WaterSMART: Desalination Construction Projects (R26AS00034)

At a glance

What this opportunity is and what it funds

This is a water security and drought resilience funding line, not a pure research grant. The official NOFO language describes it as an invitation for eligible public entities to submit proposals for the planning, design, and/or construction of desalination facilities that use seawater, brackish surface water, or brackish groundwater. The funding is meant to widen local water supply options for growing communities and create additional operational flexibility when water availability becomes constrained.

The practical implication is important: this opportunity supports infrastructure, not theory. Reviewers are not looking for broad climate statements or general water policy essays. They are looking for projects that can reasonably move from proposal through implementation planning and into a build-ready or in-construction path for a defined facility, corridor, or treatment element. If your project is about building institutional capacity, outreach, education, or software-only innovation without a concrete plant or system component, this likely is not the right match.

The program sits inside WaterSMART’s larger effort to reduce regional water and energy stress. The opportunity description explicitly references drought adaptation and water supply diversification. That gives a concrete lens for proposal design: funding is strongest when the application can show the project is part of a real operational strategy, not a speculative idea.

Who this funding is for

The listed eligible applicants are all public and public-utility-style entities, including:

• States, departments of a state, and state subdivisions
• Tribes and tribal entities
• Municipalities
• Irrigation districts and water districts
• Wastewater districts

The same page also clarifies that applicants must be located in the listed eligible states.

This should be read as a program primarily for institutions that can carry permitting, design contract, procurement, and public works coordination. If your entity can point to a real project owner structure, in-house project staff, and statutory authority to enter construction agreements, you are likely a better fit than a startup without formal public utility governance.

Also important: institutes of higher education are explicitly listed as ineligible under this NOFO. Even if your university is a technical partner, they should support the proposal rather than lead it. Federal entities are also listed as ineligible as prime applicants.

The opportunity has a wide relevance profile. Public agencies in each listed basin and state can potentially use the funding for pilot-to-deployment scale desalination steps, including source capture planning, treatment train design studies, and construction planning packages that are strong enough to pass federal review.

Eligibility and fit requirements you should check early

Before drafting anything, confirm these criteria against your applicant profile and project scope:

1. Applicant type: Must be a qualifying public or quasi-public body (for example state agency, municipality, irrigation or water district, wastewater district, or tribe).
2. State list: Your governing entity must sit in one of the 16 eligible states.
3. Project type alignment: The work must be tied to planning/design/construction of desalination facilities using the eligible water source categories.
4. Entity eligibility: Federal entities and higher education institutions as prime applicants are not eligible.
5. Match requirement: The source listing marks cost sharing/matching as required, so applicants should budget and document non-federal contributions.
6. Submission rounds: There are two submission periods; teams can apply in the first round and continue to the second depending on timing and comments.
7. Application system: Applications are submitted through Grants.gov, so your grantor profile and registration status must be current before document preparation.

If your team clears all of these, the rest is largely application quality, not structural eligibility.

Timeline and deadline design (2026–2027)

The official listing states:

• Round 1 due date: August 26, 2026 at 4:00 PM MDT
• Round 2 (final): August 26, 2027 at 4:00 PM MDT

The listing also notes that applications received after round 1 close and before round 2 close are considered in the second submission period. This matters because it suggests the process expects staggered cycles with potentially different quality mix and maybe adjusted internal guidance between rounds.

Why this matters for planning:

• In the first six to eight weeks before Round 1, invest in a realistic scope that matches the deadline.
• Use public technical comments, past funding history, and internal pre-scoping to strengthen the submission before finalizing the budget and attachments.
• For teams that need pre-award design support, permitting consultation, or partner alignment, Round 1 may still be too aggressive.

Do not treat the second deadline as a “safe fallback” if your project has not been developed. Round 2 applications should remain robust, with all required compliance and partner confirmations in place, rather than an unrefined draft.

Award structure, budget logic, and what “cost share: yes” implies

The listing shows a program funding total of $120,000,000, 10 expected awards, award minimum $1,000, and a maximum of $120,000,000.

Those numbers look unusual in one line because minimum and maximum are broad. The practical interpretation is that this is a broad-scoped infrastructure funding line where project size varies widely across contexts. A tiny feasibility-focused design-only submission may be possible, while a larger build-scale proposal may be much bigger.

But the matching-cost-sharing requirement is the key financial signal:

• Budget your project so that non-federal contributions are explicit, realistic, and contractually plausible.
• If your match is only assumed and not documented, reviewers and award officers will question readiness.
• Show the match source as specific as possible (local capital match, district resources, state allocations, in-kind services, etc.).
• Track cost items carefully across planning, design, and construction phases; avoid conflating soft costs with eligible project costs.

Because this is a cooperative agreement funding type, the federal partner may expect a more collaborative implementation posture than a standard grant with minimal administration after award. In practice, that means stronger technical reporting, project tracking, and integration with program milestones.

What a strong proposal usually includes

Use this structure to align directly with what the program appears designed to fund:

1) Clear water-system problem statement

Do not start with “our region faces drought.” Start with a measured deficit and a technical requirement that water treatment planning cannot meet through current capacity. Quantify baseline demand, projected demand changes, and water-source variability where possible.

2) Project definition tied to treatment method

Specify whether the proposed project is

• seawater reverse osmosis planning/design,
• brackish source assessment to design,
• or brackish groundwater treatment pathway,
• and why that path is selected.

Include the full system-level logic: source characterization, pretreatment assumptions, energy demand, disposal pathways, and reliability impacts.

3) Delivery and construction readiness

Because this is explicitly planning/design/construction, include schedule and sequencing with real dependencies:

• engineering data collection,
• permitting path,
• procurement and contract strategy,
• construction phasing,
• operations planning.

If these dependencies are missing, the application sounds like a concept, not a funded infrastructure program.

4) Match, governance, and partner commitments

A public-water partner often relies on partner agencies, legal teams, and technical engineering firms. Make these relationships explicit in writing:

• Which agency signs off on design authority,
• which entity owns permitting responsibility,
• which party provides project match,
• and which body commits to long-term operations post-construction.

5) Outcome metrics tied to supply resilience

Use measurable outcomes such as:

• incremental local supply flexibility,
• additional source diversity,
• peak period vulnerability reduction,
• construction milestones achieved by agreed dates,
• and compliance deliverables that align with federal expectations.

Application preparation checklist for 2026–2027 submission

The official listing points teams to Grants.gov for submission and references supporting NOFO documents via attachments. Use this preparation sequence:

1. Build a one-page project brief that states problem, solution, timeline, and readiness.
2. Confirm your entity is eligible and in an approved state.
3. Prepare a full cost share plan before writing technical scope.
4. Align engineering partners and legal counsel with project ownership.
5. Draft a deliverables plan in three tracks:
   • technical design track,
   • fiscal/matching track,
   • permitting/compliance track.
6. Convert technical assumptions to plain language for reviewers and public records.
7. Prepare attachments in the format required by Grants.gov and the NOFO packet.
8. Build a submission calendar with internal sign-off gates at T-30, T-14, and T-5 days.

Applicants often fail here not because of weak technical merit, but because they underestimate administrative coordination for multi-agency projects.

Common mistakes that reduce competitiveness

1) Submitting a non-eligible structure

Federal applicants, universities as prime, or entities outside the eligible states are not allowed. This is disqualifying.

2) Weak match logic

The listing marks matching as required. If the non-federal contribution is vague (“funding to be determined”), the application looks speculative.

3) Overly broad project narrative

Proposals that sound like a broad climate program without a concrete desalination system path usually underperform in technical screening.

4) Misreading the deadline windows

Round 1 and Round 2 are distinct windows. Teams must either plan for first-round readiness or fully rebuild for the second window.

5) Insufficiently funded execution design

A high-level plan for a plant is not enough. Reviewers expect enough design and construction detail to show project credibility.

6) Missing inter-jurisdiction coordination

When a district, municipality, state agency, and tribal body collaborate, coordination failures can derail feasibility. Include a signed governance map and roles.

Why this can be a good fit for your institution (or not)

This opportunity is especially strong if you meet all of these conditions:

• You are a direct public water-serving applicant in one of the listed states.
• You already have or can secure cost-share commitments.
• You have technical capacity for engineering scope and permitting strategy.
• You need a public funding partner to move from design to construction.

It is a weaker fit if your team is early-stage research-only, lacks public authority to execute construction, or relies solely on uncertain private funding for match.

A practical way to decide fit is to test a simple question:

Can this team deliver a real desalination project component before the first eligible deadline?

If the answer is no, Round 1 should be avoided unless the scope is intentionally reduced.

Geographic and policy context

The eligible geography list concentrates in states facing recurring drought, high inter-basin competition, or strong agricultural and industrial water demand pressure. This is a design signal: proposals should reflect local operational conditions, not generic national assumptions.

The WaterSMART portal frames desalination within a broader program of water recycling, reservoir and watershed resilience, and hydropower-related planning. Teams should mention how their proposal complements, rather than duplicates, adjacent projects in their basin.

From a policy perspective, this program supports U.S. water reliability goals and does not appear limited to a single sector. Community water systems, regional utilities, industrial users, and agricultural districts can all potentially fit as long as they show public benefit and clear implementation pathway.

Frequently asked questions

Is this program still open for applications?

Yes, based on the listing and status notes available at the time of this scan, two submission periods are active: 2026-08-26 and 2027-08-26.

Is matching funds mandatory?

Yes, the listing marks cost sharing or matching as required.

Can universities apply as lead?

No. Ineligible applicant examples include institutes of higher education as lead applicants.

What are the expected award sizes?

The official listing shows an award minimum of $1,000 and a maximum of $120,000,000, with total program funding of $120,000,000.

Who should prepare the matching documentation?

The lead public entity should own the financial structure and provide clear documentation for non-federal contributions. External partners should provide confirmable letters/cost commitment where possible.

Where should I submit?

Applications are submitted through Grants.gov. The WaterSMART program page and this NOFO listing provide the official context and status.

Is there an eligibility requirement for municipalities only, or also water districts?

Water districts and wastewater districts are eligible applicant types on the listing.

How to prepare your next step now

If your project is within scope, the next action is not to write a 40-page narrative and then discover it was filed from the wrong organizational structure. Instead:

1. Confirm your applicant category and state.
2. Lock the lead and implementing entities.
3. Prepare a first-pass match plan.
4. Build a technical concept in the exact language of planning, design, and construction.
5. Submit before internal bottlenecks accumulate.

This is not a grant for exploratory studies with no follow-through. It is an infrastructure program built for teams that can progress toward tangible supply outcomes. If your planning group already has enough groundwork done, this call can be one of the strongest U.S. public-water opportunities available in the 2026/2027 cycle.
