WATER DECISION SUPPORT
• Present meaningful information
• Personalized Services
• User Awareness (usage)
• User Incentivisation (Price)
• Benchmarking
– Neighborhood
– Industry Sector

WATER FOOTPRINTS
•  Business transparency
driving assessments of
water impact
•  Water footprints
consider all sources of
water consumption (direct/
indirect)
•  No single data source
•  Requires integrated data
from many participants in
supply chain
– Weather data, geo-location
data, historical records,
product usage data, user
behaviour habits, etc
http://www.waterfootprint.org/

Technology and Data Interoperability
•  Data produced in different organizations
•  Data scattered among different
information systems Dynamic data, sensors,
ERP, BMS, assets databases, …
•  Multiple incompatible technologies make
it difficult to use
•  Significant cost to bring this data together
How do we breakdown these
Water Data Silos?
KEY DATA CHALLENGES

• Emerging data management techniques
recognize expense obtaining upfront
unifying schema across all data sources
Key Emerging Principles
– Co-existence of data without unifying schema
– Loosely integrated set of data sources
– Data integrated on “as needed” basis
– Tighter integration achieved in an incremental
"pay-as-you-go" fashion

abstraction for information management,” Sigmod Record, 34(4) 2005.

•  Linked Data is a method of exposing, sharing, and
connecting data (via de-referenceable URIs) on the Web.
–  Provides a Data (RDF) and Naming (URI) model for the Web
–  W3C Web-based Standards
–  Adaptive Ontologies
–  Incremental Approach
•  Resource Description Framework (RDF)
–  Graph based Data – nodes and arcs
–  Identifies objects (URIs)
–  Interlink information (Relationships)
•  Vocabularies (Ontologies)
–  Provides shared understanding of a domain
–  Organizes knowledge in a machine-comprehensible way
–  Gives an exploitable meaning to the data
LINKED DATA

LINKED DATA PRINCIPLES
1. Naming: Use URIs to identify the “things”
in your data
2. Access: Use HTTP URIs so people (and
machines) can look them up on the Web
3. Format: When a URI is looked up, return a
description of the thing in a structured
format (RDF)
4. Contextualization: Include links to related
things to provide context (data network)

LINKED WATER DATA

•  To introduce demand response and accountability principles
(water footprint) in the water sector
•  To engage consumers in new interactive and personalized ways that
bring water efficiency to the forefront and leads to changes in water
behaviours
•  To empower corporate decision makers and municipal area managers
with a water information platform together with relevant tools and
methodologies to enact ICT-enabled water management programs
•  To promote ICT enabled water awareness using airports and water
utilities as pilot examples
•  To make possible new water pricing options and policy actions by
combining water availability and consumption data
WATERNOMICS will provide personalised and actionable
information on water consumption and water availability to
individual households, companies and cities in an intuitive &
effective manner at relevant time-scales for decision making
