As far back as the 1960s, automated systems have been put in place to: reduce manpower requirements; decrease costs through the precise control of operations; maintain continuous monitoring and control of processes; initiate malfunction warnings; accurately react to system inconsistencies and observe operations from a central location. Automated processes have long been utilised by the water sector for functions such as turning a pump on and off under preset conditions such as pressure or water level, analysing chlorine residual in plant effluent or operating a complete system from a distant location. Telemetry, the language used by machines when "talking" with each other, was used in conjunction with automated systems to transmit information to a central location far removed from the actual operation. While telemetry systems are still utilised to perform similar functions today, wireless technological advances have transformed the way telemetry is used to remotely control, measure, monitor and transfer data from sites often dispersed over a wide area or based in difficult to access locations. Case study: Remote controlled sewer systems South East Water is one of Melbourne's three providers of water, sewerage, trade waste and water saving services. The Victorian Government-owned water retailer services over a million residential and business customers in an area spanning the South East of Melbourne to South Gippsland. With an increasing number of properties requiring a reliable pumped sewer system in areas where traditional gravity methods are not feasible, South East Water faced the challenge of remotely monitoring and controlling pressure sewer stations located throughout backlog areas in Victoria without access to fixed-line infrastructure. As part of an ongoing commitment to change and improvement, South East Water's SCADA Manager, Andrew Forster- Knight, approached NetComm Wireless to discuss the deployment of a customised wireless communications solution designed to pass data from the sewer stations back to the SCADA host system over the Internet. Following a thorough screening process, a high-speed HSPA M2M Router was selected to develop wide area networks utilising the flexibility of 3G. Designed to support remote installation and exposure to harsh environments, NetComm Wireless' HSPA M2M Routers support point- to-point or point-to-multipoint communications in mountainous terrains, high water table districts, environmentally sensitive regions, high gravity zones and other areas typically serviced by pressure sewers. With the need for constant network surveillance and regulation to ensure a reliable solution for customers, South East Water required a heavy-duty router designed to support multi-level system monitoring for undisrupted communications. "We chose NetComm Wireless as they had the experience and flexibility to tailor their technology to meet our needs now and in the future. We have found the device to be extremely robust in design and operations," says Andrew Forster- Knight, South East Water. "The device underpins the Touchpoint technology used by South East Water to enable proactive monitoring and predictive control of the pressure sewer networks and related infrastructure. Over time the benefits realised will be huge, thanks to the innovative solution involving NetComm Wireless' products." FAMILIAR TREATMENT PLANT FOUR TROUBLES Which do you want to overcome?
