Introduction In the hierarchy of wastewater treatment equipment, process pumps often receive the bulk of engineering attention. However, the humble dewatering pump acts as the critical fail-safe for plant operations. Engineers frequently encounter a scenario where a tank needs emergency draining, or a gallery floods during a storm event, only to find the portable or […]

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 […]

1) INTRODUCTION In the design of municipal water and wastewater infrastructure, the management of fluid dynamics and headspace containment represents a critical intersection of hydraulics, structural engineering, and environmental control. One of the most frequent trade-off analyses engineers face—particularly in surge control and storage applications—involves choosing between active pressurized containment and passive atmospheric covering. This […]

Introduction In the transition from traditional cast iron sluice gates to modern fabricated stainless steel and aluminum slide gates, municipal engineers often find themselves evaluating two dominant North American manufacturers. The analysis of Golden Harvest vs Whipps – C for Gates: Pros/Cons & Best-Fit Applications is a critical exercise for any design engineer or utility […]

Introduction For municipal and industrial engineers, the failure of a water control gate is rarely a minor operational annoyance; it is a critical vulnerability that can lead to catastrophic flooding, regulatory non-compliance, and significant safety hazards. While pumps often receive the lion’s share of attention in hydraulic modeling, the static and dynamic isolation provided by […]

Introduction In the realm of municipal and industrial wastewater treatment, sludge management typically accounts for 30% to 50% of a plant’s total operating costs. The efficacy of the dewatering process is the linchpin of this economic equation. While centrifuges and screw presses have gained market share in recent decades, the belt filter press (BFP) remains […]

Introduction In the hydraulic architecture of municipal and industrial water and wastewater systems, the plug valve occupies a critical niche, balancing the requirements of reliable isolation with the capability for throttling flow control. Unlike gate valves, which are strictly for on/off service, or butterfly valves, which may struggle with heavy solids, the plug valve—specifically the […]

Introduction In the municipal water and wastewater sector, the failure of a critical valve actuator is rarely a minor inconvenience; it is often a precursor to permit violations, process upsets, or catastrophic flooding. For decades, design engineers and plant superintendents have faced a polarized choice when specifying electric actuation: adhere to traditional domestic manufacturing philosophies […]

Introduction For municipal and industrial treatment plant engineers, sludge handling often represents the single largest line item in the operational budget. With biosolids disposal costs frequently accounting for 30% to 50% of a facility’s total operating expenses, the efficiency of the dewatering process is not merely a technical detail—it is a critical financial lever. A […]

Introduction   The escalation of non-dispersible solids in municipal wastewater—specifically the “ragging” phenomenon caused by synthetic wipes—has transformed solids reduction from a luxury to a necessity. For consulting engineers and plant operators, the failure to adequately protect downstream pumps and dewatering equipment results in catastrophic downtime. Industry data suggests that unscheduled maintenance due to ragging […]
