For small water & wastewater utilities

Run your utility's finances in real time.

Budget, capital plan, and rate study — one synchronized model, updated every month, not every five years. So you always know where your utility stands, and where it's headed.

Built in collaboration with industry veterans — 30+ years inside the work. Currently in pilot.

What it does

Run the budget. Plan the capital. Set the rates.

Most small utilities operate blind between rate studies — and run the budget on spreadsheets. Flowcast replaces both with a structured workflow that keeps the financial decisions visible all year long.

Operating budget

Track your annual budget against monthly actuals. Spot variances when there's still time to do something about them — not at year-end. Plus water-loss and I&I monitoring calibrated to your state's regulatory threshold.

Capital plan

Tank rehabs, line extensions, treatment upgrades. Model SRF, USDA, and revenue-bond financing — and watch your DSCR against the tightest covenant, not a blended average. A 1.10× SRF loan and a 1.25× revenue bond means you have to hit 1.25× to stay in compliance. Flowcast tracks the binding number.

See who it's for

Rate study & affordability

Cost-based rates that work backwards from what it costs to run your system — fixed costs through the customer fee, variable costs through the volumetric rate. Defend the increase with line items, not “what felt reasonable.”

Why this, not the next thing

Built from inside the work.

Flowcast was shaped alongside a source-water specialist at the Tennessee Association of Utility Districts — a former water-utility manager whose career has been inside small public water systems.

The cadence, the thresholds, the board-report format all come from people who run them, not from accounting software adapted to fit.

Who it's for

Small utilities running on too many spreadsheets and not enough finance staff.

No more parallel spreadsheets emailed at midnight. No more rate study that drifts from the budget by Q2. One model, owned by you.

Utility managers

Rate studies every five years. A budget spreadsheet from your predecessor. A board that wants answers in between. Flowcast is the model that lives in between — entered once, updated monthly, ready when the board asks.

Volunteer boards · USDA covenants

Rural water and sewer associations

Politically difficult rate decisions. The board report is your primary communication vehicle — we treat it that way.

Multi-utility practitioners

Rate consultants & engineering firms

Stop rebuilding a spreadsheet for every client. Manage multiple utilities, snapshot state at engagement start, and turn the board report into your rate-study deliverable.

Built for the financial decisions, not the accounting.

Flowcast sits next to your accounting software, not in place of it. It's for rate-setting, budgeting, capital planning, and board reporting — the decisions a utility manager actually makes.

Walk into the public hearing with the math behind every dollar.

Test tier structures, see the bill impact at every usage level, and produce a rate recommendation tied to every line item in the budget. The rate study stops being the hardest part of the year.

How it works

From sample utility to your first board report.

Currently in pilot. Designed so you can get from sample data to your own numbers in an afternoon — not a quarterly project.

01

Start with Town of Example

Explore a complete model end-to-end — budget, capital plan, rate study, board report — before touching your own numbers.

02

Swap in your data

Chart of accounts, fixed-vs-variable cost split, existing debt with each covenant, capital plan. The structure walks you through what each field means.

03

Run the cycle

Update actuals monthly. When the budget changes, the rate study and the capital plan follow. The board report is assembled when you need it — not a deliverable to chase.

Common questions

Things people ask before signing up.

Is this an accounting system?+

No. Flowcast is for the financial decisions a utility manager makes — rate-setting, budgeting, capital planning, board reporting. It sits next to your accounting software, not in place of it.

Does it work for utilities that buy water rather than treat it?+

Yes. Treatment costs can be zeroed out. Setup handles distribution-only systems, treatment systems, and combined water + wastewater.

How does pricing work?+

Flowcast is in pilot. Pricing is in the low four figures per year — final tiers are being set with early customers. Request access for a conversation about what fits your system.

Where does my data live?+

In your account, with cloud sync across browsers and full export to JSON. Nothing is locked in. You can take your data with you at any time.

Why is the pilot in Tennessee?+

Flowcast was shaped alongside a source-water specialist at the Tennessee Association of Utility Districts — a former water-utility manager. So the rate-study cadence, the regulatory thresholds (Tennessee's 40% non-revenue-water ceiling included), and the board-report format all come from someone who lives the work. It's calibrated for Tennessee first because that's where it was built. Other states are next on the roadmap.

Built for the utilities other software wasn't built for.
