UWWTD appliesUWWTD appliesto all agglomerations having the organic load of more than 2,000population equivalent
to agglomerations with less than 2,000 p.e. having collecting systems in place
to food-processing industries having more than 4,000 p.e. and discharging treated wastewater directly to receiving waters
Types of waste water concerned by the directive:Urban = domestic, or
mixture of domestic & industrial, and/or run-off rain water
Domestic = from residential settlements and services
Industrial = from premises for carrying on any trade or industry, other than domestic and run-off rain water
