Rainwater Harvesting: Then and Now

Rainwater Harvesting: Then and NowI recently found this guest blog post on ValleyCrest Takes on Water Management.  The post was written by Mark Hopkins, a veteran leader in the landscape and irrigation industry.  Mark writes about the history of rainwater harvesting and shares some expertise and insight about residential and commercial rainwater collection today.

Here is an excerpt:

Rainwater harvesting can be traced back over 3000 years. In Jordan, King Mesha of Moab, commanded that all citizens dig cisterns for the collection of rainwater. Failing to comply with those water-saving guidelines probably resulted in more than a fine! In ancient Rome, atrium-fed rainwater collection cisterns were common place and were an important part of the region’s history. [Many of our grandparents had rainfall collection here in America in the 1800s and early 1900s.]

Due to rising costs and water shortages, there is a new buzz towards the age-old practice of rainwater harvesting. In a recent report by the Natural Resources Defense Council eight cities were studied for the potential economic impact of water harvesting. It is estimated the residents of these cities could save over 90 million dollars each year by adopting simple rain collection techniques. The study also finds that rainwater harvesting is not just applicable in residential settings; it can also be used on a commercial basis. Businesses can harvest rainfall from rooftops and parking surfaces with the potential of satisfying 21% to 75% of their annual water needs.

Many states are also getting into the act by providing resources for those individuals and businesses interested in water harvesting. For example, The Texas Water Development Board has created a Rainwater Harvesting Manual which outlines many methods of collection, formulas to estimate system sizing, available rebates and a wealth of other information.

When it comes to water harvesting, the need is now, resources are readily available and cost-saving benefits are measurable. Rainwater harvesting has evolved. [Even with a small amount of storage, those who choose to do the “right thing” can supplement their municipal water usage by an extraordinary 60, 70% and more.]

Rainwater Harvesting Education for Developing Countries

Rainwater Harvesting Education for Developing CountriesRainBank Rainwater Catchment System’s president Ken Blair is a co founder and former director of Bank on Rain, a non profit organization providing solutions to developing countries for clean drinking water. Over the past few years, Ken has enjoyed traveling to Sierra Leone Africa, along with others, to assist in providing clean drinking water and sanitation education to school children.

While stepping down from the Bank on Rain board, Ken plans to expand his philanthropic efforts with education offerings to organizations seeking to promote rainwater collection. As such, Ken plans to teach nonprofits and other groups how to introduce rainwater collection in developing countries.

By expanding his reach and working with many to achieve his goals, Ken states. “I feel my talents can be used on a broader spectrum by working with many organizations rather than just one. The need for clean drinking water is a world-wide issue and there are many groups that do good work – all of which need support from contributors and volunteers.”

What is the best storage tank for my rainwater catchment system?

Rainwater from your roof needs to be stored for future use and there are many types and manufacturers of water storage tanks. Above ground plastic tanks are a economical way to store rainwater. Most potable plastic water tanks are made from Polyethylene and it is recommended that they be “tumble molted”.

What is the Best Storage Tank for my Rainwater Catchment System2Sizes vary from a simple 50 gallon rain barrel all the way up to 10,000 gallons. All should have a UV protection warranty for at least 8 years. Dark colors are recommended to alleviate light penetration which can cause algae growth. Multiple tanks can be manifolded together to achieve the volume of storage needed. Keep in mind that plumbing should be under ground for frost protection.

There are vertical cylinder plastic water tanks if you have a large area for storage. Slim line design plastic water tanks are best suited for urban settings where space is an issue. There are box type plastic water tanks for storage under decks.

All rainwater storage tanks should be NSF approved for drinking water, should you decide to go potable now or in the future. There is a tank that will fit every application.

In the next installment of this series, we will discuss steel tanks with poly liners.
