Chimbote Submarine Outfall System Complementary Studies

Project Features
Updating of preliminary studies to provide a basis for revised design of the ocean outfall in the seaport city of Chimbote with a population of 450,000 and 30 fish meal plants that discharge wastes with minimal pre-treatment to the Bay of Ferrol causing pollution of the bay and the adjacent coastal zone; investigation of liquid waste load generators including projections of quantities and maximum flow of domestic and industrial liquid wastes over the period 2005 to 2015; oceanographic investigations to measure ocean currents using Acoustic Dopler Current Profilers, biological investigations, and bathymetric, geophysical and geotechnical surveys; and investigation of environmental factors and navigational constraints so as to form the database for mathematical model simulations of various lengths of the outfall (a length of 4 km was selected with effluent discharge at a water depth of 30 m as the basis for final engineering).

Scope of Services
Projections of domestic and industrial liquid wastes as well as options for waste minimization and clean production; preliminary design of treatment facilities; interpretation of geophysical and geotechnical investigations; supervision of structural aspects of outfall design; conduct of environmental impact analysis; preparation of cost estimates and contract documents.
