New measuring stations enable fair billing of wastewater volumes

Court wastewater treatment plant modernised

The wastewater from the communes of Champoz, Valbirse, Sorvilier and Court is piped to the Court wastewater treatment plant. Until now, the wastewater fees were charged to the four municipalities according to a defined key. With the new measuring points installed by STEBATEC, the wastewater can now be billed according to the actual quantities. 

The four new measuring points 

Measuring station Champoz 

The first measuring point is in Champoz. In the new shaft built for this purpose, a fully filled stationary flow meter using EMF was installed. The new control cabin contains the electrical panel, the measuring transducer, and a mobile router with SIM card for data communication with the control system of the Court sewage treatment plant. 

Measuring station Valbirse 

In the second newly constructed measuring point, near the Valbirse community, a partially filled stationary flow measurement of nominal size 600 was installed. Since there was no power connection nearby here, a 300-metre-long cable protection pipe had to be constructed for the supply cable and routed over two bridges on the Birs.  

Measuring station Sorvilier 

The third measuring point after Sorvilier was also equipped with a partially filled stationary flow measurement, this time of nominal width 300. In addition, a pneumatic control damper was installed. This makes it possible to regulate flow rates in such a way that, in the case of large amounts of water, the existing stormwater basin is filled first instead of overloading the STEP Court. In this way, discharges can be avoided, and a contribution is made to the protection of the water bodies. 

Measuring point wastewater treatment plant Court 

The fourth measuring station is the inflow measurement of the Court sewage treatment plant. A TF stationary flow measurement of nominal size 700 in the open channel. 

All measuring stations were equipped with STEBAnet mobile radio, a system for data transmission that is available integrated in the TF transmitter. They work with SIM cards, as there are no DSL connections at the respective stations. Thus, the stations are always connected to the STEP Court.  

The volume settlements are made directly in the process control system. The administrative effort can be kept small in this way.

Products in use

Ultrasonic transit time difference measurement with dry weather gutter
The TF Stationary Flow Measurement is a calibrated measuring channel for backflow-free flow measurement of wastewater, raw wastewater and rainwater in open channels or open channels.
Special solutions for measuring wastewater, raw wastewater and rainwater under the most difficult conditions.
When the impossible becomes possible. High flow velocities, steep gradients, tight spaces, large measuring range. The more difficult the measuring task, the more suitable is the stationary flow measurement, which can often be retrofitted in existing structures and shafts.
The reliable discharge control for wastewater and rainwater
Precise and easy to maintain throttle system for stormwater tanks and wastewater structures. The fast, almost self-cleaning and remotely controllable butterfly valve with pneumatic actuator is based on the flow measurement integrated in the system and limits the flow to an arbitrarily adjustable quantity. As long as the maximum flow is not reached, the flap remains open, while the flow measurement system measures precisely even when partially filled.
Secure and volume-reduced data transmission on the Internet and in networks.
Networking and remote control of automation systems STEBAnet mobile, fixed and leased lines are data communication systems for decentralized control systems. Measurement data and control information are recorded on site for backup purposes and cyclically sent in packets or compressed form to the database of the central process control system. STEBAnet communicates in a way that preserves data volume and establishes connections only when needed, for example when a user at the process control system is viewing live data.
