Tunnel dewatering in Panama
11 February 2020
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.
