Drainage in Pinellas County, Built for the Flattest, Most Crowded Ground in Florida

On a peninsula this low and this full, water has nowhere to go on its own. We give it a way out.

Pinellas is a narrow strip of land with the Gulf on one side and the bay on the other, packed tighter than any county in the state. From the barrier islands at tide level to the older streets of St. Petersburg to the sand-over-hardpan yards up north, the water sits where it lands. Trufam Drainage designs and builds the systems that move it off your property, in every corner of the county.

The Pinellas Drainage Picture

One small county, three different ways to hold water

Pinellas packs almost a million people onto a low, narrow peninsula, and the ground does not drain the same everywhere. The barrier islands and bay shores sit right at tide level over saturated sand. The older heart of St. Petersburg was laid out before modern drainage rules, so the pipe was never put in. And the north county sits on sand over a hard clay pan that stops water cold. We start every job by reading which of these you are standing on.

Pinellas County, Florida. We build drainage across all of it, from Oldsmar and Palm Harbor in the north to St. Petersburg and the beaches in the south.
The coast and barrier islands

Ground that sits at the tide line

The beaches, bay shores, and low pockets of south St. Petersburg sit only a few feet above the water. The sand under the grass is often already full, so an ordinary storm has nowhere to drain down to. The record surge that hit the Pinellas coast in 2024 showed just how little room there is here.

Cities hereClearwater, Seminole, and the beach towns
Dense, older mid-county

Neighborhoods built before drainage rules

Much of St. Petersburg, Largo, and Pinellas Park went up mid-century, before the county required storm water plans. The lots are small and packed close, with little grading and no pipe put in the ground. Add decades of new driveways and additions, and the water that used to spread out now has nowhere to sit but the yard.

The north-county flatwoods

Sand over a hard pan that will not drain

Palm Harbor, Dunedin, Safety Harbor, and Oldsmar sit on old flatwoods, sand over a tight clay hardpan with a seasonal water table close to the surface. Rain slips through the top foot fast, hits the pan, and stops, so yards stay soft for days after the sky clears.

County Permitting, In Plain English

Who permits drainage work in Pinellas

Pinellas is a patchwork of cities. St. Petersburg, Clearwater, Largo, Pinellas Park, Seminole, Dunedin, Safety Harbor, Oldsmar, and the rest each permit work inside their own limits, while unincorporated areas go through the county. The rules are not complicated, but they do change with your address. Here is the short version, and we handle the details for the work we do.

This is general guidance, not legal advice. We confirm exactly what your specific job needs before we start.

Gutters and routine yard drainage

New seamless gutters and downspouts, and ordinary yard drainage, are treated as everyday repairs and generally do not need a building permit in most Pinellas cities.

Connecting or moving drain lines

Altering, replacing, or relocating drainage piping can require a permit because it changes how storm water leaves the property. We pull one when the scope of your system calls for it.

Tying into a public line or the right-of-way

Connecting to a city or county storm structure, or working in the road right-of-way, needs a right-of-way permit. We keep the system on your property wherever the design allows.

New builds and major changes

New construction and substantial rework fall under the county storm water manual and need a drainage plan. We design to those standards so the water path holds up on paper and in the ground.

What We Build Across the County

Six systems, matched to the ground you have

We walk the property first, find where the water starts and stalls, and where it can legally go. Then we build only what your lot actually needs, with the same materials from Oldsmar to the beaches.

01

French Drains

Perforated pipe wrapped in DOT-grade fabric and clean #57 granite, custom-built for the water your soil traps. The fix for grass that stays soaked over sand, hardpan, or a high water table.

02

Underground Drainage

Solid SDR-35 pipe carries roof and surface water from every downspout and basin to a real discharge, well away from the slab, with serviceable cleanouts at the connections.

03

Yard Drainage

Catch basins, channel drains, and collection built for flat lots and dead swales. Designed around fences, pool cages, and the way your lot actually sheds water.

04

Foundation Drains and Waterproofing

A perimeter drain at the footing plus a rubberized wall membrane, built for the slab and stem-wall homes on the county's low, high-water-table ground.

05

Seamless Gutters

6-inch and 7-inch K-style gutters sized for Florida rain and tied into the underground system, so the roof stops feeding the puddle.

06

Drain Cleaning and Hydro Jetting

High-pressure cleaning for underground lines, channel and pool drains, basins, and outlets. Solid PVC jets safely and drains like new again.

The Trufam Standard

Built for the water Pinellas actually gets

Storms stall over the bay and drop several inches in an afternoon, and on ground this low and this crowded the yard has to carry its own water. The county and the cities are spending heavily on public storm water projects, but none of that public work drains a private lot. The yard is the homeowner's job, and it is what we build for, with materials chosen for decades in wet, salty, sandy ground and no shortcuts.

Solid SDR-35 pipe

Commercial-grade PVC in 20-foot sections. Fewer joints, no crushing, nothing for roots to find.

Clean #57 granite

Hard stone that keeps draining. We skip limestone, which breaks down in the ground.

DOT-grade fabric

Real drainage fabric rated for about 50 years in the ground. Weed barrier lasts a couple.

Serviceable access

Sediment basins and cleanouts at the connections, so the system can be maintained without digging.

Gravity first

Systems pitched to drain dry between storms. Pumps only where the low ground gives no fall.

Most Pinellas homeowners who call us have already paid once for a fix that did not last. A Trufam system is designed, priced, and built to be the last one the yard needs.

Pinellas Drainage Questions

Asked by Pinellas homeowners, answered straight

It depends on the work and your address. New gutters and ordinary yard drainage usually do not need a building permit. Connecting or relocating drain lines can, because it changes how storm water leaves your property, and tying into a city or county line or working in the road right-of-way needs a right-of-way permit. Each Pinellas city permits inside its own limits, and unincorporated areas go through the county. We tell you what your specific job requires and handle the permitting the work calls for.

All of them. We build across St. Petersburg, Clearwater, Largo, Pinellas Park, Seminole, Palm Harbor, Dunedin, Safety Harbor, and Oldsmar, plus the beach towns and unincorporated pockets in between. The materials and the standard are the same everywhere.

Much of the mid-county was built before the county required storm water plans, so the drainage pipe was simply never put in. The lots are small and sit close together, and every new driveway, addition, and pool over the decades has covered more of the ground that used to soak up rain. The water has to go somewhere, so it pools in the low yard. A yard drainage or underground drainage system gives it the path the neighborhood was never built with.

Yes, for the water you deal with most. On the barrier islands and low bay shores the sand is often already full, so an ordinary storm has nowhere to drain down to. A system built for that ground moves the everyday rain off your yard and out to the best discharge the lot allows, even where there is little fall to work with. No yard system stops a hurricane storm surge, and we will always be straight with you about that. What we fix is the standing water that shows up after a normal Florida afternoon.

The north county sits on old flatwoods, a foot or two of sand over a tight clay hardpan, with a seasonal water table close to the surface. Rain slips through the sand fast, hits the pan, and stops, so it spreads sideways instead of draining down. A French drain built for the way your ground actually layers pulls that trapped water out of the grass and carries it to a real outlet. Guesswork drains skip the pan and fail. Ours start with it.

Flood maps and flood insurance deal with storm surge and rising water. Water standing in the grass after an ordinary storm is a drainage problem, and drainage problems are fixable. A yard drainage system moves the everyday water out, which also means the ground is not already full when the big storms come.

The price follows the design: how much water, how far it has to travel, and what the discharge takes on a tight, low lot. We use commercial-grade materials and build systems meant to work for decades, so we are rarely the lowest bid. Most homeowners who call us have already paid for a cheap fix once. Every estimate starts with a walkthrough, and you see exactly what you are paying for in writing.
