Rainharvest Systems and Five Seasons Brewing teamed up to create a microbrew made from 100% on-site captured rainwater!

Until this year, there were three Western states where it was illegal to have a rain barrel in your back yard: Washington, Utah, and Colorado. A change to local laws means we can scratch the latter off the list!

So your garden’s all planted, and your rows are marked. Maybe you’ve got some upside-down tomatoes going, and your compost bin is chugging right along. You’ve probably got quite a few thirsty plants to take care of!

Rainwater collection is controversial in certain parts of the U.S.. If rainwater harvesting is allowed in your area, though, it’s a great way to water your garden without drawing from the municipal water supply!

Store bought rain barrels can run you upwards of $100. Instead of dropping a ton of cash at the garden center, though, you can make your very own! Some restaurants will even give you their used 55 gallon food grade containers for free, which are perfect for making a rain barrel. Ask around…you might just be surprised!

Here’s a great video from HGTV on how to build your own rain barrel, complete with a spigot:

We are seeing more climate conscious design in architecture: In this case; the rain screen.

A skin over the house is designed to manage and harvest occasional heavy precipitation, to provide protection from premature decay from moisture intrusion.

I like the way the rain-screen is carried up over the roof and mounted flush with the photovoltaic solar panels on the roof for a sleek look while also protecting the building.

Like a skin over the building; this Cumuru wood cladding is designed to shed rain water separately from the structure of the building. Rain screens deter rainwater intrusion into walls - by shedding most of the rain and by incorporating storage to reuse the rainwater - which you can see below the doors here.

There’s 8 other sustainable features, as well.

Rather than attacking the symptoms of moisture intrusion, rain screens tackle the source-the forces that drive water into the building shell. By neutralizing these forces, rain screens can withstand extreme environments. They appear to be effective in any climate and handle any weather condition short of a disaster.

All rain screens include the following elements:

• Vented or porous exterior cladding
• Air cavity (a few inches of depth is sufficient)
• Drainage layer on support wall
• Rigid, water-resistant, airtight, support wall

Integral gutters and downspouts are hidden behind the rain-screen. These then carry rainwater for storage in underground tanks.

The home also features passive solar heating through large expanses of south facing glass. These windows are protected from the summer sun with fixed sun louvers made of steel and Cumaru wood.

So as not to trap too much heat, low South-facing operable windows work in tandem with skylight vents in the north-facing roof-top pull hot air out of the top of the building for a thermal chimney effect.

For maximizing filtered daylighting, a three-level steel frame with milky glass inside encloses the staircase for spatial separation but spreading daylight between the rooms of the house.

The sustainable features are:

1. Enough rooftop photovoltaic solar panels for a net zero electricity supply (90-100%) for an average home.
2. One on-site 1.2 KW Windspire wind turbine that could produce about 20% of the energy an average home (550 kWh a month) assuming wind speed of at least 12 miles-per-hour year round.
3. Geothermal heat exchange between the house and the below-ground 55 degree temperatures year round, providing a constant starting point for both heating and cooling.
4. Epoxy coated gyp-crete floors for interior thermal mass to prolong passive heating and cooling
5. Passive solar design: low South-facing windows with sunlight access to thermal mass in the floor.
6. Heat-chimney effect created with roof ventilation in North skylights for expelling hot air
7. The framing wood was recycled from an ammunition plant.
8. Recycled materials in interior finishes such as the composite recycled paper countertops.

and of course

9. The rainwater reclamation using a wooden slat skin to keep water off the building and stored in underground tanks. Cumaru is one of the hardest woods on the planet and can be harvested sustainably.

But it comes from South America, so there is quite a carbon footprint getting it to Kansas City.

Rainwater harvesting makes a lot of sense: the initial investment can be quite low (especially if you do it yourself), and your plants love rain water.  Unfortunately, as Rachelle Carson Begley once noted, an awful lot of commercially-available rain barrels are, well, ugly.

A rain barrel or two may seem like the perfect solution for watering the garden without waste and without adding to your water bill. Before you build your rainwater harvesting system, though, you might want to make sure that it’s legal to do so. There are three states that say the water that falls from the sky belongs to them, not to just anyone.
