An association of twelve municipalities in Wallis was looking for a just cost allocation solution to account for the high foreign water content in the waste water entering the treatment plant. The measuring system installed now records the different outflows and thereby rewards those municipalities that already have installed a separation system.
For 15 years, VKA and STEBATEC, the German Association for Sewerage and Wastewater Treatment, have been working together successfully. The latest milestone is the introduction of ARAbella ONLINE: With the web-based process control system, processes can be controlled online via remote access. A management of the waste water quantities becomes possible.
The Reinhalteverband Mühltal & Region Böhmerwald in Upper Austria consists of 24 municipalities, looks after around 1.000 km of sewer, 18.000 sewer shafts, 300 pumping stations, 60 storm waterbasins and 6 sewage treatment plants. Despite its size, however, the drainage system reached its limits. The individually operated storm waterbasins, for example, relieved the load rigidly into the recipient in the event of overload.
Association of the Schwarze Pumpe Industry Park, D-Spremberg
As municipal company of the association of the Industry Park Schwarze Pumpe, the city of Spremberg and the municipality of Spreetal, the ASG Spremberg GmbH is the service provider to one of the largest industry parks in the south of Brandenburg state with many large and medium size companies that provide over 4,300 jobs.
Rügen water and waste water supply municipal association
he Rügen water and waste water supply municipal association (ZWAR) is responsible for the waste water management throughout the Baltic Sea island of Rügen, which turns into a tourist strong hold each summer. During that season, the waste water flow is many times the normal flowso that extreme fluctuations must be managed.
The BKW power plants of Berne, Switzerland, measure the wa-ter flowing to the Spiez hydropower plant at the Wimmis weir. The water flow is measured by an ultrasonic time domain meter from STEBATEC. Fairly high peak discharge flow rate of up to 15 cubic meters a second as well as the plulsating, turbulent flow conditions are particular challenges to the measuring equipment.
When ready, the Gotthard base tunnel will be the world’s longest railway tunnel. After a successful initial installation phase in 2006, additional installations for measuring the flows of water from the construction site and the entering well water are required in the section from Faido towards Sedrun in 2009.In the Faido – Sedrun section, the water flows in the drai-nage ducts after the Piora syncline and in the Borel zone are to be measured, the measuring data transferred to the tunnel portal by a suitable data transmission system and processed automatically by customized computer software so that the measuring results can be submitted to the supervisory authorities and the geologists as fully analyzed data sets.
The waste water treatment plant Radet near Leukin the canton of Wallis treats the waste water of12 municipalities. Recently, the administration union had installed additional measuring pointsin the sewerage system to improve the billing accuracy. However, the inflow to the treatment plant was still not measured. That would have required substantial input at the construction end and caused unreasonable cost.
Keramik Laufen AG is one of the world’s leading manufacturers of bathroom products. The factory produces waste water, which is disposed of in the local sewage treatment plant. In order to draw up a consumer-oriented cost statement, the waste water in the plant’s outlet, as well as the inflow into the plant, must be precisely measured.
Wastewater treatment plant Langnau im Emmental, wastewater storage basin Zeughaus
“The LDM is a very intuitive system. The transmitter provides the information I need at a glance” says Hans Stucki, plant manager of ARA Langnau, who wanted a precise and reliable measuring device to limit the amount of water transferred and to measure dry weather quantities for billing.
Extraneous water measurements of all municipalities in the catchment area of the ARA Wangen - Wiedlisbach
Already 5 years ago a measuring campaign was carried out to determine the extraneous water in the catchment area of the ARA Wangen – Wiedlisbach. In order to determine an up-to-date, polluter-oriented cost distributor, the current discharge values of the connected communities with 15 measuring points were to be determined.
