One year after Hurricane Ida, NYC updates its water infrastructure in the hopes of preventing another tragedy

2022-09-02T14:50:00-04:00

New York City is beefing up the effort to prevent a similar tragedy to Hurricane Ida a year removed from the historic storm’s wake of destruction, which left 13 residents dead and hundreds of others permanently displaced.

Mayor Eric Adams was on hand yesterday to showcase newly-installed stormwater infrastructure in the heavily-affected neighborhood of Ozone Park, Queens, in unison with Governor Kathy Hochul and the state’s Department of Environmental Protection. The city is investing some $2.5 billion there in the form of sewer upgrades which will be joined by a similar $454 million initiative targeting historically-flood-prone areas in Brooklyn, Staten Island, and other parts of Central and Southeastern Queens.

That money will all go towards replacing the antiquated, century-old existing system that, combined with the abundance of illegal basement dwellings in the neighborhood, created an untenable situation in September 2021, unable to handle the seven inches of rain that fell i...

New York Times' latest Op-Doc takes a dive into the sewage systems of Mexico City

2019-01-07T16:17:00-05:00

The New York Times' latest Op-Doc—part of their series of short, interactive, and virtual reality documentaries—profiles Julio César Cú Cámara, whose job it is to dive into the sewers and water treatment plants of Mexico City. For the past 36 years, Cámara has been a sewage diver, maintaining the sewage system's pipes and pumps, clearing them of blockages and reducing the risk of floods. Directed by Mexican filmmaker Esteban Arrangoiz, the film shows, as Arrangoiz writes, "how through his work, a human being is capable of finding beauty, pleasure and the essence of his humanity inside the detritus." Check out the film below.

This Nano Membrane Toilet could solve the world's sanitation crisis – and charge our phones

2016-01-05T14:44:00-05:00

Researchers at Cranfield University in the UK have created a prototype of a toilet that works without being connected to water or sewage systems, and that can generate electricity and clean water as it composts waste. [...] The Nano Membrane Toilet, which has been developed with funding from the Bill and Melinda Gates Foundation, would be a kind of ‘super-toilet’, helping to improve sanitation for people without access to utilities – at present some 2.5 billion people around the world.

This is how the Nano Membrane Toilet works: "The toilet flush uses a unique rotating mechanism to transport the mixture into the toilet without demanding water whilst simultaneously blocking odour and the user’s view of the waste. Solids separation (faeces) is principally accomplished through sedimentation. Loosely bound water (mostly from urine) is separated using low glass transition temperature hollow-fibre membranes. The unique nanostructured membrane wall facilitates water transport in the vapour state rather than as a liquid state which yields high rejection of pathogens and some odorous volatile compounds. A novel nano-coated bead enables water vapour recovery through encouraging the formation of water droplets at the nanobead surface. Once the droplets form a critical size, the water drains into a collection vessel for reuse at the household level in washing or irrigation applications. Following release of unbound water, the residual solids (around 20-25% solids) are transpo...

Waikiki Beach closed after heavy rains cause sewage spills

2015-08-25T14:31:00-04:00

Waikiki Beach closed on Monday after heavy rains caused by a tropical storm set off the spills. Tropical Storm Kilo caused 500,00 gallons of wastewater to come gushing out of manholes, making the waterfront unsafe for beachgoers. "Now's not the time to go swimming," said Lori Kahikina, Honolulu's director of environmental services. The beachfront sees about 4.5m tourists annually. It will be a few days before the ocean is safe for people to swim in again, Ms Kahikina said...

Duke researchers design toilet that turns waste into drinking water

2013-07-26T20:20:00-04:00

It works like this: people empty their latrines into a sewage receptacle (currently, latrines are often emptied into rivers), the waste gets funneled through a series of tubes and is pressurized at extreme temperatures, and the byproduct is clean, possibly drinkable water. Deshusses describes the process as “a pressure cooker on steroids.”

150 stories - but no sewer connection

2012-12-30T11:09:00-05:00

'[R]emember that a place like Dubai really emerged in the last 50 years. It was a sleepy, you know, Bedouin town half a century ago. And what you do is when you bring in the world’s, you know, most sophisticated architects and engineers, you can literally build anything, including a building of 140 or 150 stories. But designing a municipal network of sewage treatment is in some ways more complex. - KATE ASCHER

Terry Gross recently interviewed Kate Ascher about her skyscraper book, and ended up discussing the common lack of sewage connections in Dubai - including the Burj Khalifa. So they end up using trucks to cart the sewage to the central treatment plant, where they often end up queuing for 24-hours or more before they can be emptied.

Gizmodo calculated:

'The Burj Khalifa has 163 habitable floors. It's designed to hold 35,000 people at any given time. Now, humans produce 100 to 250 grams (3 to 8 ounces) of feces per day. Let's say 200 in this case, since these people are well fed. That's 7,000,000 grams per day. Seven tonnes of poop per day. Now, add human-produced liquids (pee, bathing, cleaning their teeth...) and the water to push the poop down its miles of sewage pipes. I think a very conservative total would be 15 tonnes of sewage per day.

That's a lot of poop.'
