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 […]
Introduction In municipal water distribution and industrial fluid handling, the “valve selection paradox” is a frequent challenge for consulting engineers: the most expensive valve upfront is often the cheapest over 20 years, yet the wrong hydraulic application can destroy even the highest-quality equipment in weeks. A surprising statistic from hydraulic efficiency studies suggests that up […]
Introduction In the landscape of municipal and industrial water and wastewater treatment, the dry pit pump configuration remains a cornerstone of reliability, maintainability, and hydraulic versatility. Unlike submersible installations where the pump and motor are submerged in the process fluid, dry pit installations separate the fluid handling equipment from the wet well. The pump is […]
Introduction In municipal water distribution and wastewater treatment, the isolation valve is the most critical yet frequently overlooked asset. Industry data suggests that up to 20% of installed gate valves in North America are inoperable or pass water when isolation is attempted during an emergency. For the consulting engineer or utility director, the choice of […]
1. Introduction to Disinfection Systems in Water and Wastewater Treatment Disinfection remains the most critical unit process in the protection of public health within municipal and industrial water cycles. In potable water treatment, disinfection serves as the primary barrier against waterborne pathogens, ensuring the inactivation of bacteria, viruses, and protozoa before distribution. In wastewater treatment, […]
Designing and Operating Efficient Effluent Treatment Plants Regulatory Framework and Compliance Standards Did you know that nearly 40% of U.S. wastewater treatment plants are struggling to meet regulatory requirements? That's a staggering figure, especially when you consider the critical role these facilities play in protecting public health and the environment. If you're operating an effluent […]
