#direct potable reuse
Note
Hello! I saw your post about wastewater treatment and thought you might like to read about what my city did during a major drought about a decade ago. To this day I still don't understand it, but it was apparently a big deal in treatment circles?
https://www.tpomag.com/editorial/2016/12/how_wichita_falls_turned_a_drought_into_enlightenment
Hey! I'm real behind on my inbox but this is real cool! Here's the link you shared.
Hmmm, let me see if I can explain what's happening here.
So one important thing to know is that drinking water, in very broad terms, comes from one of two places: 1) an aquifer (some kind of underground water source. might be a cave but is probably a crack in a rock or a sandy/gravely layer under the surface), or 2) a surface water body (lake, river, reservoir). In very general terms, surface water needs extra treatment. Most aquifers (though not the kind that are just caves) get their water after it's filtered through the dirt and rock above it, which filters out a lot of contaminants. This means that it can start out a lot cleaner. (Though not if the rocks it filters through are salty or high in arsenic--aquifers are preferred, but if they're not being used there's usually a good reason.)
Surface water, on the other hand, has shit in it. Literally. The fish shit in it. The birds flying overhead shit in it. Dirt washes into it. People dump stuff into it. Hopefully they have a permit for that, sometimes they don't. Algae grows in it. So surface water drinking water treatment plants usually need to have much more intense treatment than groundwater (aquifer) drinking water because there's more *stuff* to filter out.
So when the drought happened in the early 2010s, the lakes that were being used for drinking water got low. Enter secondary wastewater.
Secondary wastewater is wastewater that has already been through a first treatment stage. I believe--and someone can correct me on this if I'm wrong--that first stage is typically letting the water sit so that the majority of the solids (*cough*) can filter out. Secondary wastewater may or may not be clean enough to release, depending on various factors, but it is much cleaner than what came in.
So what they've done here is take that partially treated wastewater and run it to the drinking water plant. Very serendipitously, the drinking water plant already had microfiltration and reverse osmosis filtration set up for incoming water, because they'd previously used a brackish (salty) water source that needed the extra filtration. Both of those forms of filtration also happen to be the gold standard for filtering wastewater for drinking water. The only thing that could've made it better would be if they'd had UV treatment too. They then took this now doubly-pretreated water and mixed it with untreated lake water. Which meant that the water went through the whole regular lake water treatment process as well. And since lake water is surface water, we know that was extra thorough too. It also says in the article that they were monitoring the whole process extra carefully to make sure no wastewater contaminants were making it through. And no one got sick!
Not every water treatment plant will be lucky enough to have both extra filtration in place and access to secondary wastewater that's clean enough to use this way, but it's still extra cool that that was the case here! A lot of people are grossed out by direct potable reuse of wastewater (which is industry-speak for pumping watewater directly to your drinking water plant to treat and use). But honestly, I don't think it's any grosser than drinking treated surface water. In some ways, secondary wastewater is actually better, because you at least know basically what happened to it, while surface water has just been wandering free in nature, getting up to who knows what...
Thanks for the ask!

"Namibia is the driest country in Sub-Saharan Africa, and home to two of the world’s most ancient deserts, the Kalahari and the Namib. The capital, Windhoek, is sandwiched between them, 400 miles away from the nearest perennial river and more than 300 miles away from the coast. Water is in short supply.
It’s hard to imagine life thriving in Windhoek, yet 477,000 people call it home, and 99 per cent of them have access to drinking water thanks to technology pioneered 55 years ago on the outskirts of the city. Now, some of the world’s biggest cities are embracing this technology as they adapt to the harshest impacts of climate change. But Namibia leads the way.
How did this come about? In the 1950s, Windhoek’s natural resources struggled to cope with a rapidly growing population, and severe water shortages gripped the city. But disaster forced innovation, and in 1968 the Goreangab Water Reclamation Plant in Windhoek became the first place in the world to produce drinking water directly from sewage, a process known as direct potable reuse (DPR).
That may sound revolting, but it’s completely safe. Dr Lucas van Vuuren, who was among those who pioneered Windhoek’s reclamation system, once said that “water should not be judged by its history, but by its quality”. And DPR ensures quality.
This is done using a continuous multi-barrier treatment devised in Windhoek during eight years of pilot studies in the 1960s. This process – which has been upgraded four times since 1968 – eliminates pollutants and safeguards against pathogens by harnessing bacteria to digest the human waste and remove it from the water. This partly mimics what happens when water is recycled in nature, but Windhoek does it all in under 24 hours...
Pictured: These ultrafiltration membranes help to remove bacteria, viruses and pathogens. Image: Margaret Courtney-Clarke
“We know that we have antibiotics in the water, preservatives from cosmetics, anti-corrosion prevention chemicals from the dishwasher,” Honer explains. “We find them and we remove them.”
Honer adds that online instruments monitor the water continuously, and staff ensure that only drinking water that meets World Health Organisation (WHO) guidelines is sent to homes. If any inconsistencies are detected, the plant goes into recycle mode and distribution is halted until correct values are restored.
“The most important rule is, and was, and always will be ‘safety first’,” says Honer. The facility has never been linked to an outbreak of waterborne disease, and now produces up to 5.5m gallons of drinking water every day – up to 35 per cent of the city’s consumption.
Namibians couldn’t survive without it, and as water shortages grip the planet, Windhoek’s insights and experience are more important than ever.
Interest from superpowers across the globe
In recent years, delegations from the US, France, Germany, India, Australia, Singapore, and the United Arab Emirates have visited Windhoek seeking solutions to water shortages in their own countries.
Megadrought conditions have gripped the US since 2001, and the Colorado River – which provides 40 million people with drinking water – has been running at just 50 per cent of its traditional flow. As a result, several states including Texas, California, Arizona and Colorado are beginning to embrace DPR.
Troy Walker is a water reuse practice leader at Hazen and Sawyer, an environmental engineering firm helping Arizona to develop its DPR regulations. He visited Windhoek last year. “It was about being able to see the success of their system, and then looking at some of the technical details and how that might look in a US facility or an Australian facility,” he said. “[Windhoek] has helped drive a lot of discussion in industry. [Innovation] doesn’t all have to come out of California or Texas.”
Pictured: The internal pipes and workings of Namibia's DPR plant. As water becomes scarcer in some parts, countries are looking to DPR for solutions. Image: Margaret Courtney-Clarke
Namibia has also helped overcome the biggest obstacle to DPR – public acceptance. Disgust is a powerful emotion, and sensationalist ‘toilet to tap’ headlines have dismantled support for water reuse projects in the past. Unfortunately, DPR’s biggest strength is also its biggest weakness, as the speed at which water can re-enter the system makes it especially vulnerable to prejudice, causing regulators to hesitate. “Technology has never been the reason why these projects don’t get built – it’s always public or political opposition,” says Patsy Tennyson, vice president of Katz and Associates, an American firm that specialises in public outreach and communications.
That’s why just a handful of facilities worldwide are currently doing DPR, with Windhoek standing alongside smaller schemes in the Philippines, South Africa and a hybrid facility in Big Spring, Texas. But that’s all changing. Drought and increased water scarcity worldwide are forcing us to change the way we think about water.
Now, the US is ready to take the plunge, and in 2025, El Paso Water will begin operating the first ‘direct to distribution’ DPR facility in North America, turning up to 10m gallons of wasterwater per day into purified drinking water – twice as much as Windhoek. San Diego, Los Angeles, California, as well as Phoenix, Arizona are also exploring the technology."
Of course, DPR is not a silver bullet in the fight against climate change. It cannot create water out of thin air, and it will not facilitate endless growth. But it does help cities become more climate resilient by reducing their reliance on natural sources, such as the Colorado River.
As other nations follow in Namibia’s footsteps, Windhoek may no longer take the lead after almost six decades in front.
“But Windhoek was the first,” Honer reminds me. “No one can take that away.”"

Hello! Engineering related question if you don't mind me asking:
I was doing some research on grey-water recycling, and am not sure why it isn't the standard in the majority of the world. It seems to reduce water usage by a reasonable amount (maybe 20%) without having significant downsides (maybe a small upfront cost?)
Despite this, it isn't very common. Why?
I don't mind, I love engineering questions!
The prime reasons are: cost and regulations.
Grey water recycling still takes tanks, pumps, and other filtration systems that require tending. While it's not particularly more expensive than a septic system up front, its still an extra cost that most clients don't want to pay for, plus long term maintenance costs (too which the client sees only these, not the reduced water bill, its just how most people see things: big number upfront bad). Plus, at least for American housing, the house would need special plumbing for grey water collection and use, which would cost you more from the architect or from a plumbing company for retrofitting an existing residence.
Second is regulation. I know some states and countries are changing this, but grey water still has limited usage. For Arizona, USA, it can only be used for gardening and up to a certain amount (400 gallons per day) (https://www.azdeq.gov/graywater) and worse again, only on non-food plants that aren't trees or bushes. Arizona is currently working on changing regulations for Direct Potable Reuse (taking wastewater and treating it enough to reuse as potable water) which would likely see some changes to the grey water reuse rules as well since our state is on the cusp of water scarcity.
Grey water reuse can be a huge help, and since it can be used for flushing toilets (one of the larger wastewater producers of the house), gardening, and some other minor uses, it tends to be a good reduction to water use. The biggest hurdles are regulations and cost, since unless regulations lighten, there isn't anywhere to go, and most clients want the cheapest upfront cost, not the cheapest long term cost. The best way forward would be for regulations to lighten AND for the government to offer rebates like they do for solar panels. That'd incentivize it financially and make it more legal, thus more would do it.

Untreated wastewater can contain a variety of pollutants, including nutrients, heavy metals, and organic compounds, which can degrade water quality and harm aquatic ecosystems. Wastewater treatment removes these pollutants, reducing the risk of environmental pollution and supporting the health and integrity of ecosystems. Clean water discharged from treatment plants helps maintain biodiversity, support fisheries, and preserve natural habitats.
4. Promoting Resource Recovery
Wastewater treatment plants are increasingly adopting resource recovery technologies to extract valuable resources from wastewater streams. These resources may include energy, nutrients, and biosolids, which can be reused or repurposed in various applications. For example, biogas generated from anaerobic digestion of wastewater sludge can be used to generate electricity or heat, while nutrient-rich biosolids can be used as fertilizer in agriculture.
5. Fostering Economic Development
Investments in wastewater treatment infrastructure and technology contribute to economic development by creating jobs, stimulating innovation, and attracting investment. Sustainable wastewater management practices can enhance the resilience of communities to environmental challenges and promote long-term economic growth and prosperity.
Challenges and Future Directions
While wastewater treatment plays a vital role in sustainable development, it faces challenges such as aging infrastructure, emerging contaminants, and climate change impacts. Addressing these challenges requires investment in infrastructure upgrades, adoption of innovative technologies, and implementation of integrated water management approaches. Additionally, raising awareness about the importance of wastewater treatment and promoting water conservation practices are essential steps in ensuring the long-term sustainability of water resources.
Conclusion
Wastewater treatment is a cornerstone of sustainable development, providing essential services for protecting public health, preserving water resources, and mitigating environmental pollution. By transforming contaminated water into a valuable resource, wastewater treatment contributes to the resilience and well-being of communities and ecosystems worldwide.

California regulators approved new rules last month to enable water suppliers to treat wastewater and redistribute it as drinking water. The state says that the new standards, which took years to craft, are the most advanced in the nation for treating wastewater and will add millions of gallons of additional drinking water to state supplies. But hurdles, including stigmas that surround what’s known as “direct potable reuse,” persist. We talk about California’s new approach to wastewater recyclin

Promote sustainable living with greywater treatment!!!
In the pursuit of sustainable living and responsible water management, Ecovie stands as a pioneer, advocating for and implementing innovative solutions such as greywater recycling, greywater treatment, and rainwater harvesting. The importance of these practices extends beyond individual households to contribute significantly to water conservation efforts, environmental stewardship, and the creation of resilient communities.
Greywater recycling, a cornerstone of Ecovie's initiatives, involves the collection and treatment of gently used water from sources like showers, sinks, and laundry machines. Instead of allowing this water to flow down the drain, greywater systems capture and filter it for reuse in irrigation and toilet flushing. The significance lies in mitigating the strain on freshwater resources by repurposing water that is still suitable for non-potable purposes. The commitment to greywater recycling aligns with the ethos of sustainable living, where every drop of water is treated as a valuable resource rather than a disposable commodity.
Greywater treatment, another vital component of mission, elevates the practice of recycling by ensuring that reclaimed water meets high-quality standards. Through advanced treatment technologies, company addresses concerns related to contaminants and pathogens, making the recycled greywater safe for use in various applications. This dual focus on recycling and treatment not only conserves water but also enhances the overall efficiency and safety of the process, establishing a model for responsible water reuse.
Rainwater harvesting complements greywater recycling by tapping into an additional source of untapped water – rain. This practice involves capturing rainwater from roofs and surfaces, directing it through a filtration system, and storing it for later use. The importance of rainwater harvesting lies in its ability to reduce reliance on traditional water sources, especially during periods of drought or water scarcity. It empowers individuals, businesses, and communities to harness the power of nature, turning rainfall into a sustainable water supply for landscaping, flushing toilets, and other non-potable uses.
Ecovie's integrated approach to water sustainability underscores the interconnectedness of these practices, forming a holistic water management solution that benefits both individual users and the environment at large. By promoting the adoption of greywater recycling, it contributes to water conservation efforts, reduces the carbon footprint associated with water treatment and distribution, and fosters resilience in the face of changing climate conditions.
Beyond the immediate environmental impact, the importance of initiatives also extends to the financial and social realms. As communities face the challenges of water scarcity and rising utility costs, the adoption of sustainable water practices becomes a financially prudent and socially responsible choice. The solutions empower individuals and organizations to take control of their water usage, reducing dependence on centralized water infrastructure and fostering a sense of self-sufficiency. The dedication to greywater recycling exemplifies a commitment to a more sustainable and resilient future. By embracing these innovative water management practices, individuals and communities can contribute to a world where water is revered, reused, and respected as a finite resource. The initiatives not only reflect a progressive approach to water sustainability but also serve as a beacon, inspiring others to join the movement towards responsible and conscientious water stewardship.

To many of us, the behave of eliminating a toilet can be an afterthought — a short pause in our daily routines. But have you ever ended to ponder where this water moves, how it's treated, or the vital significance of that system to our environment and culture? The trip of toilet water is both interesting and important to our contemporary world.
The Pattern of Bathroom Water
From the moment you remove, toilet water embarks on a sophisticated journey. Initially, it trips by way of a network of pipes and sewers. With respect to the place, this wastewater may possibly combine with stormwater or stay separate. The good goal, however, is to obtain the water to a wastewater therapy facility.
Therapy and Change
At the therapy center, bathroom water experiences multiple stages of purification.
Primary Treatment: Big strong components are removed. That period generally involves settling and sedimentation processes.
Secondary Treatment: Biological processes break up natural materials. Helpful microorganisms enjoy an essential role in that period, eating a lot of the waste.
Tertiary Treatment: Advanced procedures eliminate remaining contaminants, including nitrogen, phosphorus, and actually some major metals. This point may contain purification, substance therapies, and more.
When handled, the water may be returned to local waterways, ensuring little environmental impact. トイレつまり水Qドットコム
The Environmental Relationship
Wrongly treated bathroom water can wreak damage on ecosystems. Nutrient overloads could cause algal plants, which minimize oxygen degrees in water and harm aquatic life. Pollutants can contaminate normal water sources and endanger equally human and pet health.
In some progressive towns, the journey doesn't stop following the tertiary treatment. Realizing the worth with this resource, they're recycling treated wastewater, sometimes actually for drinking purposes. This method, referred to as direct potable delete, requires extra refinement measures, including advanced filtration and disinfection.
The Potential of Toilet Water
Considering the international water situation, treating and reusing wastewater, including toilet water, is now more crucial. Areas with water scarcity issues, like parts of California or Singapore, already are leading in wastewater recycle, ensuring sustainable water assets for their populations.
More over, there's continuous study in to harnessing power from wastewater. The organic products in toilet water can be used to produce biogas, a renewable energy source.
In Conclusion
The next time you remove, remember that the water swirling down isn't only disappearing. It's embarking on a trip of purification, possibly sell, and represents a critical role in our environment and society. Even as we experience global problems like water scarcity and environment modify, understanding and appreciating our wastewater programs is more important than ever.

A Guide To Becoming A Self-Sufficient Home
Becoming a self-sufficient home is a commendable and empowering goal that involves reducing your dependence on external resources and becoming more self-reliant when it comes to your basic needs. While complete self-sufficiency may not be achievable for everyone, taking steps in this direction can lead to a more sustainable and resilient lifestyle. Here are some key aspects to consider when aiming to become a self-sufficient home.
Energy Independence
Start by replacing old appliances with energy-efficient models, upgrade insulation, seal air leaks, and switch to LED lighting to reduce energy consumption. Then, you will want to focus on switching your energy sources. You have several options:
· Solar Panels: Investing in solar panels from Now EV is one of the most effective ways to achieve energy independence. Solar panels harness the power of the sun to generate electricity for your home, reducing or even eliminating your reliance on the grid.
· Wind and Hydro Power: Depending on your location, wind turbines or hydroelectric generators may also be viable options for generating renewable energy. You often need a lot of land to do this. Most houses in urban locations couldn’t opt for this, but those in the country could.
Water Self-Sufficiency
There are several options when it comes to being more water self-sufficient. You can start collecting rainwater by installing rain barrels or a larger rainwater harvesting system to capture and store rainwater for irrigation, flushing toilets, and other non-potable uses. To reserve and reuse is one of the best ways to achieve self-sufficiency, so implement graywater systems to recycle water from showers, sinks, and washing machines for use in irrigation. This reduces the strain on freshwater resources.
If your property allows, drilling a well can also provide a reliable source of potable water.
Food Production
Again, this depends on how much land space you have, but you could have the potential to live off the food you produce in your own home. For example, you could raise chickens for eggs or goats for milk. These animals can provide a steady supply of food products. Smaller properties can still enjoy self-sufficiency in the way of food. Start by growing fruits, vegetables, and herbs in a garden or on your balcony. Gardening provides fresh and organic produce and reduces your reliance on store-bought food.
Waste Reduction and Recycling
Make an effort to compost kitchen scraps and yard waste to create nutrient-rich soil for your garden, and set up an efficient recycling system to minimize waste sent to landfills. If you can, also make conscious choices to reduce packaging waste by buying in bulk and using reusable containers.
Energy-Efficient and Sustainable Building
You may have to start from the very foundation to be as self-sufficient as possible. Design your home to utilize natural heating and cooling through passive solar design, proper insulation, and efficient windows and doors. When redesigning your home, use sustainable and eco-friendly building materials with a lower environmental impact. You could even consider off-grid options like composting toilets and off-grid heating systems.
Skills and Knowledge
Take some time to acquire essential skills such as gardening, food preservation, carpentry, and basic plumbing to maintain and improve your self-sufficient home. It can help you connect with like-minded individuals and local communities to share knowledge, resources, and support for your self-sufficiency journey.
Becoming a self-sufficient home is a journey that requires commitment, dedication, and continuous learning. It is not about complete isolation from the outside world but rather about reducing dependence on external resources and living more sustainably. Whether you aim to generate your energy, produce your food, or manage your water resources, each step towards self-sufficiency brings you closer to a more resilient and eco-friendly lifestyle.

Eco-Friendly Car Wash: Clean Your Ride while Saving the Planet
In today's world, sustainability and environmental consciousness are becoming increasingly important. Even in the seemingly simple task of washing your car, you can make a positive impact on the planet. In this blog post, we'll explore eco-friendly car wash practices that will not only keep your ride sparkling clean but also contribute to a greener, cleaner environment:
1. Waterless Car Wash Solutions:
Traditional car washes can use an excessive amount of water, contributing to water wastage and pollution. Consider using waterless car wash solutions that require little to no water, yet effectively clean your car's surface. These products contain lubricants and surfactants that encapsulate dirt particles, allowing them to be safely wiped away without scratching the paint.
2. Use Biodegradable Car Wash Soaps:
If you prefer a water-based car wash, choose biodegradable car wash soaps. These products are formulated to break down naturally without harming aquatic life or contaminating water sources.
3. Opt for Eco-Friendly Cleaning Tools:
Replace traditional sponges and wash mitts with eco-friendly alternatives. Microfiber wash mitts are not only effective at cleaning but also trap dirt and debris efficiently, reducing the need for excessive scrubbing.
4. Capture and Reuse Water:
If you decide to go with a traditional car wash using water, try to capture and reuse the runoff. Use a bucket or a rainwater harvesting system to collect the water, which can then be used for non-potable tasks like watering plants or cleaning other outdoor surfaces.
5. Choose Environmentally Conscious Car Wash Facilities:
If you prefer a professional car wash, look for facilities that prioritize eco-friendly practices. Some car wash businesses employ water recycling systems, use biodegradable products, and implement energy-efficient technologies.
6. Clean in the Shade:
Washing your car in direct sunlight can cause water and soap to evaporate quickly, leading to water waste and streaky surfaces. Choose a shaded area to clean your car, ensuring you use water more efficiently.
7. Avoid Hosing Down Driveways:
When rinsing your car, avoid hosing down driveways or sidewalks, as it can carry pollutants and chemicals into storm drains and waterways. Direct the runoff to permeable surfaces like lawns or gravel areas instead.
8. Skip Unnecessary Cleaning:
Don't wash your car excessively. Instead, clean it when it's visibly dirty or after driving on salt-covered roads during the winter months. Over-washing can strip away protective coatings and waste resources.
9. Eco-Friendly Interior Cleaning:
For interior cleaning, use eco-friendly products like plant-based cleaners and microfiber cloths. Avoid harsh chemicals that can release harmful fumes into the air.
10. Spread the Word:
Encourage your friends and family to adopt eco-friendly car wash practices. By raising awareness about the importance of sustainability, we can collectively contribute to a cleaner planet.
By embracing eco-friendly car wash practices, you can enjoy a spotless ride while doing your part in preserving the environment for future generations. Let's make every car wash a green initiative and drive towards a cleaner, greener future!

ADVOCACY ENVIRONMENT
Recycle, reduce, and reuse have been the mantra of environmentalists for many years, and it still holds true today. A more sustainable and biocentric worldview can still be promoted by tiny, everyday gestures, even though systemic change is required to change our current direction. Thought and deed taken together have the power to change things for the better.
1). RECYCLING-In 2018, the United States alone produced 292.4 million tons of solid garbage, or almost five pounds per person daily. Everything from food and technology to bottles, cartons, and furniture is included in this garbage. By recycling, giving, and using recovered energy, a significant portion of the trash can be diverted.
2). CONSERVING WATER-The typical American household uses 80 to 100 gallons of water per person each day. The UN estimates that the average person only requires 5.3 to 13.2 gallons of water each day. The most valuable resource we have is probably potable water because we cannot live without it. Reduce how frequently you shower, wash your car, do the laundry, wash the dishes, and engage in other water-intensive activities to reduce how much water you use. Alternately, you may switch to water-saving gadgets like a composting toilet.
3). CHOOSING ALTERNATIVES TO DRIVING-According to the EPA, the typical passenger car emits about 4.6 metric tons of carbon dioxide annually. Every day, more automobiles leave the assembly lines, and the total amount of pollutants produced by all the moving parts is concerning. Consider biking, walking, or taking public transportation to get to your location if driving isn't absolutely necessary for you.
4). SAVING ELECTRICITY-According to the EPA, the typical passenger car emits about 4.6 metric tons of carbon dioxide annually. Every day, more automobiles leave the assembly lines, and the total amount of pollutants produced by all the moving parts is concerning. Consider biking, walking, or taking public transportation to get to your location if driving isn't absolutely necessary for you.
5). BUYING USED-According to the World Economic Forum, the garment industry alone is responsible for 10% of global emissions, and 85% of textiles are disposed of in landfills annually. We could divert a sizable quantity of waste from landfills and use less energy in the manufacture of new goods if more people choose to purchase secondhand clothing, furniture, homes, and appliances.
6). USING REUSABLE CONTAINERS-According to the UN, 300 million tons of plastic garbage are produced annually by people. In addition to increasing emissions, the manufacture of plastic damages wildlife and contaminates rivers by ending up in the oceans and streams. Think about switching to Tupperware, paper straws, mason jars, beeswax wraps, reusable water bottles, biodegradable packaging, and other more environmentally friendly alternatives.
