1. Introduction Maryland’s wastewater infrastructure is defined by a single, overriding geographical feature: the Chesapeake Bay. As the largest estuary in the United States, the Bay dictates the regulatory and technological landscape for the state’s water environment. Maryland is home to approximately 320 public wastewater treatment plants (WWTPs) that treat over 650 million gallons of […]
1. Introduction North Carolina stands at a critical juncture in water infrastructure management. With one of the fastest-growing populations in the United States—driven by the rapid expansion of the Charlotte metro area and the Research Triangle (Raleigh-Durham)—the state’s wastewater treatment capacity is under significant pressure. The North Carolina Department of Environmental Quality (NC DEQ) oversees […]
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 Pennsylvania’s wastewater infrastructure represents one of the most complex and historic networks in the United States. With a unique topography that spans the Delaware, Susquehanna, and Ohio River basins, the Commonwealth manages a vast array of treatment facilities ranging from massive metropolitan plants in Philadelphia and Pittsburgh to critical rural lagoons. Currently, Pennsylvania faces […]
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 […]
Introduction In the design of water and wastewater treatment facilities, the rapid and uniform dispersion of chemicals—coagulants, disinfectants, and neutralizing agents—is a fundamental determinant of process efficiency. A surprising statistic in the municipal sector indicates that up to 30% of chemical costs are wasted due to inefficient mixing, leading to overdosing to achieve regulatory compliance. […]

Technical Note for Engineers: This article provides a specification-level overview of Solids Dewatering Equipment for municipal and industrial applications. It focuses on engineering selection criteria, operational realities, and an impartial analysis of specific Original Equipment Manufacturers (OEMs). 1. Introduction Solids dewatering represents one of the most critical unit operations in the water and wastewater treatment […]
Introduction One of the most persistent challenges in water and wastewater engineering is the interface between disparate systems. Whether connecting a new ductile iron pipeline to an existing asbestos-cement main, retrofitting a modern submersible pump onto a 30-year-old discharge elbow, or automating manual valves with electric actuators, the success of the project often hinges on […]
Introduction Aeration systems represent the single largest energy consumer in biological wastewater treatment, typically accounting for 50% to 75% of a facility’s total electrical demand. For decades, the industry relied on robust but inefficient positive displacement (PD) lobe blowers or uncontrolled multistage centrifugal systems. However, the modern regulatory environment, characterized by strict nutrient limits and […]
