INTRODUCTION One of the most persistent and costly misconceptions in municipal and industrial water treatment is viewing a wet well merely as a concrete holding tank. In reality, the wet well is a complex hydraulic structure that dictates the reliability of the pumping equipment. A startling number of premature pump failures—often attributed to “defective manufacturing”—are […]
INTRODUCTION The integration of Variable Frequency Drives (VFDs) with non-clog wastewater pumps has become the standard for modern municipal lift stations and treatment plants. While VFDs offer significant benefits regarding energy efficiency, flow matching, and reduced mechanical stress during startup, they introduce complex thermal challenges that are often underestimated during the design phase. A critical […]
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 […]
FACILITY BASIC INFORMATION Plant Name: Tomahawk Creek Wastewater Treatment Facility (TCWWTF) Location: Leawood, Kansas (Serving Overland Park and Johnson County) Operating Authority: Johnson County Wastewater (JCW) Design Capacity: 19 MGD (Average Daily Flow) / 172 MGD (Peak Wet Weather) Current Average Flow: ~10-12 MGD Population Served: Approx. 150,000 residents Service Area: Overland Park, Leawood, Prairie […]
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 […]
