Optimizing the #Rainwater #Harvesting and #Roof Sprinkling System to Adapt to #Urban #ExtremeHeat

"Roof watering is a novel strategy for reducing air conditioning energy consumption and mitigating excess urban heat, yet its application is often constrained by water availability. To address this challenge, we propose an adaptation strategy that integrates rainwater harvesting tank with roof sprinkling to strengthen urban heat resilience."

[1/2] #StarIsland, #GosportNH - #GreenGosport Initiatives that can be practiced on the #Mainland!

Green Practices

"For centuries, living on Star Island has required a knowledge of conservation and respecting the environment. Since 2011, we have taken a more proactive approach to this with the Green Gosport Initiative — a program designed to educate our island and mainland communities about sustainability, and to serve as a model for others. The efforts we make on island are sometimes huge (we recently installed a solar array), but often are relatively easy to accomplish. Here are some of the things we do on Star to reduce our impact locally while thinking globally. We’ve included suggestions about how you can take what we do on the island and practice it on the mainland.

#Reuse

Star Island: Everything carried to the island needs to be carried off, unless it can be turned into something useful. Therefore, we seriously consider how we can reuse items on-island before trashing or recycling them. For example, several years ago we collected used glass bottles to line the beds in our vegetable gardens. We also reuse historic furniture and replace small parts instead of replacing entire fixtures. We also reuse food waste to create compost, which in turn helps to grow more food.

Mainland: Instead of throwing something away, ask yourself if you can reuse it. Some simple things to reuse include plastic sandwich bags for more sandwiches, shopping bags as trash bags, and newspaper for kindling or wrapping paper. Random bits of plastic from everyday products and toys might also be great sources for a rainy day art project. And to help you stay hyrdated, use a water bottle to refill instead of buying new bottled water.

#Recycle

Star Island: When you can’t reuse, recycle. We send metal, glass and paper off island to get recycled if we can’t reuse it.

Mainland: Most municipalities have curbside recycling, and we encourage you to take advantage of this easy way to recycle. Also, if you’re ever out and about and need to dispose of something (paper coffee cup, plastic drink bottle), check to see if it is recyclable and find a proper receptacle instead of trashing by default.

Use #RenewableEnergy

Star Island: In the fall of 2014 we installed a solar array on Star that has provided an estimated 60% of our energy needs since the 2015 summer. We’re not fully running on solar power, but this renewable energy source is our focus moving forward.

Mainland: Installing solar panels on your home allows you to take advantage of sustainable energy and excess, unused energy can even be back fed into the larger electrical grid. Not only are you taking a step to reduce carbon emissions, but you could also be saving money.

Turn Off Lights

Star Island: We turn the lights off whenever possible. Although lights are left on in certain public spaces such as walkways, hallways, and the main lobby for safety, for the most part the island goes dark at night. We even rely entirely on candlelight for evening chapel services. On Star we’re swapping outdated bulbs (incandescents) for more efficient LEDs, and considering sensors for lights in areas that don’t need to be lit when no one’s using them at night (bathrooms, hallways, walkways). Fewer lights means less electricity, reducing the need to use as much diesel to support the solar array.

Mainland: If you’re the last one leaving a room, turn the light off; installing automatic switches can be helpful if you’re apt to forget. Also, question if you really need the light on-daylight is often just fine. Fewer lights means less electricity, which may even reduce your electric bill.

Use Energy Efficient Equipment

Star Island: Replacing equipment with more efficient models has allowed us to reduce demands on our island’s infrastructure. A recent example is the purchase of a new dishwasher, which uses less power during operation and also uses less water. Less water used means less drinking water treated and less used water sent to the island’s wastewater treatment facility. This leaves more water available for other uses, such as guest showers. Water and wastewater treatment are also two of the three biggest electrical uses on-island, so this energy and water efficient dishwasher means an overall reduction in energy use. On Star we’re also swapping outdated bulbs (incandescents) for more efficient LED’s.

Mainland: Replace household appliances with those receiving Energy Star rating. Energy Star products are “certified to save energy without sacrificing features or functionality.” This rating helps you choose household equipment that can help realize energy savings. Click here to learn more.

#GrowYourVeggies

Star Island: Over the past few years we’ve been generating more produce from the several vegetable gardens on island. This produce supplements the food we order from the mainland. By growing our own food, we are also able to eat fresher, more nutritious food and also reduce the cost of our food bill.

Mainland: Just like a 1940’s victory garden, growing a portion of your own food is a great cause. You are stating that you want to know where your food comes from, and you’re choosing varieties of produce you like. Having your own food in your yard, or in a planter on your porch might also mean less trips to the grocery store.

Eat Your Veggies

Star Island: We know that eating your vegetables isn’t just good for your body, it can be good for the environment, too. Every meal on Star includes a vegetarian option. When you register, just let us know you’ll be choosing the vegetarian option. And while we have your attention, why not consider making your stay on Star a chance to try out being a vegatarian? You’ll still get your protein and iron, don’t worry. Want to learn more? Click here to read about the effects of cattle farming on the environment.

Mainland: Try practicing a vegetarian diet. You might find your grocery bill to be lower than usual, and you might find some awesome recipes that you’ll keep forever. If switching to a vegetarian diet is a bit too much, we suggest trying #MeatlessMondays as a way to incorporate meals one day a week that are less intenstive on the environment.

#Compost #FoodWaste

Star Island: Everything carried to the island needs to be carried off, unless it can be turned into something useful. We separate food waste from trash and compost this to transform it into a beneficial commodity that helps improve island soil in gardens and on the lawn. Chickens also help by eating leftovers such as bread, oatmeal, and mashed potatoes (they love vegetarian pot pie!). Composting food waste helps reduce demands on island boats and provides the island with a reusable product.

Mainland: A small compost bin is easy to use and maintain for household scraps. You can build your own, or check with your town/municipality to see if they participate in a program that offers compost bins for a reduced cost. By composting you reduce the amount of waste that is thrown into landfills. Some municipalities are even starting to collect compost along with trash and recycling. We encourage you to investigate your mainland options including companies that collect compost for you.

Take Fewer, Shorter Showers

Star Island: If you’ve stayed on Star Island you know that we have a shower schedule that provides 3 showers for both staff and guests over a 7-day period. We limit showers because water on-island is hard to come by. Yes, there’s plenty of salt water nearby, but fresh water isn’t readily available (recall the Rime of the Ancient Mariner: Water, water everywhere and not one drop to drink). Fresh water is provided through reverse osmosis of sea water, filtration and disinfection of collected #rainwater, and water delivery by boat (i.e. a lot of work).

Mainland: An every other day shower schedule isn’t just something to practice for water conservation, it’s also recommended for your skin and hair health."

#Rainwater Harvesting for Drylands and Beyond by Brad Lancaster

https://www.harvestingrainwater.com/

Okay my 330 Gallon IBC's arrived and after they are installed in their spots, I will have just over 3000 gallons of rain catchment. the 4 330 gallons will compliment the existing 14 65 gallon and 4x275 gallon IBC's

The 65 gallons are daisy chained and catch from the roof, then are pumped to fill the 275's (and soon 330) gallon IBC that live away from the house. Normally 1-2 storms will fill the existing system so hopefully we will fill stuff up quick, then I pull the diverters and save it for summer. The water is used for fruit trees and gets me about ⅓ of the way through the summer. this will extend things quite a bit

I would add more but I do not want to stack the IBC's as full they weigh a lot

🌱💧🌵 Water Harvester: An Invitation to Abundance (27 min, 2022)

Tucson resident Brad Lancaster believes that cities around the world can live off rainwater. This is the story of how he transformed his neighborhood by experimenting with water harvesting, worked with the city to legalize those methods, and empowered others by proving that abundance rooted in sustainability is possible.

Research - #RainBarrels and Other Household Stormwater Strategies Are Working — For Now.

May 5, 2026

Excerpt: " 'When we talk about #CircularEconomy, most people think about #recycling waste and materials. But the concept of circular economy also applies to water. Here we're talking about installing #rainwater #cisterns, reusing water from the sink to flush toilets and using water-efficient appliances. While those may seem like small steps at the individual level, we found that if they are widely adopted, they can have a significant collective impact,' said Fernanda Cruz Rios, PhD, an assistant professor in the College of Engineering, who was a co-author of the research. 'They help reduce demand on the municipal supply, and the energy needed to treat and distribute that water. But what we found was that these strategies offer a real double benefit. In areas like #PhiladelphiaPA and #CamdenME, that are particularly vulnerable due to their proximity to large bodies of water, we were able to see a meaningful reduction in flooding volumes when circular water strategies were adopted.'

"Despite the ongoing compliance efforts, the cities of Philadelphia and Camden have around 16 billion gallons of combined #sewer overflow, according to reports from their respective water utilities.

"Over the last two and a half decades, Camden has established a stormwater management plan, including decentralized strategies, an upgrade to #stormwater infrastructure and storm water management modeling. To understand the overall impact of these efforts, in hopes of applying findings to other vulnerable urban areas, the Drexel team created a computer model of stormwater movement using data from Cramer Hill, a neighborhood of Camden in the state’s 'coastal hazard zone' that is highly susceptible to tidal and storm-surge flooding.

"The researchers structured the model so that it could quantify the distinct effects of outdoor strategies (cisterns and rain barrels) and indoor strategies — efficient fixtures and reusing sink wash water (#greywater) for toilet flushing. It simulated and measured the effect of 16 different combinations of strategies, ranging from rain barrels of different sizes, to varying levels of adoption of water-efficient fixtures and greywater reuse.

"Each scenario was simulated using precipitation and tidal data from 2014 as a baseline and flooding measurements projected at locations across the neighborhood and at five stormwater outfall areas that contribute to combined sewer overflow discharges into the #DelawareRiver.

The results show that the combination of retrofitting homes with #WaterEfficientFixtures as well as installing rain barrels and practicing greywater reuse, when adopted by 75% of households, could reduce the volume of combined sewer overflows by as much as 11% and the volume of #floodwaters by up to 13%.

" 'This finding is an important and encouraging piece of information for municipalities that are facing similar challenges,' Marques said. 'Although broad adoption of these measures can be challenging to achieve, confirmation of its effectiveness may help to make the case.' "

We survived Day 1 of the #HeatDome. Temps were in the low-90's and very humid. Living room was down to 77 with the portable A/C running for a couple of hours (mostly for the doggo, though we enjoyed it). The exhaust tube was getting a bit too hot for my comfort level, so now it's back to the fans. Tomorrow is supposed to be 100 F. I just watered both gardens -- nothing is wilting... yet. Used only collected #rainwater for watering. And bonus -- I salvaged a #Turmeric plant that was growing in a #Compost pile!

My solar powered water pump has finally stopped working, the silicone tubing in the peristaltic pump has degraded and started to leak.

Considering this version has been outside since 2023 and has been pumping unfiltered rain water I think it's done pretty well.

The good news is that if I replace the silicone tubing Ill be able to rebuild it and get it working again. I might simplify the control circuitry as it got a bit complicated.

Then it can get back to helping me avoid carrying water up from the bottom to the top as it's a 2.5M climb and I'm a little lazy.

The #depaving groups reclaiming #UrbanGreenSpace

by Jennifer Cole, Mar 21, 2026

"It took two years, but finally, in 2025, Jean Norwood’s dream of turning the parking lot at #MorningstarMissionary Baptist Church in #PortlandOR, into a play area for children and a #FoodGarden with #FruitTrees came true. Working with Norwood to bring her vision to reality was #DepavePortland. Since 2008, the Portland-based nonprofit has been digging up paved surfaces, freeing the trapped soil underneath and #regreening the newly reclaimed space.

"There are an estimated 2 billion parking places in the United States, an area comparable in size to the entire state of Vermont. That figure does not include #sidewalks, schoolyards or other paved surfaces, which, along with #CarParks, trap heat, intensifying the urban #HeatIsland effect in some cases by up to 10 degrees Fahrenheit compared with surrounding areas. '#Asphalt makes your space hotter in the summertime, and colder in the wintertime,' Norwood says.

"When asphalt is removed and the soil beneath is exposed, those dynamics begin to reverse. The ground can absorb and store #carbon, and #rainwater is able to filter into the soil rather than running off into sewers. #Trees and #gardens can be planted that provide shade and a #habitat is created for #birds, #insects and other #wildlife.

"This was Norwood’s dream for the parking lot at Morningstar. Going from concrete to fruit trees, though, takes patience. 'First,' she says, 'there was about six months of planning and submitting requests for permitting.'

"Depave guided Norwood and the church through all of it, even seeking out grants to help cover costs. When it came time to depave the parking lot, volunteers recruited by Depave used crowbars, shovels, bare hands and wheelbarrows to lift out the pavement and daylight the soil beneath. Depave also worked with Morningstar on finding contractors to build the play area and raised #GardenBeds, and on choosing the plants for each newly #regreened space. It’s a process Depave has perfected at more than 82 sites across Portland."

100-Year-Old Way to Filter #Rainwater in a Barrel

by Linda Holliday
February 25, 2015

"During our boiling, broiling, blistering summer of 2012 here in the Missouri Ozarks, water was a topic of conversation wherever we went. Creeks and ponds dried up (some never recovered) and the water table dropped, forcing a few neighbors to have their well pumps lowered or to even have deeper wells drilled.

"Many folks shared memories of rain barrels, cisterns, hand pumps and drawing water with a well bucket as a child, usually on grandpa and grandma’s farm. Some said they’d never want to rely again on those old-time methods of getting water. But, at least they knew how it was done.

"It seems we have lost much practical knowledge in the last 50 or so years because we thought we’d never need it again. Now we are scrambling to relearn those simple know-hows.

"A tattered, 4-inch thick, 1909 book I happily secured for $8 in a thrift store reveals, among umpteen-thousand other every-day skills, how to make homemade water filters. The instructions in 'Household Discoveries and Mrs. Curtis’s Cookbook' are quite basic as everyone had a rain barrel back then and presumably knew how to clean the water. Now, 104 years later, I am thankful the authors had the foresight to preserve their knowledge for us, and pointed out that rainwater collected in barrels from a roof is a necessity in some locations, but also is best for laundry and 'often more wholesome for drinking purposes than hard water.'

Scientists Are Warning of A Brand-New Kind of #AcidRain

Story by Darren Orf

Key points:
- While acid rain caused by sulfur dioxide is an environmental threat of the past (at least, for now), a new kind of acid is proliferating in rain water—as well as groundwater, ice cores, and even human blood.
- #TrifluoroaceticAcid (#TFA) is a subclass of “#ForeverChemical” that’s been steadily increasing in concentrations around the world.
- With calls to consider this rise in TFA a planetary threat, some governments are starting ban chemicals linked to TFA—but the threat will require global cooperation.

"Acid rain may have a sequel, and like most sequels, it’s arguably worse.

"While the world’s first bout of acid rain (at least, in modern times) came from increased concentrations of sulfuric acid produced largely from coal plants, this new #anthropogenic source is possibly more pervasive, more persistent, and more sinister. Its name is Trifluoroacetic acid (TFA), a kind of 'forever chemical' that, for decades, has been steadily increasing in #RainWater—but not just rain water.

"Countries around the world have found increasing concentrations in #groundwater, #ArcticIceCores, #wine, and even #HumanBlood. In fact, TFA is likely the most pervasive form of per- and poly-fluoroalkyl (#PFAS)—technically, a subclass known as ultrashort-chain perfluoroalkyl acid (#PFAA)—on Earth due in part to the fact that longer-chain PFAS degrade into TFA via #incinerators or #SewageTreatment plants. They’re also used in #refrigerants instead of #chlorofluorocarbons and #hydrochlorofluorocarbons, which were famously known to deplete the Earth’s #OzoneLayer.

"In October of 2024, a team of European environmental scientists raised the TFA alarm, stating that a rise in concentration could be considered a threat to '#PlanetaryBoundaries' — a system designed to make sure the planet remains #habitable for human life (which we are doing a real bang-up job at following).

" 'Since the 1990s, it has been suggested that hazard-related concerns of TFA and other short-chain PFAAs are much lower than those of PFAAs with longer perfluoroalkyl chains, which are more #bioaccumulative and generally more #toxic,' the authors wrote back in October. 'However, these early reports did not consider TFA’s ubiquitous accumulation in the environment, in particular its observed accumulation in water resources and #bioaccumulation in various plants, including crops.'

"One of the most dangerous things about PFAAs is what we don’t know about them. Unlike other PFAS (of which there are, sadly, thousands of different kinds), TFA is so small (a.k.a. ultrashort) that it’s water-soluble, meaning it likely passes through the human body pretty quickly. A new Nature article reports that some scientists find this evidence compelling enough to not even consider TFA a kind of PFAS, but a growing chorus of voices are raising concerns that increased concentrations of TFA in water and food sources could render TFA’s fast-moving nature a moot point.

"In fact, TFA’s water-solubility could be a long-term headache. If scientists and governments eventually decide that TFA does need to be removed from drinking water and other sources, current filtration technologies are not up to the task. In other words, ridding the world of TFA will not only be immensely difficult, it’ll also be incredibly expensive. Current regulations to eliminate certain forms of PFAS are already proving to be fiscally onerous.

"Thankfully, some governments are taking action. #Denmark, for example, banned 23 substances earlier this month known to contain PFAS that contribute to rising TFA concentrations. Meanwhile, the #US is lagging behind—the Environmental Protection Agency [#EPA] doesn’t even define TFA as a 'forever chemical,' much to the dismay of #environmentalist groups and to the merriment of many #industry leaders.

"Rising concentrations of TFA is the acid rain sequel no one wanted. But just like every terrible sequel ever made, it seems like we’re getting it anyway."

‘#ForeverChemicals’ – the part of cleaning you don’t want to last

"Notable categories of cleaners that either may contain, or have historically contained, PFAS are:

- glass and hard surface cleaners
- fabric, upholstery, and #CarpetCleaners and treatments
- #waxes and polishes for #floors, #furniture, #cars and #boat vessels
- dishwashing rinse aids
- #AerosolPropellant-based #cleaners and #AirFresheners
- #paints and #coatings.

"Floor sealers and finishes – products that cure into a film once applied – often contain PFAS. During floor stripping and waxing, PFAS concentrations in dust and air particulate matter were one order of magnitude greater than typical residential indoor air and two orders of magnitude greater than outdoor air, according to a 2022 study.

"But now the cleaning products #Industry wants to keep consumers in the dark about the use of these chemicals in their brands. Earlier this month, a bill was introduced in Congress on behalf of leading household cleaning product makers that would deny Americans the right to know about #ToxicChemicals in cleaning products.

"The manufacturer #Reckitt applauded Rep. Larry Bucshon (R-Ind.) for introducing the bill, which would rob consumers of crucial information about the ingredients in their products. Reckitt makes popular household brands like #Lysol, #Woolite, #AirWick, #Vanish, #Calgon, among many others.

And industry giant #SCJohnson
called for a 'clear federal standard' on disclosing ingredients, knowing any such standard could take a decade or longer. The company manufactures #Glade, #Drano, #Pledge, #ScrubbingBubbles, #Shout and #Windex, along with many other products, including #Ziploc."
