The UWWT Directive lays down four main principle
obligations:
Planning
The planning aspects of the Directive require Member States
to:
- Designate sensitive
areas (sensitive water bodies) in accordance with three
specific criteria, and to review their designation every
four years;
- Identify the relevant hydraulic catchment areas of the
sensitive areas and ensure that all discharges from agglomerations with more than 10 000 p.e. located within the catchment shall have more stringent than secondary treatment;
- Establish less sensitive
areas if relevant;
- Establish a technical and financial programme for the
implementation of the Directive for the construction of
sewage collecting
systems and wastewater treatment plants addressing treatment
objectives within the deadlines set up by the Directive
(and the Accession Treaties for new Member States).
Regulation
The regulation aspects of the Directive require Member States
to:
- Establish systems of prior regulation or authorisation
for all discharges of urban wastewater;
- Establish systems of prior regulation or authorisation
for discharges of industrial wastewater into urban sewage
collecting systems to ensure:
- Treatment plant operation and sludge treatment will
not be impeded;
- No adverse effect on the environment (including receiving
waters) will occur; and
- The safe disposal of sewage sludge.
- Establish systems of prior regulation and/or specific
authorisation and permits for food processing industries;
- Ensure that all urban wastewater generated in agglomerations with more than 2000 p.e. are supplied with collecting systems, and that the capacity
of these is such that all urban waste water is collected,
taking account of normal local climatic conditions and seasonal
variations;
- Ensure that national authorities take measures to limit
pollution of receiving waters from storm water overflows
via collecting systems under unusual situations, such as
heavy rain;
- Ensure that wastewater treatment is provided for all agglomerations
at the level specified by the Directive and within the required
deadline:
- Secondary
treatment is the basic level that should be provided,
with more stringent treatment being required in sensitive
areas and their catchments;
- For certain discharges in coastal waters treatment
may be less stringent (i.e. primary
treatment) under certain conditions and subject
to the agreement of the European Commission;
- For agglomerations with a population
equivalent of less than 2000 but equipped with a
collecting system, appropriate
treatment must be provided.
- Ensure that technical requirements for the design, construction,
operation and maintenance of wastewater treatment plants
treating urban wastewater are maintained and that they ensure
adequate capacity of the plant and treatment of urban wastewater
generated in agglomerations taking into account normal climatic
conditions and seasonal variations;
- Ensure that the environment is protected from adverse
effects of the discharge of wastewater;
- Ensure that the environmentally and technically sound
reuse or disposal of sewage sludge is subject to general rules, registration or authorisation
and that the requirement of specific inter-linked Directives
for agricultural re-use (86/278/EEC), incineration (89/429/EEC
and 89/369/EEC), and landfill (99/31/EC) are respected.
The disposal of sewage sludge to surface waters is banned.
Monitoring
The monitoring aspects of the Directive require Member States
to ensure that monitoring programmes are in place and that
the programmes correspond to the requirements laid down in
Annex I D of the Directive (
pdf 160KB) in terms
of parameters monitored, analytical method and sampling frequency.
Member States are required to ensure that both discharges
from urban wastewater treatment plants and receiving waters
are monitored.
Information and reporting
The information and reporting provisions of the Directive
require Member States to ensure that the following are put
in place:
- Adequate mechanisms to allow the co-operation and exchange
of information with other Member States in cases where discharges
of wastewater have a transboundary effect on water quality
of shared waters;
- Adequate reporting procedures and databases to allow the
provision of information to the Commission on:
- Transposition of the Directive into national legislation,
implementation programmes and situation reports on the
disposal and re-use of treated urban wastewater and
sewage sludge;
- Status of collecting systems, efficiency of treatment
plants (i.e. treatment level and monitoring results)
and the quality of receiving waters; and
- Status of discharges from the food-processing industry
to surface waters;
- Access for the public to relevant information and the
publication of status reports every two years on the status
of wastewater collection and treatment and disposal or re-use
of sludge.
