What Are the Main Options for Applying
the Multiple-Use Water Services
Paradigm?

Abstract This brief asks the question, what are the main options to apply the MUS
paradigm in urban environments? It breaks down the various components and pro-

t analyses for the various components along with challenges and
considerations for both the short and long terms. The brief includes a section on the
MUS approach and a means to calculate the value of MUS systems, as well as
provides tools and resources to support urban blue-green design. Comprised of actual
and potential options for decision makers and policy makers to integrate blue and
green measures that target the optimal synergies between interventions and tech-
niques with the purpose of delivering multiple bene

1 Introduction

An overview of main concepts and techniques for achieving the envisaged MUS
synergy in urban design and management is presented in Fig. 1 and analysed in
detail in the following sections.

2 Wastewater Reuse and Recycling

Wastewater reuse — recycling can be generally de ned as the use of treated water

for several purposes such as toilet flushing, landscape irrigation, groundwater

recharge, etc. Wastewater is a general term for used water that its quality has been
affected from human activities, residential, commercial or industrial. Wastewater is
usually discharged through centralised sewer systems to Wastewater Treatment
Plants for removal or reduction of hazardous substances. Alternatively, wastewater
