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."

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.'

#Cistern #WaterSystems: How They Work and Why They’re Useful

By Robert Maxwell
Updated on Sep. 26, 2025

"Has your interest in alternative water systems made you ask, what is a cistern? Read on to learn about this ancient way to store and supply water.

The basic idea of a cistern water system, which collects and stores water in or near a home, goes back centuries. In some parts of #WesternAsia, archeologists discovered lime plaster cisterns in the floors of houses that were at least 5,000 years old. Ancient #Romans also used cisterns beneath their houses to catch, filter and store #rainwater.

A cistern is a closed tank, somewhat like a septic tank, but the similarities end there. Instead of sewage, it collects rainwater for household use or irrigation. A home with a well might have a large tank to store water to prevent the well pump from having to work all the time. In some cases, you could consider that tank a cistern, but according to longtime plumber Danny Pen, most cisterns are buried."

Best Stands for #RainBarrels to Maximize #WaterHarvesting

Post published:February 13, 2026

"Raising a rain barrel off the ground improves access to the spigot, enhances drainage, and protects the barrel from damp ground. This guide highlights reliable stands designed for 45, 50, and 55-gallon barrels, focusing on durability, load capacity, and weather resistance. The selections below draw from top-rated options that balance robustness with practical design, helping you choose a stand that fits your weather, terrain, and watering needs."

How to Set Up a #RainwaterCollection System & 8 #DIY Ideas

Written by Author Lindsay Sheehan Published on March 26, 2021

"This technology can be traced back some 12,000 years in human history, and it makes just as much sense today to take advantage of a precious resource that freely falls from above.

The simplest #RainwaterHarvesting system involves a basic #RainBarrel situated next to your home.

[...]

Gutters made from coated aluminum and vinyl are the best choice for rainwater collection. Galvanized steel gutters are suitable for non-potable systems.

Avoid using gutters made with copper or lead materials."

So, before I start posting about #RainwaterCollection and #RainwaterHarvesting, I wanted to point out that while collecting rainwater is legal in most countries (though there can be local restrictions/regulations), there are some states in the #UnitedStates that restrict or prohibit #Rainwater collection.

Can You Go To Jail for Collecting Rainwater?

It's fine in most states, but some have stricter rules!

"While most states permit rainwater harvesting and some even encourage it, other states have specific rules and regulations around the topic. These states specify the uses of the water. For example, if the water can be collected for “non-potable” purposes, it means the water is not suitable for drinking but can be used for other things. Potable means it’s safe for drinking, cooking and bathing.

Here are a few with specific rules governing rainwater harvesting.

- #Alaska (rainwater okay, but groundwater is regulated)
- #Arkansas (legal with some regulation)
- #California (legal unless using it for landscaping)
- #Colorado (limited to 110 gallons per day)
- #Illinois (legal with some regulation)
- #Kansas (#WaterRights required, except for domestic use)
- #Louisiana (#cisterns must have covers)
- #Nevada (used to be illegal, but is legal with some restrictions
- #NorthCarolina (regulated)
- #Ohio (regulated for drinking)
- #Oregon (no longer illegal)
- #Texas (regulated)
- #Utah (rules about amounts)
- #WashingtonState (strict rules)

Taking a break to water the plants using #rainwater. Keeping one's #RainBarrel clean is essential to having good rainwater! And I've found that if mosquitoes are an issue, a light layer of olive oil (I save old, rancid olive oil for this purpose) can smother mosquito larvae. Natural dish soap does the same thing, without causing harm to plants.

Now, this article mentions using goldfish in one's rainbarrel. Ummmm... But, vegetable oils and natural soap will work (and so would #BTDunks )!

#ClimateChangeGardening: 12 strategies for a #resilient #garden

by Niki Jabbour

"#ClimateChange gardening is a set of tactics that make our yards and gardens more resilient to extreme weather as well as reduce our personal impacts on the climate. There are several ways to approach climate change gardening. You can use sustainable and organic gardening practices that put soil, #biodiversity, and #pollinators first. You can also plan to reduce plastic waste, up-cycle materials, and collect #rainwater.

3 reasons to care about climate change gardening

"Climate change gardening influences the health and success of your garden. When you nurture your soil, foster biodiversity, and support pollinators you create a garden that is more resilient to the challenges of climate change. Here are 3 reasons to care about climate change gardening.

- Extreme weather – The impact of weather related challenges like droughts, storms, precipitation, flooding, and above or below normal temperatures can be reduced with climate change gardening strategies.
- Pollinators, birds, and beneficial insects – Climate change can affect pollinators and birds in various ways. Weather extremes can impact migration timing and success, host plant growth and bloom time, disease and pest issues, and habitat and food supply.
- Non-native invasive pests and plants – With a longer growing season, invasive plants, pests, and diseases will move north and potentially affect plant health and crop yields."
