Topic:Promoting the demand for refined water management in the water industry

Unusual extreme weather has caused severe floods and droughts all over the world in recent years. While facing the changing environments of frequent floods and drought, Taiwan’s government has implemented several proactive programs, which include “Forward-looking Infrastructure Development Program”, project of stabilizing water supply, technologies of smart management and water conservancy. The programs aim to build up a reliable and resilient water environment with no water shortage, with clean drinking water, with no flooding, and closing to water. As for water resources management, besides reclaimed water, rehabilitation of reservoirs, hydraulic de-silting and regional water source allocation and backup, the government also enlarges the implement area of water gates-control worker in Chianan regions to strengthen irrigational efficiency. The water consumption of the first stage of this year's paddy fields was only 8,700 tons per hectare, which is at the historical low. Furthermore, smart water management system is also developed for use water resources more effective by allocating water dynamically. As in the aspect of flood prevention, the law of runoff distribution and outflow regulation is approved by Legislative Yuan and a smart flood prevention network is built up to provide warning and decision-making support. In conclusions, Taiwan has learned and gained rich experiences from past disaster rehabilitation. The knowledge has been upgrading water technologies and refined management skills. At present, the advanced technologies such as hydraulic desilting of reservoir, reclaimed water, and smart disaster prevention, have attracted attentions from abroad. For advocating economic growth in Taiwan, the government has invested on the construction of water environment to continually support industry development and meanwhile expand the water industry into the global market, moving forward to the "Blue Ocean"

Topic:How to Create a Sponge City through Municipal Comprehensive Flooding Control Measures

In recent years, urban drainage in Taiwan has often faced the threat of heavy rain and extreme rainfall. In order to use forward-looking and effective strategy to face this serious challenge, the Construction and Planning Agency of Ministry of the Interior advocates the idea of municipal comprehensive flooding control measures to promote the construction of underwater waterways for the rain. It is hoped that a three-dimensional flood control strategy can create a resilient city where people can live with water and can revive after flooding quickly. This talk will start from the history and current situation of the construction of sewer systems in Taiwan, including the review on recent rainfall incidents and flooding disasters, the influences caused by outdated planning which is not in line with reality, the low implementation rate in some areas, the insufficiency of the past design basis, and bad maintenance management, the definition of flooding, and the city residents’ unrealistic expectations on the government caused by different perceptions of flooding. Immediately afterwards, I will explain the municipal comprehensive flooding control measures promoted by our agency, including the foundation of the municipal comprehensive flooding control technical service group, and innovations such as adopting GIS of sewer system, the introduction of low-impact development and the establishment of disaster prevention system. In the end, I will propose the future prospects of urban flooding control under the prospective construction, including comprehensively improving the urban flooding protection standard indicator and continuing to promote municipal comprehensive flooding control measures to create a sponge city.

題目:昂貴的引水地道能夠拯救曼谷脫離下一次劇烈的洪水嗎?

2011年遍布泰國的劇烈洪水在泰國當代歷史中被視為最嚴重的災禍。至於到底哪個環節出錯以及災禍成因都令人好奇,且尚無解答。雖然相關當局的解釋並不明確,然而,都有意減少曼谷洪水的風險。其中一項方法為在曼谷首府中心發展引水地道。此地道距離地面20公尺深,用以排出城市洪水。此一工程展現創新的洪水管理,令人耳目一新。第一條地道於2017年8月發展完成,且城市周邊正在興建更多龐大預算的地道。
這種預防洪水的計畫變得令人懷疑。人們對昂貴的投資爭辯不已,且有更多問題浮現。這是有效的防洪管理嗎?究竟需要多少條地道?確切來說,氣候變遷問題並沒有考慮到洪水不是自然現象,而是人為造成的。在一方面,大多數防洪項目多年來都沒有實行,這是無法否認的;更甚者,在2011年的洪水災害後曼谷的環境建設有了巨大改變。修改一些數據和訊息並全面討論此防洪計畫是挺有意思的。但最嚴肅的問題是:引水地道計畫能夠拯救曼谷脫離下一次劇烈的洪水嗎? 即將到來的季風季或許正是證明它的時刻。

Topic:Can the costly diversion tunnel save Bangkok from the next great flood?

The severe flood throughout Thailand in 2011 is viewed as the greatest disaster in the modern Thai history. What went wrong and why it happened remain curious questions without answers. Despite unclear explanation from the involved authorities, however, attempts are being made to reduce flood risk in Bangkok. One of those attempts is the development of diversion tunnel in the inner core of Bangkok metropolis. The tunnel is 20 metres beneath the ground which was designed for draining flood water out of the city. It is considered shortly as an impressive engineering project showing the innovation of flood management. The first tunnel was developed completely in August 2017 and more tunnels around the city are being built in association with a huge budget.
This flood protection scheme has become doubtful. Arguments are on the costly investment and more questions are coming up. Is it effective flood protection management? How many tunnels are needed actually? Precisely the issue of climate change is not taken into account that flooding is not natural phenomenon but caused by man. On the one hand, it cannot be denied that most flood prevention projects have not been implemented for years, moreover, the built environment of Bangkok has changed greatly after the flood disaster in 2011. It is interesting to revise some data and information and discuss comprehensively on this flood protection scheme. The most serious question is; can this diversion tunnel scheme save Bangkok from the next big flood? The coming monsoon season may be the right time to prove it.

Topic:PRESENT WATER MANAGEMENT SYSTEM AND FUTURE CHALLENGERS FACED BY KANDY MUNICIPAL COUNCIL, SRILANKA

Kandy city is situated in central part of Sri-Lanka and recognized as the capital of central. It is a world Heritage city declared by the UNESCO by considering the historical values of the city. The permanent population of the city is about 120,000 and the ironically there are about 500,000 to 600,000 floating population exists in the city and the city is surrounded by range of mountains and a major river.
To provide safe drinking water and handling of wastewater are some of the major tasks of the Kandy Municipal Council and approximately 50,000 cu.m of water per day is required to cater this task. The main source for the system is the river flows through the outer skirt of city called Mahaweli which is the longest river in Sri Lanka and it is supplemented by an impounded reservoir constructed and the part of the city.
Unplanned urbanization and illegal solid waste dumping lead to contamination of water bodies and hence the quality of raw water getting deteriorates drastically and therefore, the more attention is needed for purification. This has been one of the major challenges faced by municipal engineers assigned for water sector in maintaining all water sources, ensuring much efficient water purification and effective water delivery system to the city community. Being the Kandy City is located in a hilly area surrounded by range of mountains, the undulation pattern of the city terrain restricted the uninterrupted water supply to city community and hence, the present water supply level decreases to about 75% from 90% in the last decade.
Following are the major challenges faced by the authorities on the Kandy water supply system which will be presented and discussed in detail in the proposed ‘Water Forum’:
1. Collection of turbid materials to water bodies due to unplanned urbanization and also the mild flood conditions generates due to sudden surface drainage run-off.
2. Chemical contamination of raw water sources due to illegal dumping of solid waste to water bodies that has resulted additional effort in water treatment.
3. Necessity of pumping water for high elevated areas during water supply that has eventually increasing the cost of water.
4. High level of NRW (approx. 40%)
5. Restrictions to rehabilitate due to lack of lands and resources.

Topic:Evaluation of urban drainage retrofitting responses on flood reduction in Ho Chi Minh City

The negative impact of urban flooding on socio-economic development is considerable, especially in the developing countries. Upgrading urban services, such as drainage systems, to keep up with the increasing demand and adapting urban infrastructure to maintain their functionality in a changing climate and socio-economic conditions is a management, planning and implementation challenge. Retrofitting like adaptation, either planned or autonomous, is a socio-technical process, where the motivation and ability of the stakeholders are important factors that are to be considered for implementing retrofitting actions. This paper explores the possibility of implementing retrofitting responses based on Motivation and Abilities (MOTA) framework. Motivation and abilities of the stakeholders, under two adaptation objectives i.e. Climate Change and Urbanization, in retrofitting urban drainage system in Ho Chi Minh City were explored. The MOTA scores for retrofitting to maintain current service levels, adapting to climate change and urbanization, were obtained on the basis of stakeholder consultations and surveys. The analysis of MOTA scores revealed that the motivation and ability of the stakeholders differed based on the adaptation objectives. Hence, it is important to consider the changing nature of motivation and ability of stakeholders while planning and implementing drainage retrofitting responses

題目:越南胡志明市都市洪水之風險管理政策與工具

本文回顧胡志明市的都市洪災近十年概況。成因如下:(i)與都市發展無直接關聯者,包括:河水水位上升、降雨量增加、以及上游水力發電大壩洩洪的水量;和(ii)與都市發展有直接相關者,包括:保水力下降、都市排水力下降、徑流水滲透率下降以及地層下陷。顯而易見地,都市發展的各種錯誤措施,是發生洪災最重要的成因;此外,氣候變遷讓海平面上升並增加降雨量,亦是讓災情更為嚴重的一項因素。
根據國際經驗和專家意見,建議胡志明市成立三個洪水風險管理政策小組:(i)對洪水做出讓步的政策:限制甚至禁止洪水泛濫敏感區的都市發展計畫,並復原曾被人佔用或為了都市發展計畫進行整地的重要溝渠和濕地;(ii)適應都市洪災的政策:增加保水力、避免都市洪水氾濫、確保都市各功能區有合理的地面高度;(iii)因應洪水風險的政策:加強都市開發區的滲水性,提高下水道系統和都市溝渠的排水能力,透過堤防系統、潮汐控制閥門和河/海水壩來防止渠道、河川及海洋的洪水。

Topic:POLICIES AND TOOLS FOR RISK MANAGEMENT
OF URBAN INUNDATION IN HO CHI MINH CITY, VIET NAM
This article gives an overview of the current situation of urban inundation in Ho Chi Minh City over last decade. This situation is caused by: (i) which not directly related to urban development, include: the rise of river water level, the increse of precipitation, and the water discharged from upstream hydropower dams; and (ii) which directly related to urban development, include: the reduction of water retention capacity, the reduction of urban drainage capacity, the reduction of run-off water permeability, and land subsidence. It is clear that mistakes in urban development are the most important causes of the inundation of the city; in addition, climate change, which increase sea level and precipitation, is a factor contributing to make the situation more severe.
Based on international experience and expert opinions, three policy groups for flood risk management in Ho Chi Minh city is proposed: (i) policies for concession to flood water: to limit or even to ban urban development projects in inundation-sensitive areas, and to consider the rehabilitation of important canals and wetlands which have been encroached or leveled for urban development projects; (ii) policies for adaptation to urban inundation: to increse water retention capacity to avoid spreading of urban inundation, and to ensure the reasonable ground level of each functional zone in urban areas; (iii) policies for response to flood risk: to strengthen the permeability of urban built areas, to improved drainage capacity of sewer system and urban canals and rivers, and to prevent flood water from the canals, rivers and sea by dike system, tide control gates and rivers / sea dams.

題目:以自然途徑為基礎朝向水資源智慧管理城市

城市快速成長與氣候快速變遷將會對於2050年六十億人的可居住性產生巨大的影響,且對於水資源、糧食與能源的可用性產生龐大壓力。經常發生洪患可能主要對城市地區造成較大傷害。除了水患風險外,缺水也是城市即將面對的議題。近期一份全球性研究顯示,每四座城市中就有一座城市面臨水資源的壓力。氣候變遷與城市化將會加劇城市河流水域邊緣水資源短缺的風險。這些挑戰督促我們發展出一套系統性的方法和都市規劃與水資源管理的典範轉移。

水資源在城市的宜居性上扮演重要的角色。為了要創造城市綠地、適應力及循環力,我們必須重新思考治理城市水資源的方式及恢服大自然的適應力。為了能夠恢復大自然排水能力並建立城市水資源循環,(重新)設計城市需要一個過渡期,從水源流失的城市邁向智慧管理水資源的城市。水資源智慧城市的概念,透過整合城市規劃與地方、城市、集水區規模的水資源管理,呈現出以自然為基礎的系統性途徑。創新以及和在地利害關係人、企業和研究機構的密切合作是持續學習與改進的關鍵,透過搜集與分析資料、建立以實證為基礎的自然適應,方能降低城市面對洪水、乾旱和熱浪的脆弱。

Topic:Nature based approaches Towards Water Smart Cities
Rapid urban growth as well as climate change will have tremendous impact on the liveability of 6 billion citizens (by 2050) and put huge pressure on water, food and energy availability. Frequent flood events will cause major damage in urban areas. Besides flood risk, water shortage is an increasing concern for cities. A recent global study shows that 1 in 4 cities already is water stressed. Climate change and urbanisation will further increase the risk for water shortage in peri-urban river basins. These challenges ask for a systemic approach and a paradigm shift in urban planning and urban water management.
Water plays an important role for the liveability of cities. To create green, resilient and circular cities we have to rethink the way we deal with water in our cities and restore the natural resiliency. A transition is needed to (re)design cities from drained cities towards water smart cities in order to restore the natural drainage capacity and close the urban water cycle. The Water Smart City concept presents a nature based systems approach by integrating urban planning and water management on district, city and catchment scale. Innovation and close collaboration between local stakeholders, businesses and research institutes is key to continuously learn and improve by collecting and analysing data and create evidence base for nature based adaptation in order to become less vulnerable for floods, droughts and heat waves.

Topic:Intelligent Flood Prevention Network and Disaster Management

Due to the characteristics of the geographical location of Taiwan, it is prone to the invasions of typhoons and heavy rainfall in summer. Besides, with regional environmental features and high-density development, once there is drastic rainfall, there is often a flooding disaster, causing people’s lives and property losses. In recent years, affected by global climate change, the weather patterns of flash flood and heavy rainfall have become more and more obvious. The frequency and scale of disasters have continuously increased, and the public’s demand on government units’disaster prevention energy relatively increases too, making the management agencies’flood prevention and response work intensified. For the past few years, with the development of IoT and microelectronic inductive component technology as well as through the steady and low energy consuming inductive components and data transmission systems, the possibility of developing a wide-area, low power consuming intelligent flood prevention monitoring network has greatly enhanced. The hydrological monitoring instruments that are developed in response to disaster prevention needs have gradually led to the development of low-power and low-traffic communication networks (LoRa, NBIoT, etc.) The intelligent flood prevention monitoring network has become an important development project at this stage.
With the construction of front-end monitoring equipment and communication network, how to use the data remote transmission system framework connected with the information obtained by the sensing layer to build a flood prevention disaster management decision-making system to help with disaster prevention decision-making and operation is the main job of this intelligent flood prevention management platform. As a result, the intelligent flood prevention management platform should include: monitoring information, hydro-information database, and water and disaster model database, with water monitoring Internet providing real-time monitoring data; database recording monitoring data, historical data, and integrating information from relevant units to build a huge amount of analysis platform and theme data pool; and model database providing real-time rendering results to provide reference for disaster prevention such as decision making, public display, voluntary disaster prevention, and facility operation. Intelligent flood prevention network and disaster prevention management include network platform framework, model and equipment development, on-site testing application, and model development and application. The development of related work will provide domestic water resources management techniques and water technology industry techniques, and further provide opportunities to cooperate with other countries to enhance the competitiveness of domestic disaster prevention industry.

題目:物聯網世代地下水管理的新思維與實作-以高雄市為例

水資源為人類生存與產業發展之必需品。由於極端氣候影響,造成地表水穩定度不足,地下水重要性大幅提升,因此永續管理地下水資源為重要課題。本研究提出地下水物聯網之概念,首先分別以電子水表及水位計,觀測抽水井抽水用量與所造成之水位反應,並以遠距傳輸設備即時回傳;其次以資訊平台進行資料倉儲、管理與展示,並發展管理介面,以利管理水權人是否超量用水;最後,應用大數據分析,從巨量資料中取出關鍵訊息,以利管理決策。
本計畫針對50口大水權抽水井,進行流量觀測,並以觀測鄰近17口觀測井水位。50口抽水井水權量為18.28萬CMD,佔大樹大寮兩區總水權量之44%,抽樣量具代表性,其抽水量為7.36萬CMD,量值穩定無太大變異,以水權佔比推估,大樹大寮兩區平均抽水量應為16.58萬CMD。搭配近期水位趨勢來看,自2015年來該區地下水位持平甚至微幅上揚,顯示該區地下水進出仍屬有餘,可用水量應大於16.58萬CMD,建議後續採滾動式增加地下水開發量,利用地下水水位反應逐步找出可用水量。

Topic:The Novel Idea and Implementation of Groundwater Management in the Era of IoT – A Case Study of Kaohsiung City

Water resources are essential for human survival and industrial development. Due to the extreme climate impact, the instability of surface water supply increases the importance of groundwater resource. Therefore, sustainable management of groundwater resources becomes an important issue. This study proposes the concept of the Internet of Groundwater (IoG). Firstly, an observation system include flow meters, water level gauges and devices f remote transmission is constructed to record the usage of groundwater resource and the associated response. Secondly, an information platform is developed for data storage, management and display. A management module for groundwater usage which can alert actively when the quantity of groundwater usage exceed the issued quantity is also developed. Finally, integrating analysis of data mining with the observed records is proposed to applied to extract key information to assist in the decision making of groundwater management.
50 production wells with huge water right and 17 observation wells are designed to construct the infrastructure of IoG. The total amount of water rights for the 50 wells is 182,800 CMD, about 44 % in the districts of Dashu and Daliao which means the result of the IoG is significant. Since observed from last August, the average quantity of pumpage is 73,600 CMD. The quantity remains stable. Based on the proportion of water rights in the two districts, the total volume of Dashu and Daliao might be 165,800 CMD. The trend of groundwater level since 2015 is slightly increased means that the quantity of groundwater usage (165,800 CMD) is still smaller than the safe yield. A rolling-wave planning is suggested to figure out the safe yield. The total amount of water in two districts can be increased 10% iteratively until the finding the value of safe yield.

Topic:Wastewater reuse and cases study in Taiwan

Extreme climate change will have a serious impact on Taiwan’s water resources. Reclaimed water is not affected by weather. Its water volume is large and stable, and its water quality is good. It is one of the important water sources in emerging water resources. In view of this, the Construction and Planning Agency of Ministry of the Interior and the Water Resources Agency of Ministry of Economic Affairs actively promote the policy of recycling and reuse of the urban sewage treatment plant discharge water. In addition to the legislation of Reclaimed Water Resources Development Act, they also promoted “Public Sewage Treatment Plant Discharge Water Recycling and Reuse Promotion Project” to set a new milestone for turning sewage water into available resources.
  This presentation will explain the main technical applications of reclaimed water development, domestic and international development experience and challenges, and by introducing relevant domestic cases, including the first in the country, Fengshanxi sewage treatment plant discharge water recycling and reuse of the reclaimed water, as well as the practical experiences from feasibility assessment, advanced planning, investment promotion, construction and commissioning, and performance management to the introduction of the current implementation of the reclaimed water plants in Linhai (Kaohsiung City), Anping and Yongkang (Tainan City) and Futian (Taichung City) to proceed to the discussion of relevant issues and provide a reference for subsequent development and promotion of reclaimed water.

題目: 斯里蘭卡康提市--水管理系統現況與未來挑戰
Topic:Present Water Management System and Future Challenges in the Kandy Municipal Water Sector

康提市位於斯里蘭卡的中心,為斯里蘭卡中部的中心,並因其城市的歷史價值受聯合國教科文組織列為世界文化遺產之都。永久居民人口約為12萬人,另有約50至60萬人為浮動人口,穿梭於肯迪市。肯迪市四周受高山圍繞,並有一主要河流流經。
康提市的首要任務中包含提供安全的飲用水及廢水管理,為此每天需要5萬立方公尺的水來處理這項任務。主要的水資源來自流經城市外圍的Mahaweli河流,這條河流同時也是斯里蘭卡最長的河流,次要來源為現有水庫,及部分來自城市的補充支援。
未經規劃的城市化和非法丟棄的固體廢棄物導致水資源受到污染,使得大自然環境的中的水源劇烈惡化,因此對於水資源的淨化需要更多關注。此項議題一直是市政府水資源部門工程師所面臨的主要挑戰,他們負責管理各種水資源,確保高效率的水資源淨化,和有效的水資源運輸系統。康提市的地理環境位於高山環繞之處,蜿蜒起伏的城市地形限制了水資源供給不受干擾的效率,使得目前水資源供給在過去十年自90%下滑至75%。
在水資源論壇中,將與各位報告目前康提市當局面臨的水資源供給系統的主要挑戰,如下所述:
1. 因未經規畫的都市化導致水源的污染以及排水系統的突然傾瀉導致水患。
2. 水資源因為非法的固體廢棄物傾倒受到化學污染,導致在水資源治理方面增加額外的負擔
3. 高海拔地區需要抽水以供給水源,最終導致成本提高
4. 無收益水量高(約40%)
5. 因缺乏土地和資源而限制了恢復的能力
