible only within a vary short distance to water. Because of these problems, many farmers have abandoned these systems, often in favor of small engine pumps. In the region, small engine pumps also have not been successful, as they are sold without a complete irrigation design.


Farmers often use a pump to operate a small sprinkler (usually poor quality) or hand water with a garden hose. Because buying a pump cannot solve the problem of effective water delivery, these systems are also highly fuel and labor inefficient. Competitors offering these products are generally small p
ower-tool sockists who have very minimal knowledge on irrigation and let their clients down with unmet promises. Finally, expensive fixed irrigation systemsare offered by a few specialty irrigation suppliers, but these are out of the reach of most smallholders. They serve the middle and upper income class of hobby farmers as well as large commercial farms. These companies have large overheads to gain consumer confidence of these customer segments and are not well suited to the smallholder market.

Our flagship product is the Agriworks Mobile Irrigation System (AMIS), which is a full irrigation system that can be carried by a common motorcycle.

This innovation is the cheapest irrigation technology on a per-acre basis that we know of. It is designed to allow more than one farmer to share the capital cost of the system, making irrigation much affordable for each user. It also has a number of other benefits: because it is mobile, all the equipment is securely stored at night and guarded against theft; it is easy to use, and needs only one operator in addition to the farmer; finally, it comes with a motorcycle that can also be used to take crops to market and for personal transport. We’ve been working on this technology for over 5 years, with the idea starting in a UC Davis’ D-Lab team. Since we built the initial prototype in Uganda, we’ve continued working with D-Lab to improve useability before commercial release. The product is now ready for scale out, and a release event is in the works.

During Fall 2014, two volunteers from our partners at the UC Davis D-Lab have joined us to fabricate and test the final design and release the Agriworks Mobile Irrigation System (AMIS). The goal of the trip was to build a prototype of the commercial model, test it with farmers, make changes based on their feedback, then build the commercial model for release.

TheUntitled2 design consists of a frame which holds the pump, 100 meters of layflat hose, and a toolbox for the sprinkler head, booster pump, spare parts, and spanners. We tested the commercial model in four sites (Ngora, Mbale. Jinja, & Abim districts) among farmers having different levels of experience in irrigation. In Ngora, we tried the commercial model on a bajaj boxer, the motorcycle we’ve been trying to adapt the system to for the last year. We wanted to use this motorcycle because it is by far the most common motorcycle in Uganda, and is known for being long-lasting, durable, and easily repaired. For these reasons, we’ve tried all means to make it work for the AMIS, but during this trial, we decided it just does not have enough power to make the system work efficiently. The RPMs needed to make reach our sprinkler’s desired operating pressure causes too much strain on the 100cc engine.

In Mbale, we operated the system with a CG125, which performs very well. Although the drawbacks of this motorcycle are the higher fuel consumption during transport and fewer sales outlets for spares, we see this model performing far better during irrigation and transporting the heavy load of equipment on the road. We’ve settled on this model and will include it in the sales price of our final AMIS product. The test in Jinja was the first flawless run of the system we’ve ever done. Within 20 minutes, we’d gone to the stream, set up the entire system and began irrigation. The performance was excellent, and we irrigated ½ acre for the first time. Finally, in Abim, we had no additional problems with the system, and the farmers we tested with gave us good information on their price point to buy the system. Although it was not for sale, they told us if we had been willing to sell it at 6 million shillings (roughly $2,300), we would not have gone home with the AMIS.

General feedback was that all the farmers we tested with were awed by the system and found it easy to use, effective, and a major upgrade from their existing practice. However, the system price was high, and many farmers will have to access loans to get the system. Some farmers mentioned it was going to be possible for them to buy the system outright, especially in small groups of 2-5 people.

Based on the feedback, we’ve made some changes on the system before our final release. This includes making the sprinkler’s tripod more resistant to falling, changing size and the position of handles on the toolbox, reducing the number of straps for attaching to the motorcycle, and replacing all threaded fittings with camlocks. This should make the system more efficient and easy to use.

To offer lower cost alternatives to the AMIS, we’ve also developed a full product line of the AMIS plus three other mobile irrigation technologies. The four products are all based on the AMIS’s integrated water delivery system, the motorcycle mounted pump/pipe frame. Because of this design, they are fully modular, allowing a farmer to start with one system and add on the others or upgrade to more powerful versions over time. The first is a cut-down version of the AMIS, which has a stronger delivery pump and no booster. This will work well in flat areas, and can bes sold without a motorcycle. Second, we have designed a drip-system where every user must buy a ¼ acre drip-kit, but the multiple users can share a mobile water delivery system. This mobile delivery system is the same as what we use on the original AMIS, supplying water to the main-line of various farmers’ drip kits each day.

Finally, we have designed a moveable impact sprinkler set, which requires lower pressure to operate. This also uses the AMIS mobile delivery system, and the sprinkler-set can be carried easily by hand from one plot to another (within ~1 km). Because they are modular, a farmer starting with a drip kit can cheaply upgrade to a full AMIS, purchase 4 drip kits (for 1 acre), or combine sprinkler-sets with drip and rain guns in any way they prefer. Each of these will have it’s own price tag and site requirements, but based on these visits, I think there will be customers for all of them. Agriworks may need to incluUntitled3de rainwater capture ponds as a product for upland smallholders to access the system.

We plan to finish the R&D on these products, and launch by the end of the year. In order to do this, we are in the process of establishing agreements with agents to market these products for us, and identifying finance organizations willing offer these products on an asset-lease basis. Based on our extensive work in R&D for our target clients (commercial smallholders), we think we can be the market leader in small-scale irrigation in Uganda, and eventually, East Africa.

Applications to be an international organizer with IDDS are now open!

Currently, there are two IDIN funded organizing teams that need extra support to help organize their summit. The IDDS Waste summit (which will be held in Cali, Colombia from June 14 – June 29) is looking for 4 Design Facilitators and remote support leading up to the summit from a Communications Organizer, Participant Supporter, and Fundraiser. While the IDDS D’Kar summit (which will be held in D’Kar, Botswana from August 15-30) is looking for one Experience Coordinator, 2 Design Facilitators with Prototyping and CCB experience, and 2 Design Facilitators with Business and Venture Development experience to assist them both leading up to the summit and at the summit in D’Kar.

What is an organizer?

An IDDS organizer is someone who not only organizes an IDDS, but also embodies IDDS and represents it well.  Organizers are there to set the example, add to the participants’ overall experience, build friendships, and foster the IDDS spirit throughout every component of organizing the summit.  An IDDS organizer is not responsible for having all of the answers, but they are expected to know whom to refer people to when they have questions (e.g. who do I contact about housing and meals? health and safety? projects?, etc.).  All international organizers must have attended an entire IDDS or themed summit before.

What’s the time commitment?

The specific amount of time will vary per summit and organizing team.  In general, however, organizers meet weekly months leading up to a summit to become acquainted with each other and prepare for the event.  During the summit, organizers meet almost daily and live with participants at the main venue and in the communities as well.  It is expected an organizer will spend 5-10 hours a week leading up to a summit working remotely with a global team to prepare the summit curriculum and participants, they will arrive to the summit venue about 1 week before hand for preparation and any last minute training, stay through entire summit, and remains at least two days after to help send off participants and close the summit out.   The ideal IDDS organizer is then forever linked with their summit – happy to serve as a link to their project teams and communities for any opportunities IDIN may have to share after the summit.


What would be my role?

Though IDDS operates under a more collaborative and flat structure, there are key lead organizing roles and several other important roles an organizer can fill.  This year, when you apply to be an international organizer, you will apply to fill a specific role.   Though you are applying for a specific role, it is expected you will work closely and collaboratively with the rest of the IDDS organizing team – helping out others when they need extra hands in the true IDDS way.  Read more here about how IDDS Organizing Roles operate.

What roles are open and available?

Each of the roles listed below are volunteer opportunities. If your role is expected to be at the summit, the organizing team would cover the cost of your travel, food, and board during the experience.

The IDDS Waste team is looking for:

  • Four Design Facilitators – Read about the complete role of the Design Facilitator here. Specifically, the team is in need of people with technical design skills and strong interest or background in waste. Likewise, the team is also looking for people who can serve in more roles that just design facilitator – so it is helpful to mention in your application what other roles you are able to contribute to. This person must be proficient in Spanish and English.
  • Communications Organizer: Read about the complete role of the Communications Organizer here. Specifically, the team needs someone to help with communications leading up to the summit. This would be a remote role and you would not be expected to attend the summit. This person must be proficient in Spanish and English.
  • Participant Supporter: Read about the complete role of the Participant Supporter here. Specifically, the team needs one person to help participants only until before the summit. This would be a remote role and you would not be expected to attend the summit. During the summit the team will have local organizers supporting participants. This person must be proficient in Spanish and English.
  • Fundraising and Sponsorship Coordinator: The team needs someone to help us find funding and sponsorships for the summit. This person would work closely with the lead organizer and should enjoy interacting with various stakeholders. This would be a remote role and you would not be expected to attend the summit. This person must be proficient in Spanish and English.

The IDDS D’Kar team is looking for:

  • Experience Coordinator –Read about the complete role of the Experience Coordinator here. The organizing team prefers this role to be a female past participant (to keep a gender balance on the leadership team) and have experience leading and guiding participants before.
  • Two Design Facilitators with Prototyping and Creative Capacity Building experience – The team needs preferably one female and male from the developing world to serve as design facilitators. Read about the complete role of Design Facilitator here.
  • Two Design Facilitators – with Business and Venture Development background – The team needs preferably one female and male from the developing world to serve as design facilitators. Read about the complete role of Design Facilitator here.

What are the eligibility requirements?

In order for your application to be considered, you must:

  • Have attended at least one IDDS before
  • Complete the international organizer application form
  • Turn in your application by October 31, 2014 at 5pm EST.

Any incomplete applications or applications received after 5pm on October 31, 2014 will not be considered.

What is the selection process like?

Applications will be reviewed first by the IDDS Waste organizing team and the IDDS D’Kar organizing team, respectively. Based on the needs of their summit and the budget available, the organizing team will make their selections and submit them to the IDIN Summits Advisory Committee for approval (to ensure there is no conflict of interest). International organizers can expect to be notified of their status in mid to late November.

What do I do now?

Applications are open now! Review the available summits and roles and apply online here by October 31, 2014 at 5pm EST.


What do I do if I want to help out, but cannot attend the summit? 

If you wish to help out a summit (or multiple summits) remotely, there are still many other opportunities for you!  Simply fill out the survey here and your name will be added to a repository that organizing teams can use to share other opportunities (such as reviewing applications, advertising summits, translating documents, designing logos, helping develop health guidelines, etc.) as they arise.
