| 572 | 54114 | City of Asheville | Asheville | USA | North America | Public | 2017 | Regulatory | Short-term | Extremely serious | Through the heart of Asheville runs the French Broad and Swannanoa Rivers. These are susceptible to flooding during heavy rain events. EXPOSURE Seventy percent of the local drinking water supply is provided by the North Fork Reservoir. The dam and associated infrastructure provides the reservoir’s holding capacity. Past flood events and related erosion have shown the dam to be exposed to extreme precipitation and flooding events. VULNERABILITY The construction of the dam over 60 years ago was sufficient at the time, but an increased demand for water and a greater exposure to possible dam breach has now made vulnerability high. RISK The consequence of a dam breach is very high. The resulting flood would approximate a 500-year flood, with high velocity and the potential to cause massive damage downstream. This possibility, coupled with the impact of loss of drinking water for a substantial period of time, makes this a high risk. | 87882 | 2014 | (35.5951°, -82.5515°) | (37.09024°, -95.712891°) | |
| 573 | 35857 | City of Cincinnati | Cincinnati | USA | North America | Public | 2017 | Regulatory | Medium-term | Serious | Piping and pumping infrastructure in Cincinnati is aging. On a medium-term scale, we can expect that much of that infrastructure will need to be upgraded or replaced to deal not only with day-to-day water usage, but also with flood control, which will become more important, as we anticipate larger and more frequent flooding events in the future. | 298550 | 2015 | (39.1031°, -84.512°) | (37.09024°, -95.712891°) | |

The impact can be in the short, medium and long term. | 7980001 | 2016 | (4.711°, -74.0721°) | (4.570868°, -74.297333°) |
| 579 | 31176 | Prefeitura do Rio de Janeiro | Rio de Janeiro | Brazil | Latin America | Public | C40 | 2017 | Regulatory | Current | Serious | Increased economic activity in the state of Rio has taken to increased pollution in river beds, causing the quality of Guandu reservoir to decline, demanding a longer and more expensive cleaning process. The saline intrusion can also be a risk for the quality of water used for human consumption, mainly in areas still using underground water near the coast. | 6498837 | 2016 | (-22.9054389°, -43.5614471°) | (-14.235004°, -51.92528°) |

| 595 | 31166 | Jakarta City Government | Jakarta | Indonesia | South Asia and Oceania | Public | C40 | 2017 | Other | Current | Serious | Piped water coverage is still very limited, this has resulted in the utilization of underground water in an uncontrolled | 10155902 | 2017 | (-6.1751°, 106.865°) | (-0.7893°, -113.9213°) |
| 596 | 36254 | Comune di Venezia | Venezia | Italy | Europe | Public | C40 | 2017 | Declining water quality | Current | Serious | The large amount of water extracted from the wells increases the speed of the underground flow and reduces the rate of renewal of the water: this way the water quality worsens. the entity that holds the main responsibility for water protection is the Veneto Region which enacted the Water Protection Plan. | 261905 | 2016 | (45.4332515°, 12.3210704°) | (41.87194°, 12.56738°) |
| 597 | 36254 | Comune di Venezia | Venezia | Italy | Europe | Public | C40 | 2017 | Other | Medium-term | Serious | The "hydrological balance" has evaluated relevant quantities of water (442 Mm3 / y input, 169 Mm3 / y flow out) that indicate an high volume for a system that serves a population of over 600,000 inhabitants. The balance between the use of groundwater and the groundwater recharge is negative though also due to a great demand for water for industrial and agricultural systems. The use of water from wells (of excellent quality) by private individuals is still characterized by high levels of wastage in contrast with current legislation and with the basic concepts of rational use of the resource. | 261905 | 2016 | (45.4332515°, 12.3210704°) | (41.87194°, 12.56738°) |

| 600 | 36254 | Comune di Venezia | Venezia | Italy | Europe | Public | C40 | 2017 | Increased water stress or scarcity | Short-term | Serious | The decrease in total rainfall reduces the overall flow of the rivers; the increase of the concentration in a few, intense and short duration rainy events facilitates the surface water sliding: both of these phenomena reduce the possibility of groundwater recharge. To give more information, the current year (winter 2016-17) Veneto is experiencing a drought that occurs (for now) quite rarely. Factors contributing to drought were as follows: warm winter with little snowfall in the Alps and in the the Alpine foothills and minimal rainfall in the Po Valley. For this reason the Veneto Region is monitoring and controlling the situation, while temporarily reducing by 20% water for the crops. Similar situations have occurred in 2003 and 1994, however this is the year with less precipitation from 1930 to today. | 261905 | 2016 | (45.4332515°, 12.3210704°) | (41.87194°, 12.56738°) |

Description
CDP’s new infographic report ‘Who’s tackling urban water challenges’, produced in partnership with AECOM, the global infrastructure firm, and funded by Bloomberg Philanthropies, shows the first and most comprehensive dataset of global water action by cities and companies produced to date. Using information gathered from 569 cities and 1,432 companies, each reporting their water management activity, it illustrates how global cities and companies are responding to the escalating challenge of climate change and urban population growth.
The cities most concerned about their water supply lie in Asia and Oceania (84%); with serious risks also identified in Africa (80%) and Latin America (75%). 63% of North American cities deem climate change a risk to water supply, with fewer cities concerned in Europe (34%). 196 cities reported risks of water stress and scarcity; 132 a risk of declining water quality and 103 a risk of flooding.
Explore how cities and companies are acting on water, the CDP infographic report ‘Who’s in charge of Water Governance’, with case studies and full data is available at www.cdp.net/cities.
