How is Rainwater Harvesting done ? Harvesting System Broadly rainwater can be harvested for two purposes Storing rainwater for ready use in containers above or below ground Charged into the soil for withdrawal later (groundwater recharging) From where to harvest rain Rainwater harvesting can be harvested from the following surfaces Rooftops: If buildings with impervious roofs are already in place, the catchment area is effectively available free of charge and they provide a supply at the point of consumption.
Paved and unpaved areas i.e., landscapes, open fields, parks, stormwater drains, roads and pavements and other open areas can be effectively used to harvest the runoff. The main advantage in using ground as collecting surface is that water can be collected from a larger area. This is particularly advantageous in areas of low rainfall. Waterbodies: The potential of lakes, tanks and ponds to store rainwater is immense.
Stormwater drains: Most of the residential colonies have proper network of stormwater drains. Ersson rainwater harvest and purification (original) Background In January 1996 we installed a rainwater catchment system to capture Oregon's abundant rainfall.
Portland receives between 3 and 4 feet of rainfall annually. Harvest Rain DVD. Harvest Rain - The Movie review by Doug Pushard In harvesting rainwater, the overwhelming majority of the attention is focused on active rainwater collection systems - that is systems with tanks and pumps. Passive rainwater catchment is too often overlooked, and yet, a very impactful and important practice. Passive rainwater collection is the art of slowing down rainwater and letting it infiltrate locally rather than channeling it too quickly running off the land. It promotes healing of the land and treats rainwater as an asset rather than a problem.
It has been practiced for centuries; however, with the advent of deep wells and cheap electricity to drive big pumps, it has all but been forgotten. However, with droughts, significantly larger storm events and the new emphasis on building green; it maybe getting a second life. Collect Rain Water For Your Garden 3in1 System. Interview_Sally. Harvesting Rain Downunder by Doug Pushard Rainwater harvesting is not just a topic of interest in the arid southwest, or even just parts of the United States; it is a topic of worldwide interest.
Sally Dominguez, CEO of Rainwaterhog from Sydney, Australia, was recently in the United States promoting her Rainwaterhog product line; an innovative, attractive interconnectable line of rainwater tanks that can be used vertically or horizontally. Sally, how long ago did you get involved in Rainwater Harvesting? I guess I started about 15 years ago when I started designing houses with large steel tanks. I have also lived in houses with rainwater systems; one was where a possum drowned in the drinking water tank, so I also seen the drawbacks first hand. What is the weather like in Sydney?

After all, water is plentiful here, right? While is it true that we get a lot of rainfall, up to 60 inches per year in some places, the summer months can be very dry. Climate change has made our winters here warmer and there is less snow in the mountains to fill our reserviors during the summer. Watershed collection for our growing urban population can offset critically needed water from rivers during the fall salmon spawning season. Recent summers have been dry enough for the local government to call for voluntary and sometimes mandatory water use restrictions. My rain barrel design.
Functionality update: 21 June 2007 We spent a week visiting the grandkids.
While we were away, the National Weather Service reported over an inch of rain in the area. The first barrel is full and there are no leaks. Now to add more barrels... Functionality update: 28 July 2007 I added the second barrel to this downspout using a 3/4" male pipe thread to hose adapter near the bottom of each barrel. The connection between barrels is made with a washing machine hose (yet another leftover, about $6 if you buy new) because it has the needed female hose fittings on each end.

How to Plan a Home Rain Water Collection System. Capture System. The Capture System by Doug Pushard You have decided to invest in a rainwater harvesting system, but where do you start?
Residential_gutters. Residential Gutter Sizing by Doug Pushard Gutter sizing is an aspect of rainwater collection that has been studied extensively and can be calculated based on published guidelines in the plumbing codes. For example, the Uniform Plumbing Code (UPC) recommends that a gutter system be able to carry the runoff of the heaviest 60 minute downpour recorded in the last 100 years. The International Plumbing Code (IPC) has a similar, but not exact, published sizing recommendation. Both plumbing code manuals include the necessary sizing calculations to properly size a gutter system. Raingutters. Making Raingutters Work! Why gutter protection should be standard on every home.

Rainwater Catchment Systems May be Better than the Big Pipe! By Doug Pushard In a recent research project by Brad Crowley, home-based cisterns were compared against the $1.4 billion “Big Pipe” program to upgrade the current Portland, OR combined storm water and sewer system. At stake is a way to reduce the estimated 2.8 billion gallons of raw sewage and stormwater that is dumped annually into the Willamette river. The study discovered that harvesting rainwater onsite may be a more cost-effective and environmentally sensitive approach to the public works projects.
The purpose of the master thesis by Brad Crowley was to perform a neighborhood–based rainwater catchment analysis using the city of Portland as an example, with emphasis on analyzing the impact if all single family residences used rainwater for key indoor functions rather than municipal water. Besides eliminating the need for a massive project, other benefits of the smaller scale project included:
