Ultraviolet Disinfection: Safe and Effective Water Treatment Method In an age where clean water is paramount for public health, ultraviolet disinfection water treatment has emerged as a game-changer in ensuring safe drinking water. This innovative method harnesses the power of UV light to effectively eliminate pathogens without the use of harsh chemicals, making it both […]

The authoritative technical resource for the Great Miami River’s primary wastewater defense. FACILITY BASIC INFORMATION Plant Name: City of Dayton Water Reclamation Facility (DWRF) Location: 2800 Guthrie Road, Dayton, Montgomery County, Ohio Operating Authority: City of Dayton Department of Water Design Capacity: 72 MGD (Average Daily Flow), 200 MGD (Peak Hydraulic) Current Average Flow: ~48–55 […]

INTRODUCTION Grit removal efficiency is often the silent variable that dictates the lifespan of downstream biosolids equipment, clarifier drives, and digesters. While the civil design of grit chambers (vortex vs. detritor vs. aerated) garners significant attention during the design phase, the mechanism for extracting that captured grit—the grit pump—is the common failure point. Engineers often […]

FACILITY BASIC INFORMATION Plant Name: Walnut Creek Wastewater Treatment Plant (WWTP) Location: 7113 FM 969, Austin, Travis County, Texas 78724 Operating Authority: Austin Water (City of Austin) Design Capacity: 75.0 MGD (Average Annual) Peak 2-Hour Flow: 165.0 MGD Service Area: North and East Austin Receiving Water Body: Colorado River (Segment 1428) NPDES/TPDES Permit Number: WQ0010543011 […]

Introduction One of the most persistent operational headaches in modern wastewater treatment is the management of rags, wipes, and non-dispersibles. For municipal engineers and plant superintendents, the failure of headworks equipment does not just mean manual cleaning; it results in deragging pumps downstream, compromised biological processes, and significant unscheduled overtime. In the U.S. market, two […]

Location: Allen, Collin County, TexasOperating Authority: North Texas Municipal Water District (NTMWD)Design Capacity: 64 MGD (Annual Average)Receiving Water Body: Wilson Creek (Tributary to Lavon Lake) 1. Introduction The Wilson Creek Regional Wastewater Treatment Plant (RWWTP) serves as a cornerstone of environmental infrastructure for the rapidly growing Collin County region of North Texas. Owned and operated […]

Introduction Wisconsin’s wastewater infrastructure is defined by a unique combination of high-density urban treatment needs and significant industrial loading from the state’s robust food and paper processing sectors. The state operates under the regulatory oversight of the Wisconsin Department of Natural Resources (WDNR), which enforces some of the strictest phosphorus discharge limits in the United […]

Introduction Virginia’s wastewater infrastructure represents some of the most advanced treatment technology in the United States, driven largely by the stringent nutrient reduction mandates of the Chesapeake Bay Preservation Act. With a growing population of over 8.7 million and a geography ranging from the tidal coastal plains to the mountainous Blue Ridge, the state’s engineering […]

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. […]

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 […]
