  • FOG Waste receiving and processing facility design considerations

    Fats, Oils, and Grease (FOG) wastes and high-strength wastes (HSW) are frequently received at municipal water resource recovery facilities (WRRFs) as trucked-in wastes. These wastes offer significant benefits in terms of revenue from tipping fees and feedstock for co-digestion in anaerobic digesters that produce biogas, which can be beneficially used as fuel. The number of treatment plants ...

  • What too much water can do to your collection systems

    In areas with a high water table, or for cities more prone to flooding, your underground infrastructure can become inundated with groundwater and stormwater. And despite stormwater systems being built for this type of collection, there are a number of things that can go wrong for both types of collection systems underground—and above ground—that can lead to contamination or degraded ...

  • Area-Velocity Flowmeter Installations in Denmark - Case Study

    Area-Velocity Flow Meters are designed to monitor flow rates in partially filled pipes and open channels without flumes or weirs. A sealed ultrasonic sensor is mounted on the bottom of the pipe or channel and connected to electronics through a watertight cable. The sensor measures both level and velocity and when calibrated with the pipe diameter or channel dimensions, the Greyline AVFM ...

  • Dutch Utility Inspects Rising Main With Acoustic Tool And Reduces Risk On Critical Asset

    It’s a major event when you’ve been asked to perform a first in terms of a pipeline inspection. For starters, you must feel confident in the inspection technology you recommend. Second, you hope that all your planning for deployment and unexpected contingencies has been anticipated. And finally, with so many eyes focused on the outcome, you hope the first inspection of its kind goes ...

  • Flood forecasting within urban drainage systems using NARX neural network

    Urbanization activity and climate change increase the runoff volumes, and consequently the surcharge of the urban drainage systems (UDS). In addition, age and structural failures of these utilities limit their capacities, and thus generate hydraulic operation shortages, leading to flooding events. The large increase in floods within urban areas requires rapid actions from the UDS operators. ...

  • Measuring Wastewater Below Ground

    Measuring wastewater is one of the most difficult water management tasks that exists. While some wastewater flows are easy to access, others are very hard to measure because they are in open channel conditions and are below grade. If you need to measure below ground wastewater flow, there are a few factors that you need to consider to help you choose the right tool for the job. With a ...

  • A comparison of three dual drainage models: shallow water vs local inertial vs diffusive wave

    In this study we compared three overland flow models, a full dynamic model (shallow water equation), a local inertial equations model (gravity wave model), and a diffusive wave model (parallel diffusive wave model). The three models are coupled with the same full dynamic sewer network model (SIPSON). We adopted the volume exchange between sewer and overland flow models, and the hydraulic head ...

  • A new methodology for surcharge risk management in urban areas (case study: Gonbad-e-Kavus city)

    This research presents a simulation-optimization model for urban flood mitigation integrating Non-dominated Sorting Genetic Algorithm (NSGA-II) with Storm Water Management Model (SWMM) hydraulic model under a curve number-based hydrologic model of low impact development technologies in Gonbad-e-Kavus, a small city in the north of Iran. In the developed model, the best performance of the system ...
