1. Monday October 30th, from 9.00 - 15.00 h. 
Visit the Marker Wadden, a unique boat tour over the Markermeer Lake 
Natuurmonumenten (Dutch Society for Nature Conservation) and Boskalis Dredging & Marine Experts are going to restore one of the largest freshwater lakes in western Europe by constructing islands, marshes and mud flats from the sediments that have accumulated in the lake in recent decades. These 'Marker Wadden' will form a unique ecosystem that will boost biodiversity in the Netherlands. The Markermeer Lake (700 km2) used to be part of the Dutch Zuiderzee, but is now cut off from the North Sea and rivers by dams, dikes and reclaimed land. The lake has barely any natural shores, and its waters are often extremely turbid as wind and waves churn up the accumulated sediments from the relatively shallow lake floor (2-4 m deep). As a result, fish and bird populations have declined dramatically. The boat tour is especially arranged for the visitors of the AIWW. The tour gives a unique opportunity to visit man-made islands in the Dutch delta.

2. Monday October 30th, from 9.00 - 13.00 h.
Visit Heineken Experience Amsterdam 
Visit Heineken Experience Amsterdam. The Heineken Company recognizes that water is essential for life. Water is also a prime raw material and indispensable for cleaning purposes for the Heineken Company. This excursion offers a unique combination of the Heineken Experience Amsterdam and a presentation by mr. Jan-Willem Vosmeer (Manager Corporate Social Responsibility) of most recent developments of improving the processes of water and waste water as resource. Water is treated as a vital resource by setting ambitious water usage targets and continuously improving these over the years. The wastewater resulting from our processes is treated in the breweries proprietary wastewater treatment plant. The wastewater is treated by anaerobic reactors, thereby producing biogas that is efficiently used for electricity and steam production. The biogas usage reduces the carbon footprint of the brewery. After the anaerobic treatment, aerobic reactors purify the wastewater up to a level that the effluent is discharged directly into the surface water. Please join us at the Heineken Experience Amsterdam and get informed about the most recent development in water treatment initiatives and water based renewable energy projects.

3. Monday October 30th, from 14.00 - 17.00 h.
New city development at Amsterdam-North and new sanitation and energy concepts at Buiksloterham and new self-sufficient local energy initiatives of sixty companies at NDSM wharf 
Amsterdam created at Location ‘De Ceuvel’ a laboratory for new sanitation concepts. It is one of the most sustainable and unique urban developments in Europe for green entrepreneurs and creative programming. The idea of this circular park was developed in 2014 after a group of initiators won a tender to create a regenerative urban oasis on an old shipyard in the north of Amsterdam. In this area people can test innovative sustainable concepts to make a step forward in new energy, re-use, recovery and sustainable solution of water, energy and food. At the former NDSM wharf new concepts made it possible to connect 60 companies in a 100% sustainable energy supply. The combination of new entrepreneurship and cooperation enables Amsterdam-North in becoming a trending settlement for new sustainable energy businesses.

1. Thursday November 2nd, from 9.00 - 12.00 h.
History of the Amsterdam Water cycle: a historical boat tour
The history of the Amsterdam water cycle is fascinating and we celebrate 400 years of canals, 130 years of drinking water supply and a 100 years of waste water management. How has the robust canal city risen from the swamp? How did the city get their drinking water? What is the relation between jerry-building in the 19th century and current groundwater problems? Why has Amsterdam built a separate sewer since 1924? During a boat tour through the canals we share our stories with you about the history and the future challenges of the water cycle.

2. Thursday November 2nd, from 9.00 - 15.00 h.
Visit the Deltaworks and Room for the River Programme main elements; storm surge barrier 'Maeslantkering' and Noordwaard Polder
The goal of the Dutch Room for the River Programme is to give the river more room to be able to manage higher water levels. At more than 30 locations, measures are taken to give the river space to flood safely. Moreover, the measures are designed in such a way that they improve the quality of the immediate surroundings. The Room for the River Programme will be completed this year. During the excursion two locations will be visited. The high standard of water safety constructions of the famous Maeslantkering and the latest developments of Room for the River at depoldering of Noordwaard Polder. The Noordwaard is an area of 4,450 hectares - around 6,000 football pitches - that borders on the Biesbosch National Park in Brabant and the Nieuwe Merwede. In the area’s lively history, nature, water and people alternated in determining the appearance of the landscape. Eliminating the polder increased the safety situation of the downstream area, because the river water can flow in and out of the Noordwaard during periods of high water.

3. Thursday November 2nd, from 13.00 - 17.00 h.
From waste to new resources and energy: Waste Water Treatment Plant Amsterdam-West & Waste to Energy Plant Amsterdam
Climate change, growth of the world population, shortage of raw materials and fast-growing cities lead worldwide to the necessity of changing our behaviour towards water, energy and waste materials: use less, and recycle more on a high level quality. As example of an integrated solution you can visit the largest Waste Water Treatment Plant in Amsterdam (1 million p.e.) in combination with the largest Waste to Energy plant in the world. More than 1.5 million ton of waste and sludge is incinerated at this plant. This is an example of sophisticated, technological and industrial process integration. By recovering and re-using waste, heat and by-products they provide in raw materials for production processes. For delivering the sludge and biogas the WTP receives in return 100,000 MWh/year and heat. This prevents the use of 1 mln m3 natural gas and the emission of 1,800 ton CO2-eq per year. The integration results also in the production of circa 25,000 MWh electricity and 75,000 GJ heat that is distributed for district heating to households. This means a reduction of 285 TJ energy and 15,000 ton CO2.

1. Friday November 3rd, from 9.00 - 15.00 h.
Flood protection in Amsterdam & Rotterdam, vital infrastructure & urban rainproof projects
The flood threat in the Netherlands is related to various possible flood events originating from The North Sea, from the River Rhine delta, from inland lake IJmeer or from the regional water system. In Amsterdam and Rotterdam pilot project concepts are implemented to maintain and improve the safety against flooding in the region on the long term following a multi-layer safety approach. In this approach the focus is not only on prevention (levees), but also on diminishing effects by spatial measures, damage control and evacuation. During the tour several flood prone areas in the cities will be visited. Guides will explain the different flood protection systems - with a specific focus on the protection of vital infrastructure - and possible multi-layer safety measures related to new developments and the historical perspective. This excursion will also show how modern and future ‘smart’ (ict enhanced) flood protection structures can keep Amsterdam safe in an effective, budget friendly and efficient way, with minimal claims on scarce building space.

2. Friday November 3rd, from 9.00 - 13.00 h.
State of the art Waste Water Treatment city Epe with Nereda
Nereda® is an innovative and advanced biological wastewater treatment technology that purifies water using the unique features of 'aerobic granular biomass'. Contrary to conventional processes, the purifying bacteria concentrate naturally in compact granules, with superb settling properties. As a result of the large variety of biological processes that simultaneously take place in the granular biomass, Nereda® is capable of producing excellent effluent quality. Even when not particularly targeted, extensive biological phosphorus and nitrogen reduction is an intrinsic attribute of this technology, resulting generally in chemical-free operation. These unique process features translate into compact, energy saving and easy to operate Nereda® installations for both industrial and municipal wastewater treatment. Nereda® presents attractive new solutions for green field installations and retrofitting or extending conventional activated sludge plants. The technology is also highly recommended for performance and capacity upgrades of existing SBR-facilities. We will visit the world's first full-scale municipal sewage treatment plant using the cutting-edge Nereda technology in the Dutch town of Epe.

3. Friday November 3rd, from 15.00 - 18.00 h.
High technical innovative water purifications at drinking water treatment plant of OASEN 
Oasen is developing a new treatment concept within a five year research program. This treatment concept prepares Oasen to be ready for future challenges such as salination of the ground water and possible upcoming emerging substances in our water source. It aims to produce in a sustainable way drinking water of impeccable quality at reasonable cost. The new treatment concept consists of 100% membrane filtration (RO) followed by remineralisation. In the search for the optimal technology for Oasen an essential part is extensive pilot testing to compare several technologies. Technologies under research are among others anaerobic RO, Ion Exchange, Calcite Filtration, Membrane Contactors and innovative research to the water quality during distribution. 

During this excursion visitors will get an interesting tour at the research facility, where the latest results will be shown and where the future treatment concept is running at pilot scale. Possibly it will combined with a visit of one of Oasen’s newest treatment plants where an RO-treatment step is fully operational.

Oasen is a groundwater company. Groundwater is a combination of surface water and rainwater that has soaked deep–15 to 100 metres–into the ground. It is naturally filtered, but still requires treatment before being suitable as drinking water. The water which Oasen pumps up is primarily surface water which has seeped into the ground through riverbanks. This is called bank filtration. The conventional treatment for this water source is aeration, sand filtration, water softening, active carbon and UV disinfection, which Oasen applies already for decades.
