We have a project in Medellin, Colombia. The project has large areas of vegetation. In the driest month (January), it rains in average 12 of the 31 days. The average rainfall in this month covers 70% of the water demand for irrigation according to the calculation methodology specified in the LEED Reference Guide. Hence only 30% of the water demand will be covered by potable water during this month. Is it possible to achieve the credit under these conditions?
