Home to the Ravinia Festival
Highland Park hosts the Ravinia Festival, a major outdoor concert venue, and the surrounding neighborhoods share the North Shore's characteristic ravine topography and mature tree cover.
Large, historic homes here often carry cast-iron stacks and clay laterals from the early-to-mid 20th century, now dealing with fixture loads well beyond original design.
Ravine Terrain and Lake Michigan Bluffs
Properties near Highland Park's ravines and lakefront bluffs see drainage behavior shaped by that terrain, distinct from a flat inland lot.

Ravinia, Ravines and Lakefront Estates
Highland Park was incorporated in 1869 on the bluffs above Lake Michigan, formed from the settlements of St. Johns and Port Clinton, and it grew as an elegant commuter suburb on the Chicago and North Western line. Wealthy families built estates designed by leading architects, including several by Frank Lloyd Wright such as the Ward Willits House, often cited as one of the first Prairie School homes. The Ravinia Festival, which began as an amusement park in 1904 and became the summer home of the Chicago Symphony Orchestra, is one of the country's oldest outdoor music festivals. Fort Sheridan, a former Army post on the city's northern edge, has been redeveloped into a residential community.
Highland Park's housing ranges from grand lakefront estates and historic homes to early twentieth-century houses, mid-century ranches and split-levels, and newer construction on teardown lots. Plumbing varies from century-old systems to modern PVC.
Deep ravines cut through the city toward the lake, and the bluffs, lakefront and the Skokie River to the west all shape drainage.
Ravines and Bluffs
Many Highland Park homes sit near ravines or on bluffs, with laterals running down slopes or across uneven ground. Steep grades move water quickly but leave solids where the grade changes, and erosion can undermine buried pipe.
A camera inspection shows the grade and condition of a lateral and pinpoints problem spots. Lining is often a practical repair where excavation near ravines would be difficult.
Follow city guidelines for directing downspouts and sump discharge away from ravines and bluffs.
Historic Homes and Long Laterals
Highland Park's historic homes often sit on deep lots with long laterals passing mature trees. Root intrusion at multiple joints is common in century-old clay pipe.
A camera inspection with locating equipment maps where the lateral runs and where defects occur.
When working on very old pipe, crews should choose equipment suited to its condition.
Mid-Century Neighborhoods
West Highland Park and other areas filled with ranches and split-levels in the 1950s and 1960s. These homes typically have clay laterals and cast iron drains now fifty to seventy years old, and split-levels may have ejector pumps.
Root intrusion from mature trees is common. Regular rodding prevents most emergencies.
When lower-level fixtures back up while upstairs drains work, the ejector pump may be the cause.
Ravinia and Summer Crowds
Each summer, the Ravinia Festival draws hundreds of thousands of concertgoers to the Ravinia neighborhood, and the restaurants and shops in the Ravinia business district and downtown Highland Park see heavy traffic on concert nights. Commercial kitchens generate grease that can clog aging building laterals and the public sewer if interceptors are not maintained, and heavy restroom use in busy restaurants puts extra strain on older lines. Restaurant owners should have interceptors pumped on schedule and arrange hydro jetting of kitchen lines before the summer season begins.
The residential streets around Ravinia include many older homes from the early twentieth century, with clay laterals and mature trees. For those owners, a camera inspection establishes the lateral's condition, and a regular rodding schedule keeps roots from causing backups.
Fort Sheridan
Fort Sheridan, established in the 1880s as an Army post and closed in 1993, has been redeveloped with historic officers' homes and barracks converted to residences alongside new construction. Historic buildings there may have older plumbing adapted for residential use, while new homes have modern systems. Owners in converted historic buildings should know how their drains connect and whether laterals were replaced during redevelopment.
Sanitary Sewers and Backups
Highland Park's sanitary sewers are largely separate from storm sewers, but heavy rain can overload them through infiltration and improperly connected sump pumps or downspouts. A backwater valve protects your basement, and routing sump discharge appropriately helps prevent overloads. If several homes on your street back up at once, contact city public works.
Sump and Ejector Pumps
Test sump and ejector pumps at least once a year, replace units older than about ten years before they fail and add a battery backup to the sump pump. Make sure discharge lines do not drain onto ravine slopes.
Teardowns and New Construction
Many older Highland Park homes have been replaced with new construction. New homes include modern drains and basement protection, but service lines still connect to older public mains. Ask whether the lateral was replaced all the way to the main.
Winter and Spring Considerations
Frost and spring thaws stress buried pipe, especially on slopes. Test your sump pump before spring, clear gutters and have the main line checked if drains slow after a hard winter.

Prairie School Landmarks
Highland Park has one of the largest concentrations of Frank Lloyd Wright houses outside Oak Park, including the Ward Willits House of 1901, and many other architecturally significant homes by Prairie School and later modernist architects. Owners of these landmarks often face a delicate balance: plumbing must work reliably, but repairs should not damage original materials, landscaping or site features that give the homes their character. Laterals on such properties may be original, patched over the decades or partly replaced, and records are often incomplete.
A camera inspection with locating equipment is the essential first step. It shows exactly where the lateral runs, how deep it sits and where defects occur, so repairs can be planned with minimal disruption. Trenchless lining is often the preferred approach, renewing the pipe from inside without trenching through historic gardens or walkways. Interior drain work can usually be routed through basements and existing chases to avoid altering original finishes.
When to Call
Call when several drains slow at once, when a floor drain gurgles or when water rises in the tub as the toilet flushes. Early calls prevent basement backups.
Everyday Habits
Keep grease out of kitchen drains, flush only toilet paper, use hair catchers in showers and clean the washing machine's lint screen. Watch for gurgling drains, water rising in the tub when the toilet flushes or sewer odors, and call before a partial blockage becomes a backup into finished space.
