INTRODUCTION One of the most dangerous and costly mistakes an engineer can make in municipal or industrial water treatment design is treating chemical feed piping like standard water infrastructure. Specifying a generic 316 stainless steel valve for a seemingly routine disinfection or coagulation process frequently results in rapid, catastrophic failure. Dealing with Control Valves for […]
This case study looks inside detroit water and sewerage operations to show how a large urban utility coordinates treatment, distribution, and financing at scale. We unpack the governance split with the Great Lakes Water Authority, the treatment train and SCADA strategies used to protect drinking water quality, and collection system practices for CSO control and […]
INTRODUCTION One of the most persistent challenges in municipal water distribution engineering is maintaining water quality at the extremities of the system. Dead-end mains, low-demand subdivisions, and oversized pipes inevitably lead to high water age, loss of disinfectant residuals, and the formation of dangerous Disinfection Byproducts (DBPs) such as Trihalomethanes (THMs) and Haloacetic Acids (HAAs). […]
Effluents from municipal and industrial sources drive most operational headaches and permit risk at wastewater plants. This how-to guide provides a practical, technically detailed roadmap to design and operate effluent monitoring programs, select pretreatment and treatment strategies, and improve discharge quality while managing CAPEX, OPEX, and regulatory exposure. Expect clear decision criteria, sampling and QAQC […]
Introduction For municipal water utilities, Non-Revenue Water (NRW) represents a significant financial and operational hemorrhage. While aging distribution networks are often the primary culprit, poor installation practices for ancillary equipment contribute disproportionately to this loss. Automatic flushing devices (AFDs) are essential tools for managing water age, maintaining chlorine residuals, and removing sediment in dead-end mains. […]
Introduction to High-Volume Pumping Systems In the realm of municipal stormwater management and large-scale raw water intake, the axial flow (propeller) pump is the workhorse of the industry. However, these high-flow, low-head machines are notoriously sensitive to installation conditions and hydraulic environments. A surprising statistic from reliability studies indicates that nearly 60% of premature failures […]
Effluent Discharge Standards: Compliance and Best Practices Article Overview Article Type: How-To Guide Primary Goal: Equip municipal managers, plant operators, design engineers, and equipment manufacturers with a practical, technically rigorous roadmap to interpret effluent discharge standards, design and operate treatment systems to meet permits, implement reliable monitoring and reporting, and future-proof facilities for emerging contaminants […]
