Canna banana cattails vetiver phragmitis are some of the quick growing plants which can be used for bio filtering of waste waters. Each of these plants or several based on water to be purified are to be grown in buckets filled with sand. Each bucket has a tap at the bottom to allow the treated water to flow into the next bucket. Feeding of waste water is from top while withdrawal is at the bottom. Each bucket has a perforated tube embedded to allow air to be introduced into the interiors of the bucket. When the waste water enters the first bucket the tap is kept closed so that the roots of the plant are inundated with this waste water. Once the bucket is filled indicated by bubbles seizing coming out of the perforated tube the bottom tap is opened to allow water to flow into the next bucket and continued. The moment the tap is opened the water drains out sucking air in through the perforated tube. Thus the roots of the plant absorb nutrients from the waste water and air too and grow. ...

Termite mounds as hydrologic indicators(underwater indicators to dig wells and borewells) Varahamihira describes the possibility of water where ant hills are present. The termites in Sanskrit literature have been described as UPAJICA. Modern scientific studies reveal interesting facts authenticating the beliefs. In order to understand the significance of termite mound, a brief description of termites and its mounds, is a prerequisite. The termites live in 4 types of nest. One such type is the Epigeous nest ie, the nest built on the ground surface. All the termites are not mound builders and the only genus Copoterms of the family Rhinotermitidae build mounds. The epigeous nest is of importance for ground water exploration. High humidity is essential for the very survival of the species in arid and semi arid tracts. To maintain high humidity the termites have constant touch with ground water however deep it may be. The chief mechanism of the ter...
