African Trial for Remote Water Monitoring System


Severn Trent Supplied with Wastewater Monitoring Systems


Multi-utility monitoring and telemetry specialist HWM, in partnership with field services expert Enviromontel, has won a contract to supply, install and maintain fixed-point sewer network monitoring equipment for Severn Trent (ST).


In what is thought to be the largest project of its kind, ST is targeting better monitoring of its wastewater networks in order to improve performance and customer service, as well as reduce flooding and pollution incidents.


Following a rigorous evaluation process, ST decided that HWM offered the greatest overall value and was best able to help ST achieve its strategic objectives. HWM is due to provide three separate products over a five-year period, all based on the company’s new Intelligens data logger: 700 Intelligens Flow monitoring systems, capable of recording


parameters such as velocity and depth, 3,000 Intelligens WW and SonicSens ultrasonic sensors, used to record the level of flow, and 1,130 Intelligens Flood Alarm systems, which register that the level in the sewer has risen beyond an acceptable height and transmit an alarm.


A new remote monitoring system to ensure rural communities have access to water is being trialled in Sierra Leone.


The technology – a collaboration between Leeds Beckett University researchers and two Yorkshire SMEs – monitors whether hand-operated water pumps are in regular use, to identify when pumps are broken and communities cut off from their water supplies.


A recent USAid report stated that up to 40 percent of rural water systems in sub-Saharan Africa are out of use, representing between $1.2-1.5 billion in lost investment. Fewer than five percent of water infrastructure projects are visited after installation, leading to broken pumps going undetected and unrepaired.


The MANTIS (Monitoring and Analytics to Improve Service) system, now being field tested on ten pumps in the Bumpe Ngao Chiefdom of Sierra Leone, is low cost and easily deployable. The system detects whether the pump is in regular use and reports patterns of usage. Its simplicity enables it to have an exceptionally long life-span compared to other remote monitoring systems under development. The technology has been designed to function for five years without maintenance or re-power, sending back daily data on hand pump usage for interrogation via an easily accessible web interface, which can be monitored by an NGO or government agency to ensure repairs are swiftly made.


Lead researcher Dr Andrew Swan explains: “Remote monitoring has a very practical purpose – to spot broken hand pumps quickly so they can be repaired and people can continue to get easy access to water, even in very isolated areas. But the ease at which the data can be accessed means that this technology can also improve transparency and accountability as to how development funds are spent and how effective they are. Funders – whether countries, NGOs or individuals – can also see whether the pumps they’ve paid for are working.


“There is currently only limited information on how many of the millions of hand pumps installed across the world are actually still doing their job and visiting each one regularly is really impractical given their hard-to-reach locations. Remote monitoring could really help towards putting more effective and efficient maintenance in place.”


The MANTIS system was developed by Dr Swan, working with two technology companies based in Sheffield: Environmental Monitoring Solutions Ltd (EMS), who specialise in water, wastewater and emissions monitoring; and VisualWind Ltd who develop software for the wind energy industry. The work has been funded through an Innovate UK grant, led by EMS. The system is specifically designed to fit the two most common designs that make up the majority of hand pumps installed worldwide, but is compatible with almost any hand pump.


Managing Director of EMS, Professor Pete Skipworth, said: “The MANTIS system relays daily usage information in compressed format and relays whether the hand pump is in use – which is often all that is needed to highlight when pumps are broken. Our simple approach reduces power requirements, which enables the system to function for longer, and also reduces its production costs.


“This initial trial will show us how our prototype system works in the field, enabling us to fine tune the technology before we


deploy it more widely.” For More Info, email: email:

The intrinsically-safe (ATEX Zone 0) Intelligens is housed in a rugged IP68 enclosure and fitted with a GPRS modem for remote monitoring and reprogramming. The unit’s advanced power management allows for over five years’ data collection and transmission under standard operating conditions. An alarm regime can be configured for each channel and threshold conditions set to trigger faster logging and accelerated data transmission during alarm conditions.


The data logger and associated interfaces are compatible with a variety of sensors including Doppler-effect velocity, hydrostatic depth, ultrasonic level, radar level and digital inputs from rain gauges or float alarms. This allows HMW to offer complete monitoring systems suitable for permanent or temporary flow surveys, level monitoring or flood level alarm. Typical applications for the equipment include foul, combined and storm water sewers, as well as adopted private sewer monitoring, but it can also be used for open channel or outflow monitoring.


The benefits of long-term monitoring in wastewater networks include a reduction in both the frequency and impact of pollution events. Permanent installation of remote monitoring equipment helps to alert network operators to immediate problem sites. It also improves understanding of network performance and delivers data to assist with the development and testing of advanced network models.


How to Specify the Best Flowmeter for your Application

Titan Enterprises reports on a white paper written to assist design engineers looking to specify the best liquid flowmeter for their application.


Choosing the best flowmeter for your application can be a daunting task as the optimal specification can vary considerably according to a wide range of operational parameters including pipe bore, flow path, liquid viscosity, particulate levels, measurement accuracy, measurement dynamic range, maintenance required and target purchase price.


Drawing upon over 40 years of designing and supplying liquid flowmeters to meet stringent specifications – the engineering team at Titan Enterprises produced an informative and unbiased white


paper that discusses the benefits, limitations and ease of applying different flowmeter technologies (differential pressure, turbine, propeller, positive displacement, vortex, ultrasonic, electromagnetic and mass flow measurement) to metering liquid flows. In addition the paper discusses the many elements that make up cost of ownership over and above the flowmeter purchase price that a design engineer should consider when specifying the best system for their application.


To assist the specification process the paper includes an easy-to-use selection guide that takes 13 different application examples and charts them against 14 different types of flowmeter, highlighting the good, the bad, and the questionable techniques for each application.


Titan Launches New Responsive Website

Dee Stapley, Sales Manager said, “The clean design of the new Titan website allows visitors to simply and quickly locate pertinent product information including the full technical specifications of our extensive range of ultrasonic, oval gear and turbine flowmeters as well as flow instrumentation. In response to customer demand we have produced a series of new selection charts which enables you to quickly select which Titan product is the optimum choice in terms of handling the fluid type, flow rate, maximum pressure and maximum temperature your application requires. In addition, visitors can quickly access service and support information, flow meter calibration services and find where their local sales agent is located. Located at www.flowmeters.co.uk the site is well worth bookmarking by anyone required to meter the flow of fluids”.
