Tunnel dewatering in Panama

A large number of BBA portable pumps were used last year for a tunnel dewatering project in Central America. This concerned planned repairs to a 4,250-metre-long tunnel located in Panama. The tunnel is part of the HydroElectric project in the province of Boca de Toro where a power plant, with a capacity of more than 223 MW, generates energy via two turbines at the dam.

Before the repair work on the tunnel could start, it had to be pumped dry. A large part of the tunnel was dewatered via two 10-inch HDPE pipes and gravity technology. In order to remove 46,000 m³ of residual water in the last few metres of the tunnel, the Spanish dewatering company Ferrer S.L. shipped kilometres of HDPE pipes and a number of 6" and 8" vacuum assisted diesel pumps to Panama, enabling the tunnel dewatering project to be successfully completed.
