The Bureau of Reclamation is seeking innovative solutions to expand usable water supplies by maximizing fresh water production from inland desalination systems in a cost effective and environmentally sound manner. Currently, significant and desirable water supplies are trapped in concentrate streams that are a byproduct of desalination technologies. The cost to manage or dispose of concentrate is rather large and very limiting to utilization of desalination in inland applications. Solutions can be novel technologies or approaches that build upon existing technologies. Solutions should address one of the following objectives, 1) ways to improve overall system recovery of existing desalination technologies, 2) ways to treat concentrate streams to extract additional useable water and thus to increase overall system recovery, or 3) new high recovery desalination technologies or processes that increase overall system recovery beyond current desalination technologies.
This Challenge launches Stage 1 of a planned three-stage Grand Challenge that culminates in a technology demonstration within a field-test setting.

In many areas, particularly in the Western United States, existing sources of fresh water are fully or over-allocated. When inland communities are evaluating potential sources for a new water supply, desalination is often overlooked or not considered due to its perceived high cost. A major contributing factor to the cost is the additional handling and/or treatment required to manage concentrate streams where significant and desirable additional water resources are also lost.
Desalination processes, typically membrane or thermal based processes, produce a concentrate stream composed primarily of the salts in the feed and some of the initial feed water. The cost to manage or dispose of concentrate streams is often prohibitive for inland brackish desalination and is currently a limiting factor to more widespread utilization of desalination in inland applications. This challenge is seeking solutions to minimizing the concentrate stream volume and associated handling costs while maximizing the useable water produced by the process.
Desalination process recovery is often limited by capital and operational treatment costs. Saturation levels of sparingly soluble species (e.g. CaSO4, CaCO3, SiO2) are reached in desalination processes as the saltwater feed is processed to fresh water leaving behind a highly saturated stream referred to as concentrate. Thus, classes of solutions to the concentrate problem might increase the quantity of treated water recovered from desalination processes without incurring issues with sparingly soluble species, therefore decreasing the volume of concentrate generated and increasing the overall system recovery. Other solutions may include novel desalination technologies or improvements to existing technologies that will increase the overall system recovery of desalination processes while also overcoming other operational and cost hurdles.
Another class of solutions to the concentrate problem is to post-treat the concentrate stream that is produced to reduce its concentrate volume or to produce a solid waste product; thereby reducing the volume requiring disposal.
In this prize competition, the Bureau of Reclamation is seeking innovative solutions to increase the amount of usable water supplies in an affordable, environmentally sustainable, and efficient manner to make desalination more accessible to communities looking to expand water supplies. Solutions can be novel technologies or approaches that build upon existing technologies and approaches for the production of fresh water from saline sources that increase the overall system recovery beyond the level of what is currently achieved. Solutions can include ideas to reduce the large concentrate volumes by treatment of the concentrate or by selectively removing less soluble species from either the feed water, concentrate streams or at any other part of the desalination system. Other ideas to control or inhibit scale formation due to sparingly soluble species are also being sought along with any new technologies or improvements to existing technologies that increase the overall system recovery of a desalination system.

This Challenge consists of three stages:
In addition to the direct monetary award for Stages 2 and 3, Reclamation will invite industry, non-profit organizations, and venture capital representatives to be present at the Stage 2 and 3 presentations and testing. Participating industry and venture capital representatives will also have the ability to seek and secure potential business deals with Solvers.
This posting only launches the Stage 1 competition. However, the envisioned framework and prizes for Stages 2 and 3 are available here: https://www.usbr.gov/research/challenges/morewater.html. Subsequent stages will be officially launched and announced with a separate Challenge.gov posting and a separate Federal Register Notice.
Stage 1 is a Theoretical Challenge that requires only a written proposal to be submitted. The Challenge award will be contingent upon critical analysis and evaluation by the Seeker (Reclamation) and the judging panel appointed by the Seeker. The Seeker has a total prize pool budget of $150,000 to pay the top six submission(s) that meet or exceed the criteria below an award of at least $25,000 each. No awards are guaranteed unless they meet or exceed the criteria, and more than one award is not guaranteed. Full or partial awards will be considered for solutions that meet all or some of the criteria, respectively. If only a single submission meets or exceeds the criteria, the prize award may be as high as $50,000.
To receive an award, the Solvers will not have to transfer their IP rights to the Seeker and will not have to grant the Seekers a non-exclusive license to practice their solutions. Please note that any proposal submitted will not be treated as confidential information. Accordingly, Solvers should take whatever steps they deem necessary to protect their proprietary rights in their solutions prior to submitting their written proposal for consideration in the Challenge (e.g. filing provisional or full patent applications on the solution described in the written proposal submitted prior to submission). See the Challenge-Specific Agreement for full details.
Submission period ends on March 13, 2017: Submissions to this Challenge must be received by 11:59 PM (US Eastern Time) on March 13, 2017. Late submissions will not be considered.
After the Challenge submission deadline, a Judging Panel will evaluate the submissions and make a decision with regards to the winning solution(s). The Judging Panel may be composed of Federal and/or Non Federal scientists, engineers, and other technical experts, including subject matter experts from the listed collaborators for this Challenge. All persons or entities that submit a proposal will be notified on the status of their submissions. Decisions by the Seeker cannot be contested.
IMPORTANT ELIGIBILITY INFORMATION

Solvers are not required to give up any of their intellectual property (“IP”) rights to the Seeker or Seeker Collaborators to be eligible to receive an award. Solvers who have transferred their IP rights in their solution to another, or otherwise entered into any commercial exclusive arrangement with another for the exploitation of their IP rights in their solution prior to the end of the Challenge shall not be eligible for a Challenge award. See the Challenge-Specific Agreement for full details.

What is a Theoretical Challenge?
An InnoCentive Theoretical Challenge builds upon an idea but is not yet a proof of concept. A solution to a Theoretical Challenge will solidify the Solver's concept with detailed descriptions, specifications and requirements necessary to bringing a good idea closer to becoming an actual product or service. For details about treatment of IP rights, please see the Challenge-Specific Agreement.
