Maasvlakte 2: Blockbuster reaches main land building hard sea wall

December 30th, 2011 by nwp

Construction of the hard sea wall that is to protect the north side of Maasvlakte 2, proceeds steadily. The ‘wet’ activities underwater were completed in November. In the meantime the specially constructed land-based crane, the Blockbuster, continues to work briskly on the block dam (black line on photo above) that will reach the mainland in mid-February. The coastal expansion project by the Rotterdam harbor is right on schedule.

Large scale dredging completed
PUMA – the joint venture involving Boskalis and Van Oord – started the Maasvlakte 2 project for the Rotterdam Port Authority in 2008. The first phase of the project encompasses 700 hectares of new land for the port.

In 2011 the large-scale spraying of sand from the sea was finished and the first 500 metres of deepsea quay were delivered. The new dunes were finished, roads and viaducts were constructed and work was done on the infrastructure for utilities.


The Blockbuster crane is buidling the hard sea and is now reaching the main land.

In the second phase PUMA will build the quays, roads, railways and bicycle paths. The harbor basins will be deepened to 20 meters below NAP (Normal Amsterdam Level) so that even the largest container vessels can moor there.

Final closure from the sea
In April 2012 PUMA will deliver the hard sea wall which is part of a 11 kilometers long new coastal defense structure.

In July 2012 the gap in the sprayed sand dam will be closed, and at the start of 2013 the connection between the Yangtze harbour and the new port basins will be cut through.

Well over halfway
After three years of construction and less than two years until the first ship berths at the quay, the construction of Maasvlakte 2 is well over halfway. While 2011 was mainly concerned with distances and volumes, 2012 is the year in which everything comes together.

Construction of container terminals
The seawall will be closed and the infrastructure connected so that access for shipping can be opened via the Yangtze harbour. Both customers – RWG and APM Terminals – will be building their terminals in 2012 for occupation in 2014.

Maasvlakte 2 is the largest hydraulic engineering project in the Netherlands since the Delta Project and the construction of the present Maasvlakte.

PWN Technologies to build its largest SIX/CeraMac plant in Andijk, the Netherlands

December 30th, 2011 by nwp

PWN Technologies can start construction of the innovative pretreatment plant Andijk III for drinking water production in Andijk, the Netherlands. The local authorities have recently granted the building permits.

The plant is expected to be operational by the end of 2013, requiring an investment of nearly 50 million euros. PWN Technologies is responsible for the construction and the commission is by the public water supply company PWN North Holland.

Suspended ion exchange and ceramic membrane
The new pre treatment process for surface water developed by PWN Technologies, is based on suspended ion exchange (SIX) and ceramic membranes (CeraMac). This new treatment process will produce water of a better quality, but will also have a lower energy consumption (30%) and lower environmental load (using a natural resin instead of ferric chloride sulfate).


The first ceramic membrane pilot installation in 2008 at Andijk.

Comparison with polymer membranes
The use of a ceramic membrane compared to a polymer membrane has various advantages. Besides a longer lifetime almost any chemical can be used in combination with the membrane, making it possible to clean it with almost any thinkable cleaning regime. The strength of the membrane also makes it possible to use extreme backwash pressure without damaging the membrane and risking an integrity breach.

Although ceramic membranes are perceived to be more expensive than polymeric membranes, their longer life expectancy results in comparable membrane operational costs.

Existing plant outdated
The existing water treatment plant in Andijk which was built in 1968 has become outdated. The current plant requires replacement within a few years in order to guarantee a continued drinking water supply for North Holland in future decades.

Furthermore, the current plant’s capacity is insufficient for future requirements. The capacity of the current plant is 3,200 m³ per hour; Andijk III will have a capacity of at least 5,000 m³/h.

International interest
There is a great deal of international interest in this project. At the Singapore International Water Week in July 2011 PWN Technologies announced the building of a ceramic membrane demonstration plant for the Singapore water board PUB at its Choa Chu Kang plant.

Arcadis to supervise construction of water supply network in Oman

December 23rd, 2011 by nwp

The engineering firm Arcadis announced that it won a large contract to provide consultancy and management services to oversee construction of a new water network for Oman’s Public Authority for Electricity and Water (PAEW). When complete, the network will bring clean water directly to the taps of hundreds of thousands of residents in the Al Sharqiyah region.

Ending water supply with trucks
The project will eliminate the need to truck water from filling station outposts to residents, reducing PAEW’s carbon footprint as well as noise and traffic pollution. The three-year, multi-million dollar contract is scheduled to begin in January 2012.

Growing water demand
The water conveyance system is intended to support the region’s growing population and the development of a future planned shipping port in the region that will further bolster Oman’s economic growth. Arcadis will work closely with the PAEW and contractors to safely address the challenges of the region’s rugged terrain, meeting the fast-tracked project schedule on time and within budget.

Delicate balance of natural resources
“Arcadis will use its global expertise of finding solutions for groundwater depletion to bring clean, reliable drinking water to the region for what will be the first time for many residents, all while maintaining the delicate balance of development requirements and natural resources. We will share Arcadis’ knowledge and skills with PAEW in order to help sustain these projects over the long-term and meet Oman’s goals of improving the country’s infrastructure,” said Arcadis water director Bill Dee.

This news release was originally published on the website of Arcadis.

Dutch experts helped Thai authorities to combat Bangkok floods

December 19th, 2011 by nwp


written by Jac van Tuijn

“Not re-active but pro-active, that’s the way we have assisted the Flood Relief Operations Center in Bangkok”, recall Adri Verwey and Tjitte Nauta of the research and specialist consultancy institute Deltares for coastal areas and river basins.

Initially the two Dutch flood experts were asked by chief of operations for evacuation and flood prevention, minister Plodprasop, to advise him and his staff only.

But as the flood crises intensified late October and Bangkok came under serious threat, more Thai authorities were involved. Verwey and Nauta saw their advisory role expanded to more ministries and other authorities such as the Royal Irrigation Department and the Bangkok Metropolitan Authority.

Verwey was frequently asked to attend top level meetings with the army staff and prime minister Yingluck Shinawatra.

Both flood experts look back on a very successful mission……

What has been your main role in the flood center?
“Right from the start we have worked with our Sobek hydrodynamic simulation model. It enabled us to predict the consequences of rising water levels around the city and possible dike breaches. The Sobek models had been used before in Thailand on earlier occasions of the floods.

By using this data we could show the people in the flood center what to expect as the water levels increased. The model produced maps that made the flooding very visual and allowed the disaster experts at the center to anticipate on possible events and talk about measures to prevent new floods to happen.

When we arrived in mid-October, the center was mainly busy reacting to the floodings that had occurred. Due to our presences they were also able to prevent more damage to happen.”

What else did you do?
“Once we had the Sobek simulation operational, we focused on the dike inspections. We went out and found several dike sections that were weakened by piping. Seepage water was coming underneath the dike and destabilized the foundation. Piping is known as a very serious threat, causing a dike breach.

At one location the piping was very severe and we made a simulation in our Sobek-model. We showed this to the people at the flood center. After a consultation with the prime minister Yingluck, 1000 soldiers were ordered to immediately enforce this dike with sand bags.”

“Our simulation also showed that at the north side of the town, the flood defenses were not high enough and by inspecting the place it was discovered that water was already flowing in. We advised the operation center in a plan for a 6 km long dike made of big bags filled with sand.

After the dike inspections we turned our attention to the pumping stations and advised on the most efficient use of the available pump capacity to keep the inner city of Bangkok as dry as possible. ”

What do you advice the Thai government for preventing this to happen again?
“The Thai Government has some idea of the structural measures they need to take. They, however, should opt for an integrated water management plan that also includes the non-structural measures like institutional reform, flood forecasting and improved land use.

Such a plan should have a broader scope than flood related measures only and should include for instance urgent issues as coastal erosion and deteriorating water quality as well. The Thai government must make a clear choose between ‘quick & dirty’, following the usual ad hoc engineering approach, and a comprehensive long term approach.

Such a new approach would pave the way to a more safe and sustainable Thailand.”

WWTP Dinxperlo turned into public water garden with latest Nereda water treatment technology

December 19th, 2011 by nwp

Water board Rijn & IJssel signed a contract with engineering and consultancy firm DHV to replace its outdated waste water treatment plant Dinxperlo by a completely new one, using the energy and space saving Nereda technology. The contract represents a value of approximately 8 million euro.

Upgrading of former landfill site
Construction of the new plant will be integrated in the Brüggenhütte spatial plan in which the water board and municipality of Aalten are jointly turning a former waste disposal site into a public water garden and green area.

Smaller footprint and energy saving
The selection of the Nereda technology enabled the water board Rijn & IJssel to build an efficient new plant, requiring a far smaller footprint. Philip Schyns, project leader at the water board: “Besides needing less space, this technology will enable us to save energy and costs in the longer term. These advantages have knock-on benefits for efficiency and the environment.”

The strength of the Nereda technology lies in special bacteria that grow in concentrated and fast settling granules. Conventional methods of treating wastewater use bacteria in fluffy flakes, which take much more time to separate from the treated water.

Attractive water garden
The water board attaches importance to corporate social responsibility, efficiency (particularly energy efficiency), sustainability and cooperation. There is close collaboration between the water board and Aalten municipality to create an attractive area in tandem with construction of the new treatment plant.

The Nereda-treated wastewater is going to flow into attractive parcels of water and reeds through a public water garden.

DHV board member Piet van Helvoort states: “Internationally this technology is regarded as a breakthrough in wastewater treatment and the expectation is that the technology will become the new global standard.”

State-of-the-art: aerobic granular biomass
Nereda is an innovative state-of-the-art 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.

The first full scale Nereda installation for municipal waste water at WWTP Epe, the Netherlands, it finalizing commission soon. A number of demo installations with Nereda technology for municipal wastewater is already operational in the Netherlands, Portugal and South Africa. For the treatment of industrial waste water, several Nereda installations have been commissioned since 2006.

Royal Haskoning completes contribution to New Orleans new flood defence system

December 18th, 2011 by nwp

On 8 December, the engineering firm Royal Haskoning celebrated the completion of its activities for the famous Hurricane & Storm Damage Risk Reduction System program. The Dutch Consul in New Orleans, Constance Willems, was also present at the event, which was held with local partner Evans and Graves. Willems praised the company for deploying Dutch coastal defence expertise in New Orleans.

Design of IHNC surge barrier
In recent years Royal Haskoning has been involved in designing the New Orleans levee system, including construction of the Inner Harbor Navigation Canal (IHNC) barrier.

The IHNC barrier seals New Orleans off from the Gulf of Mexico when a hurricane strikes. Royal Haskoning specifically worked on the design height, wave forces, navigation and soil protection. It also advised on and gave direction to the resiliency of the design.

Forecast of hurricanes
Besides working on the IHNC, Royal Haskoning developed concepts for storm forecasting. One of these was the Storm Atlas, which was used effectively in 2008 for efficient prediction of the path of Hurricane Gustav. More recently, the tool has been extended to low intensity storms, enabling the Atlas to forecast a broader range of hurricanes.

Levee information management system
Furthermore, Royal Haskoning has contributed extensively to the system’s operational aspects. It has set up various operational water control plans for the US Army Corps of Engineers. It has also devised a Levee Information Management System (LIMS) for the levee boards. LIMS contains information on the whole levee system, with a visual display function.

Opening and closing of levee floodgates
A special LIMS module has been developed to monitor the opening and closing of the levee floodgates.

This new monitoring system helps the levee boards to plan and coordinate the opening and closure of the gates. Last hurricane season, this module was successfully applied during Tropical Storm Lee.

Giuseppe Miserendino, Director of one of the levee boards, explains “Royal Haskoning staff have a full grasp of our work and the flood protection system, which has resulted in a tailor-made solution that fully suits our needs.”

Making New Orleans a safer place
Resident Director Maartje Wise: “We are very proud to have worked with the US Army Corps of Engineers on the Hurrican & Storm Risk Reduction System and our contribution to make New Orleans a safer place.

Involvement of many
Many interested visitors from the Netherlands and elsewhere came to see the works in New Orleans while the project was in progress. The project triggered students’ imaginations. Marten Hillen, one of the students from Delft University of Technology and now working for Royal Haskoning, was actually awarded “student of the year,” early in 2008, for his work on the project.

Local enterprises hold key to low cost water supply in developing countries

December 18th, 2011 by nwp

To be able to upscale the low cost water supply in developing countries through so called non-piped interventions, it is important to raise awareness amongst potential consumers and to incubate a set of local enterprises that can copy the best local approaches, for instance the sale of water treatment devices, the servicing of a pumping place or a water kiosk. Such efforts cannot be borne by private players alone, and should be supported by philanthropic and public institutions.

This is one of the main outcomes of the study ‘Access to safe water for the base of the pyramid’ done by the Dutch water aid foundation Aqua for All, the foundation BoP Innovation Center and the consultancy firm Hystra.

The study on alternative low cost water supplies in developing countries, started with the identification of some 140 projects across the world and the interviews with 110 entrepreneurs, development specialists and water experts.

Four major clusters
This lead to the identifications of four major clusters:
- flacks & tabs – household purifying filters, tablets or chemicals
- pumping & harvesting – groundwater extraction and rain water collection
- plant & kioks – mini water treatment plants
- pipes & taps – a distribution system and a local operator
Finally 15 cases were selected and analysed in depth.


The scope of safe water solutions, in terms of appropriateness and
cost-effectiveness

Piped networks for urban areas
The in depth analyses of the cases learned that scaling-up access to safe water and reaching out to the 2.1 billion people without this common good is possible, and can even be profitable. For the fast growing urban population in developing countries – expected growth: almost 70% by 2030 – piped distribution networks seems to be the most appropriate.

Hybrid water utilities
Good opportunities lay ahead for utility operators (public and private), especially if they join forces and create hybrid water utilities formed by public, non-profit and private players. These partnerships can focus exclusively on serving fast growing communities in towns and slums of large cities.

The urban areas could be served with relatively low capital investments. For different reasons, such hybrid utilities could not be purely public or private, but rather require a blend of both, in terms of governance and financing.

Water kiosks for rural areas
For rural areas and areas where water is brackish/heavily polluted, other water solutions are better. The Hystra Project Team could identify successful individual projects, but the challenge is to develop – on that basis – entire industries to provide safe water for the poor and “to incubate many local enterprises that can copy the winning approaches”.

Scaling-up by private players alone
For areas with brackish/heavily polluted water there are plenty of opportunities for social entrepreneurs that can run mini-water-treatment stations (kiosks).

Scaling-up in rural areas can be realized by private players alone, but support from public and philanthropic institutions is needed to accelerate.

Acceleration of BoP-focused water industry
Extrapolating from the case study data, the Hystra Project Team estimates that over 6 billion US dollars will be needed to accelerate the development of BoP-focused safe water industries across all clusters. About one third of this amount would come from grants, while the rest would consist of loan and equity financing. Similarly, considerable financial innovation will be needed to create the right incentives for more corporates and investors to come in.

Water company Dunea and polder board Rhineland start five year water project in Mwanza, Tanzania

December 18th, 2011 by nwp

In January 2012 Dutch drinking water company Dunea and polder board Rhineland start a joint project in Mwanza, Tanzania. The European Union has granted one million euro.

New water installations
Mwanza is Tanzania’s second largest city. The city is entirely dependent for its drinking water from Lake Victoria. The local water company Mwauwasa recently completed the construction of new drinking water and waste water treatment installations.

Technically the installations work good, but the knowledge and organizational level of the local authorities, the water company Mwauwasa and the Lake Victoria Basin Water office administrator local water (LVBWO), are a problem.

Transfer of knowledge
The new project focuses on a ‘water partnership’ for transferring expert knowledge from colleague to colleague. The knowledge transfer concerns the entire water cycle: catchment, treatment, distribution, customer service, sewage and resource management (water quality).

The projects runs for 5 years and will be carried out mainly by Dunea. Polder board Rhineland is responsible for delivering manuals for waste water treatment plant and for combating eutrophication of surface waters.

This press release was originally published on the website of the polder board Rhineland (in Dutch only).

Eco landscaping: Waterboxx greens Jordan’s desert areas

December 13th, 2011 by nwp

AMMAN – An initiative that seeks to increase the Kingdom’s green cover by utilising an “intelligent water incubator” that produces and captures water from the air through condensation and rain, will be launched soon in Jordan.

The initiative will be implemented by several local NGOs in partnership with Desert Tulip, a Dutch-Jordanian company, through the Ministry of Agriculture, according to Michael Schuring, general manager of the company.

“The idea is to help increase the green areas in Jordan and acquaint NGOs, farmers and concerned people with the new technique called Groasis waterboxx,” he said in an interview with The Jordan Times last week.

The campaign entails planting saplings in desert areas using the Groasis waterboxx, which was created by Dutch inventor Pieter Hoff.

The device is an “intelligent water battery” that produces and captures water from the air through condensation and rain. The condensation is caused by artificial stimulation and the water is captured without using energy, according to Schuring.

“The Groasis waterboxx makes it possible to plant trees, bushes or vegetables on rocks, on mountains, in gardens, in ashes of recently burned woods, eroded areas or deserts or any other place, without the help of irrigation with good planting results,” he added.

Several farmers in Jordan already using the technology have given positive feedback, Schuring noted.

Abduallah Khudruj, who used the device in his farm in Jerash, said the results were “promising”.

“For each sapling, I usually use more than 20 litres of water every 10 days, but after I used the device in my farm in Jerash, I used only 10 litres of water in 90 days to irrigate one sapling,” he told The Jordan Times on Sunday.

“This is a very good technique that will help farmers a lot. It definitely helps reduce water consumption. There is a water shortage in Jordan and inadequate rainfall… with this device farmers need not worry any more,” added Khudruj, who also owns farms in Amman and Mafraq.

“It is efficient, but our main reservation is about the price. It is a modern solution, but costly. The cheaper it is, the more farmers will use it,” he said, noting that it can help Jordan save water.

Several of these devices have been used in different parts of the Kingdom, according to Schuring, who noted that the Royal Botanic Gardens and the Jordan University of Science and Technology have already tested it and shown interest in using it in different parts of Jordan, he added.

“I am optimistic that it will help Jordan reduce water use and grow plants in desert areas,” he said, noting that the technology is used in over 25 countries, including Ecuador, the US, France, Spain, Morocco, Mongolia, India and Kenya.

“Water is everywhere in the air and this technique is about how to get rain out of the air. It can help grow trees in even the most arid areas, which can help increase the green cover in Jordan without using any water for irrigation,” he added.

The Groasis waterboxx was awarded the Dutch Bèta Dragons Science Award in 2008, and in 2010, it received the Green Tech Award from Popular Science, an American magazine with over three million readers, as well as the “Best of What’s New” award, according to its website.
