Nearly 80 per cent of Sri Lankan population belongs to the rural sector. In most instances groundwater is utilized as the drinking water source in the form of ordinary shallow wells, deep wells and tube wells. Most of the
groundwater sources have high mineral contents such as iron and fluoride due to the hydrogeological features and
these need rectification. Considerable number of consumers belong to either the category of low income or to the less privileged group with poor educational background. In consideration with the said social factors an appropriate
village level treatment mechanism is necessary.
