16 | GRUNDFOS SPECIAL 10 years will see innovation and technology go in a very different direction. While intelligent technology is already being used to conduct pre-emptive and predictive maintenance, according to Dr Gao, the pace will be really picking up over the coming five to 10 years, with pieces such as smart shower devices becoming a mainstay. “In the face of growing water demand amidst rapid urbanisation, we expect the water industry to greatly increase their adoption of intelligent technology in ‘smart cities.” Dr Gao continued. “Intelligent technology will play a key role in establishing interconnectivity across a city’s water management systems, applying advanced analytics to spot trends and patterns, as well as make predictions ranging from weather alerts to adapting water pressure based on reported water usage data.” ENDEAVOURS While there are increased efforts to control and remedy issues such as water pollution, regular monitoring of water sources is also vital — though access to the necessary technology may be limited in some parts of the world. But because water is such a vital part of infrastructure, the industry has made great strides in switching to newer technologies, though adoption remains slow and in Dr Gao’s opinion, companies need to do more to ensure they limit their impact on the environment as much as possible. “What companies need to realise is that while advanced intelligent technology can cost more upfront, the benefits in the long run will exceed the upfront investment,” Dr Gao elaborated. “As these innovations are further developed on a larger scale and with affordable distribution, cost will be less of a barrier, and it is valuable to establish strong cases through good quality pilot projects to demonstrate the innovative features to increase the acceptance level.” Water security is another critical issue the world is facing, with countries like Singapore focusing on alternative water sources such as water reuse and desalination, with Dr Gao predicting that water reuse will eventually be essential to meet global demand “especially when approaches like water use efficiency and consumption reductions are maximised.” NEW TECHNOLOGIES The rapid industrialisation the water industry is still undergoing has revealed an ever-widening gap in technology between countries, and, ever committed to their corporate social responsibility, Grundfos concentrated their efforts on closing the technological gap. “On top of that, the current wastewater treatment and management methods are highly energy-intensive as they undermine water movement and treatment throughout the production process,” added Dr Gao. To that end, the company developed BACMON, an intelligent, automatic microscope-based 3D scanning optics for monitoring bacteria real-time in the field. The patented solution classifies all particles as bacteria or nonbacteria by automatically moving a digital microscope over a flow cell. Grundfos is also working together with PUB, Singapore’s National Water Agency, to innovate new solutions in water treatment, water quality monitoring, efficient pump solutions and digital water solutions. “During our partnership, we tested Cake Filtration, a new wastewater treatment concept that used sludge generated from the treatment process to filter the wastewater, with BACMON++, a solution that offers online monitoring of total bacteria concentration in near real-time, improving bacterial monitoring of the water network,” he said. “At the same time, we are working on innovative pump-based solutions to optimise the water treatment process for both cost saving and energy efficiency, especially on the membrane filtration process. We have successfully piloted the solutions in Europe and are looking forward to leveraging these experiences to solve water challenges in Singapore.” Moreover, with most of the operational cost of water coming from the energy needed to move the resource — pumps alone are responsible for a staggering 10 per cent of global electricity consumption — and other costs incurred from water lost during the process, such as through leakages in the system. “One key solution is Grundfos’ Demand Driven Distribution, an intelligent water management pumping solution that automatically adjusts water flow through the use of remote sensors and reduces excessive pressure in the water pipes, minimising energy used throughout the day and also limiting water leakages and losses to drives down costs,” Dr Gao continued. “To date, Demand Driven Distribution has helped countless cities address this issue, such as tackling extensive leakage issues for water authorities while ensuring minimal disruption to citizens.” THE FUTURE According to Dr Gao, digitisation is the call for future water technology developments, with digital solutions such as big data and analytics able to guide operations on-ground and even enabling autonomous operations in the future. “As systems get more and more complex, the water industry can benefit from data-based technology to ease decision-making,” he concluded. “Digitisation also provides an effective way to stimulate customer problems and test solutions at controllable costs. It paves the way for new business models that can balance both sustainability and profitable growth.” WWA All images are credited to Grundfos. Water & Wastewater Asia • May / June 2019
MYANMAR WATER PORTAL | 17 Working towards a Resilient Yangon, uncovering the water needs and challenges in Thaketa township Since October 2018 a coalition of Dutch water organisations has been working together in the ‘Urban Water Logistics for a Greater Yangon’ (UWLY) programme to support the Yangon Regional Government in Urban Water and Water Logistics Challenges. Set to run for three years as part of the Dutch government’s “Partners in Business” (PIB) programme, the UWLY programme’s first deliverable is to present a scoping study. The study should provide locally grounded, inspirational and practical insight into what a water-resilient Yangon could look like at a township level. Upon request of the Yangon Regional Government the selected township was Thaketa, located east from central and downtown Yangon. PREPARATIONS FOR THE SCOPING OF YANGON AS WATER RESILIENT CITY As part of the scoping study, the team undertook several activities to gain a better understanding of the local water conditions in the Thaketa township. Several consultation sessions were held with the Yangon City and Regional Government and the Yangon City Development Committee (YCDC) to get a better understanding how the Thaketa township is governed, and what the local challenges are to ensure efficient water management. In addition to this, several preparatory consultations took place with local stakeholders in the township. Based on this initial analysis a field visit to Thaketa was planned. From 4 to 8 March, eight experts from different organisations of the consortium visited Yangon to get a feel for the issues and opportunities. Representatives from the Dutch Embassy in Yangon, Witteveen+Bos, Royal HaskoningDHV, U Minds, Doh Eain, Resilience and The Water Agency visited the township for two days and presented Variation in how the water reaches the houses their initial observations afterwards. The objective of the trip was to perform an urban water needs assessment of local stakeholders in the Thaketa township. The aim was for the delegation to get a good understanding of the area, visit the township for observations and consultations with citizens, business owners, local authorities, etc. to serve as input for the Resilient Yangon Scoping Study. After initial introductions and prioritisation, the delegation had its first field day on March 5, visiting several wards in the township. With great support and guidance of the YCDC Thaketa team and the local Ward officers, the delegations visited several locations where water issues were known to arise. In the afternoon the focus was on Ward 5, which is a ward that is isolated from the water pipeline network. It served as a great showcase for the experts to learn more on innovate ways of water supply. With the support of Ward 5 Officer U Tin Htun Aung a public consultation session was organised, inviting local inhabitants to share about their struggles and experiences with water in the ward. On the second field day there was a specific focus on Ward 7, walking through the ward and meeting with several inhabitants. Some observations from the field trip: Variation in the how the water reaches the houses The water supply in Thaketa was seen to be varied, and where ward 7 was well connected to the YCDC pipeline, ward 5 inhabitants were dependent on their own water supply. The coalition’s experts identified several ways of getting water to the homes: from the pipeline, the lake, the tubewell or through buying bottled water. THE STRUGGLE TO KEEP THE DRAINAGE CLEAN All over the wards small drainage canals exist that lead to main outlets in either the Bago river or the Panzundaung creek. Experts found that despite a waste collection system in place, many of the drainage canals are blocked. Both Ward officers shared their struggles to keep the canals free, having to perform manual maintenance at least three times in the year. Especially before the start of the rainy season there is a high urgency to clean up, as clogged drainage will lead to flooding of the streets. What was remarkable was that the team learned, through conversations with inhabitants, that there were variations in what people considered as flooding – flooding issues that the team felt would be areas of concern were not mentioned by the people they spoke to, and to the locals a flood was only when water stayed in the streets for multiple hours. The observations and initial analysis of the Field Trip were shared to the YCDC in a presentation on the final day of the Field Trip, also serving verification purposes. The next step in the Urban Water programme will be to deliver the Scoping Study. Based on the observations, consultations and findings of this visit, a scoping of Yangon as a Water Resilient City will be prepared together with ambitions and tangible objectives. The UWLY programme will be expected to organise a workshop in summer this year, for all stakeholders to present and discuss the way forward. WWA Drawing and photo credits to Flore Bijker.
