Houses and pipes in Jacksonville
Riverside, Avondale, Springfield and San Marco hold some of the largest collections of historic homes in the Southeast, built from the 1890s through the 1930s. Many sit on raised foundations, with clay or cast iron laterals running under huge live oaks draped in moss.
After World War II, neighborhoods like Arlington, Lakewood, Ortega Forest and much of the Westside filled with concrete-block homes on slabs, usually with cast iron drains under the floor. Florida's cast iron has a reputation for rotting out from the inside, and many of those lines are now failing.
Mandarin, the Southside and the beaches grew through the 1970s and 1980s, and Nocatee, Bartram Park and the fast-growing areas along the St. Johns County line have been built since 2000 with PVC drains.
Jacksonville sits on sandy soil over a high water table. Laterals settle in the sand, groundwater seeps into cracked pipe, and heavy rain can overload mains.
Some older parts of the city were built on septic systems, and JEA has been converting neighborhoods to sewer for years.
Who handles what in Jacksonville
JEA, the city-owned utility, provides sewer service across most of Jacksonville and operates the treatment plants. The private service line from the house to the JEA main or cleanout at the property line is the owner's responsibility. Some neighborhoods still use septic tanks.
Drain problems Jacksonville homes see most
| Problem | Why it happens here |
|---|---|
| Rotting cast iron under slabs | Homes from the 1950s through the 1970s |
| Live oak roots | Riverside, Avondale and San Marco |
| Groundwater infiltration | High water table and sandy soil |
| Storm and tide backups | Hurricanes and nor'easters |
| Septic backups | Neighborhoods not yet converted |
| Grease and wipes | Busy family households |
Jacksonville drains through the year
Summer afternoon thunderstorms and hurricane season, June through November, bring heavy rain that can overload sewers. Nor'easters in fall push high tides up the St. Johns River.
Winters are mild, though rare hard freezes can burst exposed pipes. Thanksgiving fry-ups and holiday gatherings bring grease clogs.
What drain cleaning costs in Jacksonville
| Job | Typical range |
|---|---|
| Sink, tub or toilet cleared | $130–$275 |
| Main line cleared from a cleanout | $195–$440 |
| Root cutting | $265–$590 |
| Hydro jetting | $340–$800 |
| Camera inspection | $150–$390 |
| Cast iron descaling | $500–$1,200 |
Newer homes in Nocatee or Bartram Park are usually quick visits. Riverside laterals under oaks and failing cast iron under 1960s slabs take the most time, and under-slab repairs are quoted after a camera inspection.
Before the plumber arrives
- 1
Hold off on water
Pause the dishwasher, washer and showers.
- 2
Sewer or septic?
Some older neighborhoods are still on septic; check your JEA bill for a sewer charge.
- 3
Storm or tide?
During heavy rain or a nor'easter, mains may be full. Wait for the water to drain.
- 4
Find the cleanout
Often near the front wall or close to the property line by the sidewalk.
Riverside and Avondale
Riverside and Avondale, along the west bank of the St. Johns, have bungalows, Prairie-style homes and grand houses from the early 1900s under live oaks that are among the city's treasures. Laterals there are often original clay or cast iron, and oak roots find every crack. Many owners line their laterals to protect both the pipe and the trees. Restaurants along Park Street and King Street need regular grease trap service.
Springfield and San Marco
Springfield, just north of downtown, has Victorian homes being restored block by block, many tied into century-old laterals. San Marco, across the river, has 1920s Mediterranean-style homes with similar pipes. Scoping the lateral during a renovation is the smart move.
Cast iron under postwar slabs
Arlington, Lakewood and much of the Westside were built in the 1950s and 1960s with cast iron drains under concrete slabs. In Florida, that iron corrodes from the inside, and the bottom of the pipe can rot away entirely, letting water wash out the sand beneath the slab. Slow drains, sewer smells and soft spots in floors are warning signs. Lining and rerouting are common fixes.
Mandarin, the Southside and the beaches
Homes from the 1970s and 1980s in Mandarin and the Southside often have early PVC or a mix of materials. Big oaks planted then are now reaching laterals. At the beaches, salty air corrodes metal, and sand gets into drains from outdoor showers.
A typical Jacksonville call
In August, a family in a 1962 block home in Arlington notices the hall bath toilet gurgling and a sewer smell in the bedroom. The plumber clears the main from the front cleanout and runs a camera, which shows the cast iron under the slab has rotted along the bottom. The family gets quotes for lining versus a reroute through the attic.
Sandy soil and groundwater
Jacksonville's sandy soil drains well but settles over time, leaving bellies in laterals. The water table is high, so cracked pipe takes in groundwater, especially after storms. Sealing a lateral with a liner reduces infiltration and backups.
Hurricanes and nor'easters
Hurricane Irma in 2017 pushed record flooding up the St. Johns into downtown and San Marco. Nor'easters can also drive high tides into low neighborhoods. After a flood, silt and debris can stay in drains, and a jetting and camera inspection clear them.
Septic conversions
JEA has been replacing septic tanks with sewer in older neighborhoods for years. If your home was converted, the old tank should have been abandoned properly. If you're still on septic, pump it every few years and watch for wet spots over the drain field.
Military families
Naval Air Station Jacksonville and Naval Station Mayport bring many military families who rent and move often. Find the cleanout on move-in and report slow drains early.
What to tell a Jacksonville plumber
Give your neighborhood and the home's age, whether it's on a slab or raised foundation and whether you're on sewer or septic. Mention big oaks and whether the trouble started during a storm or high tide.

Jacksonville drain questions
Who handles sewer in Jacksonville?+
JEA provides sewer service for most of the city. The line from your house to the JEA connection is yours to maintain.
Why is cast iron failing in my 1960s house?+
Florida's warm, humid conditions and sewer gases corrode cast iron from the inside. Many lines from that era have cracked or rotted along the bottom. A camera inspection shows the condition.
The oak in my front yard sits right over the sewer. What are my options?+
Jacksonville protects many large oaks. Cutting roots inside the pipe or lining the lateral fixes the problem without excavating around the trunk.
Is my neighborhood on septic?+
Some older areas still are. JEA has been converting neighborhoods to sewer. Your bill will show a sewer charge if you're connected.
