Water & Wastewater Asia May/Jun 2019

Water & Wastewater Asia • May / June 2019 12 | GRUNDFOS SPECIAL Grundfos recently launched its prefabricated pumping station (PPS), which optimises pumping station design and operation - a vast improvement to traditional pumping stations W ith countries around the globe suffering from the impacts of water scarcity, it is at the top of every national agenda. Closer to home, nearly two billion people in the Asia Pacific region have poor or limited accessibility to water, and the number is expected to reach five billion by 2050. The crisis is exacerbated by the deteriorating quality of the water, with 90 per cent of the total wastewater generated in the region being mixed with the freshwater system without adequate treatment 1 . Amid the rapid industrialisation and urbanisation seen across the region, the existing water infrastructure is playing catch- up in treating the increasing wastewater that comes with economic development. Preserving water quality and ensuring the water resources available are clean and safe to use is indispensable in our efforts By Leong Chee Khuan, Area Managing Director for South Asia and General Manager for Grundfos Pumps Sdn Bhd to ensure water security. The lack of proper wastewater management intensifies the crisis and results in massive health costs. Proper drainage and disposal of wastewater is also crucial to protect the environment and combat extreme weather events such as floods through removal of rainwater. Therefore, wastewater management is also central to building a sustainable future. The impact of wastewater treatment on the ecosystem and human health makes wastewater infrastructure a crucial component of economic development and sustainability goals. Even as countries are developing projects in the wastewater sector, there is scope to do more to ramp up the region’s drive towards sustainability. Deploying innovative and adaptable solutions that enhance efficiency in wastewater management and optimise the treatment processes will be crucial in attaining these goals. TAPPING INTO THE PRIVATE SECTOR’S EXPERTISE Effective management of wastewater calls for aligned efforts from both the public and private sectors. While governments shoulder the responsibility to ensure water quality for citizens, industry players are also responsible for introducing innovative solutions given their expertise in the water sector. A case in point is Malaysia. With Malaysians currently producing an estimated 5.1 million cubic metres of sewage daily – the equivalent of 2,000 Olympic-sized swimming pools 2 – sustainable wastewater management is one of Malaysia’s key focus areas for effective water governance. The government is planning to build 77 sewage treatment plants nationwide by 2040 under the National Sewerage Catchment Strategy. A key part of the wastewater management process is pumping stations that collect and transport wastewater. However, traditional pumping stations are made of concrete casted on-site, which not only means greater time spent on construction and detailed planning, but also susceptibility to chemical corrosion and subsequent leakage over time. They also occupy a lot of space, which is an issue for the rapidly urbanising country. Industry players such as Grundfos are complementing the government’s efforts by introducing new technologies to address the country’s unique challenges in wastewater treatment. Given that pumping stations are central to modern environmentally-friendly processes in wastewater treatment, the company recently launched its prefabricated pumping station, which has been developed
