Houses and pipes in Evansville

The Riverside historic district, Haynie's Corner and the downtown edges have Victorian and Italianate homes from the 1850s through the 1910s, many with basements and clay laterals.

The near east side, Bayard Park, Jacobsville and the neighborhoods around the University of Evansville were built from the 1900s through the 1940s with bungalows, foursquares and cottages.

The north and east sides filled in after World War II with ranches on slabs, crawlspaces and basements.

Newer subdivisions toward the far east side and northern Vanderburgh County have PVC drains.

Much of the older city has combined sewers, and the Evansville Water and Sewer Utility is under a long-term plan to reduce overflows into the Ohio River and Pigeon Creek.

Who handles what in Evansville

The Evansville Water and Sewer Utility runs the city's sewer system and treatment plants. The private lateral from an Evansville home to the city sewer belongs to the owner, who handles its upkeep.

Evansville drains through the year

Spring storms and high water on the Ohio raise groundwater across the low parts of the city, and summer brings the fastest root growth.

Winters are milder than northern Indiana but still bring cold snaps that freeze drains in garages and crawlspaces.

What drain cleaning costs in Evansville

JobTypical range
Sink, tub or toilet cleared$120–$260

Root cutting$245–$565
Hydro jetting$320–$775
Sewer scope inspection$130–$265

Newer east side lines are quick. Old clay in Riverside, crawlspace access and lines in waterlogged ground near the river take longer.

Before the plumber arrives

  1. 1

    Pause the drains

    No laundry, dishwasher or showers for now.

  2. 2

    River up?

    When the Ohio is high and it's raining, low-lying sewers can back up.

  3. 3

    Check the lowest drain

    A basement floor drain or, in a crawlspace home, the bathtub usually shows it first.

  4. 4

    Find the cleanout

    Look on the front basement wall or outside by the foundation.

Riverside and Haynie's Corner

The Riverside historic district, along the Ohio River east of downtown, has grand Victorian, Italianate and Queen Anne homes built by river merchants and industrialists. Haynie's Corner, nearby, has smaller homes and an arts district. Clay laterals under those old trees are often original, and roots are the most common cause of backups.

Jacobsville and the north side

Jacobsville, north of downtown, grew up as a working-class neighborhood for factory workers, with cottages, shotgun houses and bungalows. Many have crawlspaces or partial basements. Old clay laterals and cast iron stacks, plus decades of rental use, make clogs common.

Bayard Park and the near east side

Bayard Park and the neighborhoods around the University of Evansville have bungalows, foursquares and Tudors from the 1910s through the 1940s on tree-lined streets. Big trees and clay laterals mean roots. Homes near the university include many student rentals.

Combined sewers and the river

Evansville's combined sewers overflow into the Ohio River and Pigeon Creek during heavy rain, and the city is working through a long-term plan to reduce those overflows. High river levels make the problem worse by slowing outflow. For homeowners in low neighborhoods, a backwater valve and disconnected downspouts help keep sewage out of the basement.

A typical Evansville call

In April, with the Ohio running high after a week of rain, a family in a 1920 bungalow near Bayard Park sees water coming up through the basement floor drain. The plumber opens the cleanout and clears roots about thirty-five feet out, then the camera shows groundwater seeping in through a cracked joint. They decide on a liner and a backwater valve.

Crawlspace homes

Many Evansville homes from the early and mid twentieth century sit on crawlspaces, with drain lines running under the floor. In the humid Ohio Valley, crawlspace moisture is high, and leaking drains add to it. A musty or sewer smell from under the house is a sign to have the lines checked.

Postwar east side

The east side grew after World War II with ranches and split-levels for families working at Whirlpool, Alcoa and other plants. Cast iron and clay laterals from that era are now aging, with scale and roots the usual findings.

Clay and river soils

Evansville sits on a mix of river silt and clay that holds water and settles over time. Laterals can sag into bellies where waste collects, causing recurring clogs. A camera inspection shows where the line has settled.

Restaurants and the riverfront

Downtown's restaurants near the riverfront and the casino, Franklin Street on the west side and the corridors along Green River Road and the Lloyd Expressway serve a lot of fried food, and Evansville's fish sandwich stands are famous. Kitchens in older buildings keep backups away by pumping interceptors and jetting lines regularly.

Franklin Street and the west side

The west side, along Franklin Street, has a strong neighborhood identity, with bungalows and cottages from the early 1900s and a busy commercial strip. Clay laterals and cast iron are common, and the West Side Nut Club Fall Festival each October brings huge crowds and heavy use to local restaurants.

Winter in the Ohio Valley

Evansville's winters are milder than northern Indiana's, but a few cold snaps each year drop into the teens or below. Crawlspace drains and pipes in unheated garages are first to freeze. Close crawlspace vents during cold spells and let a faucet trickle overnight.

Levees and the 1937 flood

The great Ohio River flood of January 1937 put much of Evansville under water, and the levee and floodwall system built afterward still protects the low neighborhoods near the river and Pigeon Creek. When the river rises behind those levees, gates close and storm water has to be pumped over the wall. During those stretches, local sewers in the protected areas drain more slowly, and a heavy local storm can back water into basements that stay dry the rest of the year. Homeowners in the old flood zone are the ones who benefit most from a backwater valve and a floor drain plug.

Before calling

Have your neighborhood, the home's approximate age and the foundation type ready. Mention whether it rained hard or the river was high, whether big trees grow near the lateral and whether it's a rental.

Evansville drain questions

Who handles sewer in Evansville?+

The Evansville Water and Sewer Utility runs the public sewers. Owners keep up the private lateral.

Why do Evansville basements flood when the river is high?+

High river levels raise groundwater and slow the flow from combined sewers, so heavy rain can push water back into low basements.

Are Riverside homes prone to root clogs?+

Yes. Clay laterals there are often more than a century old and run under large trees.

Is a camera inspection worth it when buying an older Evansville house?+

Yes, especially for homes built before 1960.
