In 2000, AECOM acquired Metcalf and Eddy, a water and wastewater engineering firm based in Massachusetts, [12] and in September, 2004 it acquired the Canadian company, UMA Engineering Ltd. [13] AECOM went public during May 2007 with an initial public offering on the NYSE, netting $468.3 million. [14]

Sewage treatment (or domestic wastewater treatment, municipal wastewater treatment) is a type of wastewater treatment which aims to remove contaminants from sewage to produce an effluent that is suitable to discharge to the surrounding environment or an intended reuse application, thereby preventing water pollution from raw sewage discharges.

In 1968—1969 a study conducted by Metcalf and Eddy, under the auspices of the State Water Control Board, determined that water quality deterioration in the reservoir was caused by substandard wastewater discharges from 11 secondary wastewater treatment plants and non-point sources of pollution. Following the commissioning of UOSA, the water ...
Metcalf & Eddy / AECOM (2014): “Wastewater is essentially the water supply of a community after it has been used in a variety of applications and which now contains constituents that render it unsuitable for most uses without treatment” Metcalf & Eddy use little the expression ‘sewage’, and employ more ‘domestic wastewater’.
Secondary treatment (mostly biological wastewater treatment) is the removal of biodegradable organic matter (in solution or suspension) from sewage or similar kinds of wastewater. [ 1 ] : 11 The aim is to achieve a certain degree of effluent quality in a sewage treatment plant suitable for the intended disposal or reuse option.

Most of the organisms involved are derived from the waste, wastewater or water stream itself or from the atmosphere or soil water. However some processes, especially those involved in removing very low concentrations of contaminants, may use engineered eco-systems created by the introduction of specific plants and sometimes animals.
