The water main replacement program has significantly reduced water main failures since it began in 1992. Visit our charts page to view the decreases in failures.
Corrosion caused by Fargo's aggressive soils ranks as the top reason for water main failure. Mains made of PVC plastic are used to replace those made from cast iron.
