The purpose of this study was to develop performance indicators for 13 selected water, wastewater, and combined water and wastewater utilities in Ecuador from data supplied by the utilities themselves. The performance indicators cover operational, financial, and personnel activities. Of the 13 utilities surveyed, three provide water services, two provide wastewater services, and eight provide both. The principal objective was to prepare a profile of each utility to serve as the beginning of a time-series database to be updated annually or as often as thought useful. Salient features and trends would be identified and monitored and would be used to evaluate utility performance. The profiles are designed as stand-alone documents to be used independently of each other.
