FACILITY BASIC INFORMATION Plant Name: Howard F. Curren Advanced Wastewater Treatment Plant (HFCAWTP) Location: 2700 Maritime Boulevard, Tampa, Hillsborough County, Florida Operating Authority: City of Tampa Wastewater Department Design Capacity: 96 MGD (Annual Average Daily Flow) Current Average Flow: ~55-60 MGD Population Served: ~720,000 residents Service Area: City of Tampa and portions of unincorporated Hillsborough […]
Introduction One of the most persistent and expensive challenges in wastewater treatment plant (WWTP) operation is the downstream devastation caused by inorganic solids. Pumps with eroded impellers, clogged digestion tanks, and abrasive wear on sludge dewatering equipment cost utilities millions annually in preventable maintenance. Yet, headworks design often suffers from “copy-paste” specifications that fail to […]
1. Introduction The oxidation ditch is a modified activated sludge biological treatment process that utilizes long solids retention times (SRTs) to remove biodegradable organics. Oxidation ditches are typically complete mix systems, but they can be modified to approach plug flow conditions. Ideally suited for small- to medium-sized municipal wastewater treatment plants, these systems are renowned […]
The primary wastewater treatment facility serving Newark and Essex County, New Jersey. FACILITY BASIC INFORMATION Plant Name: Newark Bay Treatment Plant Location: 600 Wilson Avenue, Newark, Essex County, New Jersey Operating Authority: Passaic Valley Sewerage Commission (PVSC) Design Capacity: 330 MGD (Annual Average) Peak Wet Weather Capacity: ~720 MGD Population Served: 1.5 million residents Service […]
Introduction For municipal and industrial wastewater engineers, the protection of downstream process equipment—pumps, valves, centrifuges, and digesters—starts at the headworks. The improper reduction of solids or the inefficient separation of inorganic grit can lead to catastrophic pump cavitation, seal failures, and the rapid accumulation of rag balls in digesters that necessitates expensive cleanouts. When specifying […]
The authoritative technical resource for the Camden County Municipal Utilities Authority (CCMUA) wastewater treatment system. FACILITY BASIC INFORMATION Plant Name: Delaware No. 1 Water Pollution Control Facility Location: Camden, Camden County, New Jersey (Waterfront South) Operating Authority: Camden County Municipal Utilities Authority (CCMUA) Design Capacity: 80 MGD Current Average Flow: ~58 MGD Population Served: ~500,000 […]
INTRODUCTION Grit accumulation remains one of the most pervasive and costly “silent failures” in municipal wastewater treatment. While headworks screens provide visible capture, grit often bypasses preliminary treatment, settling in aeration basins, reducing digester capacity by up to 30%, and causing premature abrasion failure in downstream pumps. For consulting engineers and plant directors, the selection […]

Introduction In the municipal and industrial water sector, data integrity is the bedrock of process control. Yet, a surprisingly high percentage of plant alarms—estimated by some automation audits to be over 40%—are nuisance alarms caused not by process failures, but by instrumentation drift, fouling, or improper specification. For the design engineer or plant superintendent, the […]
FACILITY BASIC INFORMATION Plant Name: Jackson Pike Wastewater Treatment Plant Location: 2104 Jackson Pike, Columbus, Franklin County, Ohio Operating Authority: City of Columbus, Department of Public Utilities (Division of Sewerage and Drainage) Design Capacity: 68 MGD (Average Daily Flow) / 102 MGD (Peak Secondary) / 150 MGD (Peak Hydraulic with CEPT) Current Average Flow: ~60-65 […]
