Whether in major cities or rural regions, sewer networks ensure that wastewater is reliably disposed of. In most cases, that means wastewater is directed via pumping stations to the waste water treatment plants. It is typical for the various plant units, stations and treatment plants to be separated by long distances and they are often unmanned as a consequence. It is therefore important to ensure that the components used are as sturdy and reliable as possible, and work together perfectly – from the process control technology to the drive and automation technology, process instrumentation and power supply.
Information about pump performance, current flow measurement and fill levels is important for staying up to date with the status of the components being used. Efficient operation and observation of system processes are key factors in being able to enjoy secure system operation and provide a swift and targeted response in the event of a breakdown. Telecontrol technology is used to comprehensively connect the local stations to the plant-wide automation, regardless of how far they are from each other.
Today, wastewater streams in sewer networks are basically controlled on-site on the basis of locally available information. Although this method is associated with minimal investment costs and rapid implementation, its effectiveness is limited when it comes to reducing or preventing water pollution due to combined sewage water discharge. The way to prevent such discharge is through a targeted, centralized sewer network control system that eases the burden on the sewer network and compensates sewer system influx by utilizing the storage volume of components contained in the network. The goal of interventions into running discharge and storage procedures in drainage systems is to optimize operation of the sewer network and treatment plant. This is done by controlling valves, pumps and locks on the basis of current measurements of precipitation, water level and discharge.
The performance and efficiency of water transport and distribution systems is heavily dependent on the reliable and rapid detection and localization of leakages. A rapid localization of the leakage is critical for the prevention of potential secondary damage such as damage caused by the undercutting of foundations. Leaks do not only lead to the loss of drinking water that has been purified at high cost, but may also result in substantial economic losses. With SIWA Leak, Siemens offers a system to detect major leakages as well as small, gradual water losses in wastewater networks.
The parallelization and automation of work processes, their simplification and standardization, as well as digitalization and electrification are all important factors for improving the efficiency of your plant. Competing in the international market requires constant innovative strength and efficiency as well as increased productivity and quality – throughout the entire plant lifecycle. With our customized solutions, products, and services we help you achieve integrated plant management.
