Oil and grease separation unit with settling chamber would be good to reach some discharge standards to the municipal sewage network system, but this would be enough ? I assume that an advance treatment unit to remove the detergents would be better and a storage unit shall be installed to reuse the treated effluent for the same purpose (auto washing), I believe this will increase the cost of the unit however this will result in lower water bills and more sustainable
