WASTEWATER
By Rick LallishConditions recognized as major operating problems causing poor performance or failure of wastewater collections systems are known as what?A. Industrial dischargesB. Peripheral lateral dischargesC. Inflow and InfiltrationD. Fouled lift stationsAnswer: C. Inflow and infiltration problems have been overlooked for decades. Many municipalities have adopted the out-of-sight, out-of-mind approach. This has caused many to scramble to find funds to correct for years of neglect. Inflow and infiltration problems are the leading cause of excessive hydraulic overloads, private-home sewage backups, and premature failure of the collection system.
