FACILITY BASIC INFORMATION Plant Name: Stickney Water Reclamation Plant Location: Cicero/Stickney, Cook County, Illinois Operating Authority: Metropolitan Water Reclamation District of Greater Chicago (MWRD) Design Capacity: 1,200 MGD (Average) / 1,440 MGD (Max) Current Average Flow: ~700 MGD Population Served: 2.3 Million residents Service Area: 260 square miles (Central Chicago + 43 suburban municipalities) Receiving […]
Introduction In municipal wastewater lift stations and industrial effluent sumps, the submersible pump is often the most critical, yet least visible, asset. Because these units operate beneath the liquid surface, visual inspection during operation is impossible. Consequently, engineers and operators must rely heavily on external data and performance anomalies to identify impending failures. A surprising […]
Clarifier Tanks: How They Separate Solids in Treatment Article Overview Article Type: Informational Primary Goal: Explain how clarifier tanks remove and concentrate suspended solids in wastewater, provide the engineering principles and design parameters used to size and operate clarifiers, and give practical troubleshooting, retrofit, and vendor selection guidance for municipal and industrial wastewater professionals Who […]

FACILITY BASIC INFORMATION Plant Name: Five Mile Creek Water Reclamation Facility Location: Graysville/Birmingham, Jefferson County, Alabama Operating Authority: Jefferson County Environmental Services Department (JCESD) Design Capacity: 20.0 MGD Peak Hydraulic Capacity: 60.0 MGD Service Area: Northern Jefferson County (Forestdale, Graysville, Fultondale, Gardendale) Receiving Water Body: Five Mile Creek (Tributary to Locust Fork) NPDES Permit Number: […]
Lagoon Treatment Systems: Natural Wastewater Processing Article Overview Article Type: Informational Primary Goal: Provide municipalities, design engineers, plant operators, and equipment manufacturers with a practical, technically rigorous guide to lagoon treatment system selection, design, operation, performance expectations, limitations, and upgrade strategies so they can evaluate whether a lagoon system is appropriate and how to design […]
Introduction In high-volume municipal flood control, stormwater management, and industrial water transport, the axial flow “propeller” pump is the workhorse of the hydraulic world. However, their unique specific speed characteristics and sensitivity to intake conditions make them prone to issues that differ significantly from standard centrifugal pumps. Engineers and operators frequently overlook the subtle precursors […]
FACILITY BASIC INFORMATION Plant Name: Waterbury Water Pollution Control PlantLocation: 210 Municipal Road, Waterbury, New Haven County, CT 06708Operating Authority: City of Waterbury (Contract Operations: Jacobs/CH2M)Design Capacity: 27.0 MGDCurrent Average Flow: ~15-18 MGDPopulation Served: ~110,000 (Direct); Regional solids handling for ~30 communitiesService Area: City of Waterbury, Town of Watertown, Town of WolcottReceiving Water Body: Naugatuck […]
INTRODUCTION One of the most persistent challenges in municipal and industrial fluid handling is not the pump itself, but the configuration of the installation. Engineers frequently encounter systems where high-quality rotating assemblies fail prematurely due to poor intake design, inaccessible valving, or structural resonance—issues directly tied to the physical installation method. Statistics from major utility […]
Introduction In municipal and industrial water treatment infrastructure, the reliability of auxiliary equipment often dictates the resilience of the entire process. While massive raw sewage lift pumps garner the majority of capital planning attention, the failure of miscellaneous pumps—seal water systems, polymer feed pumps, sampling units, and dry-pit sump pumps—frequently triggers permit violations or costly […]
