Pressure management is one of the basic elements that should be included in a well-structured physical water loss management strategy. The rate of loss / leakage in water distribution networks is directly related to the pressure provided by promotion or attraction. If your network is not measurable, it cannot be managed. First of all, it is necessary to create measurable regions on the network. Since the pipes in old type distribution systems are largely interconnected, management and measurement are not possible. In order for the network to be managed more efficiently, it must be divided into measurable and isolated regions called DMA (District Metered Area). Each zone is hydraulically separated from the other pressure zone, and we come across a controllable network model. If pressure is not controlled, water losses increase and malfunctions increase due to high pressure. Pressure should be provided in accordance with the characteristics of the region in order to reduce losses and reduce the number of failures in the hydraulically separated pressure management (DMA) regions. With the dynamic pressure management application, night flow should be followed and management should continue in this direction.
Active leaks must be detected and leak points on the line must be repaired. Leakage points should be determined by navigating through the network over the numerical data available, especially by making acoustic listening during the hours when the noise is low. Repairing detected leak points is an important factor in reducing water losses. It is a process that should be applied periodically.
The values obtained from the flowmeters and pressure sensors on the by-pass region formed on the line are evaluated instantly by the SCADASU Electronic BKV Controller and the pressure on the line is kept at the desired value by sending a command in the direction of opening or closing. There are two units that provide control of the system. They are named as Electronic and Hydraulic Control Unit. The microprocessor inside the electronic unit controls the hydraulic unit by evaluating the data it receives from the flow meter and pressure sensors. The hydraulic unit controls the pressure control valve.
The Electronic Unit sends the inlet pressure, outlet pressure, instantaneous flow, total flow, the battery level inside the unit and the level of the external energy source to the system center in determined periods. The GSM communication module in the electronic unit remains in continuous on-line connection with the system center. In case of communication interruption, it keeps a record in itself, when communication is re-established, it sends all data back to the center.
When unexpected situation occurs, you can quickly send full open and close command to the pressure control valve.
