European foreword
The present Workshop has been proposed by the E4Water consortium, which is conducting a
Collaborative Project on Economically and Ecologically Efficient Water Management in the
European Chemical Industry (E4Water; www.e4water.eu) [1]. E4Water is supported under the
7th Framework Programme of the EU, Theme NMP.2011.3.4-1, Eco-efficient management of
industrial water.
CWA SustainWATER was developed in accordance with CEN-CENELEC Guide 29 “CEN/CENELEC
Workshop Agreements – The way to rapid agreement” [2] and with the relevant provisions of
CEN/CENELEC Internal Regulations - Part 2. It was agreed on 2016-03-23 in an online meeting
by representatives of interested parties, approved and supported by CEN following a public call
for participation made on 2016-01-22. It does not necessarily reflect the views of all
stakeholders that might have an interest in its subject matter.
CWA 79 SustainWATER is a technical agreement, developed and approved by an open,
independent Workshop structure within the framework of the CEN-CENELEC system.
CWA SustainWATER reflects the agreement only of the registered participants responsible for
its content, and was developed in accordance with the CEN-CENELEC rules and practices for the
development and approval of CEN/CENELEC Workshop Agreements.
CWA SustainWATER does not have the status of a European Standard (EN) developed by CEN
and its national Members. It does not represent the wider level of consensus and transparency
required for a European Standard (EN) and is not intended to support legislative requirements
or to address issues with significant health and safety implications. For these reasons, CEN are

Introduction
This CWA aims to provide guidance primarily for company stakeholders to support
implementation of sustainable integrated water use and treatment. While the whole procedure
might be relevant for some stakeholders, only parts might be for others. Such sustainable
integrated water system is essential for an efficient water use and treatment in any plant,
including chemical and process industries. In its most advanced form it can also be described as
an integrated industrial water management or even as an integrated water management when
urban and industrial waters are managed together. This industrial approach has various
dimensions starting from measures directly linked to single production processes up to
measures and cooperation that go far beyond one industrial unit or even site. With an increasing
range of scale to be considered in the industrial water management, the number of actors to be
involved is growing (e.g. neighbourhood industrial sites, municipal wastewater treatment units,
water resources management institutions up to catchment scale) and technology options are
getting manifold. So there is a clear need to consider them in an integrated way.
To improve the management of water resources, water uses and final effluent disposal, for the
companies in the chemical sector, multiple drivers exist. In many cases more than a single driver
applies for each company, and frequently inter correlation between different drivers exists.
Companies located in water stressed areas (as assessed by various neat tools developed over the
past years) will definitely identify the risk from various sides to reduce their water footprint by
reducing the fresh water intake. Minimizing discharge to sensitive water bodies, not already
regulated by local legislation implementation of the Water Framework Directive is also an
important driver since it will require measures to ensure “good ecological quality” in each river
water basin throughout Europe by 2027 latest.
Where competition with other users exists, typical governance foresees prioritization in water
distribution where the industrial activities will come after, respectively, citizens and agriculture.
The industry can look for alternative, although usually more expensive, water sources or it can
reduce its dependency on fresh water. The latter can reduce in a sustainable way the risk of
disruption in production. Moreover, the likelihood to see a pricing increase in such areas is a
high risk, enhancing the pay back of water reuse.
Anticipating these developments many companies, ranging from SME’s to multinationals, have
included sound water management in their corporate and business strategies. Many have
already defined clear objectives in setting targets for managing their water resources and some
have applied tools to assess their sustainable water use in the expectation that taking voluntary
action at an early stage provides the operating flexibility to achieve these goals when new and
strict legislation is issued.
The overall process to move towards a sustainable integrated industrial water use and
treatment can be described in the following way:
1. Clear definition of the conditions for implementation:
a. Intention, drivers, issues to be addressed.
b. Identification and description of the detailed non-technical framework to be considered,
