Paris has a watery dream of swimming in the Seine – but can the planners take the plunge?

It all started on a hot summer’s day in August 2015, when hordes of people defied a 1923 law and plunged into a canal in the northeast of Paris. It was such a welcomed event that, in November, the City Hall officially proposed a plan for three swimming pools to be built along the south side of the Quai de la Loire canal basin, ready for this summer.

Paris Mayor Anne Hidalgo celebrated the plan on Twitter, writing: “City swimming: promise kept! Three pools on the Bassin de la Villette starting next July 15.” It is a bold plan that, ahem, hopefully will swim and not sink.


The Bassin de la Villette is located in the north east of Paris and is the widest part of the long and fascinating canal system that flows down into the Seine. It was inaugurated in 1808 by Napoleon Bonaparte to supply water to Parisians – they can't just drink wine you know – and was a former port area during the industrialisation of rivers. Now, it's a central cultural and recreational spot, boasting a theatre barge, boat rental, breweries and cinemas, and is a prime spot for summer wine drinking.

The temporary structures will be built into the actual Bassin, which connects the Canal de l'Ourcq with the Canal Saint-Martin. The smallest, a children's pool, will be just 40cm deep, a second will be up to 120cm deep and a third will be reserved for serious swimmers at 2m deep. The pools in total would stretch 90m end to end, and would take up 16m in width.

Liberté, Egalité, Water Qualité

Naturally, the water itself is a worry. The canal has fallen pray to a few rat infestations and, on occasion, you can watch giant rats being dredged up as you sip a fresh rosé on a canalside terrasse – but don't be put off just yet. Jean-Francois Martins, tasked with sports at the City Hall, offered reassurance to prospective Parisian bathers in Le Figaro newspaper, saying: "We've been monitoring the quality of the water in the Bassin de la Villette since 2009."

The canals were emptied and dredged under a year ago, uncovering bizarre objects hidden in their depths - from bottles to scooters to a stray toilet. Despite the occasional cupboard or vermin spotting, the canal is actually relatively clean and a calm hub in the bustling city, where people picnic, fish and commandeer model boats during the summer months. It is not uncommon to see overly zealous Erasmus parties dive into the canal on hot weekend evenings and there have been no reports of swimmers haemorrhaging from the mouth, eyes and internal organs after contracting Weil's disease (Google if you dare) just yet. So that’s something.

Managing the water for swimming will require stemming sewer overflow during heavy storms, illegal discharge into the water from quayside boats and barges, and agricultural run-off from farms upstream. It is doable but still a massive undertaking by the city and region of Île-de-France.

Will Paris ne regrette rien?

Is it all worth it? Perhaps. Many Parisians seem to have a thirst for outdoor swimming and will seek a cooling spot to escape the city heat again this summer – the City Hall estimates that around 1,000 people would show up to the pools on any given summer day next year. As a local and keen outdoor swimmer, a guarantee of good water quality would certainly draw me for a daily swim.

The pools will be a kind of summer pop-up, along with the annual Paris Plage which transforms the banks of the basin and Seine quayside into an urban beach every summer. This means that they will be taken down for the winter season as it is pretty unlikely that many people will want to float down a freezing canal.

Fanatics keen for a outdoor swim in the chillier months can head to the outdoor pool at Butte aux Caille in the 13th arrondissement, which is open year-round and now heated from the warmth given off by a data centre installed in the same building.

As part of Paris' Olympic bid for 2024, the city has also been overhauling the 38 existing swimming facilities; building innovative heating systems as part of a plan to make all the pools eco-responsible by 2024.

Another new, unusual, environmentally friendly pool-heating system can be found at the Aspirant-Dunand pool in the 14th arrondissement. Water from the Paris sewers is being used to warm this pool – which has cut its electricity bill by 50 per cent. A new heat pump system was installed at the pool following tests of similar systems at the pool and several others in the Paris region. The city has 2,400km of sewers under its streets and assistant mayor Célia Blauel said that the water they contained was between 13 and 20C all year round. This heat was taken from the water and used to heat the pool and showers.

In-seine urban planning

Not willing to stop at just a canal, the ambitious City Hall has also announced that they aim to make the river Seine clean enough to swim in by 2024. The city has even suggested staging Olympic events such as the swimming triathlon in the river.

So, will it work? Proposals to clean up waterways are a regular occurrence in many major European cities. Berlin’s 2014 scheme included a plan to swim in a part of the river Spree, but pollution from storm water run-off and coal mining put that one on the back burners. Over in London, there is the more viable Thamesbath project. It is a partially heated twin pool rather than an open swimming area but would use river water, filtered and cleaned through tanks and aquatic plant beds. It’s reached almost £150,000 on Kickstarter but is likely to cost a fortune, so don’t hold your breath. (Sorry).

But the idea of safe and clean urban swimming for the masses does float, as there are success stories already. Both Copenhagen and Zürich have cleaned up their open waters – a harbour and a lake – making it perfectly safe to jump right in.

Paris doesn’t have many ecological factors in its favour but the city of light has a big watery dream. In spite of the odds, this project may be just about achievable, and we could one day see tourists slip in for a dip in the Seine after a visit to the Eiffel tower.

Don’t forget your swimsuit.

Pembrokeshire's innovative new eco-hamlet is great. But it should be the size of a city

The opening in January 2017 of an “eco-hamlet” for council house tenants in West Wales is great news. I have nothing but praise for a development which builds houses with a low carbon footprint, using locally grown wood, to make homes which are well insulated and powered by solar energy. It was also quick to build, with large sections being made in a factory and then assembled on site. And it was relatively cheap – at around £70,000 to £100,000 per building, it is certainly comparable to the costs of more conventional builds.

These houses are an inspiration to the construction industry and an aspiration for the home owner. After all, who wouldn’t like to live in a house that had yearly utility bills of £200, rather than the national average of £1,500?

So the problem is not the six wonderful solar houses at Glanrhyd, Pembrokeshire, or the lucky people who will get to live in them (and enjoy shared use of an electric car). The problem is that we’ve seen all of this before – but nothing changes. What we really need is far, far more of them.

I’ve been involved in sustainable construction for nearly 25 years and seen many inspirational developments like Glanrhyd. There’s Julian Marsh’s home in Nottingham, Susan Roaf’s Oxford Ecohouse and the Hockerton Housing Project, to name but a few. The list is long.


Yet while many individuals continue to build these innovative and inspirational structures, we have a construction industry which still responds to these buildings with disdain. One executive from a large well-known house building company told me recently: “This is a new, expensive and untested technology. We just can’t risk building something so new with all the risks to the consumer and at a higher cost.”

But the situation is even worse than the disdain from the mainstream construction industry. Rather than being welcomed, the latest versions of these sustainable buildings are challenged at every turn. The initial response to the Welsh eco-hamlet plans were concerns about the materials, the technology and the design. The houses at Glanrhyd then had more than 20 planning conditions placed upon them. The CEO of Western Solar, the company behing the hamlet, freely admits that nearly half of their research budget went on solving problems they encountered along the way.

Thinking and building big

So it seems this kind of development just isn’t celebrated enough. There is a general atmosphere of mistrust from construction professionals. It is seen as too complex, too expensive, too risky. Yet there are positive reactions, too. Welsh politician Lesley Griffiths had this to say about the new houses in Glanrhyd:

This scheme ticks so many boxes. We need more houses, we need more energy efficiency, we want to help people with fuel poverty. It’s been really good to hear how they have sourced local products. It’s great they’re using local people to build the houses.

Surely we need to take the eco-technology we have and start rolling it out on a much larger scale. To do so would be a massive step in meeting the significant housing shortage (an estimated 125,000 extra new houses are needed every year). It would also address the disrepair of our current housing stock, and help refit the millions of houses in good repair but requiring improved performance in order to achieve the government’s 2050 carbon reduction target.

We must not forget that the 2050 Climate Change target is not some arbitrary political policy, but one based on the environmental challenge facing all of us. We need to play our part in slowing down the speed of climate change and adapting to the changing natural, social and economic environment.

The solar houses in Pembrokeshire are wonderful. But until we start building huge numbers of buildings with similar credentials, we are just celebrating a cottage industry rather than restructuring our urban environment for an uncertain future.The Conversation
