Introduction The degradation of municipal infrastructure is rarely the result of sudden catastrophic force; rather, it is the slow, relentless electrochemical and biological breakdown of assets. For water and wastewater engineers, the total annual direct cost of corrosion is estimated in the billions, yet it remains one of the most frequently underestimated factors in plant […]

Introduction to Equipment Diagnostics in Water Utilities A staggering 50% of maintenance costs in municipal water and wastewater utilities are often attributed to “reactive” work—fixing assets after they have already failed. While run-to-failure remains a valid strategy for non-critical lightbulbs, it is a catastrophic financial and operational strategy for raw sewage pumps, finished water centrifuges, […]

Introduction For municipal water and wastewater engineers, the adoption of Variable Frequency Drives (VFDs) has been the single most significant advancement in energy efficiency and process control over the last three decades. However, this transition has introduced a pervasive, silent reliability killer that often goes misdiagnosed as mechanical failure or lubrication breakdown. A surprising industry […]

Introduction One of the most persistent challenges facing municipal engineers today is the accurate monitoring of Combined Sewer Overflows (CSOs) and stormwater systems under regulatory consent decrees. The engineering challenge is multifaceted: equipment must survive in harsh, rag-prone environments, operate reliably during rapid hydraulic changes, and provide data accurate enough to satisfy environmental agencies. A […]

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 […]

Location: Newark, Essex County, New JerseyOperating Authority: Passaic Valley Sewerage CommissionDesign Capacity: 330 MGD (Average) / 720 MGD (Peak)Service Area: 48 Municipalities across 5 Counties 1. INTRODUCTION The Passaic Valley Sewerage Commission (PVSC) Newark Bay Treatment Plant is one of the largest wastewater treatment facilities in the United States and the largest in the Northeast. […]

Introduction The movement of dewatered biosolids, screenings, and grit is often the final bottleneck in modern treatment facilities. While headworks and biological processes receive significant engineering attention, the conveyance of “cake” solids remains a frequent source of operational headaches, from housekeeping nightmares to complete mechanical failures. Engineers tasked with facility upgrades often face a critical […]

Introduction The Southerly Wastewater Treatment Center (Southerly) stands as the largest of the three wastewater treatment facilities operated by the Northeast Ohio Regional Sewer District (NEORSD). Located in the Village of Cuyahoga Heights, this critical infrastructure asset provides advanced wastewater treatment for a service area covering more than 600,000 residents across the Greater Cleveland area. […]

Introduction Colorado sits at a unique geographical and regulatory intersection within the United States water sector. As a headwaters state, the effluent quality from Colorado’s wastewater treatment plants (WWTPs) dictates the water health for millions of downstream users in the Colorado, Platte, Arkansas, and Rio Grande river basins. Consequently, the state maintains some of the […]

The authoritative resource for consulting engineers, utility managers, and infrastructure professionals tracking Georgia’s water reclamation sector. 1. Introduction: Georgia’s Water Reclamation Landscape Georgia’s wastewater infrastructure is defined by a unique combination of rapid metropolitan growth, strict regulatory requirements due to interstate water sharing (the Tri-State Water Wars), and a diverse geography ranging from the Appalachian […]
