Domestic pollution

Domestic water pollution is produced by the discharge of domestic sludge containing organic substances and soaps. These substances generally pour into superficial river flows but sometimes reach aquifers. It’s possible to reduce waste water pollution thanks to purification. Discharges are channelled from sewers to treatment stations to abate pollutants before discharging water into rivers and seas. These purification systems, though, aren’t always into force and, moreover, even where discharges are gathered and channelled can occur breaks or inefficies of septic pits, pipes or treatment plants that cause leakage of polluted water.
Also phytopurification, which uses specific plants that work as biological filters capable of reducing polluting substances, can be employed to abate pollutants present in waste water.
