Introduction In municipal and industrial water treatment, the reliability of process analytics—pH, conductivity, dissolved oxygen, and turbidity—often hinges not on the sensor electronics, but on the mechanical interface with the process stream. A surprising 25% of premature sensor failures in wastewater applications are attributed to improper mounting, poor flow dynamics at the insertion point, or […]
The authoritative technical resource for the Hampton Roads Sanitation District’s flagship facility in Norfolk, Virginia. FACILITY BASIC INFORMATION Plant Name: Virginia Initiative Plant (VIP) Location: Norfolk, Virginia (4201 Powhatan Avenue) Operating Authority: Hampton Roads Sanitation District (HRSD) Design Capacity: 40.0 MGD (Hydraulic) Peak Hydraulic Capacity: 80.0 MGD Population Served: Approx. 200,000+ (Norfolk, sections of Virginia […]
Introduction The anaerobic digester gallery is arguably the most complex and hazardous environment within a Water Resource Recovery Facility (WRRF). Engineers are tasked with balancing two volatile forces: the biological/hydraulic requirement to keep sludge moving and heated, and the thermodynamic requirement to safely contain and manage explosive methane gas. A single specification error in either […]
Introduction The safety and structural integrity of anaerobic digesters rely entirely on the precise management of internal pressures. For decades, the specification of gas safety equipment has largely been a binary choice in the North American market. Engineers evaluating Varec Biogas (Ovivo) vs Shand & Jurs for Digestion applications are navigating a landscape defined by […]
FACILITY BASIC INFORMATION Plant Name: Blue River Wastewater Treatment Plant Location: 7300 Hawthorne Road, Kansas City, MO 64120 Operating Authority: KC Water (Kansas City Water Services Department) Design Average Flow: 105 MGD Peak Wet Weather Capacity: ~360 MGD (Secondary), ~960 MGD (Total Hydraulic) Population Served: ~300,000+ residents Service Area: Kansas City, MO (South of the […]
Introduction One of the most frequent points of failure in decentralized wastewater treatment is the misalignment between the chosen technology and the operational reality of the municipality. Engineers often design for steady-state compliance, overlooking the fact that small-to-mid-sized plants—ranging from 0.05 to 2.0 MGD—often face the most volatile hydraulic loading and the leanest staffing levels. […]
A Technical Profile of Southwest Indiana’s Primary Water Reclamation Facility FACILITY BASIC INFORMATION Plant Name: Evansville East Wastewater Treatment Plant (East WWTP) Location: 1301 South Waterworks Road, Evansville, IN 47713 Operating Authority: Evansville Water and Sewer Utility (EWSU) Design Capacity (Average): 22.5 MGD Peak Design Flow: 35.0 MGD (Secondary Treatment); >50 MGD (Wet Weather Capacity) […]
Introduction In municipal and industrial wastewater treatment, volume reduction is the single most effective method for controlling downstream costs. By thickening Waste Activated Sludge (WAS) from a typical 0.5–1.0% solids concentration to 5–7%, facilities can reduce the hydraulic volume sent to digesters or holding tanks by up to 85%. However, selecting the right equipment to […]
FACILITY BASIC INFORMATION Plant Name: Belmont Advanced Wastewater Treatment Plant (AWTP) Location: 2700 South Belmont Avenue, Indianapolis, Marion County, Indiana Operating Authority: Citizens Energy Group (Citizens Wastewater of Westfield, LLC) Design Capacity: 300 MGD (Peak Secondary Treatment), 120 MGD (Average Design) Current Average Flow: ~100-110 MGD Population Served: Approx. 800,000+ (Indianapolis/Marion County Metro) Service Area: […]
1) INTRODUCTION In the design of municipal water and wastewater infrastructure, the management of fluid dynamics and headspace containment represents a critical intersection of hydraulics, structural engineering, and environmental control. One of the most frequent trade-off analyses engineers face—particularly in surge control and storage applications—involves choosing between active pressurized containment and passive atmospheric covering. This […]
