1 General
This European Standard specifies the performance, design, operation, maintenance and installation with related verification and test method for positive pressure driven sewerage systems outside buildings carrying wastewater.
It does not provide for the evaluation of conformity of systems to this European Standard. It does not specify the detail design or materials of construction of individual components within the system.
This European Standard covers positive pressure sewerage systems designed for transporting wastewater, defined as: Domestic sewage arising from dwellings and commercial properties but excluding stormwater and rainwater.
This European Standard covers the design of a PSS and some requirements of products used together with the PSS in order to ensure the performance of a PSS.
The components of the system and in conjunction with the system should be evaluated by reference to the appropriate product standard. In the absence of a product standard, this standard may be used as a reference for drawing up a specification for that product.
2 Limit of design
Intermediate pressure booster equipment is not covered in this standard.
The use of compressed air as the only means of generating pressure is not covered in this standard
The design requirements of this standard are minimum requirements and do not constitute in themselves a comprehensive design sufficient to ensure a correctly functioning system. Every system must be individually designed. Where proprietary components are employed, account should be taken of the advice of the component supplier.
3 Application of pressure sewerage systems
(PSS)
Information on the use of pressure sewerage systems is given in A.l.
4 Sources of additional information
Documents which, whilst relating to specific systems, contain details which can be used within the framework of this standard are listed in informative annex C.
