Urbanization, population growth, industrialization and water-requiring energy production are creating a huge competition and demand for good quality and potable water resources. Depending on the final quality of reclaimed water, its use in urban irrigation will likely require use of modified sprinklers or drippers to minimize direct contact with the foliage of plants, to reduce salt scorching. Furthermore, the use of alternative irrigation water sources like rainwater, stormwater, reclaimed, A/C condensates and residential graywater, all of the sudden become potentially viable sources to lessen our urban irrigation dependence on limited … The sources of water for irrigation can include surface water sources, groundwater sources, municipal water supplies, grey-water sources, and other agricultural and industrial process wastewaters. The best source of water is whatever happens to be closest to you. Sparta, MI 49345. Drip irrigation focuses the water onto the plant itself. The Best Sources of Water for Irrigation.

Just use “plant friendly” soaps (those low in salts, and free of boron and bleach), and you have a good source of irrigation water that’s already paid for.

Appropriate alternative water sources and the reutilization of agricultural effluents can reduce the impact of rice production and animal husbandry on the natural water bodies. Here are some points to consider. You can be assured our editors closely monitor every feedback sent and will take appropriate actions. Public health safety concerns often significantly limit or restrict the use of reclaimed water to irrigate edible plants/ crops. But some comes from nonrenewable groundwater sources. Its irrigation viability is more likely for sites with a relatively large air-conditioned indoor footprint vs. irrigation area footprint (i.e., commercial buildings and their associated landscapes), offering the possibility of supplying significant volumes of water. Wada et al. No matter how clean the water may look after filtration, collected rainwater is not a potable water source. On its way to the rain barrel, water can pick up gravel from your roof, leaves from the gutters, or other detritus.

Along with soils, water and its management through irrigation have been the foundation of these urban agricultural activities. In a few special cases, it is possible to irrigate cropland using a municipal water-supply system. Thank you for taking your time to send in your valued opinion to Science X editors. The most common sources of water for irrigation include rivers, reservoirs and lakes, and groundwater. At the residential level, graywater reuse could thus represent a substantial irrigation water source (saving potable water supplies) if coupled with some minimal treatment and a suitable low-pressure irrigation system (i.e., drip or even flood by gravity) for turfgrass and cultivated beds with ornamentals or edible garden plants. For more information, see the Rainwater Availability Map. Depending on how they are collected and stored, these water sources potentially could have the best chemical quality (Table 1) compared to a conventional “ideal” irrigation source, particularly rooftop-collected rainwater.
