For more than 100 years, the U.S. Bureau of Reclamation has brought water to arid lands to support agriculture and economic development. Today, Reclamation’s 8,000 miles of canals deliver water across the Western U.S., serving over 30 million customers and 10 million acres of farmland that produce 60% of the nation's vegetables and 25% of its fruits and nuts.
As water is conveyed by a canal from the source to customers, some water losses (such as from evaporation) are inevitable. However, a much more significant and preventable type of loss is seepage of water from a canal into the ground. Seepage represents the most significant cause of water loss in canals, reducing the efficiency of water deliveries and increasing costs for Reclamation and its customers. Moreover, if not adequately addressed, seepage can result in a canal failure over the long term.
The $360,000 Water America’s Crops Challenge seeks to incentivize new approaches to minimizing seepage in canals that are cost-effective for the farmers and communities that Reclamation serves. The challenge is designed to accelerate development of new solutions and validate performance on criteria that will be critical for field testing and future deployment.
The challenge will have two (2) phases over 24 months. In Phase 1, solvers will have six months after the challenge launch to submit technical proposals describing their solution, including expected performance on key criteria of effectiveness, durability, maintenance requirements, installation requirements, and cost. Up to five (5) finalists will be chosen to develop a prototype (lab-scale) version of their solution in Phase 2 for testing at Reclamation labs. Finalists will have nine (9) months to develop their prototypes, and each finalist will receive $50,000 to support solution development. Following laboratory testing in Phase 2, a judging panel will evaluate the results, and determine the winner(s). Up to one (1) first place winner will receive $90,000 and one (1) runner-up will receive $20,000. Winners are expected to be announced in January 2023.

Background
For more than 100 years, Reclamation has brought water to arid lands for agricultural and economic development. Today, Reclamation operates 8,116 miles of canals that deliver water across six regions of the Western U.S. (see map), serving over 30 million customers and 10 million acres of farmland that produce 60% of the nation's vegetables and 25% of its fruits and nuts.
As water is conveyed by a canal from the source to customers, some water losses are inevitable. Evaporation of water into the air and transpiration (or absorption) of water into nearby plant life create very minimal water losses along canals. However, the most significant type of water loss in canals is seepage of water through the base or walls of a canal into the subsurface or subgrade. Seepage may be diffuse (through permeable soils), concentrated (through bedrock fractures), or some combination thereof. Rates of seepage can be affected by many factors, including:
Whether a canal is lined;
The material used for lining (e.g. concrete or plastic);
The composition of the subsurface or subgrade (e.g. fine-grained soil, coarse soil, or various types of bedrock);
The level of the groundwater table; and
Climatic conditions including temperature, humidity, and precipitation.
Seepage that is not adequately addressed can result in canal failure. In addition, efficient and effective use of water resources becomes even more critical as populations grow and communities face more extreme droughts, floods, and other climate impacts.
Typically, customers and communities that receive water deliveries must pay project costs for operation and maintenance, and addressing repair and maintenance of aging infrastructure can be expensive. As a result, the cost-effectiveness of any solution to water seepage from canals is a key criteria for successful deployment across communities that Reclamation serves.
Reclamation continues to evaluate and improve canal infrastructure by examining a variety of methods and technologies to address seepage. The key criteria necessary for a successful solution include:
Effectiveness at reducing seepage
Durability over time and in various environmental conditions
Minimal maintenance requirements
Ease of installation in a variety of environmental conditions and locations
Cost-effectiveness (including both cost of materials and costs related to the other four performance criteria)
Based on Reclamation’s analysis and experience in the field, some existing approaches perform very well on certain criteria, but no existing approaches achieve excellent performance on all of the criteria. Table 1 below summarizes Reclamation’s findings regarding the performance of several existing methods for reducing water seepage from canals.
In this challenge, Reclamation seeks solutions that improve upon the performance results described in Table 1. We seek to accelerate new ideas and approaches by leveraging Reclamation labs to validate key performance criteria and identify solutions that will be cost-effective for the farmers and communities.
Help us harness the power of innovation to ensure reliable water delivery to farmers and rural communities for the next 100 years. Let’s Water America’s Crops!

Following the end of Phase 2, each finalist will receive a data report including all laboratory tests conducted by Reclamation in Phase 2 and the performance results of their prototype for each test.
After the end of Phase 2, Reclamation intends to hold a showcase event where the finalists will have an opportunity to present to Reclamation customers and communities. Elements of the showcase event may be recorded and broadcast online and/or made available to irrigation districts and other Reclamation stakeholders after the event. The showcase event may be held in conjunction with Reclamation’s annual “Water Management Workshop,” in February/March 2023.
Over the long term, Reclamation is seeking partners to demonstrate and conduct field testing in communities that Reclamation serves.
Intellectual Property Rights
It is the Bureau of Reclamation’s preference that innovators commercialize their own technology and make it available to the Bureau of Reclamation through a commercial contract, or other terms. Nonetheless, the government also seeks a license to intellectual property contained within the winning submissions. These licenses ensure the government has access to further develop the technologies if they are not further developed by the innovators themselves.
Innovators who are awarded a prize for their submission must agree to grant the US Government a royalty-free license to use their submission. The terms of this license are available in the Challenge-Specific Agreement.

Additional Information
By participating in the challenge, each competitor agrees to submit only their original idea. Any indication of "copying" amongst competitors is grounds for disqualification.
All applications will go through a process of due diligence; any application found to be misrepresentative, plagiarized, or sharing an idea that is not their own will be automatically disqualified.
All ineligible applicants will be automatically removed from the competition with no recourse or reimbursement.
No purchase or payment of any kind is necessary to enter or win the competition.
Legal Agreement: We have updated the legal agreement for the Water America's Crops Challenge. You will be prompted to reaccept this agreement next time you return to the challenge page.
What's changed? We have added a clause regarding federal funding, federal facilities, and consulting with federal employees.
no Federal facilities or funds were used and innovator did not consult with Federal employees during the competition unless the facilities, funds and/or employees were made available to all individuals and entities participating in the competition on an equitable basis
Cost Calculation: We have simplified the requirement for calculating the cost of materials based on feedback from competitors. We are now asking for a cost estimate for materials required to build/manufacture the solution per square foot of canal.
Why the change? The initial request was for a cost estimate per length of the canal. Since the width and depth of canals is not standard, we've simplified the request to cost per square foot only.
Have you thought about forming a team to compete in the Water America's Crops Challenge?
Teams can be formed directly on the challenge page by connecting in the forum.
Some of the advantages of forming a team include:
1. Accountability
Those deadlines are less likely to get away from you when you’re working with a group.
2. Shared workload
You know the old “divide and conquer?” It works well for challenges! By finding a solid collaborative stride, a group of just three people can churn out a lot more than one person working alone.
3. Camaraderie
It might be hard for other people to relate to your lone wolf journey toward incentive competition conquest, but your team will be right there with you! A source of inspiration, motivation, and perhaps even fire-under-your-butt lighting, teammates can provide a huge emotional advantage. Just think - new internet friends!
4. Specialization
Maybe you’re a real visionary with an incredible concept, but are stuck on how the “nuts and bolts” fit together? Yeah, YOU need a team. Teammates who have the skills and special working knowledge can be a huge resource. And the benefits go both ways!
Rome wasn’t built in a day. Your team will take some time to come together, so be sure to get ahead of it and start recruiting, reaching out, and networking about the challenge now. The forum is a great place to start. Also, feel free to browse the entire HeroX Community by specialization by checking out https://herox.com/crowdsourcing-community.
