Septic tank systems are the most widely used systems for treatment and disposal of domestic wastewater around the world, follow me as I will be sharing briefly on the impact caused by septic tank systems in my surrounding which is geographically located between latitude N4,154181 to longitude E 9,275779 on the earth surface.

         Most of the septic tank systems is due to their simplicity, low costs and treatment.However, their function is highly variable and they often produce effluent(liquid waste) with different quality.Septic tank systems often fail due to aging, negligence of the user, poor management and lack of maintenance thereby, posing risk to surface and ground water quality.This is because septic tank effluent contains a wide variety of pollutants such as, pathogens, faecal bacteria, phosphorus, nitrogen, organic matter, suspended solid, pharmaceutical compounds, household detergents and other chemicals that poses risk to freshwater resources. As a result, it causes ecological Impact on water quality.

     Other studies have shown that wastewater which is been discharge from the septic tanks causes greater risks to water quality than agricultural diffuse source.

     To conclude, it is important to evaluate septic tank system discharges and to understand their loading Impact to place them in perspective with other rural diffuse pollution source in order to prioritise and target effective mitigation measures.
