GM de Mexico Ramos Arizpe Automotive Complex (RAAC) manufactures engines and passenger cars. Located in the northern part of Mexico, the RAAC water supply comes entirely from a subsurface aquifer whose drawdown rates presently exceed its recharge rate. The original wastewater treatment facilities, installed at the beginning of the RAAC operations, became inadequate as a result of more stringent wastewater discharge limits issued by SEDUE (Mexican EPA counterpart) in 1987 (see Table I). A Water Management Study was performed in 1986-7, to determine viable solutions to the problems of insufficient water supply and wastewater treatment. A three-phase Water Management Program was adopted.
