CH2M HILL lauded for noteworthy wastewater treatment projects
CH2M HILL, a consulting, design, construction, and operations firm, has been recognized with two Global Water Awards for its exceptional infrastructure work involving Peru's Taboada Wastewater Treatment Plant and the Bahrain Petroleum Company (BAPCO).
Peru's Taboada Wastewater Treatment Plant was named the Wastewater Project of the Year. The Taboada plant, located in Callao, Peru, is the largest water treatment facility in South America, with a maximum capacity of 1.8 million m3/d, and is part of the government's effort to improve water services in Lima, the world's second largest desert city after Cairo.
Prior to the facility being constructed, untreated sewerage was pumped into the sea. The treatment plant has helped transform Lima into a more sustainable city by delivering 75 percent of the city's wastewater back into the water cycle as treated effluent, compared to 16 percent. The mechanical treatment process employs 22 of the largest screening filters in the world, rough grates, and 1mm fine screening to treat effluent before it is discharged.
Accordingly, BAPCO received an Award of Distinction for the Industrial Project of the Year for its $120-million wastewater treatment facility, which treats 24,000 m3/d of secondary wastewater at the BAPCO refinery in Sitra, Bahrain. The four-stage MBR process treats water to industrial reuse standards, meeting very stringent nitrogen and phosphorous discharge limits. The plant includes an innovative double stage cooling of wastewater from 48 to 35℃ and the green and sustainable reuse of the spent caustic as a source of nutrients for the biomass.
