 In terms of manpower, the best practices of the region reflect less than 3 employees per 1000 connections.In less populated areas, it can be difficult to determine the number of employees per connection, as services are often bundled by the government with other civic services, but the World Bank estimates that the number of employees per connection exceeds this in medium-sized towns, with somewhere between 5 and 14 employees assigned per 1000 connections.Non-revenue water, which is the difference between produced and invoiced water is also difficult to guess, given low measuring levels in Ecuador.
