Water Leakage Cuts in Malaysia


Clamp-On Flow & Heat Meters to Monitor and Improve Water and Energy Saving Projects


Monitoring the performance of water and energy saving initiatives is essential to demonstrate the benefits, ensuring that systems operate to specification and are tuned for maximum savings to deliver fast pay-back on investments. And London based PA Energy who specialise in the supply, installation and ongoing monitoring of turnkey sub-metering systems have used Micronics (UK) ultrasonic clamp-on flow and heat metering products to good effect on a wide range of water and or energy saving projects.


The projects have included rainwater harvesting, fuel cell and solar/thermal installations on commercial buildings in the London area and the simple clamp-on, non-invasive solutions from Micronics have offered significant advantages over the traditional alternative of in-line meters and their requirement for system drain-down, pipe cutting, re-filling systems and the associated costs, which are all avoided by the use of a clamp-on solution.


i2O Water’s (UK) technology to reduce water leakage is making a massive difference to water supplies in Malaysia. i2O Water is helping SYABAS, Malaysia’s largest water utility company, to save 40 million litres of water per day in the state of Selangor - enough to provide water for 180,000 people. So far, i2O Water, provider of new technology for monitoring and controlling water networks, has installed more than 200 of its innovative pressure management systems across SYABAS’s water distribution network.


SYABAS is the largest water company in Malaysia. It supplies water to 7.3 million people across the state of Selangor and the federal territories of Kuala Lumpur and Putrajaya. As well as reducing leakage and saving massive amounts of water per day, i2O Water has also helped to reduce pipe bursts by 40%. In turn, this has substantially reduced the disruption caused by roads being dug up to find leaks and repair burst mains, thereby reducing companies’ operating expenses. It has also cut energy costs and improved levels of customer service.


Sheikh Mazlan Sheikh Hassan, managing director of Jalur Cahaya Sdn Bhd, said: “We are always looking for new technology to assist in non revenue water reduction works and our investment in 200 i2O systems since April 2010 has given us 40 MLD (megalitres per day) additional leakage savings to date. The i2O systems are also helping us to reduce our operating cost in terms of leak repairs by as much as 40%.”


The World Bank estimates that every year a staggering 32 billion cubic metres of treated water are lost from urban water supplies around the world. In the developing world, the average non revenue water loss approaches 50% of the water actually produced. Any significant reduction in this figure could give millions more people access to clean running water.

Aquamatic Limited (UK), manufacturer of automatic wastewater samplers, has supplied Tulip Limited with a new MCERTS Certified Aquacell S100 auto-sampler for use at its new multi million pound state-of-the-art sausage production facility in Bromborough, England.


Tulip Limited approached Aquamatic for the supply of an automatic wastewater sampler which would allow them to accurately and continuously collect and store samples volumes from their on-site effluent treatment plant, prior to laboratory analysis. These samples would then be assessed to ensure compliance with Tulips environmental discharge consent.


Chris Davies, Tulip Limited Site Services Manager, commented “As a company Tulip takes its environmental responsibilities extremely seriously, and effective wastewater treatment is a critical process at the factory. Reliability, value, ease of use, after- sales backup, and compliance with the Environment Agency MCERTS standard were all factors considered when choosing an Aquamatic auto-sampler for our flagship site.”


In addition to the supply of the Aquacell S100 sampler, Aquamatic also provide Tulip Ltd with an on-site maintenance contract to ensure hassle-free operation for years to come.

Palintest (UK) is launching the new Macro 900 Water Quality System for multiparameter water quality monitoring. Designed to combine portable hi-tech functionality with excellent ergonomics in an easy-to-use package, the Macro 900 WQS is particularly well-suited for environmental surveys, aquaculture applications and wastewater and surface water monitoring.


The Macro 900 Meter forms the core of the system. It is completely waterproof, battery-powered and includes three dimensional GPS positioning as standard, storing up to 1900 full data sets of results. The high-contrast LCD screen is backlit for use in low light environments and the rubberised function keys are designed for effective use even with wet or gloved hands.


A full range of Macro Accessory Probes allow the system to monitor a wide variety of parameters, including: pH, conductivity, TDS, turbidity, depth and both optical and galvanic Dissolved Oxygen (automatically compensated for atmospheric pressure and salinity). All Macro Accessory Probes are simple to maintain, manufactured in marine grade aluminium and only 48mm in diameter to ease use in narrow boreholes.


In addition to the Meter and Probes, the Macro 900 Water Quality System comes complete with a full range of accessories and consumables, including: extension cables for the Probes, flow cells, MacroLink software, calibration solutions and replacement probes/caps.

For the rainwater harvesting project a claim for a reduction in the sewage charge is being developed by using a Micronics U3000 to demonstrate how much rainwater is being dumped to sewage by metering the amount of water being pumped into a grey water tank in comparison to the boosted cooling water entering the tank. Another application was measuring the LTHW heat flow from a fuel cell calorifier again with a U3000 to demonstrate the performance of the fuel cell process. And yet another was monitoring the heat transfer/performance from a solar/thermal panel by measuring the water /glycol mix and differential flow and return temperature with a heat calculator to calculate heat transfer to the buffer vessel heat exchanger to demonstrate the performance of the solar/thermal system i.e. that it was performing to specification.


PA Energy selected clamp-on ultrasonic flow meters for the clear advantages of being low cost, non disruptive and simple to install in comparison to in-line meters and Micronics were selected as the supplier due to a combination of their long-term experience with non- invasive, clamp-on technology, product performance and pre-order assistance.

Belated Plans by Thames Water to Move Water from West of Britain Welcomed


GMB(UK) have welcome belated plans by Thames Water to move water from west of Britain as south east and east of England households face hose pipe ban.


There is no shortage of water in Britain but there is a shortage of structures that can make decisions to get the water to where it is needed and this is a small step in the right direction but comes too late to help consumers says GMB. GMB, the water workers union, commented on reports that 20 million people in the South East and East of England will face a hose pipe ban within the next few weeks and on a statement by Thames Water that they will move water from the west of Britain.


GMB has consistently said that there is no shortage of water in Britain only a lack of capacity to get the water from where it is plentiful to areas where it is scarce. GMB’s position has been ignored by water companies and the government until now. No plans have been made to increase the supply of water to the South East and East of England until now which is too late to solve the problem and avoid the ban. The media reports; Thames Water says it’s considering using water from the River Severn to supply London in the event of a drought this summer. The company which supplies 8 million homes in and around the capital is also looking at restoring disused canals to transport the water, spokesman Richard Aylard says that will be a lot cheaper than laying new pipes.


The government’s White Paper on water supply called for the introduction of a ‘market’ for water for households. GMB dismissed this as irrelevant and called on all concerned to recognise that water is a natural monopoly. In 2006 GMB put back on the table plans from the former Water Resources Board to import water from the west of Britain to those parts where it is scarce. GMB also published a paper dated 18th November 2011 by Barry Rydz, a retired official of the old Water Resources Board, which sets out again the case for water to be transferred from the west of Britain to the South East and Eastern England and identifies a number of ways of doing this.
