Further sections of the document contain procedures for and information on quality assurance, occupational health and safety, and proper documentation (optical documentation and reports) in order to qualify the actual conditions. DWA-M 149-6 will be harmonized with the revised DWA-A 13

19、9 and DIN EN 1610, which is currently under revision. DWA-M 149-7 will deal with the environmental assessment of the conditions of drain and sewer systems. The aim of DWA-M 149-8 is to give clients and contracting authorities guidance on how to draw up clear, comprehensive specifications for optical

20、 inspections as in DWA-M 149-5. At the same time, the Supplementary Technical Conditions of Contract (ZTV) will help tenderers, contractors and inspectors alike by ensuring the descriptions of the technical standards required by the client are easy to understand and transparent.

DIN EN 13508-1:2013-01 EN 13508-1:2012 (E) 5 Introduction Drain and sewer systems are part of th

40、e overall wastewater system that provides a service to the community. This can be briefly described as: removal of wastewater from premises for public health and hygienic reasons; prevention of flooding in urbanised areas; protection of the environment. The overall wastewater system has four success

41、ive functions: collection; transport; treatment; discharge. Drain and sewer systems provide for the collection and transport of wastewater. Historically, drain and sewer systems were installed because there was a need to remove the polluted water to prevent diseases. Traditionally, drain and sewer s

42、ystems were constructed to collect and transport all types of wastewater together, irrespective of the initial source. This led to difficulties in handling the peak flows in times of heavy rainfall and to the introduction of combined sewer overflows, which discharged polluted water to surface receiv

43、ing waters. Although many drain and sewer systems started out as combined systems there are arguments for considering the separation of foul wastewater and surface water. The pollutant effects are not the same and the separation of effluents allows for the different treatment for each element of was

44、tewater, providing more environmentally friendly solutions. This concept is included in the approach of integrated sewer system management. EN 752 provides a framework for the design, construction, rehabilitation, maintenance and operation of drain and sewer systems outside buildings. This is illust

45、rated in the upper part of Figure 1. EN 752 is supported by more detailed standards for the investigation, design, construction, organisation and control of drain and sewer systems such as those listed in the lower part of the diagram. This standard is one of a number of standards which support the

46、general principles set out in EN 752. The relationship between these standards is illustrated in Figure 1. DIN EN 13508-1:2013-01 EN 13508-1:2012 (E) 6 Figure 1 Relationship between EN 752 and other drain and sewer standards DIN EN 13508-1:2013-01 EN 13508-1:2012 (E) 7 1 Scope This European Standard

47、 is applicable to the investigation and assessment of drain and sewer systems outside buildings. It is applicable to drain and sewer systems, which operate essentially under gravity, from the point where the sewage leaves a building or roof drainage system, or enters a road gully, to the point where

48、 it is discharged into a treatment works or receiving water. Drains and sewers below buildings are included provided that they do not form part of the drainage system of the building. This part of this European Standard specifies general requirements for the investigation and assessment of drain and sewer systems outside buildings. 2 Normative references
