Colombia - Proyecto de Reforma del Sector Agua Potable y Saneamiento Basico : evaluacion ambiental (Espanhol)

This environmental assessment (EA) outlines the absence of environmental policies, institutional framework, and instruments for an integral environmental management in the water sector, highlighted in Chapters 1-6, and, recommends a series of actions towards institutional strengthening. It then looks at the potential environmental adversity resulting from the implementation of the Water Sector Reform Assistance Project, and proposes mitigating measures as follows. Soil erosion, and land, and water degradation will occur as a result of excavations, affecting particularly slope terrains: land leveling, and vegetation propagation will minimize those effects; agricultural land losses, will be compensated with terraced land plots, of high agricultural productivity; appropriate drainage, and watershed management will minimize water concentration in sanitary landfills; similarly, solid waste disposal will be treated to prevent soil, and groundwater contamination; additionally, ditches will be constructed to reduce water losses, and contamination, and will contribute as well to the preservation of aquifers; vegetative propagation practices will be undertaken in, and around construction areas to reduce soil erosion, and air pollution; dry areas will require the use of small reservoirs to contain water, to be discharged through adequate drainage systems; conversely, in flooded areas, excess waters will be drained into reservoirs, a practice to be used in diverting river flows as well; traffic safety measures, and road signaling will be in place to control access roads.
