How Many Rainwater Guides Are Enough?

As a few of you know, one of my pet peeves is the overabundance of largely repetitive rainwater harvesting guidebooks. How many is enough? Do we really need to continue spending hard earned taxpayers monies (or even private monies, for that matter) on doing numerous manuals on rainwater catchment? Do we need one for every city in the US or every major city in the world? Do these really create value? >> more

Passive versus Active Rainwater Harvesting

There is wide spread interest in water conservation and specifically in capturing and rainwater harvesting in both residential and commercial buildings to reduce costs, reduce the environmental impact of the building and lessen the load on the municipal sewer and stormwater systems in the arid southwest where droughts are a way of life. Harvesting rainwater from rooftops is one solutions to conserving our precious water, where it can be used instead of municipal drinking water for many non-drinking water (i.e. non-potable) applications (e.g. landscape, toilet flushing) as well as drinking water. There are two general types of rainwater catchment systems - "active" or "passive". >> more

Rainwater Harvesting System Integrated into Home Design

This rainwater harvesting (RWH) system, with an above-ground, 7,500 gallon (usable) poured-concrete cistern, used for both potable and nonpotable purposes, was designed and constructed in 2001 as an integral part of a new single-family home in Key Largo, Florida. Rain is collected from a 1,700 square-foot white Galvalume roof and gathered in six-inch copper gutters with spash shields at roof valleys for occasional heavy downpours. Copper plumbing is used throughout the house as well. >> more

One Way To Conserve on the Ranch and Farm

Agriculture and ranching consume a substantial amount of potable and pumped water around the country, and to some extent in Northern New Mexico. In some areas of the US, farms and livestock consume up to 60% of overall water use. This water is usually either clean, highly processed potable water or well water pumped from precious underground aquifers. >> more

Rainwater Catchment System Pump Sizing

Pumps are an integral part of almost all rainwater catchment systems; however, sizing a pump correctly is not straightforward and installers often fail to make the appropriate calculations. Much has been written on pumps for irrigation systems and for wells, but rainwater harvesting pumps can be markedly different. This series of articles is aimed at shedding light on the differences and assisting in properly sizing rainwater pumps. This first article will explain pumps and general pumping concepts >> more

Potable Rainwater: Filtration and Purification

Rainwater harvesting is viewed by many, including the EPA, as a partial solution to the problems posed by water scarcity: droughts and desertification, erosion from runoff, over-reliance on depleted aquifers, and the costs of new irrigation, diversion, and water treatment facilities. Harvested rainwater in the U.S. is used mostly for irrigation; however, there is a growing interest in using rainwater for drinking and other indoor uses. >> more
