Water leakage
Water systems suffer water losses, and a significant cause is a leakage in the pipelines. There are numerous leaks and ruptures in the water pipeline system that affects the entire flow of the water. The city of São Paulo loses more than 20 percent of its treated water, ready for distribution due to the leaking in the pipes. Sabesp describes the water loss as physical or actual loss and non-physical or apparent loss. Physical loss is the volume of water that was lost through the pipe leakages and could not be consumed by the population. These leaks occur due to the high pressure in the pipes and the aging of those pipes. Non-physical losses are the volume of water consumed by the population without being accounted for by the company. People consume water with different fraud measures. The water losses in the water system can be linked with the irregularity done by the company in maintaining the installed infrastructures and the operation and flow of the water system. While the average production of the company was 64 meters cubed per second, the water loss was 20.6 meter cubed per second. Out of 40 percent of what is produced, 10 percent corresponds to fraud, 10 percent to the non-physical losses, and the remaining 20 percent correspond to actual water leaks. With significantly high water losses through leakages in the water pipes, Sabesp has adopted various ways of managing and minimizing water loss. They have implemented rezoning in 5 sectors per year along with renewing and upgrading 12.5 percentage of the residential meters in the system per year. A significant initiative of reducing water leakage by Sabesp is by lowering the water pressure in the system. The old pipes cannot hold the high demand of the water flow during the peak hours and end up leaking. By reducing the water pressure, this minimizes the velocity of the water flow, thereby minimizing the leakage and water loss.Controversy During the 2014 Water Crisis
One of the leading factors into the 2014 Water Crisis was the mismanagement of water resources by SABESP in the Metropolitan Area of São Paulo. Primarily, through the lack of investing in infrastructure. As mentioned above, SABESP suffers with water leakage through their piping. This was especially felt during the 2014 Water Crisis in São Paulo. Not only do they lack infrastructure strengths in dealing with water leakage, the original design of SABESP pipelines and water tanks is flawed. The original design includes water tanks that are unequally concentrated in central São Paulo. The hardest hit area during the Water Crisis was southern São Paulo in which a large portion only has one water tank. A way that SABESP has tried to offset this is by using Boosters and Pressure Reducing Valves. However, they have been only a short term solution to a long term problem. This is one of the leading reasons as to why the 2014 Water Crisis occurred. The reason for this lack of adequate infrastructure is due to the private-profit status of SABESP. In 1994, SABESP started the privatization process. While, São Paulo is the biggest shareholder of SABESP, SABESP still strives for profit. It is a publicly guaranteed monopoly, but its profits are privatized. This reduces the incentive to invest in long term infrastructure changes for the short term profits. During the Water Crisis of 2014, SABESP failed to warn their citizens by not telling them that they were rationing water resources. The lack of transparency was especially prevalent during the 2014 Water Crisis concerning the major bonuses given to higher ups despite the thousands who suffered from thirst.References
