new products & services 92 JULY 2012 water water business rapidly varying flow rate and water quality. A final complication was that of environmental requirements. At times the VH plant carries out environmental discharges and this discharge must contain no chlorine. Thus, a new solution was required. A multi-criteria analysis was conducted with the major stakeholders as a tool to aid in determination of the optimal solution. The chosen solution was to upgrade the inlet pump station (PS-1) to incorporate upstream balancing storage, upgrade the plant aeration system to better remove ammonia, move the chlorination point to a location with a stable flow rate (post a 5ML treated wastewater balancing storage) and construct a new 5ML storage lagoon, to contain the treated wastewater and supply reuse customers by means of a gravity network. These upgrades are scheduled for completion in December 2010, with a one-month commissioning and optimisation period carried out in January 2011. CELEBRATING 50 YEARS OF DUCTILE IRON PIPE MANUFACTURE Tyco Water's Yennora facility has just celebrated half-a-century of operations to commemorate the enduring success of the last surviving ductile iron pipe manufacturing facility in Australia. Dignitaries and customers were joined by past and present employees for the celebration, at which guests were entertained with stories of days gone by and a band playing 50 years of hits from 1962 to the present day. The Yennora plant was commissioned on 29 May 1962 and originally began producing centrifugally cast grey iron pipes. The plant converted to ductile iron in 1978 to deliver stronger, yet lighter pipes to the Australian water industry. During its 50 years of operation, the plant has also been a significant contributor to the local, state and national economies. General Manager, Wayne Evans, noted that "the plant's economic contributions amounting to tens of millions of dollars each year stem not only from its vital pipe output, but also from procurement of raw materials, power, gas, water and other services from local suppliers, payment of local taxes and the provision of employment. Since opening in 1962 the plant has provided jobs to thousands of people, mostly residents of the western Sydney community." The plant is also a major recycler of scrap and waste steel, processing more than 2.5 million tonnes. The recycled waste has been used to produce in excess of 55,000 kilometres of vital water pipelines used across Australia and around the world. THE SYSTEM WITH THE "NO LEAK SOLUTION" Link-Seal® Modular Seals are a positive hydrostatic seal which seal the annular space and are considered to be the premier method for permanently sealing pipes of any size passing through walls, floors and ceilings. For more than 15 years, Projex Group has been working with designers, engineers, project managers and contractors to permanently seal pipes of any size. Link-Seals have been successfully installed in water and waste treatment plants, oil refineries, gas plants, hospitals, and sewage plants, Link-Seals are robust and are specially formulated to withstand attack from ozone, sunlight, water and a wide range of chemicals. They can handle slight movement and extreme temperatures (-50--120°C), provide maximum protection against corrosion and can hold up to 20psig (12 metres of static head) pressure. They are available for a wide variety of special applications, temperature extremes, exotic chemical combinations and for slightly "out of round" or non-centred applications. Benefits include: • Suitable for potable water; • Saves time & money; • Positive hydrostatic seal; • Long seal life; • Maximum protection against corrosion; • Mechanical seal -- can be refitted; • Maintenance-free after installation; • Easily installed by one person.

Until last year the plant was used to filter potable water for the township of Meredith in central Victoria. Changes to the configuration of the regions water supply system has meant the filtration unit is no longer required. Filtration capacity is approx. 30 litres/second (net).
