The Challenge of Drain Grate Maintenance
In urban and industrial water management, drain grates play a crucial role in preventing debris from clogging sewage systems, retention basins and hydropower plants. These grates filter out foliage, branches and other obstructions, ensuring the smooth flow of water. However, over time, debris accumulation can lead to blockages, increasing the risk of flooding and requiring frequent manual inspections.
