The Urban Waste Water Treatment Directive (UWWT) (Council Directive 91/271/EEC) was adopted on 21 May 1991. The Directive concerns the collection, treatment and discharge of urban waste water and the treatment and discharge of certain industrial waste waters. Its aim is to protect the environment from the adverse effects of insufficiently treated urban waste water discharges and discharges of industrial waste water from food-processing industries.
Objectives and requirements
- Collection and treatment of waste water (including industrial waste waters) in all agglomerations with a population equivalent > 2000.
- Secondary treatment (i.e. biological treatment) as rule; more stringent treatment in sensitive areas and their catchments for agglomerations > 10000 p.e.
- Permit procedure for treatment plants, for discharges from the agro-food industry ( >4000 p.e.) and for industrial discharges from urban waste water sewerage systems.
- Monitoring of performance on treatment plants and affected waters and controls on sewage sludge disposal / reuse.
