BATHING WATER QUALITY FORECASTING & EARLY
WARNING SYSTEMS
DHI are pleased to announce that we are holding a 2-day
seminar entitled ‘Bathing Water Quality Forecasting & Early
Warning Systems’ in Southampton on 6-7 October 2016.
Bathing water quality is one of the success stories of EU
water policy and is important for the protection of human
health and the environment. The UK has a large number of
designated Bathing Waters governed by EU legislation and
maintaining the water quality at these sites can be a complex
task. Storm events, in particular, can lead to increased
discharges into the local water environment and these can
have unwanted impacts on water quality at the bathing
beaches. Water companies, as operators of emergency
outfalls, and local groups responsible for beach manage-
ment, need to be able to provide sufficient warning to beach
users to avoid public health issues and any potential
subsequent impacts on the local economy.
This two-day, thematic course provides an overview of the most important aspects
of the revised European Bathing Water Directive and gives an introduction to real
life cases of good management of bathing water and different early warning
methods. It will then focus on the benefits of integrating real-time operation with
water quality forecasting. Finally, the practicalities of creating an appropriate
forecasting system for a site, including catchment considerations, network controls
and advanced optimisation techniques will be discussed. Global examples will be
used to demonstrate the breadth of current beach water quality forecasting systems
and to show their strengths in ensuring these popular and precious assets are
maintained to the highest standards.

THE NEXT INDUSTRIAL REVOLUTION: INDUSTRY 4.0
Originally intended by the German Government to spur its
industrial sector, and driven by the convergence of automation
technology and information technology, INDUSTRY 4.0
promotes computer based, intelligent control of complex
systems. It is, in effect, the digitisation of our industrial and
manufacturing processes by so called cyber-physical systems.
INDUSTRY 4.0 advances the embedding of sensors in
virtually all product components and manufacturing
equipment, ubiquitous cyber-physical systems and the
analysis of all relevant data. Connectivity is therefore of
primary importance, and will form the foundations of all future
proof, intelligent technologies.
WATER 4.0: DIGITISATION & AUTOMATION
At DHI, our interest lies in how INDUSTRY 4.0 can benefit the
efficient, flexible and competitive management of water in all
of its environments, driven by intelligent, autonomous and self
-learning models impacting real water systems through
actuators. Hence, WATER 4.0.
By embracing the principles of INDUSTRY 4.0, for example,
our existing drainage infrastructure can be retained and
connected, only partial replacement of devices and equipment
is necessary. This is only possible through the smart, real-time
control and optimisation of our water systems.
The well-established, operational real-time control and
warning system for Aarhus in Denmark, based upon DHI’s
flagship MIKE OPERATIONS technology, has already proved
that the ability to automatically control a wastewater system in
real time, so that the water is transported to where there is
capacity, dramatically reduces the need to invest in enlarging
and upgrading the existing drainage system.
Such model driven, real-time control and optimisation
solutions are available today in MIKE OPERATIONS.
However, DHI are now working to advance new and
innovative numerical methods, together with the knowledge
gained and technology developed for Aarhus, into
standardised and commercially available next generation
tools.
THE KLIMASPRING PROJECT: CONTROLLING WATER IN
THE DRAINAGE SYSTEM
“Klimaspring is a Realdania-funded campaign supporting
commercial development of new rainwater management
solutions in existing densely populated urban areas. The
ambition of the campaign is to create green growth and better
cities, putting Denmark on the world map of climate
adaptation. The campaign provides
professional and financial support to
consortium-driven innovation throughout
the work process from concept to
marketing. Realdania has earmarked DKK
60 million to the campaign, which is
scheduled to run from 2013 to 2017”
In collaboration with Aarhus Vand and DTU, DHI is part of the
Klimaspring project financed by RealDania. The Klimaspring
project is focussed upon the smart, real-time control of water
systems, and aims to further develop the IT-supported system
for the real-time monitoring, modelling, warning and
management of rainwater (in both drainage systems and on
the ground) originally developed for Aarhus. Accordingly, the
project’s primary objective is to make managing rainfall less
expensive.
The new and upgraded technology solution will feature a
number of innovations including; model engine optimisation
through surrogate modelling, enhanced radar data processing,
control algorithm optimisation, improved data and model
integration, and enhanced visualisation. It will have a wide
range of applications in cities and towns around the world.

DHI will deliver this next generation real-time control toolset
through the standard MIKE Powered by DHI software suite, as
part of MIKE OPERATIONS, thereby empowering utility
companies, municipalities and their consultants to develop
their own state-of-the-art operational real-time control
systems.
“The development of the new software is based on the
concept of smart control of water systems. By comparing
information on where the water is at all times, and at the same
time predicting where and how much rain will fall in the
immediate future, it will be possible to find the optimal solution
for the entire city or town’s water system, and in this way
efficiently utilise reservoirs and purification plants”
WATER 4.0: DIGITISATION & AUTOMATION
To help shape the required new technologies, DHI have
established a WATER 4.0 working group to examine the
challenges and benefits of networking virtual and real-world
water systems, and to investigate how planning, construction
and operation can be imbued by software. The aim is to
promote the intelligent networking of water
consumers (agriculture, industry and
households) with components of future-
compliant water infrastructure considering
both the environment and the water cycle,
thereby following a holistic approach along
the value chain.

NEW INITIATIVE PREDICTS WATER QUALITY IN
AUCKLAND’S WAITEMATA HARBOUR
by Rose Jowsey (DHI)
A new joint initiative from international water and environment
experts DHI and local council body Auckland Council has
recently gone online to the public. The Auckland Bathing Water
Forecast (AWBF), has been designed to provide forecasts of
bathing suitability for central Auckland for up to three days.
Recent high test results from some of the monitored beaches
indicate that the innovative system is needed. On February the
27th, the popular North Shore beach of Takapuna was closed to
the public due to poor water quality.
Dr Jarrod Walker, a senior marine scientist from Auckland
Council and one of the main drivers behind the initiative, says the
enterprise is beneficial for planning, "with the model, you can
jump online on a Friday afternoon and see that the beach is safe
now and over the weekend”.
The technical side of the ABWF means data is gathered from a
variety of sources, including Met Service, Auckland Council, and
the National Centre for Environmental Prediction. Tidal and wind
driven currents in the Waitemata Harbour are simulated in a three
dimensional hydrodynamic model, developed by DHI. Key
overflows in the vicinity of central city bathing beaches, which are
a significant source of pollutant to the harbour, have been
identified and a relationship between rainfall and overflows with
associated enterococci has been calculated.
Enterococci is a key indicator for swimmer safety. How the
system works is that during a rainfall event the predetermined
load of pollutant is introduced to the hydrodynamic model of the
harbour and the resulting transport and dilution of the pollutant
plume is simulated. When collated into the model, the data forms
a wide picture for simulating water quality at times of heavy
rainfall, signalling to residents and harbour users when it is again
safe to enter the harbour for swimming and leisure.
Concerned water users can click through to the site and will see
a series of flags. The flags are in accordance with Ministry for
Environment Recreational guidelines with regards to trigger
levels for swimmer safety. The flags will pop up with a window
displaying the water quality. Although the model does not
account for pollutants associated with dry weather overflows or re
-suspension of bacteria laden sediments, it does give residents a
significant indication of whether or not to go for that swim they
were planning after wet weather events.

DHI’S NEW INTEGRATED TECHNOLOGY PROVIDES
IMPROVED RAINFALL MODELLING
In a new study published in Scientific
Reports (Nature Publishing Group),
significant improvements in simulation of
rainfall were achieved by incorporating a
comprehensive description of the terrestrial
hydrological cycle using MIKE Powered by
DHI’s MIKE SHE model.
In collaboration with research partners from Copenhagen
University (KU), Technical University of Denmark (DTU),
Danish Meteorological Institute (DMI) as well as the
Geological Survey of Denmark and Greenland (GEUS), we
have developed a novel climate-hydrology modelling tool that
will better assess the effects of climate change.
NEW PROJECT ‘WATER SMART CITIES’ PROVIDES
WATER UTILITIES AND MUNICIPALITIES WITH BETTER
TOOLS FOR CLIMATE CHANGE ADAPTATION
Intelligent software technologies to ensure optimal planning
and management
Named ‘Water Smart Cities’, the project is a
collaboration between DHI, the Technical
University of Denmark (DTU), Krüger,
Ramboll, the Danish Meteorological Institute
(DMI) and the four largest water companies
in Denmark: HOFOR, Aarhus Water, VCS
Denmark and BIOFOS.
The project aims to develop and test intelligent software
technologies to ensure optimal planning when cities are
challenged by heavy rains and flooding in the future. Thus, the
project partners will focus on developing and producing fast
and robust model concepts for real-time simulation and real-
time control of drainage systems. Forecast models – of floods,
overflows from sewage systems, impacts on recipients, as
well as inflow and pollution to wastewater treatment plants –
will be designed and tested during the project.
The ‘Water Smart Cities’ project is based on the current
project ‘KlimaSpring’, which is carried out jointly by DHI,
Aarhus Water, DTU Compute and DTU Environment. In
‘KlimaSpring’, basic software components for surrogate
modelling and optimisation of the management of drainage
systems are being developed.
BIOFOS APPOINTS DHI TO IMPLEMENT INTEGRATED DATA
INFORMATION AND MANAGEMENT SYSTEM
BIOFOS – the largest wastewater utility in Denmark – has
appointed DHI to deliver a data management system to help
improve the operational efficiency of its wastewater collection,
transport and treatment.
The wastewater utility services 1.2 million people and a large
number of industries in Greater Copenhagen. Wastewater from a
total of eight utility companies in 15 municipalities is treated at
BIOFOS´ three plants. The entire system is connected by large
interceptor sewers and the treatment plants produce more than 50
GWh of energy every year.
In a continued effort to improve its operations,
BIOFOS has taken the first steps towards a
fully integrated system, balancing the loads on
the sewers, plants and receiving waters. This
includes establishing a data integration and
information management system across the
eight connected sewer utility companies and
the three plants.
MONITORING OF WATER SUPPLY THROUGH SIMULATION
AND ACCESS TO REAL-TIME DATA
Founded in 1909 as the municipality of Rome’s
electric company, ACEA is a listed industrial
group and one of the most important national
public utility operators in Italy. Together with
DHI Czech Republic and a local partner, DHI
Italy has helped them develop a WebGIS-
based platform integrating MIKE URBAN to
estimate the operating parameters of their
water networks.
