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 […]

Greywater Recycling: Sustainable Water Reuse Solutions Greywater recycling systems provide a practical route to cut potable water use and reduce sewer loads in municipal and large-building projects. This article delivers the engineering, regulatory, and lifecycle guidance needed to scope, specify, and operate nonpotable greywater reuse at scale, with performance targets, instrumentation and monitoring requirements, and […]

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 Chemical dosing accuracy is the silent guardian of water quality compliance and the hidden driver of operational expenditure. In municipal and industrial treatment plants, the failure to properly understand hydraulic behavior results in millions of dollars lost annually to chemical waste, premature equipment failure, and process instability. A surprising industry statistic suggests that over […]

Chlorine Disinfection for Water Treatment: Safety and Effectiveness Chlorine disinfection water remains the workhorse for municipal drinking and wastewater systems because it delivers rapid inactivation of many pathogens and a persistent distribution residual. This article gives engineers and operators practical, implementation-focused guidance on how chlorine inactivates organisms, CT calculations with worked examples, dosing and contact […]

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 […]

Biosolids Management: Best Practices for Treatment Plants Biosolids management is where regulatory pressure, operational cost, and community risk collide—get the decisions right and you control disposal costs and recover resources; get them wrong and you face fines, complaints, and rising hauling bills. This practical guide gives treatment plant operators and engineers a technical roadmap for […]

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 […]
