Abstract: The ability of aquatic macrophytes to accumulate large quantities of nutrients from their environment is well documented. Reed Bed Combination Techniques for the treatment of the different types of wastewater have been used by several Researchers / Scientists all over the world. This concept has the potential to achieve a zero discharge wastewater treatment system. Man has always reached for technology for development. He insists it will bring higher levels of progress. But doesn’t have the patience to study the slow-growing plants nor does he understands the natural cycles. Schoenoplectus lacustris (L.), Palla (old designation Scirpus lacustris) species is capable of “removing large quantities of organic and inorganic substances from contaminated waters” proved by the research of Dr. Kaethe Seidel in 1953 [5]. She had also shown that they take up large quantities of Ballast substances including Cobalt, Copper, Nickel and Manganese from sewage water and other higher plants, including the common reed, Phragmites communis Trin, are capable of drying out and mineralizing assorted sludge combinations which are difficult to remove. The almost water-free residues contain very little if any dangerous bacteria. This technique is an Engineered Wetland System developed on the principle of Natural Wetland. This paper will discuss the potential widespread of similar systems where there is no infrastructure for Municipal waste Disposal. The Development of an appropriate Zero Discharge wastewater facility has the potential to address the source of Environmental pollution in India
