The Complete Beginner’s Guide to Greywater Systems
"There’s a reason that a key component of green building is water efficiency and reuse. Nationwide water use statistics are nothing short of staggering. According to the U.S. Environmental Protection Agency (EPA), the average American uses 82 gallons of water per day. Nationwide, landscape irrigation and other outdoor uses account for nearly one-third of all residential water use, average, totaling nearly 8 billion gallons per day. And some experts estimate that as much as 50 percent of water used for irrigation is wasted due to evaporation, wind, or runoff caused by inefficient irrigation methods and systems. That means billions of gallons of clean, fresh water is wasted daily, due to ineffective irrigation systems.
You may be thinking, 'there’s got to be a better way. How can I reduce my home’s outdoor water use?' You’re in luck — there’s a very simple, easy, and inexpensive way to do so. Greywater systems redirect greywater (water used for washing) from going into the sewer system and into an irrigation system instead. For any eco-friendly home, recycling usable water is definitely something to seriously consider. Installing a greywater system means you’ll conserve water and reduce your monthly utility bills, all while providing valuable nutrients to your landscape and garden.

What is greywater?
Greywater is the name given to water that’s already been used for washing purposes, like laundry, handwashing, showering, and bathing (NOT water that’s been in contact with feces, like from the toilet or washing diapers). Greywater systems, then, are used to redirect and recycle this 'once-used' water for other purposes. Greywater may look unclean (it does have the characteristic 'grey' tint, after all), but it’s perfectly suitable for watering the garden, irrigating your trees, and more.
Is greywater safe for plants?
For the purposes greywater typically serves, like irrigating landscaping, ornamental gardens, or trees, greywater is safe (if you use the right cleaners and body care products) — and can even be beneficial. Greywater contains traces of dirt, food, grease, and hair, which become pollutants when released into bodies of water. But to plants, these things are nutrients and valuable fertilizers. This makes greywater an even better option for watering and irrigation than regular water!
(Note: If you want to use greywater for your vegetable garden, just be sure it doesn’t touch any edible parts of the plant.)"

How To Build A #DIY #Greywater System (Complete Guide)
January 9, 2022 by Dylan Crosbie
"Welcome to our complete guide to building your DIY greywater system!
A greywater system will decrease your carbon footprint, save water and decrease your utility bills. The system recycles water from your home and allows you to use it again for irrigation and flushing toilets.
It can be a simple, low-tech system that will be cost-effective in the long run and lower your water usage by up to 40%."

We are testing out our new #lowtech washing machine 🤪
So far seems to be doing quite a good job with additional bonus: I'm actually happy for the weekend lancha and jetskies bonanza - more wake, better washing 🤣

Sieht (noch) nicht danach aus.
Aber es gibt einen Bot: @lowtechbot, @marieverdeil vom #LowTechMagazin-Team ist hier (https://solar.lowtechmagazine.com/de/about/team/) (Who else 👀 ? ) und das französische Low-Tech Journal ist im Fediverse:
@lowtechjournal
Hello fediverse!
I'm looking for any info or suggestion regarding tools or technologies in low tech and or low bandwidth situations in education.
I'm gathering hints, documentation, tips and anything that can be useful to allow people in areas with low internet connections and maybe old hardware to be able to get involved in teaching environment.
Please, if you can, share this so that I can get help from as many people as possible!
:boost_ok: Jeudi prochain à 18h30 au Rize à Villeurbanne, on parle Low-Tech avec la Myne, venez les rencontrer et échanger sur le sujet autour d'un bol de chips !

Where do the #lowtech and #NeoLuddites hang out? The #permaculture and #bicycle geeks? The co-op and #RepairCafe heroes?
Looking for alternate scenes around alternate living: sharing, building, eating, and learning together.
Much obliged.
Bonnnnjouuur ! Les premiers épisodes de notre #Podcast sont en ligne ! Vous vous demandez "C'est quoi la #lowtech" ?
