Manhole rehabilitation is a constant necessity for utility departments and municipalities throughout the country. Corrosion caused by hydrogen sulfide (H2S) cannot be avoided, often leading to strained city budgets when issues are not dealt with until problems occur. The city of Fairmont, Minnesota is one of many cities throughout the country involved in the growing trend of protecting assets prior to failure and catastrophic damage to get ahead of the inevitable issues that occur when manholes are left unprotected.

The city of Fairmont’s wastewater collection system utilizes 75 miles of sewer lines with 30 lift stations. During routine inspection, one of the sanitary sewer force main manholes within the collection system was identified as a turbulent manhole. The city decided to take the proactive measure of lining this two-year-old precast manhole, which has a 6′ diameter at the base and tapers to 4’ x 13’ deep, to protect the asset from any future corrosion and deterioration that would require costly measures to correct.
