Wastewater is the water we pour down the drain after use. It can come from our kitchens, from our bathrooms or from our toilets. This water is deemed to be waste due to the contaminants that we have added to the original incoming potable water supply.
In order to avoid returning wastewater to groundwater, rivers, lakes or the open sea it is necessary for it to be treated to remove contaminants and avoid any adverse effects on living creatures such as animals and fish or indeed humans who drink water directly from groundwater sources such as wells. The treatment for wastewater, also known as sewage, will involve a number of different stages. Normally, though, treatment of wastewater will involve just three distinct stages, primary, secondary and tertiary.
The Environmental Protection Agency here in Ireland has laid down some very strict procedures for the treatment of wastewater, especially for single dwellings not serviced by a municipal authority.
