collection, treatment and discharge of urban waste water,

treatment and discharge of waste water from food-processing industrial sectors

aimsaims to protect the environment from the adverse effectsthe adverse effects

of insufficiently treated urban waste water discharges and

of discharges of industrial waste water from food-processing industries

1.1. Objectives (1)Objectives (1)

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

1.1. Objectives (2)Objectives (2)

Collection and treatmentCollection and treatment of waste water in all agglomerations >2,000 inhabitants or population equivalents (including industrial waste water)

Secondary treatmentSecondary treatment (i.e. biological treatment) as rulerule; more stringent treatmentmore stringent treatment in sensitive areas and their catchments for aggl.>10,000 p.e.

Permit procedurePermit procedure

for treatment plants for discharges from the agro-food industry (>4,000p.e.)for industrial discharges into urban waste water sewerage systems

MoMonitoringnitoring of performance on

treatment plants and

affected waters (art.15 + annex I); controls on sewage sludge disposal/reuse
