Why Preventing Backflow Is Important

Image
Back in 1973, the U.S. Environmental Protection Agency enacted the “Safe Drinking Water Act” to safeguard public water systems from being contaminated by unwanted particles or pollutants due to cross-connections or backflow. This is a significant concern for farms and lawns using irrigation systems. Image source: mesaaz.gov Overseeing backflow has become so crucial that even an official organization, American Backflow Prevention Association (ABPA), was established to make sure that backflows are prevented. The association with more than one thousand members defines backflow as “the undesirable reversal of flow of non-potable water (irrigation water or other treated water) through a cross-connection and into the piping of a public water system or consumer’s potable (drinking) water system.” Backflow can have two causes: backpressure backflow and backsiphonage. Backpressure backflow occurs when downstream pressure, particularly from the irrigation system, becomes greate...

What Exactly Is The Role Of Irrigation In Agriculture?

Irrigation is of value especially for communities that could be facing the effects of drought.  It is defined as the artificial application of water to soil, in the appropriate amounts and frequency, to cause optimal soil infiltration and plant growth.  The conditions to take into consideration are soil type, vegetation, size of the area to be irrigated, water pressure, and local circumstances.  Image source: clwa.org The increase in agricultural production and productivity is highly dependent on the availability of water.  Insufficient, inconsistent, and uncertain rain is causing unpredictability in agriculture.  In some parts of the world, rain is restricted to only a few months in a year, and there are times when these rains don’t come as expected, causing areas of the country to experience drought.  Irrigation assists in effectively controlling drought and famine.  In irrigated lands, a higher rate of productivity is experienced as c...
