91/271/EEC - Urban waste-water treatment
Urban waste-water treatment
General Information
This document specifies general requirements, performance requirements and conformity test procedures for automatic sampling devices (samplers) for water and waste water that:
— sample water and waste water from non-pressurized (i.e. open to atmosphere) channels or vessels;
— sample over extended periods to collect discrete or composite samples based on time, event or flow proportional sampling.
It does not include sampling systems built into online and in-line analysers.
The general requirements include functional facilities that samplers need to meet users’ applications and information that needs to be included in associated documents.
The test procedures specify uniform methods to be used when determining key performance characteristics of samplers at one or more set sample volume. It is for the sampler manufacturer and/or user to decide on the required set sample volume(s). All of the test procedures are to be carried out under laboratory conditions. It is recognized that for some samplers, certain test procedures are not applicable.
Statistical procedures are specified for evaluation of the test data. Some example calculations are provided.
Specific sample integrity requirements are specified for samplers to be used for the collection of samples of final effluent or influent for the purpose of monitoring the performance of urban waste water treatment works. Samplers to be used for other industrial applications do not need to be assessed against these specific sample integrity requirements.
This document does not cover the installation and on-going use of samplers.

This European Standard specifies the objectives for drain and sewer systems outside buildings. It specifies the functional requirements for achieving these objectives and the principles for strategic and policy activities relating to planning, design, installation, operation, maintenance and rehabilitation.
It is applicable to drain and sewer systems from the point where wastewater leaves a building, roof drainage system, or paved area, to the point where it is discharged into a wastewater treatment plant or receiving water body.
Drains and sewers below buildings are included provided that they do not form part of the drainage system for the building.

This guidance standard specifies equipment and procedures for collecting floating pupal exuviae of Chironomidae from aquatic habitats; rivers from source to estuary, canals, ponds, lakes and sea coasts. Guidance in preparing specimens for subsequent identification is provided. These samples provide representative data on relative species abundance, suitable for numerical analysis, classification and monitoring of environmental conditions.

This CEN Technical Report gives one of a series on sludge management options and describes good practice for the disposal of sludges and sludge treatment residues to landfill where national regulations permit.
This document is applicable to sludges described in the scope of CEN/TC 308 i.e. specifically derived from :
- storm water handling ;
- night soil ;
- urban wastewater collecting systems ;
- urban wastewater treatment plants ;
- treating industrial wastewater similar to urban wastewater (as defined in Directive 91/271/EEC ) ;
- water supply treatment plants;
- water distribution systems;
but excluding hazardous sludges from industry.
