Tap water is usually used to water
plants because of its accessibility, whereas distilled water is avoided because
of its known harmful effects on plant growth. The effects of greywater has
caused many people to have different beliefs on its use. In this project, the
effects of greywater compared to distilled water and tap water will be tested.
Greywater is a type of wastewater
produced at home from anywhere except for in toilets, urinals, and any drains with
garbage disposals. The wastewater, or greywater, systems are modifications of
septic system technology. (Septic system technology uses a combination of
nature and proven technology to treat wastewater from household plumbing
produced by kitchen drains and laundry, and bathrooms, and it usually consists
of a septic tank and a drain field). This means that greywater is useful as
irrigation and is available for reuse (Anderson, 2003).
The use of distilled water over
natural resources of water such as rain and river water introduced a group of
problems. The lack of nutrients and actively injurious qualities in the water unsecured
what was regarded as normal plant behavior, and often natural waters were
resorted to secure the plants. Plants, after being in distilled water for
varying time periods, have been proven to not be completely recoverable because
the water strips the plants from its nutrients and makes it impossible to
retain the lost nutrients, or the lack of nutrients per se (True, 1914).
is a factor in the growth of healthy plants. The major nutrients contained in
the most popular fertilizers are nitrogen, phosphorus, and potassium. A deficiency
in nitrogen in plants can induce yellowing of leaves and stunt growth, whereas
too much nitrogen can delay the fruiting process. Phosphorus plays an important
role in the overall health and growth of the plant (seed germination, protein
formation, fruit and flower formation, metabolism, and photosynthesis).
