Wireless data collection options for GaugerGSM
Wireless data collection options for GaugerGSM GaugerGSM is an ultrasonic level meter with wireless GSM communication capabilities. GaugerGSM sends both periodic messages and event messages. Periodic messages are transmitted once in a period of time. The period is predetermined and fixed. In some cased, several periods of time may be defined and the rate of sending messages will be dependent on ...

Efficiency of a turbidity-based, real-time control strategy applied to a retention tank: a simulation study
This paper compares several real-time control (RTC) strategies for a generic configuration consisting of a storage tank with two overflow facilities. Two of the strategies only make use of flow rate data, while the third also introduces turbidity data in order to exercise dynamic control between two overflow locations. The efficiency of each strategy is compared over a wide range of system ...

Sewer Level Monitoring - Photos
Sewer Level Monitoring - Photos Photos in this article present the complexity and versatility of sewer level monitoring. When examining the photos, pay special attention to the stand-alone autonomous characteristics of each installation. In lack of any cabling from the outside, whether data cables or power cables, the solution is fed from its own battery power supply. Data is tranmitted over the ...

Evaluating the success of sewer reconstruction by using carbamazepine as anthropogenic marker in groundwater
The antiepileptic drug carbamazepine is a useful anthropogenic marker in groundwater to detect and quantify sewer exfiltration. In 2003 its application on a city wide scale enabled the identification of a trunk sewer in extremely bad structural status with an exfiltration (of wastewater into groundwater) rate in the adjacent area of around 5% compared to an average of approximately 1% in other ...

Municipal sewer remote monitoring
Sewers are critical heavy duty infrastructure components requiring costly maintenance. Many municipalities suffer from ageing pipelines that pose higher chances of failure. Sewer leak or overflow results in high cost as a result of civil reimbursement and due to inflected illness. Moreover Civilian frustration that results form the overflow is often targeted towards the municipality. Overflow can ...

Sewer Level Monitoring System - a case study
Background - The business of sewage level monitoring in sewers is accelerating across many countries. Strict regulations, the need to avoid environmental disasters, violation fines, early warnings and planning needs are just some of the forces shaping this growing trend. Challenges Quantifying sewage flow and level is one of the most challenging engineering tasks for the instrumentation ...

From mess to mass: a methodology for calculating storm event pollutant loads with their uncertainties, from continuous raw data time series
With the increasing implementation of continuous monitoring of both discharge and water quality in sewer systems, large data bases are now available. In order to manage large amounts of data and calculate various variables and indicators of interest it is necessary to apply automated methods for data processing. This paper deals with the processing of short time step turbidity time series to ...

The sewer system, an undervalued place, that we depend on every day
How Digitizing the Sewer supports Climate Change A good infrastructure, such as our sewer system, is essential for a vital, viable, sustainable and social development of a country’s economy. Not only does it play an important role in sanitation and disease prevention, but the sewer system also plays a crucial role in the sustainability of our planet and the future of our generations . Due ...

Performance assessment of separate and combined sewer systems in metropolitan areas in southern China
To assess the performance of urban drainage systems in metropolitan areas in southern China, 12 urban drainage systems, including nine separate sewer systems (SSSs) and three combined sewer systems (CSSs) were monitored from 2008 to 2012 in Shanghai and Hefei. Illicit connection rates of SSS were determined. The results indicate that serious illicit connections exist for most SSSs. Annual ...

Evaluation of effectiveness of combined sewer overflow control measures by operational data
The effect of combined sewer overflow (CSO) control measures should be validated during operation based on monitoring of CSO activity and subsequent comparison with (legal) requirements. However, most CSO monitoring programs have been started only recently and therefore no long-term data is available for reliable efficiency control. A method is proposed that focuses on rainfall data for ...

Combined Sewer Level (CSO) Monitoring and Analytics - Case study
Our CSO Monitoring solutions combines MAP Rain and machine learning to compare the historic performance of assets with historic rainfall. We then use this analytis to deliver actionable insights that predict the operation of the CSO, or other similar geometries in MAP, to current and forecast rainfall. Key features Three different modes of operation Rainfall. Expected operation is driven ...

Coupling acoustic devices for monitoring combined sewer network sediment deposits
Combined sewer networks display some unique features that are not easily reproducible in the laboratory and have yet to be well understood. The transport of organic and mobile sediments, present in large quantities despite the use of optimal design practices, dramatically changes sewer flow patterns and the interaction between flow and sediment. To understand both the flow patterns and ...

CSO management from an operator's perspective: a step-wise action plan
Combined sewer overflows (CSO) are the “ugly ducklings” of urban wastewater infrastructure, rather unknown, rarely loved. Contrary to wastewater treatment plants (WWTP) where, commonly, process parameters are carefully registered, still relatively little is known about the spill behaviour of CSOs. In spite of the considerable bandwidth of pollution magnitude reported in literature, it can be ...

Flow measurements in sewers based on image analysis: automatic flow velocity algorithm
Discharges of combined sewer overflows (CSOs) and stormwater are recognized as an important source of environmental contamination. However, the harsh sewer environment and particular hydraulic conditions during rain events reduce the reliability of traditional flow measurement probes. An in situ system for sewer water flow monitoring based on video images was evaluated. Algorithms to determine ...

Enhancing Sewer System Monitoring with Remote Radar Level Sensor
A utility company identified the need for real-time remote monitoring of water levels in their sewer system to prevent overflow incidents, optimize maintenance efforts and enhance the overall efficiency of their sewer system management. Challenge Traditional methods of monitoring sewer water levels are cumbersome and lack real-time capabilities. Alternative real-time solutions tested proved ...

Model evaluation of faecal contamination in coastal areas affected by urban rivers receiving combined sewer overflows
Odaiba seaside park is one of the most popular waterfronts in Tokyo Bay, but is easily affected by wet weather pollutant loads through combined sewer overflows (CSOs). The monitoring data of Escherichia coli clearly showed high faecal contamination after a rainfall event on 9–11 November 2007. We estimated the amounts of discharge volume and E. coli pollutant loads of urban rivers ...

Good Preparation and Planning Reduces Wastewater Headaches Associated with Production Outages
Author’s note: The terms mill and plant are used interchangeably in this article to describe an industrial manufacturing unit, such as a Pulp & Paper Mill, Petroleum Refinery, Chemical Processing Plant, Meat & Poultry Processing, etc. Plant (or mill) outages come in two types – scheduled and unplanned. Scheduled outages are generally annual affairs at roughly the same time ...
