Introduction The modern wastewater stream has undergone a radical transformation in the last two decades. The proliferation of non-dispersible synthetic fabrics—commonly known as “flushable” wipes—combined with water conservation mandates that reduce transport velocities, has created a perfect storm for municipal and industrial operators. For engineers involved in lift station design and treatment plant operations, the […]
Introduction One of the most insidious threats to the longevity of large-scale pumping systems is the phenomenon of air entrainment caused by intake vortices. For municipal and industrial engineers, the challenge is compounded when geotechnical constraints force the use of deep, circular containment structures. Diaphragm Wet Well Design and Minimum Submergence to Prevent Vortexing is […]

Introduction In municipal wastewater treatment and industrial sludge handling, the premature failure of progressive cavity (PC) pump stators remains one of the most persistent and costly maintenance burdens. Engineers frequently specify robust hydraulic conditions, yet the interface between the pump mechanics and the electrical control system is often where reliability disintegrates. A startling volume of […]

Introduction One of the most frequent points of failure in municipal pumping infrastructure involves the misapplication of pump geometry to the wet well environment. While submersible non-clog pumps dominate small to medium sewage lift stations, engineers frequently turn to vertical turbine pumps (VTPs) for high-flow, high-head, or footprint-constrained applications. However, a staggering number of these […]

Introduction The failure of a chemical feed system or sludge transfer unit in a water treatment plant often isn’t caused by a defective pump; it is caused by a failure in the commissioning process. In municipal and industrial applications, up to 60% of early-life equipment failures can be traced back to improper installation, inadequate pipe […]
