In the midst of construction on the new Puerto Mallarino plant, the city of Cali, Colombia, was faced with possible water rationing as a result of increased consumer demand. To quickly provide economical water services in the interim between construction and operation of the new plant and so avoid water rationing, the public utility added 83 ML/day (19 mgd) to the capacity of its 50‐year‐old Rio Cali plant. This plant provides the city's most economical supply and the upgrading, which used indigenous materials, was remarkably inexpensive.
