Passavant® Cable-Operated Bar Screen COB-XXL & Passavant® Penstock

Hangares, Mexico


The large amount of water occurring, especially in the rainy season, led to regular flooding of the Hangares metro station. To prevent this problem, the construction of the deep pumping station was planned and implemented. The deep pumping station Hangares is operated by SACMEX (Mexico City Water Authority) and is designed for 50,000 inhabitants. It is a bypass of Lumbrera 8. The pumping station is equipped with its own power generators. Aqseptence Group supported the new construction by supplying the rakes and shut-off devices required for the pumping station.


The rakes Passavant® COB -XXL and Passavant® penstocks offered by Aqseptence Group GmbH provide the optimal solution for the existing requirements under the toughest operating conditions in the deep pumping station of Hangares. The rakes and penstocks manage rain and thunderstorms as well as dry periods to the fullest satisfaction of the customer.
