1.0 INTRODCUTION
Nearly 30% of the homes in the United States of America depend on onsite wastewater treatment and disposal. This percentage remained constant for the last two decades and is also estimated to be constant in the coming future.
It is estimated that up to one half of the septic tanks do not perform perfectly or may even fail even before their expected life. The risk of contamination of ground water and surface water quality increases with the failing of an onsite system. These result in degradation of water quality, health hazards, outbreak of diseases and lowered property values.
Nationally septic tank leachate is the most frequently reported cause for the contamination of the ground water and consumption of contaminated ground water is responsible for over 50% of all reported outbreaks of waterborne diseases.
Lack of affordable and effective onsite sewage disposal is a national issue. Less than 35% of the land in the United States of America is suitable for conventional septic tank soil absorption systems. These limitations
