Summarize this article for a 10 year old
Integrated urban water management in Medellín, Colombia is considered to be an overall success and a good example of how a large metropolitan area with moderate income disparity can adequately operate and maintain quality water supply to its many citizens. This is quite remarkable given the large urbanized population in the metropolitan area of the Aburrá Valley of 3.3 million, many of whom live on the slopes of the Aburrá Valley where Medellín is situated and highly prone to landslides and stormwater erosion. Sound urban water management within the metropolitan area of the Aburrá Valley is carried out by a set of technically strong institutions with financial independence—and lack of political interference [2] such as Empresas Publicas de Medellin (EPM).[3]

The metropolitan area of the Aburrá Valley is located near the equator but with a high elevation, the average climate is quite mild without great variation in temperature and rainfall. Consistent and adequate precipitation in the surrounding basins usually ensures that nearby water basins feeding the Aburrá Medellín River basin and subsequently the MAM can store approximately 178 BCM[clarification needed] of water for the Metropolitan Area of the Aburrá Valley.[2] Adequate supply and good resource management has allowed nearly 100% of MAM citizens across ten municipalities to receive piped water.
Substantial challenges remain however for Colombia's second largest urban and economical center in dealing with an increasing urbanization rate and the settling of inhabitants higher up the hillsides within the narrow valley. Drainage of stormwater is probably the most significant concern for the Metropolitan Area of the Aburrá Valley government and managing institutions. A stormwater management plan has been instituted to help address the adverse effects of urbanization, lack of infrastructures in poorer neighborhoods able to handle stormwater, river conservation and risk assessment.[2]
