Plumbing in Bellingham
Bellingham drinks from Lake Whatcom, a 250-billion-gallon lake fed by 36 streams and topped up at times with water diverted from the Middle Fork of the Nooksack River. Water flows through a 1,200-foot wooden pipeline to the treatment plant in Whatcom Falls Park and on to more than 100,000 customers. The city's 2025 report lists hardness at 21.8 mg/L, which is soft, and says Bellingham has no lead service lines.
By city ordinance, your side sewer is your responsibility, including the stretch from the property line to the main and the connection itself, and Public Works tells owners when video or smoke testing finds roots or holes. Winters can bite: on January 12, 2024, during a Fraser Outflow, Bellingham International Airport set a daily record low of 3 degrees while gusts topped 50 mph in northwest Whatcom County.

Local know-how
What's hard on plumbing in Bellingham.
Brace for Fraser Outflow freezes
Northeast Fraser Outflow winds can push Bellingham into single digits, as on January 12, 2024. Before a cold snap, insulate pipes in crawlspaces and outside walls, disconnect hoses, and find your main shutoff. If a pipe bursts, our emergency line answers 24/7.
Older homes, original pipes
Nearly a quarter of Bellingham homes predate 1960, when galvanized supply pipe was common, and 43% predate 1980, the era of cast-iron drains. Rusty water, weak pressure and slow drains are cues to inspect; we camera-check drains and quote repiping upfront.
Keep grease and wipes out
Bellingham Public Works warns that food scraps, fats, oils, grease and most wipes cause costly sewage backups. Scrape plates into the trash and toss wipes. If your side sewer still clogs, we clear it with hydro-jetting and check it by camera.
Water running right now?
Shut off the main water valve, turn off the water heater, and call us. Our emergency line answers 24/7.

Good questions
Bellingham plumbing FAQ.
Don't see your question? Call or text (425) 845-3535. A real person answers, 24/7.
Is Bellingham's water hard?
No. The City of Bellingham's 2025 water quality report lists hardness at 21.8 mg/L, which is soft on the USGS scale. The water comes from Lake Whatcom and is treated at the plant in Whatcom Falls Park, where sodium carbonate is added after filtration. With water this soft, a water heater's age usually matters more than mineral scale.
Who is responsible for my side sewer in Bellingham?
You are. By city ordinance, Bellingham is not responsible for side sewers: the property owner owns and maintains the line, including the stretch from the property line to the main and the connection at the main. The city notifies owners when video or smoke testing finds roots or holes. We can camera-inspect the line, clear roots and repair or replace it.
