New storm water catchment concepts

Living Lab Rainshell water concept

Construction of the Rainshell concept and its filter bed of shells and minerals to retain and simultaneously clean the runoff water.

Last week, VP Delta opened a living lab facility for new storm water catchment concepts for a more smart way to handle storm water in cities.

As a result of the expected increase of extreme rainfall events, several Dutch SME-companies developed innovative concepts to handle extreme volumes of storm water and store in underneath hardened urban surface. Read More

Severe drought threatens to run taps dry in Cape Town

How did Cape Town deal with its “Day Zero” water crisis and what can we learn? 
Intense drought in South Africa’s Western Cape Province has led the world-renowned city of Cape Town to the brink of “Day Zero”. Day Zero was the date at which residents would be forced to collect strictly rationed water supplies from shared distribution taps. Read More

The project will serve as an example for many other cities in the Arab region to make the switch from responding to anticipating to a disastrous flood. Read More

Climate Proof Cities

climate proof cities

A quarter of the planet will experience severe water shortages one month per year by 2030.

Cities ​are ​highly ​vulnerable to ​climatic risks. ​Think of heatwaves, water scarcity and extreme rainfall.

What can cities do to become resistant climate proof? Let’s give an overview. Read More

More rain, less snow on Arctic

More rain, less snow on Arctic

According to climate researchers, more rain than snow will fall in the Arctic. Moreover, oceans are getting hotter, and they’re also losing oxygen

According to climate researchers in the Netherlands, at the end of this century more rain than snow will fall in the Arctic. It was already known that, due to global warming, up to 60% more precipitation would fall in the Arctic.

The researchers now argue that it mainly involves rain, while scientists always presuppose the precipitation would be snow. Read More

Cape Town is running out of water

Cape Town is running out of water

Helicopters release water bombs to stop the wildfire but they are afraid to use salty sea water because that damages the vegetation.

Cape Town, South Africa is running out of water. The city has been struck by severe drought and there is enough water for just 100 days.

Just like Sao Paulo in 2015, citizens are asked to conserve and reduce their water supply. Kevin Winter, lecturer at the University of Cape Town Environmental and Geographical Sciences: 

“We can’t see any rain on the horizon. And right now, in terms of dam storage levels, we’re probably approaching the ‘100 days left of storage.

Water Scarcity: 3 strategies for cities

Water Scarcity biggest problem

Pakistan is already vulnerable because of the different ethnic groups and religions. Also the country is one of world’s 36 most water-stressed countries and the situation gets worse. A civil war is not inconceivable

Scarcity of fresh water is the biggest world problem according to the Nature Conservancy. A lot of cities suffer under water stress. 

A quarter of the planet will experience severe water shortages one month per year by 2030.

The Nature Conservancy is working on a variety of strategies to protect water at its source, increase water efficiencies, and engage corporate and municipal leaders, governments, urban residents and other institutions in watershed stewardship. They offer 3 strategies Read More

Storm Axel worst German flooding in decades

The port city’s historic fish market, which lies directly on the harbour, was filled with knee-deep water, while cars and busses driving along the water front flooded through the high tides.

Flooded streets and basements, cars underwater, dams overwhelmed – storm Axel brought great damage to parts of the Baltic coast in Germany last Wednesday.

The northern states of Germany had to survive a hurricane force storm; the worst flooding in eleven years.

Reduce risks storming water

The US President has declared a federal disaster for the storms and floods that struck 8 counties of Iowa during late August 2016.

Storming Water costs lives and a lot of money. Last winter, more than 15,000 homes and businesses in just eight council areas in the USA were flooded, a survey has revealed.

In October, the US President has declared a federal disaster for storming water and floods that struck 8 countries during late August 2016

The research for the Local Government Association found that councils were still helping flood-hit homes recover.

Councils are encouraging people to check if they are at risk of flooding this year, to sign up to flood warnings and make sure their homes are prepared. Read More

20% of the world’s population will migrate by sea-level rise

Sea-level rising: populations at risk

Even if global warming is capped at 2C, 20% of the world’s population will have to migrate away from coasts swamped by rising oceans. 

Even if global warming is capped at governments’ target of 2C, 20% of the world’s population will be to migrate to higher area’s because of rising sea levels.

Countries like the Netherlands and Bangladesh and cities including New York, London, Rio de Janeiro, Cairo, Calcutta, Jakarta and Shanghai would all be submerged because of melting polar ice caps and sea-level rise. Read More

SF needs to speed up to climate change

SF needs to speed up to climate change

SF doesn’t know which neighborhoods will be worst hit after a given storm, but they do know sea levels are rising, and that with climate change, those hurricanes off Mexico’s Pacific Coast could come north some day. They don’t know when or how severe, but we could get a 25 foot storm surge at some point.

In San Francisco (SF), where the waterfront has been a political battleground for decades, sea-level rise is too easy to ignore. 

While SF is less vulnerable to rising sea levels than other parts of the Bay Area, portions of areas bordering the bay would be at risk.

The challenge is to accommodate the bay’s impending expansion as it rises because of our warming planet. And to accomplish that in a way that won’t put our human and environmental resources at risk.  Read More

Will we keep our feet dry? Rivers are rising fast!

Since May 31th, it’s awfully raining in Germany, Belgium and the Netherlands. It looks like the monsoons we know from South East Asia. 

The next days, the water level in the rivers Rhine, Waal and IJssel, will reach maybe the highest level ever in summer times. A water level of more than 14 meters above sea level is not usual for this time of year. Read More

Fishermen predict flooding

Fishermen predict flooding

Hut’s research showed that data from temperature-sensing waders worn by the public and shared with scientists, can be used to decide where the most interesting places are to do more detailed and more expensive research.

A flooding costs billions.
Scientists can predict a flooding or droughts using sensors in a river or ditch. With the new sensing pair of waders, fishermen around the world, help scientists.

This new technology is a lot cheaper.

Porous concrete on roads means: less traffic noise and the end of splashing water and aquaplaning

In Europe we know this permeable or porous concrete saves may lives during the year. Why? Because the road stays dry, even with stormy weather. And we will face an increasing lot of storms the upcoming years.

A lot of countries don’t invest in permeable concrete. But maybe this system will change their minds.

Porous concrete on roads means: less traffic noise and the end of splashing water and aquaplaning

The average motorist appreciates the comfort of the porous coating. But there are also disadvantages:

  • higher costs for construction
  • less skid resistance of the road surface immediately after installation
  • reconcilable problems in combating snow and ice

From 1950 to 1980 the number of people living in favelas in Rio de Janeiro alone increased from about 170,000 to more than 600,000, and by the early 21st century it was estimated that there were as many as 1,000 favelas there.

Given the rate of change, our world will be a very different place by 2040. More and more people are moving to cities.

How will billions of city-dwellers access what they need without putting intolerable strains on the planet?

How can we plan now for more sustainable ways of life in a radically different world?

The underground water buffer creates a robust freshwater supply, without expensive reversed osmosis

Climate change must take into Northern parts of the world with wetter winters and drier summers. That means less fresh water in the period when farmers there are most in need.
