A very common system to treat wastewater, both in rural and urban areas (increasingly less) is the septic tank, sometimes joined with an added filtration system. Wastewater is extracted by tankers and transported to authorized sewage treatment plants. It is highly advisable to hire a specialized company such as PELE CANO, which empties by pumping, and transport of wastewater from your well or septic tank, given that certain standards must be met with the resulting waste.
