Collection system is interrupted after soil collapse Once again, the population of Rio Branco suffers from a lack of water this Monday (27) due to supply problems. This time, an earth movement damaged the electrical network of the Water Treatment Station II (ETA II), on Rodovia Transacreana, in the Floresta Sul neighborhood. The problem occurred less than a week after Riobranquenses ran out of water at home. Last Thursday (23) an electrical failure compromised the operation of ETA II due to successive fluctuations in the electricity supply between Wednesday night (22) and Thursday morning. ? Join the g1 AC channel on WhatsApp Supply began to be normalized on Friday. However, this Sunday, the movement of the ground damaged the underground cables that supply the collection pump, causing overheating and a short circuit that interrupted the equipment's operation. The treatment plant was shut down due to the problem. High voltage cables broke after ground movement at ETA II Archive/Saerb The Operational Control Center (CCO) verified that there was an interruption in the power supply to the KSB pump. The equipment is responsible for sending up to a thousand liters of water per second to ETA II. As a result, the supply system was interrupted in the entire area served by ETA II, which corresponds to 60% of the city. The affected areas are: Central Regional Plates Horto Florestal Calafate Second District São Francisco. In an interview with Rede Amazônica Acre, the president of Saerb, Enoque Pereira, said that there was an initial short circuit last Thursday (23), but the situation was resolved and supply remained normal. "The team quickly managed to overcome the situation, but the ground moved and our underground network of eight cables broke. We stopped the service to continue today [Monday, 27] because they are high voltage cables and the risk of accidents to our workers is high. We hope that by ten o'clock at night, at the latest, we will be able to return all supplies", he highlighted. To find and access the damaged part, it was necessary to excavate the area. The work was done with machines and also manually. In addition to the emergency repair, Saerb initiated a permanent solution to prevent similar situations from occurring again. Water Treatment Plant (ETA II) Archive/Saerb "It's an old situation, we've already lost more than a third of our decantation pond, which helps remove material before reaching the treatment area. The substation is also compromised, access to the tower compromised, we're even going to demolish it. The year before last was a more dramatic situation because we had to stop the ETA for more than three days because everything broke down and we got around that situation and returned to normal", he lamented. Also according to Saerb, the pump's electrical supply system will no longer be underground and will become aerial, with the installation of poles and a compact network, similar to that used by electricity concessionaires. All necessary material is being provided so that the services can be carried out this Monday (27). "We dug up all the wiring and detected that some points had completely broken. We're going to do wiring on top, it's not recommended, but we're going to do it until we see the best way to solve it. We're looking to do a study to build a large lake and dam to avoid the river. Every year it rises and falls very quickly, it's not just here, it's throughout the Amazon, and our team has done everything to keep it from stopping", he argued. Recent history This is the third problem that compromises the water supply in Rio Branco this month. On July 6th, residents of different regions of the capital also faced a lack of water after a failure in one of the buoys on the float used to collect water from the Water Treatment Plant (WTP I). At the time, the equipment presented problems during the collection operation on the Acre River, reducing the production of treated water and affecting supply in several neighborhoods. Supply had to be gradually resumed after repairs were completed. According to the Rio Branco Water and Sewage Service (Saerb), the problem was caused by successive fluctuations in the electricity supply between Wednesday night (22) and Thursday morning, which damaged components of the electrical system at the ETA II substation. As a result, the unit's operation was interrupted, affecting supply in neighborhoods in the Second District, Calafate, Estação Experimental and surrounding areas, as well as the upper part of the city. (Read the full note below) This Friday, Saerb reported that the repairs were completed and that the water distribution was back in operation. The expectation is that supply will gradually return to normal throughout the day, as the network becomes pressurized again and the reservoirs are filled. "Saerb's technical teams are working to replace the damaged equipment and normalize the system, so that the operation of ETA II can be reestablished as soon as possible", added the note. Read Saerb's note in full We inform you that the water supply is compromised due to an electrical failure at the Water Treatment Station (ETA II), recorded in the early hours of this Thursday morning (23). The problem was caused by successive fluctuations in the electricity supply between last night and early today, which damaged components of the substation's electrical system, affecting the unit's operation. Saerb's technical teams are working to replace damaged equipment and normalize the system, so that ETA II's operation can be reestablished as soon as possible. Supply will be gradually resumed after the completion of the services, with normalization
