Dear colleagues
What are the impacts of climate change on the financial situation of water supply and sanitation services?

Dear Sofiane Boukhari ,
one of the cases would be ,
Increasing temperature levels will enhance the evaporation rates. This will evaporate the waters in reservoirs and water bodies which will stress and threaten the availability of water. Then water supply agencies and authorities require to different sources for satisfying water demands (may be move to groundwater extraction).
due to climate change rainfall level has decreased and the saturation of soil also decreased this leads water contamination got high concentration and water scarcity. so water treatment need for supply water. this condition will continue the technology is available but no water in future. so we have to reduce our climate change in anyway.
Climate change effect on the intensity and magnitude of rainfall distribution on the earth crust, increase of temperature it influence on the rainfall quantity will enhance the rate of evaporation.
Climate change is a very serious challenge in many countries, this results in reducing the quality of life. For instance where there is server cutting down of trees and increasing carbon dioxide content in the atmosphere global warming becomes a very serious treat. Atmosphere with high loading's of the concentration of pollutants have severe health implications.

In prolonged droughts, the quantity and quality of the water decreases, which overloads the capture and treatment systems and may increase the risks to the population; conditions in riparian forests, which protect water bodies from erosion, are altered; and groundwater recharge is reduced, a fundamental part of the hydrological cycle and a direct source of the resource for those who use artesian wells. Already in the floods, the chances of mixing between the waters of the rainwater system and the sewage system increase, which can increase the incidence of waterborne diseases; and overloads treatment plants and distribution infrastructure, with an increase in the number of interruptions and failures in the provision of these services.
"Climate change becomes obsolete in its sanitation infrastructure projects." The planning in the industry has used historical data to determine how much and how resources for sanitation should be invested. With climate change, this historical data loses value, since what happened in recent years does not serve as a parameter for what is to come. "The maximum and minimum flows [of water] will be overcome - or will not be reached - as a consequence of extreme weather events," the document said. In other words, droughts and floods will be the proof of sanitation systems.
In developing countries government expenses for water / sanitation traditionally have bee the most capital intensive investments for infrastructure. With CC costs further increase. It is essential to move from 'big pipe' solutions to more decentralized ones, where investment costs are less.
Another big problem of climate change over water resources is the change in the historical series of flow and precipitation data that may occur over the next few years. What directly affects the activities in the river basins and of environmental management and planning.
climate change gradually convert the environmental conditions for each region on earth and some of them will suffer a sever condition such as desertification, lake of water, decrease in quality and quantity of water, ..etc., so yes it will affect the financial situation of water supply
Hi,
about climate change effects on watershed management or any environmental aspects, it is necessary to keep in mind that hydroclimate systems are complex. They also contain a variety of water governance, policies, management approaches, and so on. Not all of the droughts or floods are because of climate change, however, climate change can plays a role and exacerbates the situation. But, revealing new spatial and temporal patterns in precipitation and temperature are interacted strictly with global warming and climate change which affects the environmental conditions directly in negative way. In total, my point here is we should not underestimate the effects of policy makers and managers decisions in watersheds. This factor along with climate change are important.
