TVVL has chosen the meta theme ‘Beyond Smart Cities’ for 2016-2020, in 2017 the focus will be on WATER.

Worldwide many people are choosing to live in cities, for different reasons, living relatively close together on a small area of land. The city needs to be set up in a clever and compact way. Not only as far as planning goes, but also regarding safety, nutrition, energy, water, waste stream, etc.

A smart city is a city where people live together in an energetic way, creating and applying their own solutions. For example; enterprising people, using smart technology can create a more efficient system of supply and demand for the use of renewable energy.

Apart from being smart, a compact city offers advantages regarding the preservation of the environment. Efficient use of available space will reduce running costs of, for instance, infrastructure, drainage, etc. A change in human behavior in these developments is essential.

TVVL will be involved in the development of the smart city. Because of the WATER theme in 2017, the TVVL Expert Group Sanitary Techniques has put two important items on the agenda.

In 2017, the WATER year, the TVVL Expert Group Sanitary Techniques has succeeded in bringing the

International symposium ‘Water Supply and Drainage for Buildings’(W062) of the

International Council for Research and Innovations in Building and Construction (CIB)

to the Netherlands. Universities and knowledge institutes from for instance, Belgium, Brazil, China, Germany, Japan, Portugal, Slovakia, Slovenia, Taiwan, UK, USA take part in this annual symposium.

The coordinator CIB-W062 is prof. dr. L.B. Jack, Heriot-Watt University, Edinburgh (UK).

The 43rd symposium ‘Water Supply and Drainage for Buildings’(WO62) will be held from 23-25 August 2017 in Haarlem.

On the eve of the start of the symposium (22 August 2017) a press conference will take place. During the press conference the winners of the Student competition ‘Uniting Water: which steps for smart cities?’ will be announced. The winners will give a short presentation of their entry.

Explanatory note about the subject choice for the Student competition

The TVVL Expert Group Sanitary Techniques asked the Task Force Water Chain* to give a presentation about “Uniting Water”: ‘Long term vision of the Water Chain’ (enc. 1) and ‘Route Description Innovation Water Chain’ (enc. 2), during the TVVL Technology Day 2009.

In 2012 TVVL participated in ‘Uniting Water in a changing practice’ (enc. 3). In that essay it says that TVVL expects that the sketches of the ‘water chain of the future’ show a much too complicated system. For TVVL the most critical and practical aspect of a project is whether it can be managed and serviced. At TVVL we are of the opinion that we are already unable to properly manage and service what we are creating, many innovations are doomed to fail. We need to keep it simple, history has thought us that.

Innovations need to be simple or sought in sturdy, smart solutions.

Quote from the essay: “Making things simple is what Aristoteles interprets as phronesis: practical wisdom. Today we tend to make things complicated which makes us vulnerable.” Therefore, the question is:

Which steps can contribute to a smart, easy to manage, water chain which is part of a smart city and what do those steps mean for sanitary installations in buildings?

The TVVL Expert Group Sanitary Techniques aims to keep drawing attention to “Uniting Water” and wants to take an active part in developing a smart water chain, both on infrastructural and building level. In order to realize that, an integral construction process is needed, as well as an integrated approach to the development of the water chain outside buildings. The installation sector has to work on contact with the water sector, beyond the building perimeter.

Strange, the way the water sector works; drink water to the building and waste water from the building to the waste water chain. The installation sector closes the water chain in buildings by connecting sanitary appliances to mains and placing drains. Still, the sectors hardly know each other.

The student competition “Uniting water: which steps for smart cities” can help shape the developments towards an integral approach by answering the question which steps are necessary for a smart and simple to manage water chain in a smart city and what these steps mean in relation to sanitary installations in buildings.

The competition

MA students currently in University or those who have already graduated can take part in the competition. Participation is on condition that they can prove by their project report, study report or investigation report that they have innovative ideas regarding the water chain which are aimed at simplicity or sturdy, smart solutions.

All entries will be assessed by the jury, taking originality and the level of innovation into account.

The jury consist of:Prof. dr. ir. Grietje Zeeman (WUR), (chairman) Dr. ir. Govert Geldof (task force water chain) Prof. dr. Ir. Francois Clemens (Technical University Delft) Prof. ir. Peter Luscuere (Technical University Delft)

Participants can enter their ideas, including a short description and a motivation why they think they qualify for a place in the competition finals. Entries should be sent to TVVL, attn. Mylenne Hamaker, m.hamaker@tvvl.nl, before 15 December 2016. The jury will announce on December 2016, which three candidates take part in the finals. The three selected finalists hand in their worked out ideas to the jury on 15 May 2017.

Following a presentation by the three finalists, (PowerPoint should be provided in Dutch and English) the winners will be announced during a press meeting in the Frankrijk room of the Van der Valk Hotel in Haarlem, on 22 August 2017. 1st prize €7.000, 2nd prize €2.000, 3rd prize € 1.000

In 2008 the Task Force Water Chain drew up a vision called “Uniting Water”. This vision gives descriptions of the house of the future, the new housing estates, the restructuring of existing urban areas and the relation between rural and urban areas.

Uniting Water - Long term vision water chain (2008-2050):

'In the Netherlands every household draws top quality drinking water from the tap. The collection and purification of our wastewater happens automatically. Public health is paramount and guaranteed. This is invaluable. We have a system to be proud of.

However, we want more from our system. Here, the human factor is a central issue. We want to design a more flexible system where we are better able to accommodate new insights and innovations. We also aim to make the system more sustainable by implementing the principle of cradle to cradle in the water chain. This means that waste flows are separated at the source and are processed into new products and that we produce energy from wastewater. By practicing cradle to cradle, water quality will not suffer from the use of water.

We would like to increase comfort for inhabitants, by for instance using water as energy carrier and by making a contribution to a clean and green environment, abounding in water. This only possible when rainwater remains clean before being transported to a pond or nearby surface water. Moreover, we would like to innovate and develop new techniques which can also be used abroad. In this way we will be offering solutions for global issues regarding clean (drinking) water and sanitation.'

Uniting Water in a changing practice (2012)

In 2008 the water chain task force drew up a vision called “Uniting Water”. With “Uniting Water in a changing practice” the task force makes the connection with today’s practice (2012).

‘What we are showing in the vision won’t just happen automatically. We can also ask ourselves if the picture we have sketched of the future is a realistic one. In the essay many people were heard. They shared their experience. These people look towards the future, but often trip over the present. Even so, progress is made, lessons are being learned. That is the central theme of this essay. Philosopher Hegel once said: “The only thing history teaches us, is that history doesn’t teach us anything”. We want to leave that behind. The aim is to know the past, understand the present and shape the future. In order to move forward, we need to know what went on and what goes on. This information is a part of the stories that people tell. The more active you are in sustainability and innovation, the more you will recognize people’s experience and the more wisdom you will gain from them. We hope that people from different backgrounds will understand each other better through this essay and that they will actually start working together, however difficult that may be. This is about people after all. We hope that the successful examples that we were able to show, will be an important source of inspiration. '
