Capital Program Planning for Florida Water Utilities

by | Oct 21, 2026

Florida · Water & Wastewater Utilities

Florida is adding a city a year. Your capital plan has to keep pace with the water table.

The fastest-growing state in the country is also the most exposed — saltwater creeping into the Biscayne aquifer, two million septic tanks feeding red tide, and a coastline planning around feet of sea-level rise. Every one of those forces reshuffles the projects on your list. Invizion helps Florida utilities re-sequence a capital portfolio in a click — and defend every decision.

The bottom line: Florida is the fastest-growing state in the country, and its water is uniquely exposed — a shallow, saltwater-threatened aquifer, two million septic tanks feeding red tide, and a coastline planning around feet of sea-level rise. With a $26.75 billion drinking-water need and a generation's worth of SRF, WIFIA, and PFAS funding arriving at once, the utilities that win the decade will be the ones whose capital plans can absorb that volatility and stay defensible.

The Florida Landscape

Four forces are moving your project list at once

None of these is theoretical, and none of them waits for your next budget cycle. Together they mean the capital plan you approved last year may already be the wrong plan.

Demand — Growth

The fastest-growing state in the country

Florida added 467,347 residents between 2023 and 2024 — more than any state except Texas — and crossed 23.4 million people, growing about 2% in a single year.1

Every new rooftop is a service connection and a capacity commitment. Growth-driven capital competes for the same dollars as renewal and compliance, and the sequencing between them is exactly what boards and rate cases fight over.

Supply — Saltwater Intrusion

The aquifer is shallow, coastal, and under pressure

About 4 million people draw drinking water from the Biscayne aquifer, a shallow formation that underlies roughly 4,000 square miles of Broward and Miami-Dade — and its coastal edge is vulnerable to saltwater intrusion.3

The Floridan aquifer supplies most of the rest of the state; in Jacksonville roughly 90% of drinking water comes from groundwater. As sea level rises and pumping continues, utilities have relocated wellfields inland — a costly, capital-intensive fix — and the question of where the next gallon comes from is now a capital question, not just a resource one.5

Quality — Nutrients & Septic

Two million septic tanks, and the blooms they feed

Florida has more than 2 million septic systems — one of the highest counts in the nation — and most were never designed to remove the nitrogen that fuels algae blooms and red tide.6

The state has responded with money: nearly $390 million awarded to the greater Indian River Lagoon region since 2019, plus hundreds of millions more in recent water-quality and septic-to-sewer grants.7 Converting septic to sewer is one of the largest discretionary capital programs many Florida utilities will ever run — and it stacks on top of everything else.

Compliance — Resilience & Renewal

Planning around sea-level rise, on the same clock as renewal

Southeast Florida's regionally unified projection puts sea-level rise at 10 to 17 inches by 2040 and 21 to 54 inches by 2070 above the 2000 baseline — the number that coastal treatment plants, pump stations, and outfalls now have to be designed against.8

Resilience does not replace the renewal backlog. Florida carries a $26.75 billion 20-year drinking-water need and an estimated 1.16 million lead service lines — the most of any state.2 New obligations stack on the old backlog, and something on the list has to move.

Who Runs Florida's Water

Large municipal and regional systems, plus a long tail of private and small systems

Florida's biggest metros run their own water and wastewater utilities, and regional wholesalers like Tampa Bay Water supply several members at once. Alongside them sits a long tail of investor-owned utilities and small systems — the ones the Public Service Commission rate-regulates and where funding gaps hit hardest.

Municipal & regional systems

Rates set by city / county commissions · capital approved by governing boards

Miami-Dade Water & Sewer (WASD) ~2.4M residents served · 400,000+ retail accounts9
JEA (Jacksonville) 1M+ NE Florida residents · >$4B capital plan10
Tampa Bay Water Wholesale to ~2.6M people · 6 member governments11
OUC — Orlando Utilities Commission 240,000+ customers · 7 water plants12
Broward County Water & Wastewater Large county system on the Biscayne aquifer
Orange County Utilities Fast-growing Central Florida provider

Investor-owned & special-purpose systems

Rates & capital recovery regulated by the PSC

PSC-regulated investor-owned utilities 149 water and/or wastewater IOUs under FPSC jurisdiction13
Florida Governmental Utility Authority (FGUA) Special-purpose authority operating systems across multiple counties14
Numerous small & rural systems Where funding gaps and PFAS costs hit hardest

The FPSC does not set rates for municipal or county systems — those are approved locally — but it regulates the rates and capital recovery of Florida's investor-owned water and wastewater utilities.13

Rate-Setting & Oversight

Every capital dollar has to be defensible

Whether you answer to the Public Service Commission or a city commission, the question is the same: why this project, why now, why at this cost? Florida's oversight bodies and consent decrees are asking it harder than ever.

  • Florida Public Service Commission (PSC) regulates rates and capital recovery for investor-owned water and wastewater utilities — 149 systems as of 2022. Municipal and county systems set rates through their own commissions.13
  • FDEP holds Safe Drinking Water Act primacy — lead service line inventories (Florida has the most estimated lines in the nation), PFAS monitoring, and the compliance capital that follows.216
  • Consent decrees & ocean-outfall rules drive mandated spend — Miami-Dade WASD is executing a roughly $1.6 billion federal Consent Decree over 15 years on top of its broader capital program.9
  • City & county commissions approve municipal capital plans in public, in front of ratepayers — where growth, resilience, and affordability collide.

Funding On The Table

The money is moving — can your plan absorb it?

Florida utilities have more capital funding available than they've had in a generation, from state SRF loans to WIFIA and dedicated PFAS dollars. The constraint is no longer only dollars — it's readiness: which projects are shovel-ready, which qualify, and how the timing lines up with everything else on the list.

  • FDEP administers the Clean Water & Drinking Water State Revolving Funds. Year-one Bipartisan Infrastructure Law allotments to Florida included $70.6M for the Drinking Water SRF, $60.5M for the Clean Water SRF, and $111.3M dedicated to lead service line replacement.15
  • $537M+ in federal BIL water funding has been directed to Florida since 2022, including a 2024 round of over $361M through the SRFs — roughly half available as principal forgiveness for disadvantaged communities.4
  • WIFIA has invited about $689M in low-cost federal loans across five Florida projects in a single round — including $404M for Miami-Dade wastewater and $132M for Sarasota County.17
  • Dedicated PFAS & emerging-contaminant grants — Florida received about $52.6M in 2023, part of $87.55M in BIL emerging-contaminant funding announced for the state.16
  • State water-quality dollars — nearly $390M awarded to the greater Indian River Lagoon region since 2019, plus hundreds of millions more in recent statewide water-quality and septic-to-sewer grants.7

Where Invizion Fits

Turn a moving Florida picture into a defensible capital plan

Invizion is scenario-based capital portfolio optimization built for water utilities. When the supply picture shifts, a mandate lands, or a grant comes through, you don't re-plan by hand for weeks — you model it and decide with a record you can stand behind.

1

Model the “what-if” before it's forced on you

A new mandate, a failed main, a grant with a deadline — build the scenario and see the impact on the whole portfolio, side by side with today's plan.

2

Re-sequence 500 projects in a click

When priorities move, Invizion re-orders the portfolio automatically — accelerating, stretching, or deferring projects against the constraints you set, not weeks of spreadsheet surgery.

3

Give regulators or your board a defensible record

Every prioritization and trade-off is captured. When you're asked “why this project, why now,” the answer is documented — not reconstructed after the fact.

Florida Water, In Brief

Questions Florida utility leaders are asking

Short, sourced answers — the same facts we'll dig into on a call, in the context of your system.

Can a state with this much rain really face a water-supply problem?
Yes — the constraint is quality and access, not rainfall. About 4 million people rely on the shallow, coastal Biscayne aquifer, which is vulnerable to saltwater intrusion, and most of the rest of the state depends on the Floridan aquifer. As sea level rises and demand climbs with population, utilities have relocated wellfields inland and invested in alternative supplies — all capital-intensive.35
How big is Florida's water infrastructure need?
EPA's most recent Drinking Water Infrastructure Needs Survey puts Florida's 20-year drinking-water need at $26.75 billion — the fourth-largest of any state — and estimates roughly 1.16 million lead service lines statewide, the most in the nation. That is before wastewater, stormwater, and resilience spending.2
Why is septic-to-sewer such a big deal for Florida utilities?
Florida has more than 2 million septic systems, most of which don't remove the nitrogen that drives algae blooms and red tide. Converting them to central sewer is one of the largest discretionary capital programs many utilities will run. The state has committed real money — nearly $390 million to the Indian River Lagoon region since 2019 and hundreds of millions more in water-quality grants — but conversions still compete with renewal and growth for the same dollars.67
Who sets my utility's water rates in Florida?
The Florida Public Service Commission regulates rates and capital recovery for investor-owned water and wastewater utilities — 149 systems as of 2022. Municipal and county systems such as Miami-Dade, JEA, and Orlando's OUC set rates through their own governing commissions. Either way, capital spending has to be justified to a governing body and, increasingly, to ratepayers.13
What funding is available for Florida water utilities right now?
Florida's SRFs (administered by FDEP) received year-one BIL allotments of $70.6M for drinking water, $60.5M for clean water, and $111.3M for lead lines, and more than $537M in total BIL water funding has flowed to the state since 2022. WIFIA has invited about $689M in low-cost loans across five Florida projects, and dedicated PFAS grants add tens of millions more. The bottleneck is readiness — which projects qualify, and how the timing fits the rest of the plan.15417
How does Invizion help Florida water utilities plan capital?
Invizion is scenario-based capital portfolio optimization for water utilities. It lets you model how a saltwater-intrusion response, a septic-to-sewer mandate, a resilience deadline, or a funding award reshuffles your whole project list, re-sequence the portfolio automatically against your constraints, and keep a defensible record of every decision for the PSC, your commission, or ratepayers. The best next step is a short first meeting to look at it against your own program.
