Sewage and Wastewater Treatment

SEWAGE AND WASTEWATER TREATMENT

Although the major focus in sanitation has been on preventing human contact with fecal coli forms and other pathogens by far the major pollutant in sewage and wastewater is nutrients. Effective treatment systems will not only separate people from disease carrying organisms, they will also harvest nutrients out of sewage and wastewater.  

HOUSEHOLD ON-SITE TREATMENT SYSTEMS

Poor, or non-existent, sanitation and its corollary, lack of safe drinking water are the biggest causes of sickness and disease in the tropical developing world. Urban communities may eventually be served by centralized sewage systems, but in rural areas, where centralized facilities are out of the question, there is an urgent need for low-tech, low-cost household treatment systems.   

Recently, perhaps for the first time, biological treatment systems using plants to harvest nutrients have been installed on a large scale. Subsurface flow wetlands and/or vegetated leach fields are currently being installed in thousands of rural homes under reconstruction in tsunami-affected Aceh.

Vetiver grass is being widely used in wetlands and leach fields in Aceh for two main reasons.  

Firstly, although wetland plants, reeds, rushes and cattails, are usually recommended, Acehnese living in wetland environments view these plants as invasive weeds and as such they are not acceptable in household gardens.  

Secondly, vetiver has the desired characteristics needed in biological treatment systems. It has a massive root system, which effectively harvests nutrients, it produces biomass quickly and it can live in high moisture and nutrient rich environments.
