Salem drains through the year
From October through May, rain saturates the clay soil and pushes water into cracked laterals, and roots grow fastest in spring.
Ice storms and occasional freezes can freeze crawlspace and garage pipes.

Before the plumber arrives
- 1
Stop the water
Pause the washer, dishwasher and showers.
- 2
Crawlspace?
If you smell sewage under the house, a crawlspace leak may be part of the problem.
- 3
Check the tub
In a crawlspace home, the tub or lowest toilet usually fills first.
- 4
Find the cleanout
Look by the front foundation or near the sidewalk.
Around the Capitol
Salem's oldest neighborhoods, near the Capitol, Willamette University and downtown, have Victorian and Craftsman homes on tree-lined streets. Grant and Court-Chemeketa are historic districts with homes from the late 1800s and early 1900s. Clay laterals under big street trees are often original, and roots are the leading cause of backups.
Rain and clay
The mid-Willamette Valley's heavy clay soils hold water through the long rainy season. Cracked laterals take in groundwater, and drains slow down during wet weeks. Sealing cracks and keeping downspouts out of the sewer reduce the load.
Fairmount Hill and South Salem
Fairmount Hill and South Salem have homes from the 1910s through the 1960s on sloping, wooded lots. Long laterals running downhill under big oaks and firs fill with roots, and steep runs can leave solids behind.
A typical Salem call
In November, a family in a 1922 bungalow in the Grant neighborhood finds the bathtub filling with dirty water when the washer drains. The plumber opens the outside cleanout and clears roots about thirty feet out, near a big maple. On the camera, clay joints have cracked and let in groundwater. They plan a liner.
Crawlspaces
Many Salem homes sit on crawlspaces, and the wet climate keeps them damp. Drain lines under the floor can leak, sag or separate. A musty smell or wet soil under the house is a sign to have them checked.
Postwar neighborhoods
Northeast and east Salem filled in from the 1950s through the 1980s with ranches and split-levels. Cast iron and concrete laterals from that era are aging, with scale, cracks and roots common.
West Salem
West Salem, across the Willamette, has older homes near the river and newer hillside subdivisions. Hillside lots have steep laterals, and some homes below the street rely on pumps.
State workers and busy households
Many Salem residents work for the state, and busy households mean a lot of cooking and laundry. Grease and wipes cause most clogs in newer homes.
Restaurants downtown
Downtown Salem's restaurants and the corridors along Lancaster Drive and Commercial Street have many kitchens. Interceptors pumped on schedule keep them from backing up.
Ice storms
Salem gets occasional ice storms that knock out power and freeze pipes in crawlspaces and garages. Close crawlspace vents during cold snaps and let a faucet drip.
Willamette University and rentals
Willamette University sits next to the Capitol, and older homes nearby are often rented to students and young state workers. Heavy use through old clay laterals means more clogs, especially at the start of each semester.
A camera inspection between tenants is a cheap way for owners to catch roots before they block the line.
Mill Creek and low ground
Mill Creek, Pringle Creek and Shelton Ditch run through central Salem, and the neighborhoods near them sit on lower ground. Heavy rain raises groundwater there, and the 1996 flood swamped parts of the city. Cracked laterals near the creeks take in more water during wet spells.
Downspouts and footing drains
Many older Salem homes were built with roof downspouts and foundation footing drains tied directly into the sewer lateral. In a city that sees months of steady rain, that sends a lot of clean water into the sanitary system and can overload a lateral that's already narrowed by roots. Rerouting downspouts to splash blocks or rain gardens, and sending footing drains to a sump instead of the sewer, takes a real load off the line.
Keizer and the north end
North of downtown, Salem blends into Keizer, with neighborhoods of ranches and split-levels built from the 1960s through the 1980s for families who worked at the state, the canneries and the food processing plants along the river. Many of those homes sit on crawlspaces, with concrete or early plastic laterals now forty to sixty years old. Roots and offset joints are common, and some homes still have the original cast iron under the floor.
Hazelnut country and septic
Salem is surrounded by farmland, orchards and hazelnut groves, and some properties on the edges of the city and in unincorporated Marion and Polk counties still use septic systems. In the heavy valley clay, drain fields can saturate for weeks in winter, and a slow drain on septic often means a full tank or a waterlogged field rather than a clog. If your home isn't on city sewer, tell the plumber.
Information to have ready
Share the neighborhood, the home's age, whether it's on a crawlspace or basement and whether the lot is hilly. Say whether any big oaks or maples stand near the line and whether the trouble started during a wet stretch.
