INTRODUCTION For municipal and industrial wastewater treatment plants, aeration typically accounts for 50% to 70% of total plant energy consumption. Consequently, the selection of air generation technology is arguably the single most critical decision influencing a facility’s 20-year operational expenditure (OPEX). Engineers tasked with upgrades or new plant designs frequently encounter a choice between market […]
A Critical Resiliency & Nutrient Removal Facility Serving the Rockaway Peninsula FACILITY BASIC INFORMATION Official Name: Rockaway Water Resource Recovery Facility (WRRF) Location: 106-21 Beach Channel Drive, Rockaway Park, Queens, NY 11694 Operating Authority: New York City Department of Environmental Protection (NYC DEP) Design Capacity: 45 MGD (Dry Weather Flow) Peak Wet Weather Capacity: 90 […]
1. Introduction In the architecture of modern municipal and industrial water and wastewater treatment infrastructure, instrumentation serves as the central nervous system. While pumps, blowers, and valves perform the physical work of moving and treating fluids, it is the instrumentation—flow meters, level sensors, pressure transmitters, and analytical probes—that provides the data necessary to control these […]
Introduction In the modern era of wastewater infrastructure, the shift toward submersible pumping technology has been substantial. However, a significant percentage of municipal lift stations and treatment plants rely on the durability and accessibility of conventional dry pit pumps. Engineers frequently overlook the long-term operational benefits of separating the driver from the hydraulic fluid, particularly […]
1. Introduction In the modern landscape of municipal and industrial water and wastewater treatment, the electric valve actuator serves as the critical interface between the control room (SCADA) and the physical process. While the valve body itself—whether a gate, butterfly, plug, or ball valve—dictates the hydraulic characteristics of the system, the electric actuator determines the […]
Introduction: The State of Kansas Water Infrastructure Kansas presents a unique dichotomy in wastewater infrastructure, characterized by sophisticated, high-capacity biological nutrient removal (BNR) facilities in the rapid-growth corridors of Johnson County and Wichita, contrasted with hundreds of lagoon systems serving rural communities. For municipal consulting engineers and utility managers, the Kansas market is currently defined […]
Last Updated: October 2023 1. Introduction Louisiana’s wastewater infrastructure operates within one of the most hydro-geologically complex environments in the United States. Managing treatment capacity in a state defined by high water tables, subsidence, and significant industrial activity presents unique challenges for utility managers and consulting engineers. The state’s infrastructure is overseen by the Louisiana […]
Executive Summary: Arizona is a national leader in water reclamation and reuse. With the Colorado River shortage intensifying, the state is heavily investing in Advanced Water Purification (AWP) for Direct Potable Reuse (DPR). Current active capital projects exceed $1.5 billion, focusing on capacity expansion in the rapid-growth “Sun Corridor” and technological retrofits for aquifer recharge. […]
Last Updated: October 2023 1. Introduction The District of Columbia operates a unique water infrastructure model compared to traditional U.S. states. The region relies entirely on the District of Columbia Water and Sewer Authority (DC Water), which operates the Blue Plains Advanced Wastewater Treatment Plant—the largest advanced wastewater treatment facility of its kind in the […]
Introduction: The State of New Jersey’s Water Infrastructure New Jersey represents one of the most complex and dense water infrastructure environments in the United States. As the most densely populated state in the nation, New Jersey’s wastewater sector manages a massive hydraulic load through a network of approximately 260 dedicated wastewater treatment plants (WWTPs). The […]
