Water Network Monitoring Solutions Helps Save 1.5 Million Litres of Water a Day
Effluent Sampling Allowed Under MCERTS Scheme
Environmental monitoring specialist, enitial (UK), has become one of the few sampling companies in the UK allowed to deliver effluent sampling under the Environment Agency’s monitoring certifications scheme (MCERTS).
The United Kingdom Accreditation Service (UKAS) awards the MCERTS standard to organisations who can prove they are able to provide a consistently high quality sampling service, giving the Environment Agency confidence in their sampling of untreated and treated sewage effluents and trade effluents.
Ivor Parry, business development director at enitial said: “enitial is always striving to provide a high quality service. Receiving this accreditation means our technicians can deliver monitoring services to water utility sites that are subject to permits requiring Operator Self Monitoring (OSM). It’s a requirement for many water companies as the Environment Agency uses the results to determine how well a company complies with its permit conditions.”
After an extensive audit, enitial was awarded accreditation to ISO/IES 17025:2005 and the Environment Agency’s MCERTS Performance Standard for organisations undertaking sampling and chemical testing of water for the sampling of untreated and treated sewage effluents and trade effluents.

i2O Water (UK), a provider of water network monitoring solutions, announces that it has helped Veolia Water realise savings in excess of 1.5 million litres of water a day, nearly £100,000 a year, and improve customer service, following a successful roll out of i2O Water’s integrated network monitoring system across 31 Veolia Water sites in the UK.
Veolia Water approached i2O in August 2010, following very large and unpredictable demand it was experiencing at a golf club during golf tournaments and periods of dry weather in the surrounding areas. During these times, when demand increased significantly, Veolia Water needed to supply much higher quantities of water to the area to address demands from the golf course, which in turn had the effect of lowering the pressure of the available water in the network. Unless Veolia Water could actively manage and control the pressure to address this fluctuating demand, it was either going to provide poor customer service or risk running the pressure too high, resulting in high leakage and water bursts.
To help solve this problem, Veolia Water installed i2O’s integrated network management system and was able to remotely reduce burst mains and leakage and improve response to network issues. The solution provides the ability to proactively control and optimise the water pressure, which helps Veolia Water optimise the management of its network. The reduction of background water leakage on the first system alone was estimated at 300,000 litres a day following installation and optimisation, and proved such a success that Veolia immediately rolled out the i2O technology into another 30 areas by the end of 2010. This has resulted in a leakage reduction of 1,500,000 litres of water a day – nearly enough water to fill an Olympic swimming pool each day.
Stephen Eeles, Leakage and Network Operations Manager at Veolia Water said: “The implementation of the i2O solution has enabled us to proactively address pressure management issues across the Veolia Water network, enabling us to focus on problem hotspots where we were seeing supply issues due to demand spikes. This has enabled us to realise significant water and cost savings and, importantly, improve the service we are able to offer our customers.”
Adam Kingdon, co-founder and CEO of i2O Water commented: “We are extremely excited to be working with Veolia Water to help it better manage pressure in its water network. The i2O solution involves deploying smart pressure controllers and sensors into the water network that allow remote monitoring and control of water pressure, ultimately reducing water leakage and bursts. The technology has been installed at water companies globally with excellent results, consistently cutting leakage and energy use by an average of 20% and reducing new bursts by up to 50%. It also has proven to be easy to deploy and easy to use.”
There is a perception that water shortages mostly affect developing nations, but increasingly developed nations are feeling the effects. Recently the United Nations World Water Development Report advised that water shortages are already constraining economic growth in California, China, Australia and India. Presently in the UK, it is estimated that around 3.3 billion litres of water are wasted every day through leakage.

Traditionally, the water industry uses turbine type meters for large commercial revenue and district metering. This technology has remained largely unchanged for many years and whilst these meters have provided an invaluable service to the industry, they are not without problems, such as wear, leading to under-registration of flow, impacting on revenue and leakage estimates, particularly at low flows.
Battery powered electromagnetic and ultrasonic meters are now challenging the traditional meters by claiming new benefits and better performance. The mechanical meter manufacturers though are fighting back with new models that also claim improved performance levels and incorporate the benefits of electronics such as integrated communications.
So what is the water company looking to invest in upgrading or replacing its large revenue and district meter stock to make of these claims? These are important applications. Commercial revenue meters account for a significant proportion of water company income and differences in performance can be worth several thousands of pounds over the lifetime of the meter. Leakage remains a hot issue with much of the UK in a drought; reliable and accurate flow data is critical to leakage estimation and targeting repair activities. Informed meter selection is, therefore, essential to company performance.
WRc (UK) has recently started a collaborative project with four UK water companies to evaluate the “next generation” of large water flowmeters – both mechanical and electronic types. This project will test the claims being made for these new meters through an extended, rigorous and independent test programme.
The results will be invaluable to water utilities planning future investment in large meters. It will identify the levels of performance likely to be seen in service, how to get the best performance from these meters and the implications of moving from the present meters to the next generation.

Plans to Offer Largest Range of MCERTS Water Quality Monitors
A massive programme of MCERTS testing is underway for many of Hach Lange’s (UK) market leading water quality monitoring instruments. UK Sales Director, Matthew Dillon says “Most of the instruments are already in widespread use across a broad range of industries, but as the Environment Agency increasingly requires the use of MCERTS approved analytical equipment, our intention is to be able to offer customers the greatest possible choice of certified instrumentation.”
MCERTS is the Environment Agency's Monitoring Certification Scheme and was established to provide a framework for businesses to meet prescribed quality requirements. The Agency’s Paul Wiggins has applauded Hach Lange’s commitment to the MCERTS scheme, adding “We are gradually moving to a position in which the operators of regulated processes will only be allowed to use MCERTS approved equipment for compliance monitoring, so this represents a window of opportunity for manufacturers with instrumentation that is able to meet the required standards.”
Hach Lange already has MCERTS approval for a range of water samplers, but the latest sets of instruments to undergo MCERTS testing cover both portable and fixed water quality monitors. The online monitors undergoing testing include the Biotector TOC Analyser, and the SC1000 Digital Controller with sensors for pH, dissolved oxygen, ammonium and turbidity.
The portable devices currently undergoing tests include the HQD instrument with Intellical electrodes for pH, conductivity and dissolved oxygen.
