Outside the City of Vancouver's own utility, most sewered homes in unincorporated Clark County are served by Clark Regional Wastewater District. The district draws a clear line: its FAQ says it is responsible for the lateral from the main in the street to the property line cleanout, and customers are responsible for the private side sewer between the house and that cleanout, plus their internal plumbing.
That cleanout matters when something backs up. The district asks customers with a stoppage to stop using water and call its 24-hour line at 360-750-5876; crews come out to see whether the blockage is on the district's side or the homeowner's side. If there's no property line cleanout, the district may use the cleanout next to the home.

What Drives Pricing Here
- HomeGuide's published national average for replacing a residential sewer line is $6,000, with most jobs between $2,000 and $10,000.
- HomeGuide lists a camera inspection at $125 to $500, and per-foot trenchless pricing of $60 to $200 for pipe bursting and $90 to $250 for lining.
- District fees from its 2026 Septic Elimination Program brochure: a sewer connection permit is $110 and a grinder sewer connection permit is $250.
- Method: national ranges from HomeGuide, plus local district permit fees and the depth of the line; the short run to the property line cleanout keeps many side sewer jobs small.
- Converting a septic home costs far more because of connection charges: the Clark Regional Wastewater District brochure lists system development charges from $3,827 in Tier 1 to $11,468 in Tiers 3 and 4.
Permits & Local Rules
- Step 1, call the district: for a stoppage, Clark Regional Wastewater District crews decide whether the blockage is on the district's side or yours.
- Step 2, permit: the district FAQ says you must get a sewer permit any time you modify an existing sewer line outside the building, or install a new line and connect to sewer.
- Step 3, fee: the district's 2026 brochure lists the sewer connection permit at $110, or $250 for a grinder connection.
- Step 4, inspection: schedule the side sewer inspection with the district before covering the pipe.
- District rules are set out in the District Code; city customers in Vancouver, Camas, Battle Ground and Ridgefield follow their city's code instead.
Pipe Stock & Soil Notes
- Census ACS figures count 204,375 housing units in Clark County with a median year built of 1993, so many side sewers are PVC, but older homes near downtown Vancouver and Hazel Dell can have concrete or clay tile pipe.
- Tree roots from Douglas fir and big-leaf maple in older neighborhoods near Felida and Salmon Creek are a frequent cause of side sewer blockages.
- Wet winters raise the water table in low ground near the Columbia River, and saturated soils make deep trenches harder to keep open.
- Silty soils can settle under a side sewer, leaving a belly that holds water and solids.
- Freeze events are short here, but frost can still reach shallow pipe near the house.
