Foreword
This document (CEN/TR 15128:2005) has been prepared by Technical Committee CEN/TC 165 “Wastewater
engineering”, the secretariat of which is held by DIN.
CEN/TC 165 having determined the current status of European standardization regarding general
requirements for drain and sewer systems and existing standards and draft standards on the subject of
rehabilitation of drain and sewer systems, and CEN/TC 165 having considered the results of an enquiry
submitted by EUREAU on the status of European Standards in the field of rehabilitation of drain and sewer
systems, it was established that those were not sufficiently known.
It was agreed that information of the status of European standard work in this area was greatly needed.
Therefore, CEN/TC 165 decided to make this information in summary form available with the aid of an
informative CEN document in the form of a CEN/TR and, if necessary, to give the necessary explanations.
Standards produced by the following Technical Committees are included in this document:
CEN/TC 155 "Plastics piping systems and ducting systems";
CEN/TC 164 "Water supply";
CEN/TC 165 "Wastewater engineering".
Because European manufacturers have disbanded the production of fibre cement pipes and fittings for drain
and sewer systems, European Standards in that field are not included in this document.

1 Scope
This document gives a survey of European Standards available in the field of rehabilitation of drain and sewer
systems.

5 European Standards for rehabilitation of drain and sewer systems
5.1 Survey of condition
EN 13508-1:2003, Condition of drain and sewer systems outside buildings — Part 1: General requirements.
Summary: Establishment of the condition of existing drain and sewer systems and its elements outside
buildings, Performance requirements and performance deficiencies are listed.
EN 13508-2:2003, Conditions of drain and sewer systems outside buildings — Part 2: Visual inspection
coding system.
Summary: Specification of a system of codes which shall be used to describe the defects and features
found in drains, sewers, manholes and inspection chambers identified by visual inspection.
Where appropriate, EN 13508-2 can also be used for pressure and vacuum systems in
accordance with the requirements of the employing authority.
5.2 Principles for planning and design
EN 752-2:1996, Drain and sewer systems outside buildings — Part 2: Performance requirements.
Summary: Specification of requirements to be considered when planning, designing, constructing,
operating and maintaining drain and sewer systems operated mainly under gravity. These are
basic performance requirements to which the sewer system shall operate; performance
testing and performance assessment and documentation are included.
EN 752-4:1997, Drain and sewer systems outside buildings — Part 4: Hydraulic design and environmental
considerations.
Summary: Sets out the principles which shall be followed for both the hydraulic design and consideration
of environmental impact of drain and sewer systems that operate essentially under gravity.
EN 752-5:1997, Drain and sewer systems outside buildings — Part 5: Rehabilitation.
Summary: Sets out the principles and procedures for planning and design of rehabilitation works
necessary to achieve prescribed levels of performance for existing drain and sewer systems,
where investigations may lead to structural solutions such as replacement, renovation or
repair. Regarding performance requirements of the rehabilitated system, part 5 indicates that
they are similar to those for a new system (see EN 752-2 and EN 752-4).
EN 805:2000, Water supply — Requirements for systems and components outside buildings.
Summary: Specification of general requirements for water supply systems outside buildings including
potable water mains and service pipes, service reservoirs, other facilities and raw water mains
but excluding treatment works and water resources development. For significant modification
and/or rehabilitation of existing water supply systems EN 805 specifies that for works of repair,
renovation or replacement, the relevant requirements of the standard shall be followed. In
case of repair or renovation, the design life extension may be less than 50 years. Allowable
pressures (PFA, PMA and PEA) are defined. To ensure that pressure classification in ENs for
products (used for water supply and pressurised wastewater systems) will be related to the
allowable pressures as defined in EN 805, prEN 14801 shall be considered.
prEN 14801:2003, Conditions for pressure classification of products for water and waste water pipelines.
Summary: Specifies the installation and loading parameters to be used for the determination of the
allowable pressures (PFA, PMA and PEA) as defined in EN 805, to components (pipes, joints,
fittings, ferrules and valves), which have pressure related classification in European
Standards and which are intended to be used for buried water supply and waste water
pressure pipelines outside buildings.
EN 13689:2002, Guidance on the classification and design of plastics piping systems used for renovation.
Summary: Guidance for defining families of techniques for renovation of non-pressure and pressure
pipelines (for water, wastewater and gas) by use of plastics pipes, fittings and ancillary
components. It provides guidance on the principles of, but not detailed methodologies for, the
design of plastics piping systems applied as linings to existing pipelines, covering: liner
functions; existing pipeline and site conditions; technique related aspects; structural aspects;
hydraulic aspects.
5.3 Product requirements
5.3.1 Product requirements for repair
EN 13380:2001, General requirements for components used for renovation and repair of drain and sewer
systems outside buildings.
Summary: Specification of general requirements test methods for components such as pipes and fittings
with their respective joints, manholes, inspection chambers and materials such as mortar and
chemicals all intended to be used for repair and renovation of drain and sewer systems which
operate as gravity systems where any pressure likely to occur is a maximum of 40 kPa and
which are generally buried.

EN 295-7:1995, Vitrified clay pipes and fittings and pipe joints for drains and sewers — Part 7: Requirements
for vitrified clay pipes and joints for pipe jacking.
Summary: Specification of requirements and test methods for flexibly jointed vitrified clay pipes for pipe-
jacking techniques including micro-tunnelling, pipe- eating, pipe bursting and where
appropriate for slip-lining (i.e. lining with discrete pipes).
EN 1916:2002, Concrete pipes and fittings, unreinforced, steel fibre and reinforced.
Summary: Specifies mandated performance requirements and describes test methods for precast
concrete pipes and fittings, with flexible joints (with seals either integrated in the units or
supplied separately) for which the main intended use is the conveyance of sewage, rainwater
and surface water under gravity or occasionally at low head of pressure, in pipelines that are
generally buried. A separate clause deals with jacking pipes which may be used for lining with
discrete pipes.

systems outside buildings.
Summary: see 5.3.1
EN 13566-1:2002, Plastics piping systems for renovation of underground non-pressure drainage and
sewerage networks — Part 1: General.
Summary: Deals with the general requirements for plastics piping systems used for renovation of
underground non-pressure drainage and sewerage networks common to all relevant
renovation techniques such as lining with continuous pipes, lining with close-fit pipes, lining
with cured-in-place pipes, lining with discrete pipes, lining with spirally-wound pipes. It applies
to pipes and fittings as manufactured as well as to the installed plastics lining system; it does
not cover the requirements of the existing pipeline or any annular filler.
