Topic: Rainwater Harvesting


A Hero in Vienna

Excerpt: AGRAWAL looked at how utilities work in the United States and the concept of passage rights, which allows for utility groups to have access to properties to provide services. He came up with something similar, acquiring rainwater harvesting rights.

“I want to rent your rooftop. I will pay you 1,000 rupees, about $15 to $20. People thought this was free money. But then, they thought, ‘If he takes all the rainwater, there’s nothing left for us.’”

So, he proposed that they share the cost and the water. “Half the rainwater is mine, half is yours.”

He funnels his share from each household reservoir to a village reservoir, which serves the rest of the people who are not able to collect rainwater.

Excerpt: He went to a local government office and he asked them if they wanted to provide water for their people. Officials there said,”’We are poor people. We don’t have anything to contribute.’ I said, that’s not true. By accepting that you are poor, someone told you that you are poor and you accepted it. In that process you lost your dignity. So don’t ever call yourself poor.” They offered 10,000 square meters of land at no cost for a whole year’s worth of water.

10 Cool Rainwater Collection Systems

Excerpt: Setting up a rain water collection system at your home is a great way to conserve precious drinking water, as well as store additional water for gardens, pets and to have on hand in case of emergencies.

Excerpt: At a bare minimum, you should install a reverse osmosis system at each sink where the rainwater will be plumbed. If you plan on using your collected water only for showers or laundry, purifying is not necessary. Just add a safe algaecide to your collection barrels regularly.

UA students hands-on rainwater harvesting practice

Excerpt: Students at the UA are getting their hands dirty in an effort to conserve the most precious resource in the desert: water.

Excerpt: For a class project, Cox’s water harvesting class is evaluating several sites on campus to install a water system.

Excerpt: Water harvesting can also be done at home and is not too expensive a process, according to Joe Silins, who works for the Watershed Management Group and hosts water harvesting workshops in Tucson.

“These are simple and affordable techniques that we focus on that pretty much anyone can get into,” Silins said. “I think it’s great that students get the opportunity to improve their campus in a hands-on capacity, letting them leave a mark beyond their tenure at the university.”

A Better Rainwater-Harvesting System

Excerpt: Harvesting rainwater to use for growing vegetables makes a great deal of sense. Unfortunately, the most common method of rainwater harvesting isn’t the most effective. Typically, gardeners invest in a rain barrel — which holds only 50 or 60 gallons of water — and then dole out the captured water to plants as needed, hopefully emptying the barrel before the next storm.

Excerpt: To store as much rainfall as possible in your garden soil, you can set up a rainwater irrigation system that diverts your roof runoff water directly onto your garden beds (or lawn, if you prefer).

Excerpt: Each time it rains, roof water will flow into the trash can and out through the manifold to wherever you’ve directed the hoses. Check the system during a heavy downpour to confirm that the hoses are distributing the water where you want it. You may need to add more holes or possibly tape some holes closed.
