HUMBOLDT — Misinterpretation of a video inspection of sewer mains will lead to Humboldt’s sewer improvement project costing an additional $136,000, council members learned Thursday evening.

When better than 7,000 feet of mains were inspected in 2016, they were all thought to be 18 inches in diameter. More recently it was found about 3,000 feet were 21-inch.

The bigger diameter requires more liner, and thus a higher cost. The liner seals off infiltration during wetter weather, and prevents sewage escaping during dry weather when the soil contracts and pulls away from mains.
