Aquapole Grenoble


Application : Sanitation

The Aquapole wastewater treatment facility was built in early 1988 to solve the effluent treatment problem of the city of Grenoble, France.

Aquapole treats wastewater from 48 towns, with a capacity of 500,000 population-equivalent. Designed to accommodate average flow of between 250,000 m3/day and 450,000 m3/day, it is operated by SDA (Société Dauphinoise d'Assainissement), a 50% subsidiary of the OTV Degrémont Group.
Although the plant was originally fitted with building control facilities, it was decided to implement a real Remote Management system (with local archiving capability) to increase the operational reliability of the entire sewer system.
    

The system installed by Cegelec Grenoble (Eybens) includes 21 RTUs connected over the dial-up phone network or a dedicated line to the PC500 master station, via a CS100 front-end processor.
The PC500 remotely controls an operator console located in the plant manager's office.
The primary lift station and four secondary stations can share data over an "Inter-RTU" dedicated line. RTUs with analog inputs also collect tank levels through ultrasonic sensors.

Remote management capabilities such as real-time alarm monitoring, daily reports on the various works flowrates, and reduced field maintenance are key to the successful operation of the plant.
Users also responded favorably to the modular construction and easy setup of the remote management devices. Today, the 500,000 residents served by Aquapole are fully aware of the major benefits provided by the treatment of effluent before it is discharged to the river. They also estimate that the integration of the plant into the natural environment is a real success.
