Earth Tech, a business unit of Tyco Engineered Products & Services, and global provider of consulting, engineering and construction services, has been selected to design and construct four new wastewater treatment plants (WWTP) in Mexicali, Baja California, Mexico. The contract, which was awarded by the State Public Services Commission of Mexicali, is valued at US$22.5 million.
Earth Tech will design and construct a new WWTP facility in the city of Mexicali (Las Arenitas) that will treat 19 million gallons per day (980 liters per second).
Another facility in the suburban town of Guadalupe Victoria will process 1.6 million gpd (70 lps) and two smaller facilities in Estacion Coahuila and Los Algodones will each treat 0.5 million gpd (20 lps).
In addition, Earth Tech will expand two existing WWTPs. Ignacio Zaragoza in Mexicali will be increased from 22.4 million gpd (980 lps) to 30 million gpd (1300 lps). The capacity in another facility in the suburban community of Ciudad Morelos will be increased from 0.45 million gpd (20 lps) to 0.9 million gpd (40 lps).
In all, the six wastewater treatment plants will serve more than one million people in the city of Mexicali and the surrounding suburbs, and treat more than 50 million gallons per day once construction is finished in late 2006.
