INTRODUCTION The axially split case centrifugal pump remains the workhorse of the water and wastewater industry. Its robust design, high flow capabilities, and relative ease of maintenance—allowing access to rotating assemblies without disturbing piping—make it a staple in raw water intakes, high-service pump stations, and large-scale cooling loops. However, despite their inherent durability, these assets […]

Introduction In municipal water treatment and industrial wastewater processing, the chemical metering pump is often the smallest piece of rotating equipment with the highest disproportionate impact on process reliability. When a main lift pump fails, redundancy often covers the gap. When a chemical metering pump fails, regulatory compliance regarding disinfection, coagulation, or pH adjustment is […]

Introduction to High-Volume Pumping Systems In the realm of municipal stormwater management and large-scale raw water intake, the axial flow (propeller) pump is the workhorse of the industry. However, these high-flow, low-head machines are notoriously sensitive to installation conditions and hydraulic environments. A surprising statistic from reliability studies indicates that nearly 60% of premature failures […]

INTRODUCTION In municipal water distribution and wastewater treatment, the vertical turbine pump (VTP) is a workhorse, valued for its efficiency and small footprint. However, when paired with Variable Frequency Drives (VFDs) without rigorous thermal and mechanical analysis, these systems frequently suffer from premature failure. A surprising industry statistic suggests that up to 30% of vertical […]

Editor’s Note: While frequently associated with municipal infrastructure in Springfield, the wastewater treatment facilities are operated by the Sangamon County Water Reclamation District (SCWRD), a distinct entity from City Water, Light and Power (CWLP), which manages power generation and drinking water purification. This article focuses on the Spring Creek Water Reclamation Plant, the primary wastewater […]
