MORAZAN DAM EMERGENC

closed

The Morazan Dam Emergency Project will: (a) maintain the structural integrity of the Morazan Dam; (b) increase the reliability of the power plant's auxiliary system; and (c) strengthen the National Power Company's (ENEE's) emergency preparedness planning and its capacity to monitor dam performance. The project comprises: (a) an underground investigation program with deep rock borings with corresponding instrumentation, followed by high pressure injection of sealants into the rock mass; (b) impermeabilization of the power plant sump, construction of about 300m of additional drainage galleries to evacuate filtrations by gravity flow, and plugging of the diversion tunnel; (c) installation of additional electrical and mechanical equipment to substantially increase service reliability of the auxiliary electrical system of the power plant; (d) supply and installation of new and complementary instrumentation to monitor foundation pressures and water filtrations; (e) consulting services to: (i) supervise the impermeabilization works; (ii) carry out a structural and electro-mechanical review of the dam; and (iii) prepare an emergency preparedness and evaluation plan; and (f) training of ENEE staff in underground investigations, pressure sealing of foundations, monitoring of hydrostatic foundation pressures and water leakages in high dams and electrical system stability.
