A water system fails on its own schedule. Funding programs run on theirs. Interim financing exists in the space between the two.

The plain definition

Interim financing is short term money that lets a project begin before the permanent funding arrives. You borrow against an award you have been granted but not yet received, do the work, and repay the interim loan when the award pays out.

It is sometimes called bridge or gap financing. The mechanics are the same: the award is real, the cash is not there yet, and waiting has a cost.

Why the gap exists at all

Large programs are deliberate. A State Revolving Fund loan or a USDA Rural Development award involves environmental review, engineering review, procurement rules, and a closing process. That care is appropriate for spending public money at scale. It also means months, sometimes years, between “you are approved” and “the money is available to spend.”

Meanwhile the failure that started the project keeps costing you.

Felsenthal, Arkansas shows what that looks like. In November 2025, days before duck season transformed the town of 56 residents into a regional hub, two pumps at a lift station failed and could not be repaired. The deeper cause was a collapsed sewer main beneath the road that had let gravel and debris into the system. Sewage backed up into homes and spilled into the streets, and half the town lost sewer service.

To keep operating, the town hired crews to truck raw sewage from the disabled lift station to the treatment pond. It worked. It was also expensive and unsustainable, which is the character of every stopgap a system runs while waiting for funding.

Felsenthal’s repairs were ultimately paid for with state emergency funding through the Arkansas Natural Resources Division, secured with CU management specialist Cherub Alford working alongside the town on the funding source, the documentation, the applications, and the state’s online portal.

“I had no clue what to do. Cherub held our hand through it all.”
Theresa Howard, Mayor of Felsenthal

The initial emergency request, submitted in early December, was approved within days for up to $100,000, and the town eventually secured $151,224 in total. Fast, in that case. Read Breaking Point for the full account.

Not every situation resolves that quickly, and that is the point. When it does not, the cost of waiting is measured in hauling contracts, emergency repairs, and regulatory exposure.

When interim financing is the right tool

It fits when:

• You have a committed award and a documented timeline for when it pays out.
• Beginning work sooner materially reduces cost or risk, through avoided emergency spending, avoided penalties, or beating a construction price increase.
• Your system can carry the interim payment during the gap.

It does not fit when the award is not yet committed. Borrowing against a hoped for grant is a different and much riskier proposition, and a responsible lender will say so.

What it costs, and how to think about the cost

Interim financing is not free, and the honest comparison is not against zero. It is against the cost of waiting.

Put real numbers on both sides. On one side, interest and fees over the expected gap. On the other, whatever the stopgap is costing per month, plus any penalty exposure, plus the amount construction prices are expected to move. In an active failure, the waiting side is often the larger number.

For Communities Unlimited financing, that means lending up to $750,000, terms up to 15 years, and a 1 percent origination fee. Full details are on the water system loans page.

What to have ready

• The award letter or commitment, with expected disbursement timing.
• Your engineer’s scope and cost estimate.
• Recent audited financials. If your audits are behind, this becomes the first task rather than the loan.
• A current rate study, or willingness to run one.
• Board authority to borrow.

Common questions about interim financing

What is the difference between interim financing and a construction loan?

Interim financing is repaid from an award you are waiting on, so the repayment source is already identified. A construction loan is repaid from system revenues over a longer term. A single project can use both, with interim financing covering the period before the award disburses.

Can you get interim financing before a grant is awarded?

No. Interim financing is borrowed against a committed award with a documented disbursement timeline. Borrowing against an application that has not been approved is a different and much riskier proposition, and a responsible lender will tell you so.

The practical takeaway

Interim financing is not a way to fund a project you cannot afford. It is a way to stop paying the cost of delay on a project you have already won.

Communities Unlimited works alongside rural water and wastewater systems in Arkansas, Oklahoma, Tennessee, Louisiana, Mississippi, Texas, and Alabama, and can look at interim financing as part of your whole funding package rather than in isolation.
